上颌前牙区种植义齿即刻修复短期美学效果评价

Clinical evaluation on short-term aesthetic effect of immediate restoration of implant dentures in the maxillary anterior zone

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。

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.
