Surgical incision designs are considered closely correlated to gingival papilla of dental implants. This study aims to explore whether different incision techniques for implant placement and second stage surgery affect gingival papilla height.
Cases using different incision techniques (intrasulcular incisions or papilla sparing incisions) between November 2017 and December 2020 were selected and analyzed. A digital camera was used to capture images of gingival papilla at different time points. Ratio of papilla height to crown length using different incision techniques were measured and statistically compared.
A total of 115 papillae (68 patients) were eligible according to the inclusion/exclusion criteria. The average age was 39.6 years. Decreased postoperative papilla height were observed after implant placement surgery in all groups without statistical difference. However, for second stage surgery, intrasulcular incisions lead to more atrophy in gingival papilla compared to papilla sparing incisions.
Selection of incision techniques in implant placement surgery does not significantly affect papilla height. For second stage surgery, intrasulcular incisions significantly leads to more papilla atrophy compared with papilla sparing incisions. Trial registration KQCL2017003.
外科切口设计被认为与牙种植体的牙龈乳头密切相关。本研究旨在探讨种植体植入和二期手术中不同的切口技术是否会影响牙龈乳头高度。
选择 2017 年 11 月至 2020 年 12 月期间使用不同切口技术（内切口或保留牙龈乳头切口）的病例进行分析。使用数码相机在不同时间点拍摄牙龈乳头的图像。测量并比较使用不同切口技术的牙龈乳头高度与牙冠长度的比值。
根据纳入/排除标准，共有 115 个牙龈乳头（68 例患者）符合条件。平均年龄为 39.6 岁。所有组在种植体植入手术后，牙龈乳头的术后高度均有下降，但无统计学差异。然而，对于二期手术，与保留牙龈乳头切口相比，内切口导致牙龈乳头萎缩更为明显。
种植体植入手术中切口技术的选择不会显著影响牙龈乳头高度。对于二期手术，与保留牙龈乳头切口相比，内切口明显导致更多的牙龈乳头萎缩。试验注册号 KQCL2017003。
