腭侧结缔组织瓣唇向卷入技术应用于种植前牙软组织增量的临床研究

Clinical study of palatal roll connective tissue flap applied to soft tissue increments in implant resto-ration in the anterior zone

摘要目的采用腭侧结缔组织瓣唇向卷入技术来增加前牙区局部软组织量，对美学效果加以对照评价。方法选择18例前牙区种植患者（20个种植体）二期手术时同期行腭侧结缔组织瓣唇向卷入术作为观察组。另选前牙区种植患者15例（16个种植体）仅接受常规种植二期手术为对照组。在种植二期手术前、手术后1个月、手术后6个月，对两组患者种植位点唇侧丰满度和种植位点红色美学指数（PES）进行评分，并加以分析。结果种植二期术后6个月时，观察组唇侧丰满度评分明显高于术前和对照组（P〈0．05）；观察组二期术后1个月和6个月的时候PES评分均高于术前和对照组（P〈0．05）。结论腭侧结缔组织瓣唇向卷入能明显提高种植位点的红色美学效果，且具有较好的稳定性，适合在临床上加以推广应用。

Objective To evaluate the aesthetic effect of palatal roll connective tissue flap applied to soft tissue increments in implant restoration in the anterior zone. Methods Eighteen patients treated an- terior implant restoration （20 implants） underwent palatal roll connective tissue flap, at the same time when the gingival healing cap was placed. Fifteen patients treated anterior implant restoration （16 implants） un- derwent conventional second-stage surgery as a control. We recorded the score of lip soft tissue fullness and pink esthetic score （PES） at the follow time points ： before second-stage surgery; 1 month and 6 months af- ter second-stage surgery. Results The score of lip soft tissue fullness in the observation group were signifi- cantly higher than those in the preoperative and control groups at 6-month follow-up （P 〈 0.05 ）. The PES in the observation group was significantly higher than that in the preoperative and control groups at 1-month and 6-month follow-up （ P 〈 0. 05 ）. Conclusions The palatal roll connective tissue flap can significantly improve the red aesthetics of the implant restoration and has good stability.
