- Review of the indications for periodontal regenerative therapy, including diagnostic assessment and the conditions that should be achieved through initial periodontal therapy before treatment.
- Effective flap designs for various types of vertical bone defects and the criteria for selecting the appropriate approach.
- Current concepts in periodontal regenerative therapy for furcation defects, with a focus on flap design.
- 歯周組織再生療法の適応症を整理し、見極めるための診査や歯周基本治療にてクリアすべき条件をレビューします。
- 多種多様な垂直性骨欠損に対する効果的なフラップデザインとその選択基準を提示します。
- 根分岐部病変に対する歯周組織再生療法の最前線について、フラップデザインから考察します。
Periodontal regenerative therapy is an essential periodontal surgical procedure for preserving teeth and improving their long-term prognosis. However, successful outcomes depend on appropriate case selection and advanced surgical skills. This lecture will review the indications for periodontal regenerative therapy and outline the key factors that should be evaluated during the preoperative examination and initial periodontal therapy. In addition, effective flap designs for various types of vertical bone defects, together with the criteria for their selection, will be presented through clinical cases. The potential and limitations of regenerative therapy for furcation defects will also be discussed from the perspective of strategic flap design, with practical clinical insights shared to help achieve more predictable treatment outcomes.

Clinical Strategies for Improving the Predictability of Periodontal Regenerative Therapy
歯周組織再生療法における再現性向上のための臨床戦略
- Predictable Access to Severe Bone Defects and Root Surfaces
- An Interdental Papilla Approach Based on Histological Principles
- Key Factors for Achieving Stable Clinical Attachment Gain
- 重度骨欠損と歯根面への確実なアクセス
- 組織学的理論に基づく歯間乳頭へのアプローチ
- 安定したクリニカルアタッチメントゲインを得るためのポイント
Increasing emphasis has been placed on minimally invasive surgical approaches and flap designs aimed at preserving the interdental papilla. Nevertheless, the achievement of stable clinical attachment gain is influenced not only by surgical techniques and regenerative materials, but also by biologically driven surgical principles, including maintenance of vascularity, preservation of interdental papillary thickness, and stability of the supracrestal tissue complex.
Moreover, regenerative therapy is frequently indicated for anatomically complex osseous defects, in which adequate access to the root surface and defect morphology must be carefully balanced with wound stability to optimize regenerative outcomes.
This presentation will introduce biologically driven approaches to papillary management, incision and flap designs based on defect morphology, and clinical perspective utilizing an operating microscope. Clinical strategies aimed at enhancing predictability in periodontal regenerative therapy will be discussed through the presentation of surgically challenging cases.

Is the success of periodontal regenerative therapy determined primarily by surgical skill or by material selection?
- Periodontal regenerative therapy
- Growth factors
- Bone graft substitutes
Periodontal regenerative therapy is defined as the histologic regeneration of the tooth-supporting apparatus, including cementum, periodontal ligament, and alveolar bone. Clinical outcomes have improved with advances in biomaterials, such as enamel matrix derivative (Emdogain®), basic fibroblast growth factor (Regroth®), and various bone graft substitutes.
Recent evidence suggests that adherence to fundamental surgical principles—such as wound stability, clot protection, and minimally invasive flap design—may exert a greater influence on clinical outcomes than the choice of regenerative material itself. In particular, in the treatment of intrabony defects, accurate assessment of defect morphology, appropriate flap design, and precise suturing to ensure primary wound closure are considered critical determinants of prognosis.
Conversely, in defects with limited bony walls, material selection also becomes an important factor. Therefore, successful periodontal regeneration requires both biologically based surgical techniques and material selection tailored to defect configuration.
In this lecture, periodontal regenerative therapy will be discussed from basic research to clinical applications, incorporating representative clinical cases to facilitate discussion.
