Replacing small, single incisors with implants can be esthetically challenging and difficult because of the limited amount of bone. In this investigation, 3.0-mm-diameter implants were used to support 30 single maxillary and mandibular incisors in 21 patients. The implants have been in function for 3 to 7 years, and 29 are still stable. Only 2 complications in the mandibular incisor region have occurred; 1 implant fractured (after 5 years of function) and 1 prosthesis was replaced. The overall success rate is 96.7%. The favorable results and esthetic appearance achieved suggest that replacing small incisors where light occlusal forces are present with narrower implants is a feasible treatment option.
由于骨量有限，用种植体替代单个小切牙在美学上具有挑战性且难度较大。在本研究中，使用直径3.0毫米的种植体为21例患者的30颗上颌和下颌单颗切牙提供支持。这些种植体已使用3至7年，29颗仍保持稳定。仅在下颌切牙区域发生了2例并发症；1颗种植体断裂（使用5年后），1个修复体被更换。总体成功率为96.7%。所取得的良好效果和美观外观表明，对于存在轻度咬合力的小切牙，用较窄的种植体进行替代是一种可行的治疗选择。
