Abstract
From Biofilms to Data-Driven Diagnostics
Understanding of oral disease has evolved from a simplistic plaque-centric paradigm to a sophisticated model recognising dysbiotic biofilms as dynamic, host-modulated ecosystems. Dental biofilms are no longer viewed merely as accumulations of microorganisms but as complex, structured communities interacting with host immunity, environmental exposures, and systemic health. This ecological shift in thinking has laid the foundation for a broader diagnostic revolution.
Advances in microbiomics, metagenomics, and salivary biomarkers now enable detailed characterisation of biofilm composition, functional activity, and virulence potential. When integrated with artificial intelligence and big data analytics, these datasets allow risk stratification, early disease prediction, and personalised preventive strategies. Digital imaging, chairside biosensors, and longitudinal patient data further enhance our capacity to detect transitions from symbiosis to dysbiosis before irreversible tissue damage occurs. The exposome framework adds another critical dimension, linking biofilm behaviour to diet, lifestyle, socioeconomic determinants, and environmental exposures.
Together, these innovations transform biofilms from static pathological entities into measurable, predictive indicators within precision oral health models. This presentation examines how dysbiotic biofilms serve as both the biological driver and the analytical substrate of data-driven diagnostics, redefining oral pathology in the era of systems biology and digital intelligence.

Abstract
Biofilm management in restorative dentistry
Advances in the understanding of dental caries have shifted restorative dentistry toward biologically informed strategies, with Minimal Intervention Dentistry (MI) becoming a key guiding philosophy. MI focuses on two main components: effective management of the cariogenic biofilm and the use of minimally invasive restorative techniques, particularly when addressing the infected layer of advanced lesions. Developments in bioactive materials now support tissue preservation and promote remineralisation, extending conservative treatment possibilities even in deep caries.
Debate persists regarding the best approach to managing bacteria within infected dentine. However, improved insight into the interaction between oral microbial ecosystems and host tissues has informed more targeted and predictable strategies for deep lesion management, enabling reduced removal of sound tooth structure.
This presentation will provide an integrated overview of MI principles, highlight clinical techniques for early intervention and biological caries control, and outline the materials and decision-making frameworks essential for applying minimal intervention dentistry in modern practice.

Abstract
Endodontic biofilms develop by microbial invasion and colonisation of the pulpo-dentine complex and involve complicated interactions between microbial and host factors leading to various endodontic conditions. The endodontic biofilm primarily develops as an extension of a dentine biofilm from the clinical crown of a tooth subsequent to a breach in the structural integrity of enamel and/or dentine by dental caries, the restoration-tooth interface, dental trauma, tooth cracks/fractures or from exposed root structure.
This presentation will discuss the microbial and host defence factors involved in development of the endodontic biofilm and colonisation of the root canal system and radicular dentine and its effects on the dental pulp and periradicular tissues with a focus on contemporary clinical concepts for the management of the endodontic biofilm in vital pulp therapy, conventional root canal treatment and regenerative endodontic therapy.

Abstract
Bacterial ecosystems and oral tissue have co-existed in a synergistic symbiosis for as long as humans existed. Inflammation, the cornerstone process of the immune system has always been the expression of a delicate balance; either extending protection or at times destruction of oral tissue. Advancing biological understanding and technology in dentistry has helped to develop effective treatment strategies for plaque induced inflammations of oral tissue such as Periodontitis. At the same time, bio-technological advances in rehabilitation such as dental implants have also introduced new therapeutical challenges.
Dental Implants are no longer perceived as metal constructions passively anchored in bone. On the contrary, implant-supported prostheses are shown to be complex biologically active systems, which constantly interact with human tissue and microbes, supporting function and aesthetics in a delicate balance between biology and technology. It is exactly this interrelation between living tissue and precisely constructed biomaterials that determines long term success or complications. Critical parametres from the implant, the microbia, the local anatomy and tissue as well we the patient are in a constant dynamic balance. Maintaining this balance as a symbiosis is the critical determinant between health and disease and our major responsibility today as clinicians. Proper treatment plan and design of the implant-prosthesis-tissue complex coupled with a careful individualized maintenance schemes are the keys to ensure long term successful clinical outcomes.
In this presentation, we will dissect the problem of Peri-implantitis and dissect the clinically relevant parametres which can prevent or predispose peri-implantitis. We will identify the interactions that take place between the microbia, the implant components and the peri-implant tissue in the light of the latest scientific evidence and finally identify clinical strategies for prevention or early identification and treatment of Mucositis and Peri-implantitis.

Abstract
In Japan, long-standing efforts to prevent dental caries and periodontal disease have led to substantial improvements in oral health. As a result, the “8020 Campaign” has achieved remarkable success, with more than 60% of older adults retaining 20 or more natural teeth at the age of 80 as of 2024. However, it has also become evident that even when the number of remaining teeth is maintained, a certain proportion of older adults experience difficulties in “eating and speaking” due to declines in oral functions such as mastication, swallowing, and articulation. This highlights that the goal of dental care has reached a stage where it should shift from simply maintaining the number of teeth to preserving and improving oral function.
Against this background, Japan has implemented several new strategies focusing on oral function. First is the concept of “oral frailty,” proposed as a population-based approach. This concept identifies the accumulation of subtle declines in oral function as an early warning sign of future frailty. Initiated by the Kanagawa Dental Association, it has been widely disseminated and socially implemented through collaboration with the Japan Dental Association and related academic societies. Second is “oral hypofunction,” a diagnostic category introduced into the national dental insurance system in 2018. This globally unique system enables objective assessment, diagnosis, and intervention for oral function, thereby formally positioning functional management within clinical dental practice. Third is the “oral function improvement service” under the long-term care insurance system, which focuses on prevention and targets older adults requiring care.
This lecture will provide an overview of these three key strategies and discuss the current status and significance of oral function management for older adults in Japan. It is my sincere hope that Japan’s experience will offer valuable insights for our colleagues in Vietnam, where population aging is rapidly progressing.

Abstract
As global populations continue to age, dental clinicians increasingly encounter elderly patients requiring complex treatment planning. Japan, one of the most rapidly aging societies in the world, entered a super-aged society in 2007, with more than 29% of its population currently aged 65 years or older. In contrast, Vietnam has recently entered an aging society and is expected to experience population aging at an even faster rate in the coming decades. These demographic changes will inevitably influence dental treatment needs and strategies.
While implant therapy is frequently considered the first-line treatment for tooth loss, treatment planning for elderly patients requires careful consideration of biological limitations, treatment duration, and overall Quality of Life. Age-related changes in bone metabolism, systemic health conditions, and periodontal disease often complicate Prosthetic rehabilitation. In many elderly patients, Pathologic Tooth Migration (PTM) further alters occlusal relationships and prosthetic conditions.
Limited Orthodontic Treatment (LOT) offers a valuable adjunctive strategy in such situations. By correcting localized tooth displacement, improving prosthetic conditions, and optimizing occlusal relationships, LOT can enhance implant treatment planning and reduce surgical invasiveness. Orthodontic movement may also facilitate space creation, improve implant positioning, and support functional rehabilitation in elderly patients.
This presentation discusses treatment strategies for elderly patients in the context of a super-aging society, focusing on the clinical integration of LOT with implant therapy. Several clinical cases will be presented to demonstrate how combining orthodontic and implant approaches can improve treatment predictability and patient quality of life in aging populations.

Abstract
The use of IPG has significantly reduced the number of mismatches in long-distance bridges, which has been a challenge for conventional IOS. In particular, in the data migration from provisional to final, accurate location information can be maintained without re-scanning, which can be expected to shorten chair time and improve the efficiency of technician operations. In addition, it is likely to be an essential tool for obtaining a highly accurate passive fit in full-arch cases, and as a highly accurate digital mounting protocol, it is expected to improve its reliability in clinical practice.

Abstract
Recent advances in implant dentistry have introduced a wide range of techniques for full-arch rehabilitation, expanding both treatment options and clinical decision-making pathways. This presentation reviews contemporary approaches and critically compares their clinical outcomes with traditional restorative techniques.
In recent years, implant protocols have evolved beyond the classical All-on-4 concept toward more flexible “All-on-X” strategies, allowing clinicians to adapt implant number and positioning according to individual anatomical and functional requirements. This paradigm shift reflects a broader movement toward personalized, prosthetically driven implant planning.
The lecture will explore the full spectrum of full-arch rehabilitation strategies, from bone augmentation and grafting procedures to graftless approaches. Particular emphasis will be placed on remote implant anchorage, biomechanically optimized implant distribution, and minimally invasive alternatives designed to reduce morbidity while maintaining long-term success.
By integrating evidence-based principles with contemporary digital planning and surgical techniques, this presentation aims to support clinicians in selecting the most appropriate treatment modality for complex full-arch cases.

Abstract
Background and Objective(s): Pterygoid implants represent an effective solution for rehabilitation of the posterior maxilla, particularly in cases of severe bone resorption or maxillary sinus pneumatization. However, this technique is considered technically demanding and highly dependent on patient-specific anatomical conditions. This presentation aims to analyze the challenges of placing pterygoid implants in Vietnamese patients from both anatomical research and clinical perspectives. Content: The presentation focuses on anatomical characteristics commonly observed in Vietnamese patients that may influence pterygoid implant placement, including low bone density in the maxillary tuberosity, the degree of maxillary sinus pneumatization, the morphology of the pyramidal process of the palatine bone, and the trajectory of the pterygoid implant. In addition, clinical challenges such as achieving adequate primary stability and factors affecting treatment predictability during pterygoid implant placement in Vietnamese patients are discussed. Clinical strategies to optimize implant trajectory, enhance initial stability, and minimize potential complications are also presented. Conclusion(s): A thorough understanding of the anatomical characteristics of the pterygoid region in Vietnamese patients and careful CBCT-based treatment planning are essential for improving surgical safety and predictability in pterygoid implant therapy.

Abstract
Severe maxillary bone resorption following complete tooth loss presents a major challenge in implant rehabilitation, particularly in cases of advanced atrophy. Two principal treatment strategies are currently employed: bone grafting to reconstruct the alveolar foundation and graftless approaches that maximize the use of residual bone. However, the optimal choice in specific clinical scenarios remains a subject of ongoing debate.
The objective of this presentation is to clarify the criteria for selecting between grafting and graftless approaches in the management of the edentulous maxilla, based on scientific evidence integrated with clinical experience.
This presentation synthesizes current literature and illustrates key concepts through representative clinical cases. Bone grafting enables prosthetically driven implant placement and is indicated in cases of moderate atrophy with high esthetic demands; however, it is associated with longer treatment time and increased risk of complications. In contrast, graftless solutions—such as tilted implants, pterygoid implants, and zygomatic implants—reduce treatment time and surgical invasiveness, making them particularly suitable for severe atrophy. These approaches, however, require advanced surgical expertise and careful management of technique-specific complications.
Treatment decisions should be guided by prosthetic objectives, anatomical conditions, and patient-related factors. Current trends emphasize personalized treatment planning, the integration of digital workflows, and minimally invasive strategies while maintaining long-term predictability.

Abstract
Background and Objectives
Open sinus augmentation is a key procedure in implant rehabilitation of the posterior maxilla. However, in clinical practice, not all cases achieve the expected graft volume, which may necessitate modifications of the treatment plan and affect implant prognosis. This report aims to analyze the causes of graft volume deficiency following open sinus lift from the surgeon’s perspective, focusing on the clinical decision-making pathway.
Content
the presentation reviews the entire treatment process, from preoperative assessment (CBCT imaging, sinus anatomy, bone quality, and soft tissue conditions), selection of surgical technique, grafting strategy, to postoperative follow-up. Rather than emphasizing purely biological factors, the report highlights strategic deviations in planning and execution, including case selection, volume prediction, space maintenance, and complication management. Based on this analysis, the report raises a critical question: “Where did we go wrong in the clinical decision chain?”
Conclusion
Understanding and controlling surgeon-related factors — particularly in treatment planning and technical execution — is crucial for optimizing graft volume outcomes and improving implant prognosis in the posterior maxilla.

Abstract
The digital scanning of full-arch implant cases presents a multifactorial challenge that continues to frustrate many practitioners. Achieving precise capture of implant positions is particularly demanding, as even minor inaccuracies can compromise the passivity and long-term success of the restoration. The inherent mobility and compressibility of peri-implant soft tissues further complicate the scanning process, often leading to distortions that negatively affect both scan quality and clinical outcomes. Additionally, bite registration in these complex cases remains a persistent source of error, given the difficulty of accurately recording occlusal relationships in patients with extensive implant-supported prostheses.
This lecture addresses these critical issues by offering a structured, evidence- based mindmap designed to guide clinicians through the optimization of soft tissue management, implant position scanning, and bite registration techniques. By integrating practical strategies and digital workflows, the session aims to enhance accuracy, predictability, and efficiency in the digital capture of full-arch implant cases, ultimately improving restorative outcomes in challenging clinical scenarios.

Application of the Modified Tunnel Technique in the Treatment of Gingival Recession Around Natural Teeth and Peri-implant Soft Tissue Defects
CV
Educational Background:
– Received DDS degree from Ho Chi Minh City Medicine and Pharmacy University in 2016
– Received Master Clinician in Implant Dentistry Certificate from gIDE Institute and Loma Linda University
Current Affiliation:
– Clinical director of Elite Dental Metropole
Abstract
The tunnel technique is a treatment method for gingival recession and soft tissue deficiencies based on a closed-flap mechanism, offering the advantage of optimal papilla preservation compared to the Coronally Advanced Flap (CAF) technique, and is particularly effective in cases with interproximal attachment loss classified as RT2, RT3 (Cairo 2011). However, the limitation of this method lies in the demanding requirement for specialized instrumentation and the high risk of flap tearing during manipulation.
This presentation introduces the Modified Tunnel Technique (Modified VISTA) with minimal vertical mucosal incisions, which optimizes flap control and enables a faster and safer procedure. Through illustrative clinical cases, the presentation will demonstrate the effectiveness of this technique in treating RT2, RT3 gingival recession on natural teeth, as well as in managing esthetic complications involving peri-implant papilla loss, providing attendees with a more detailed understanding of the procedural workflow and appropriate clinical indications.

Abstract
Background and Objectives
Barrier membrane selection is a key factor for predictable outcomes in Guided Bone Regeneration (GBR). Non-resorbable membranes such as PTFE provide excellent space maintenance but are associated with complications including exposure and the need for a second surgery. Thick cross-linked bovine pericardium membranes have been introduced as a resorbable alternative capable of combining mechanical stability with favorable biological behavior.
Content
Recent clinical studies and case series have evaluated bovine pericardium membranes in socket preservation, periodontal regeneration, sinus augmentation and GBR procedures. Their multi-laminar collagen-elastin structure provides high tensile strength, good suturing resistance and prolonged resorption time when cross-linked. Clinical evidence shows predictable horizontal bone gain and moderate vertical augmentation when used with particulate grafts and membrane fixation. Compared with non-resorbable barriers, pericardium membranes demonstrate a more favorable healing profile and reduced complications in case of membrane exposure.
Conclusions
Cross-linked bovine pericardium membranes represent a reliable resorbable option for horizontal and moderate vertical bone augmentation, offering predictable outcomes while reducing patient morbidity and eliminating the need for membrane removal.

Abstract
Gingival recession is a common condition in periodontal practice, leading to root exposure, dentin hypersensitivity, and esthetic concerns. Numerous surgical techniques have been developed to achieve root coverage and improve esthetic outcomes, ranging from traditional pedicle flaps to more advanced procedures such as the coronally advanced flap combined with connective tissue graft (CAF + CTG) and the tunnel technique. However, selecting the most appropriate treatment approach for each clinical case remains challenging and requires consideration of multiple factors, including the classification of gingival recession, periodontal phenotype, soft tissue thickness, and local anatomical and functional conditions.
This presentation aims to provide an overview of commonly used gingival recession classifications, current surgical techniques for root coverage, and recent advances in periodontal plastic surgery. In addition, it proposes a clinical approach to selecting appropriate gingival grafting procedures based on specific clinical situations and current scientific evidence. Several clinical cases will also be presented to illustrate the diagnostic process, treatment indications, and clinical outcomes achieved in daily practice.

Abstract
In contemporary implant dentistry, soft tissue grafting plays a pivotal role not only in enhancing esthetic outcomes but also in ensuring the long-term stability of peri-implant tissues. However, achieving effective hemostasis during and after surgery remains a significant challenge, potentially compromising blood clot stability, graft integration, and the overall healing process. Conventional hemostatic approaches primarily rely on mechanical methods or absorbable materials, which may be limited in maintaining an optimal healing environment. Recently, cyanoacrylate-based biological adhesives have emerged as a promising adjunct due to their ability to form a protective barrier, stabilize blood clots, and shield the surgical site. This paper aims to critically evaluate the role of biological adhesives in optimizing hemostasis and improving clinical outcomes in implant-related soft tissue grafting.

Abstract
Autogenous soft tissue grafting has increasingly become an integral component of contemporary implant therapy. Soft tissue augmentation is no longer considered merely a corrective procedure for complications, but rather a proactive therapeutic approach aimed at optimizing biologic conditions, enhancing esthetic outcomes, and improving the long-term predictability of implant treatment. However, no single soft tissue grafting technique is universally applicable to all clinical situations. The selection of surgical techniques should be individualized according to the specific soft tissue deficiency and the intended treatment objectives. Free gingival grafts are commonly indicated for increasing the width of keratinized mucosa and improving peri-implant plaque control, whereas subepithelial connective tissue grafts are regarded as the gold standard for enhancing soft tissue thickness and optimizing esthetic outcomes. Techniques such as roll flaps and pedicle flaps are particularly suitable for mild to moderate soft tissue volume deficiencies, allowing refinement of peri-implant soft tissue contours. Therefore, the success of soft tissue augmentation depends not only on whether grafting is performed, but more importantly on selecting the appropriate technique, at the appropriate timing, and for the appropriate clinical indication in order to achieve long-term biologic stability, functional success, and esthetic integration around dental implants.
Based on these considerations, this presentation aims to review the role of autogenous soft tissue grafting around dental implants, while analyzing the optimal timing and appropriate surgical techniques to maximize biologic, functional, and esthetic outcomes.

Abstract
Restoring a natural looking tooth with dental implant could be either a challenging task or a comfortable work. Especially in the esthetic zone, when patients tend to have a higher expectation for results yet lower threshold for pain and morbidity. It consists of mental, economical, dental and periodontal battles against sophisticated tissue management and precision implant placement.
The re-creation or retention of a normal alveolar contour with covering soft tissue should follow the following 5 key fundamental elements according to Dr. Sascha A. Jovanovic:
1. Bone foundation
2. Implant design and position
3. Soft tissue Profile
4. Prosthetic Tissue Support
5. Ceramic art design
It is the purpose of this presentation to focus on the above 5 key factors for accomplishing such tasks.

Abstract
Traditional methods of diagnosing root canal sensitivity by thermal and electrical testing have been commonly used in clinical practice due to their simplicity and accessibility, but are methods of evaluation through a neurostimulus response. Using Doppler Laser to assess marrow vitality includes measuring marrow blood flow, measuring blood oxygen saturation, and measuring tooth temperature, which is a direct measure of marrow life.
The working principle of Doppler Laser: A beam of laser light with low power (2 – 3 milliwatts) is guided by an optical fiber to the probe, when the probe comes into contact with the tissue area to be evaluated (skin, teeth, etc.), the laser light will penetrate with depth depending on the wavelength and tissue type. Here, the light from the Doppler Laser blood flow meter is scattered by both stationary tissue and moving blood cells (where red blood cells are the dominant component in size and number). With the erythrocyte cell in motion, the scattered light appears to have a Doppler frequency change, which decreases by about 4kHz for every 1 mm/s of velocity out of the light source; In contrast, stationary structures do not produce this change.
The output data of the machine usually includes: perfusion value (flux), average velocity, and cell density. In particular, the perfusion value, also known as pulp blood flow (PBF unit: PU), is directly proportional to the velocity and density of cells moving through the surveyed tissue. Using a Doppler Laser blood flow meter does not create any harmful stimuli, so it is easy to get the approval of patients, especially those who are prone to anxiety and stress such as children or people with special care needs. The method of assessing tooth pulp life by Doppler Laser is objective because it does not depend on the patient’s reaction or pain sensitivity.
The Doppler Laser Blood Flow Measurement (LDF) technique used to directly assess the perfusion status of medullary tissue, is a non-invasive and highly reliable method, which has initially established the reference value of pulp blood flow (PBF) of permanent tooth groups in Vietnamese adults.

Bioceramic- Revolution in conservative dentistry
CV
– A.Prof. Tran Xuan Vinh, DDS, PhD is the Head of department of basis sciences at the University of Medicine and Pharmacy at Ho Chi Minh City (UMP).
– He obtained his PhD, MSc and the Certificate in Dental Biomaterials at Paris V University in France.
– He got the Certificate in Dental Implantology at Pitié Salpêtrière hospital, Paris VI University in France.
Abstract
The introduction of bioceramic materials marks great advance for conservative dental therapy. Bioceramics are classified as: bioinert, bioactive, and biodegradable. With predominant physicochemical properties and biocompatibility, many bioceramic materials are used in medicine. Bioactive calcium silicate can be used as a filling material, root repair, or root canal sealer. Applied to vital pulp therapy, bioceramic materials can be used in cases of pulp exposition from trauma, caries or other mechanical causes, as direct pulp capping or pulpotomy. Bioceramic is also recommended as a root canal sealer in endodontic treatment of teeth with periapical lesions.

Abstract
For decades, endodontic treatment has relied primarily on clinical experience and 2D radiographic imaging. The limited visualization of complex anatomical structures has created a demand for more precise interventional solutions. Modern endodontics is witnessing a paradigm shift from traditional to personalized treatment models, driven by digital integration. AI-powered software assists in 3D anatomical reconstruction from CBCT data, enabling early detection of canal variations, calcifications, and vertical root fractures. The implementation of 3D-printed models allows clinicians to simulate and perform clinical trials prior to intervention, minimizing complications and optimizing instrument selection. Furthermore, the advancement of bioceramic materials and MTA facilitates personalized material selection based on the specific biological and anatomical needs of each tooth. Notably, regenerative endodontics paves the way for functional preservation through the restoration of the vital pulp-dentin complex. This presentation demonstrates how the synergy of CBCT, AI, 3D printing, and modern biomaterials is shaping the future of endodontics toward maximum preservation, where advanced technology serves as a powerful tool to enhance treatment outcomes and patient care.

Abstract
Prosthodontics is undergoing a significant transformation driven by technological advancement, novel biomaterials, and increasing aesthetic demands. From a traditional tooth-replacement approach, contemporary prosthodontics has shifted toward comprehensive rehabilitation of the masticatory system, integrating functional, biological, and aesthetic considerations.
Digital dentistry, including CAD/CAM systems, intraoral scanning, and 3D printing, is becoming a core platform that enhances accuracy, efficiency, and treatment individualization. Dental implants remain a cornerstone in the management of complex and full-arch rehabilitations, while minimally invasive and tooth-preserving approaches are increasingly prioritized. Nevertheless, challenges persist, including variability in clinical quality, limitations in advanced prosthodontic training, and the risk of overtreatment under commercial pressures. These issues highlight the need for standardized clinical protocols, continuous professional development, and strengthened ethical governance.
The future direction of prosthodontics lies in a holistic, interdisciplinary, and patient-centered model of care aimed at achieving predictable, durable, and sustainable outcomes.

Abstract
Anxiety and fear are normal human emotions when perceiving a real or potential threat. Dental phobia is a sympathetic nervous system response to potentially threatening stimuli in a dental situation, a common problem in dental clinics leading to patients becoming tense in the chair and avoiding dental care. In practice, treating patients with this phobia is a tiring experience for both dentists and patients. This article introduces the causes, classification, and assessment methods of dental phobia, the impact of fear on the patient’s physiology during treatment, and some strategies for managing the fear.
