上颌前牙单牙即刻非功能性负重种植的临床研究

目的探讨上颌前牙美观区单牙即刻非功能性负重人工牙种植的临床效果。方法对26例26颗上颌前牙种植者，在置入种植体的同时，接入临时基台行复合树脂暂时冠临时修复，2～6个月后，更换永久性烤瓷冠修复体。结果种植体置入后，随访12-72个月，没有种植体丢失。前12个月平均边缘骨丧失为0．78mm，随访期内，累积平均骨丧失为1．17mm。结论严格掌握适应证，上颌前牙单牙即刻非功能负重种植，能满足患者临时的美观需求，临床效果良好。

Single-tooth replacement in the aesthetic zone of maxilla with immediate provisionalization: a clinical study

Objective To investigate the clinical results of immediate loading of a single anterior implant. Methods 26 implants were placed into anterior sites. Provisional prosthesis were placed at the time of fixture placement. It did not occlude in any pathway. Restoration was for esthetic only, not for function. Results No fixture was lost since the immediate restoration was delivered, the minimum being 12 months and the maximum 72 months.
