Resorption of the residual alveolar ridge often hinders ideal implant placement. In some cases, vertical bone loss causes the implant to be positioned more apically, resulting in aesthetic and biomechanical complications, as well as elongated clinical crowns as the outcome of treatment. This case presentation demonstrates a surgical technique that allows the use of distraction osteogenesis in combination with conventional orthodontic treatment to three-dimensionally reposition an implant-bony segment into a more favorable aesthetic and biomechanical position, thus improving the crown-to-implant ratio and leveling the gingival contours with those of the adjacent teeth.
残余牙槽嵴的吸收常常妨碍理想的种植体植入。在某些情况下，垂直骨量丧失会导致种植体位置更偏向根尖，从而引发美学和生物力学方面的并发症，以及治疗后临床冠延长的问题。本病例展示了一种手术技术，该技术允许在常规正畸治疗的同时结合牵张成骨，将种植体 - 骨段三维重新定位到更有利的美学和生物力学位置，从而改善冠根比，并使牙龈轮廓与相邻牙齿的牙龈轮廓平齐。
