即刻种植利用愈合基台封闭创口并保持牙龈形态的临床初探

目的 探讨即刻种植中利用愈合基台封闭伤口并保持牙龈自然形态的技术要点,并评估初期临床效果.方法 31例患者在无创拔牙后即刻植入种植体并用Bio-Oss植骨,同时安装愈合基台,3个月后行烤瓷冠修复,修复后平均追踪观察9个月.结果 除1颗种植体于植入后2周脱落外,其余种植体骨结合良好,牙龈原始形态基本完整保存.修复后至修复后3～16个月复查,临床效果满意.结论 在单牙即刻种植中利用愈合基台封闭创口并保持牙龈自然形态的临床方法安全简便,修复美学效果好.

Clinical study of healing abutment on sealing socket and preservation of the gingival natural profile in single-tooth immediate implantation

Objective To investigate the clinical results of use of healing abutment for sealing socket and preserving the gingival natural profile in single-tooth immediate implantation.Methods The osteotomy site was prepared with pilot drill directed by the periodontal probe on palatal wall of the socket,and 31 single-implant were placed into fresh sockets with Sapless surgery and filled with Bio-oss.Healing abutments were simultaneously fitted on implants and ceramic crowns fabricated three months post-operation.Scientific assessment of soft tissue contour Was carried out by interdental papillae index immediately after restorations.Results One implant was lost at second week after operation.The remaining 30 implants gained perfect osseointergration and the gingival natural profile was preserved completely.Conclusions Sealing socket and preserving the gingival natural profile by healing abutment is a predictable,safe and practical method with good aesthetic results in single-tooth immediate implantation.
