Abstract: Abstract：Objective To evaluate the short-term aesthetic effect of immediate restoration of implant dentures in the maxillary anterior zone. Methods In Center of Implant Dentistry Affiliated Stomatological Hospital of China Medical University，select a total of 60 cases of denture implantation and reconstruction for the maxillary anterior teeth from January 2007 to January 2011，of which 30 cases with restoration half-year extension after implantation，30 cases with immediate restoration after implantation. After one-year follow-up，evaluate the aesthetic effect and satisfaction of the two groups of patients through the contour of gingival papilla，bone absorption，and satisfaction surveys. Results At a year，compared with the delayed restoration，the implant supported dentures with immediate restoration got good clinical results（P < 0.05）. It showed that less bone was absorbed around the immediate restoration than around the delayed restoration（P < 0.05）. The satisfaction rate of patients with immediate restoration was higher than that with the delayed restoration. Conclusion Immediate restoration is a better way to recover the contour of gingival papilla，with less bone absorption than the delayed restoration. Immediate restoration has better aesthetic effect.

摘要： 目的 评价上颌前牙区种植义齿即刻修复的短期美学效果。方法 选择中国医科大学附属口腔医院种植中心从2007年1月至2011年1月进行上颌前牙修复患者共60例，其中30例为种植后半年延期修复（延期修复组），30例为种植后当天即刻修复（即刻修复组），随访1年，通过牙龈乳头外形、骨吸收状况及满意度调查，评价两组患者的美学效果和满意度。结果 随访1年时，即刻修复组牙龈乳头外形明显好于延期修复组（P < 0.05）；即刻修复后骨吸收小于延期修复（P < 0.05）；即刻修复组患者满意率高于延期修复组。结论 在严格掌握适应证的前提下，即刻修复可很好地恢复美学区龈乳头外形，与延期修复相比骨吸收量较少，具有更佳的美学效果。
