Development of crestal implant for interdental papilla reconstruction

由于牙齿疾病或外伤导致的牙齿脱落通常会导致邻近的牙间乳头的脱落，从而导致美容问题、语音障碍和难以控制牙菌斑。然而，在目前的牙科实践中，牙间乳头的重建是非常困难的。因此，我们设计了一种基于牙槽间嵴的牙冠种植体用于牙间乳头重建。本研究的目的是组织学评价新型种植体植入兔顶骨的有效性和安全性。本研究中创建的所有三种冠种植体都能形成突起，从而保持种植体与周围组织的整合。我们的研究结果表明，牙间乳头重建是可能的放置种植体在牙槽间间隔。

The loss of teeth due to dental disease or trauma often causes loss of the adjacent interdental papillae, which leads to cosmetic problems, phonetic disturbances, and difficult plaque control. However, reconstruction of lost interdental papillae is very difficult in current dental practice. Therefore, we designed a crestal implant based on the interalveolar crest for interdental papilla reconstruction. The purpose of this study was to histologically evaluate the efficacy and safety of the novel implant when implanted in rabbit parietal bone. All three types of crestal implants created in this study led to the formation of projections, which maintained the integration of the implant with the surrounding tissue. Our findings suggest that interdental papilla reconstruction is possible by placing implants in the interalveolar septa.
