Advantages of Periodontal Microsurgery in the Esthetic Zone
審美領域における歯周マイクロサージェリーの利点

- 歯周組織の顕微外科手術
In modern dental practice, comprehensive diagnosis and treatment planning based on an interdisciplinary approach are essential. The goal of dental treatment is to resolve patients’ chief complaints while improving quality of life (QOL) and achieving esthetic satisfaction. Patient demand for esthetic treatment has increased in recent years. In addition to “white esthetics,” such as tooth color and shape, greater attention is now given to “pink esthetics,” which focuses on harmony between the teeth and surrounding soft tissues. To meet these expectations, periodontal plastic surgery must use techniques that minimize postoperative esthetic problems, including scar formation and unfavorable changes in gingival contour. Periodontal microsurgery provides a precise and minimally invasive approach to achieve these goals. This presentation outlines the basic concepts of periodontal microsurgery and demonstrates its clinical application within an interdisciplinary approach through representative cases.

From Hopeless to Hopeful: A Tooth Preservation Strategy for Compromised Teeth
From Hopeless to Hopeful:
保存不可能と思われた歯を、保存可能な歯へ導く治療戦略
- 保存不可能と診断された歯であっても、動的かつ段階的な診断と再評価によって、保存可能となりうる。
- エンドペリオ病変に対しては、三次元的診断に基づき、歯内療法と歯周組織再生療法を段階的に行うことが重要である。
- エンドペリオ病変に対する歯周組織再生療法において、サイトランスグラニュールとFGF-2は有効な治療選択肢となりうる。
The diagnosis of “hopeless teeth” has traditionally been regarded as an indication for extraction. However, recent advances in periodontal regenerative therapy and contemporary endodontic treatment have prompted a re-evaluation of conventional extraction criteria. This presentation reports a series of cases in which teeth diagnosed with a hopeless prognosis were successfully preserved through an interdisciplinary approach combining periodontal regenerative therapy and endodontic treatment. Comprehensive diagnostic assessments were performed to evaluate tooth preservability and the presence of combined periodontal and endodontic pathology. Endodontic and periodontal conditions were assessed independently using conservative diagnostic criteria, with particular emphasis on three-dimensional evaluation of lesion complexity. Cases were carefully selected based on the potential for infection control and biological reversibility. Treatment protocols consisted of meticulous endodontic disinfection followed by periodontal regenerative procedures targeting intrabony or furcation defects. Post-treatment evaluations demonstrated resolution of clinical symptoms, improvement in periodontal parameters, and radiographic evidence of stabilization or regeneration of supporting tissues, allowing functional maintenance of the treated teeth during the observation period. These findings suggest that the prognosis of teeth classified as “hopeless” should be regarded as a dynamic, case-dependent clinical judgment influenced by diagnostic accuracy, appropriate case selection, and contemporary regenerative approaches. The clinical relevance of maximizing tooth preservation prior to extraction and implant therapy is discussed.

The strategies for severe periodontitis ～hopeless to hopeful～
重度歯周炎罹患歯への挑戦 ～Hopeless to Hopeful～
- Periodontal regenerative therapy
- Microscope assisted surgery
- Furcation involvement
- Connective tissue grafting
- 歯周組織再生療法
- マイクロスコープ
- 根分岐部病変
- 結合組織移植
歯周組織再生療法は、失われたセメント質、歯根膜、歯槽骨を再建し、歯周炎罹患歯の予後を改善し得る治療法である。しかし炎症が進行するほど骨欠損は広範かつ深在化し、確実なデブライドメントは困難となる。さらに再生の基盤となる健全な歯根膜組織も減少し、治療難易度は上昇する。それでもなお、適切な診断のもと、マイクロスコープ下での強拡大視野による精密な感染除去、血餅安定化のためのスペースメインテナンス、必要に応じた自家組織移植を組み合わせることで、再生へ導くことは可能であると考える。本講演では、重度歯周炎罹患歯に対する再生療法症例を供覧し、術式の要点とその理論的背景について考察する。

Hopeless to Hopeful: The Potential of Monoblock Direct Composite Crown Restoration for Saving Root and Pulp
Hopeless to Hopeful：歯根・歯髄保存を目指したモノブロックダイレクトコンポジットクラウン修復の可能性
- A monoblock direct composite crown is a technique in which the coronal portion of a tooth is reconstructed with composite resin using a direct approach, even when the tooth is in a residual root condition.
- The advanced bonding protocol “SLDP” enables the realization of the monoblock direct composite crown technique.
- The monoblock direct composite crown helps restore the patient’s root structure, dental pulp, and ultimately, their smile.
- モノブロックダイレクトコンポジットクラウンは直接法で残根状態の歯からコンポジットレジンで歯冠を再建する方法
- モノブロックダイレクトコンポジットクラウンを叶えるためのアドバンスな接着処理SLDP

コンポジットレジン修復の適応は材料の進歩とともに拡大し、う蝕治療のみならず、様々な低侵襲なアプローチとして応用されている。
今回、過度なストレスと睡眠不足に伴う嘔吐を背景に、重度酸蝕症により全顎的な歯冠崩壊を呈し、笑顔を失った青年を報告する。
多くの歯で生活歯髄が維持されていたため、歯髄・歯根の保存を目的に前歯部へモノブロックダイレクトコンポジットクラウン修復を行い、臼歯部は補綴担当医によるセラミック修復を併用した。

Aesthetic Dentistry: small additions, big changes - the use of direct composite to enhance harmony and balance
- Smile parameters for maximum impact
- Layering strategies to augment and enhance natural tooth structure
- Key considerations in controlling optical results
- Smile parameters for maximum impact
- Layering strategies to augment and enhance natural tooth structure
- Key considerations in controlling optical results
Aesthetic dentistry is often associated with complex, invasive procedures, yet some of the most impactful smile transformations can be achieved through small, strategic additions. This lecture explores how direct composite resin can be used conservatively to enhance dental harmony, balance, and proportion while preserving natural tooth structure.
Through clinical case examples and step-by-step workflows, participants will learn how to identify aesthetic discrepancies related to tooth size, shape, symmetry, and spatial relationships, and how additive composite techniques can predictably address these concerns. Emphasis will be placed on diagnosis, smile design principles, material selection, layering strategies, finishing and polishing protocols, and long-term maintenance.
The session will also discuss patient selection, communication strategies, and the role of minimally invasive dentistry within contemporary aesthetic practice. Attendees will gain practical insights that can be immediately implemented in daily clinical workflows to deliver meaningful aesthetic improvements without aggressive preparation, improving patient confidence and satisfaction.

Achieving the "invisible" restoration in the anterior zone remains one of the ultimate challenges in restorative dentistry. For many clinicians, replicating the intricate interplay of color, opacity, and translucency found in natural teeth feels like a challenge. This lecture aims to "crack the code" of direct layering, transforming complex optical theories into a predictable clinical reality.
We will explore a simplified, evidence-based approach to emulate nature, moving beyond rigid recipes to a logical understanding of material behavior. By mastering the balance between chromatic dentin and translucent enamel, clinicians can master the technical steps that define natural-appearing restorations.
Attendees will navigate modern composite layering techniques, managing morphology and texture to achieve seamless integration. This session invites the next generation of dental leaders to embrace a workflow that blends scientific precision with artistic intuition for consistent, high-level aesthetic outcomes.

Let’s start with the Temporomandibular Joint and Finish with a Big Smile
Let’s start with the Temporomandibular Joint and Finish with a Big Smile
- Analyze and Apply Occlusal Principles: Identify the key components of a functional occlusion (such as centric relation and anterior guidance)
- Master the Sequencing Workflow: Develop a step-by-step protocol for complex cases, moving logically from biological stabilization to functional design and final esthetic execution.
- Integrate Form with Esthetics: Utilize "Facially Generated" treatment planning to determine ideal tooth position, ensuring that the restorative "Form" supports both facial harmony and function.
- Diagnostic Troubleshooting: Recognize "red flag" clinical signs—such as wear patterns or muscle pain—that require functional intervention before the esthetic phase begins.
- Communication & Case Acceptance: Enhance the use of diagnostic wax-ups and provisional restorations as "blueprints" to communicate expected outcomes clearly to both the patient and the laboratory.

In dentistry, the challenge often lies in knowing how to sequence a complex case from start to finish. Let’s make it simple and bring it all together by deconstructing TMJ anatomy and muscle physiology to understand how joint stability manifests in predictable restorative outcomes, and how we use the information to create smiles.
We will begin by learning how to use Splint Therapy not only as a treatment for Temporomandibular symptoms but as a vital diagnostic tool to find a stable, repeatable treatment position. By bridging the gap between appliance therapy, occlusal equilibration, and facially generated design, we will demonstrate a systematic workflow to restore Form, Function, and Esthetics with total predictability.
