Critical Turning Points Between Success and Failure in Restoring Smiles for Patients with Severe Alveolar Bone Defects

重度歯槽骨欠損を有する患者の笑顔を取り戻す成功と失敗の分岐点

Leading periodontists from both clinical practice and academia will come together to discuss the treatment of patients with severe periodontal disease. Drawing on the latest research, the speakers will explain the reasoning behind their clinical decisions, including why specific treatment plans and flap designs were chosen. This session is ideal for clinicians looking to strengthen their periodontal knowledge, as well as those seeking new insights to apply in daily practice.

Treatment Strategies for Severe Alveolar Bone Loss: A Long-Term Perspective

Differences between horizontal and vertical bone loss
The importance of establishing physiological alveolar bone morphology
The need for definitive surgical treatment (re-entry surgery)
Occlusal force control through periodontal prosthetic treatment

Successful treatment of periodontal patients with severe alveolar bone loss requires careful attention not only to the control of inflammation but also to the management of occlusal forces. Various factors, including the morphology, severity, and extent of bone defects; the number, distribution, and condition of the remaining teeth; the magnitude of occlusal forces; and intermaxillary relationships, can significantly influence treatment planning. Accurate examination and diagnosis of these factors, together with appropriate treatment, are essential for the long-term stability of treatment outcomes. Furthermore, patient understanding and cooperation, as well as a strong relationship of trust between patients and dental professionals, are indispensable. In this lecture, I will review long-term clinical cases and discuss the concepts and approaches necessary to achieve a favorable prognosis.

Clinical Evidence and Biological Optimization in Periodontitis Treatment: Optimizing the Use of Biomaterials

Biological processes underlying the progression and healing of periodontitis, and the fundamental principles of periodontal regeneration
Success factors and limitations of periodontal regeneration based on current clinical evidence
The role of biomaterials in periodontal regeneration and their optimal clinical application based on material characteristics
Future directions in periodontal regenerative therapy

The success of periodontal therapy depends on a thorough understanding of biological principles and precise clinical decision-making tailored to each individual case. This lecture will review the biological basis of periodontal regeneration and the wound-healing process, followed by an overview of current recommendations and supporting evidence from major professional organizations. Success factors and limitations of periodontal regenerative therapy will be discussed from an evidence-based perspective. Particular emphasis will be placed on the clinical application of biomaterials, including enamel matrix derivative (EMD) and fibroblast growth factor-2 (FGF-2), in patients with severe alveolar bone defects. Their indications, use in combination with bone graft materials, and the latest evidence regarding drug delivery effects will be critically examined. By considering biomaterials as tools for biological optimization, this lecture will explore the importance of modulating host responses from the perspective of precision periodontology and discuss how current evidence can be translated into optimal clinical practice.

Advances in periodontal regenerative therapy have made outcomes more predictable. A significant recent development is the flap design that avoids_interdental papilla incisions, enabling access to bone defects_from the buccal side_through a tunnel approach. To expand its indications, we introduced the Double Sided Entire Papilla Preservation Technique. Additionally, we developed the Supra-alveolar Periodontal Tissue Reconstruction Technique to improve multiple vertical hard and soft tissue defects, previously considered impossible to address. This presentation focuses on hard and soft tissue management in the esthetic zone, showcasing these techniques for both natural teeth and peri-implant tissue regeneration.
