| Outline of Final Research Achievements |
In dental implant treatment, maintaining the inter-implant bone is essential to ensure aesthetics. Conical connection implants, which are mechanically useful for maintaining it, are often combined with zirconia abutments from an aesthetic standpoint. Model experiments were conducted to evaluate the mechanical effects of differences in design, and the results showed that while a titanium base improved the fracture resistance of the abutment, it caused a lot of deformation in the implant components. Furthermore, in the group with a narrow implant body diameter, the one-piece zirconia type showed significantly less deformation. These results suggest that it is necessary to consider not only the abutment connection style but also the mechanical properties of the abutment.

本研究において，インプラント間歯槽骨の維持に力学的に最適なアバットメント連結様式はコニカルコネクションタイプであり，審美性の観点からジルコニアアバットメントと組み合わせることが多い．ワンピースジルコニアタイプとチタンベース付きジルコニアタイプの2種類があり，その違いがインプラント構成要素に及ぼす力学的影響を評価するため模型実験を行った. その結果，アバットメントの設計や材質だけでなく直径の差異もインプラント構成要素に様々な力学的影響を及ぼすことが解明された．隣接する2本のインプラントを埋入する際の，インプラントやアバットメントのデザインの選択に重要な示唆を与えたことになると考えられる.
