The aim of this article is to make a comparative assessment between the modification of the soft-tissue profile, around the healing cap screws (HCSs), following both the traditional flapless surgery (TFS) and a new modified flapless surgery, named Modified Connective Tissue Punch (MCTP) technique.
8 patients (3M and 5F) (mean age 54.25±11.247 years) were enrolled in this study. Sixteen two-piece implants were placed on upper jaws, 2 for each patient, 8 with TFS and 8 with MCTP technique. In each patient the implants were placed in edentulous areas, of 2 or 3 adjacent teeth long. MCTP technique was performed on the front implant site (FIS) while the TFS was performed on the rear implant site (RIS). All implants were inserted and covered with healing cap screws (HCSs). Alginate impressions were carried out at the moment of the surgery, at 1 month and 4 months post-operative. Plaster models were poured and subsequently digitally scanned, in order to measure the distance between the gingival outline and the free margin of the HCS. The recorded values were analyzed with the ANOVA test.
The use of MTCP technique, in comparison to TFS, showed a significative better outcome, in terms of vertical increments, of gingiva, on the VS toward the HCSs, during the entire observation period (p = 0.000 for all).
The Authors recommend the use of MCTP technique for a better vestibular soft tissue outcome in flapless implant surgery.
本文旨在对传统无瓣手术（TFS）和一种名为改良结缔组织冲孔（MCTP）技术的新型改良无瓣手术后，愈合帽螺钉（HCS）周围软组织轮廓的改变进行比较评估。
本研究纳入8例患者（3例男性和5例女性）（平均年龄54.25±11.247岁）。在上颌植入16枚两件式种植体，每位患者植入2枚，其中8枚采用TFS技术，8枚采用MCTP技术。在每位患者中，种植体植入无牙区，长度为2或3颗相邻牙齿。MCTP技术应用于前部种植位点（FIS），而TFS应用于后部种植位点（RIS）。所有种植体均植入并覆盖愈合帽螺钉（HCS）。在手术时、术后1个月和4个月进行藻酸盐印模。灌注石膏模型并随后进行数字扫描，以测量牙龈轮廓与HCS自由边缘之间的距离。记录的值采用方差分析进行分析。
在整个观察期内，与TFS相比，MTCP技术在朝向HCS的VS上，牙龈垂直增量方面显示出显著更好的结果（所有p = 0.000）。
作者推荐在无瓣种植手术中使用MCTP技术以获得更好的前庭软组织结果。
