上颌前牙种植体周围牙龈乳头重建的临床研究

The Clinic Study of Reconstruction of the Gingival Papilla Surround Dental Implant in the anterior maxilla

目的:寻找上颌前牙种植的牙龈乳头重建的方法。方法:选择30例上颌前牙种植二期术患者随机分实验与对照组,实验组上颌前牙种植区正中偏腭侧作横切口,并保留龈乳头,钝性剥离颊腭侧龈组织瓣及龈乳头瓣,以基台弧度为模板,制备适当宽度有蒂龈组织瓣,并旋转植入近远中龈乳头瓣下方,基台挤压龈乳头瓣诱导种植体周围龈乳头成形;上部结构(基台)精细研磨,重建无缝隙冠龈连接,精度贵金属烤瓷修复。对照组上颌前牙种植区正中切口,剥离粘骨膜瓣,上愈合基台,常规牙龈缝合;基台研磨贵金属烤瓷修复.分别于种植修复后3、6、12月测量上颌前牙种植周龈乳头高度.和评价龈乳头外形。结果:实验组龈乳头恢复明显好于对照组(p<0.01),龈乳头外形明显优于对照组(p<0.01)。结论:上颌前牙种植的龈乳头重建方法简单,可行。

Objective：To find the method of new gingival papilla surround dental implant in the anterior maxilla. Methods： A randomized controlled experiment was conducted. 30 adult patients without teeth in the anterior maxilla were divided into two groups, experimented groups and controlled groups. Experimented groups were gone soft tissue management surround implant, mental focus porcelain restorations. Patients of controlled groups were gone standard second stage surgery, final mental focus porcelain restorations. Esthetic results were observed 3,6,12 months after dental implant prosthetics. Results： The quality of new gingival papilla surround implant in the anterior are more than the controlled （p〈 0.01 ）; The gingival papilla outcome surround implant are much more satisfied than the ones （p〈0.01）. Conclusion： The methods of new gingival papilla surround implant in the anterior maxilla are predictable.
