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.

由于牙科疾病或创伤导致的牙齿缺失通常会导致相邻牙间乳头的缺失，这会导致美容问题、语音障碍和难以控制的牙菌斑。然而，在目前的牙科实践中，缺失的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嵴的种植体，用于牙间乳头的重建。本研究的目的是从组织学上评价新型植入物植入家兔顶骨时的有效性和安全性。在本研究中创建的所有三种类型的牙槽嵴种植体都导致了突起的形成，从而保持了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种植体在牙槽隔。
