This study describes a clinical case in which a primary maxillary canine with both mobility and root resorption was replaced with an immediately restored dental implant placed into the fresh extraction socket. The implant achieved high primary stability, as determined by resonance frequency analysis, and it was immediately restored with a provisional acrylic resin crown with no centric occlusion. An all-ceramic permanent crown replaced the provisonal crown four months after implant surgery. The implant was stable and no periapical radiolucencies, bleeding on probing, or pathologic probing depth were recorded after one year. The peri-implant soft tissue level appeared stable, and the interdental papillae were preserved, contributing to an optimum final esthetic result. This case supports the use of single implants for the replacement of extracted primary teeth, especially in areas where esthetics is a high priority. The immediate provisional crown maintained soft tissue contours and papillary height.
本研究描述了一个临床病例，其中一颗具有松动和牙根吸收的上颌乳尖牙被替换为植入新鲜拔牙窝并立即进行修复的牙种植体。通过共振频率分析确定，该种植体获得了较高的初期稳定性，并立即用无正中咬合的临时丙烯酸树脂冠进行修复。种植手术后四个月，全瓷永久冠替换了临时冠。一年后，种植体稳定，未记录到根尖周透射影、探诊出血或病理性探诊深度。种植体周围软组织水平保持稳定，牙间乳头得以保留，有助于获得最佳的最终美学效果。该病例支持使用单颗种植体替换拔除的乳牙，尤其是在美学要求较高的区域。即刻临时冠维持了软组织轮廓和乳头高度。
