摘要
目的探讨氧化锆个性化穿龈结构对薄龈生物型患者前牙区单牙种植修复后种植体周软硬组织稳定性的影响,以期为临床提供参考。方法回顾性纳入2018年1月至2022年12月于南方医科大学口腔医院牙周种植科进行前牙区单牙种植修复的20例薄龈生物型患者资料,其中男性9例,女性11例,年龄(35.2±10.3)岁。计算机辅助设计与辅助制作技术制作钛基底氧化锆个性化穿龈结构,该穿龈结构包括两种方式:钛基底氧化锆一体冠或个性化氧化锆基台+氧化锆外冠双层冠,以维持前牙美学区软组织穿龈轮廓。患者戴入最终修复体即刻和修复后3年复查,记录种植体存留率,采用粉色美学评分进行美学评估,根据数字化根尖片测量种植体边缘骨吸收量,用改良菌斑指数和改良出血指数评价牙周健康水平。结果修复后3年种植体存留率为100%(20/20),粉色美学评分为(9.3±0.9)分。修复后3年种植体近中和远中边缘骨吸收量分别为0.09(-0.21,0.20)和0.17(-0.12,0.27)mm,与修复后即刻(0)相比差异均无统计学意义(Z=-1.03,P=0.394;Z=-2.05,P=0.065)。结论氧化锆个性化穿龈结构能维持薄龈生物型患者前牙区种植体周软硬组织的稳定。
Objective To investigate the effect of zirconia personalized gingival structure on peri-implant soft and hard tissue stability after single-tooth implant restorations in patients with thin gingival biotypes in the anterior region,with a view to provide a clinical guideline.Methods This retrospective study included 20 patients with thin gingival biotype and implant restorations in the anterior region.These patients included 9 males and 11 females,and the age was(35.2±10.3)years.The patients were from the Department of Periodontal Implantology,Stomatology Hospital,Southern Medical University from January 2018 to December 2022.Computer-aided design/computer-aided manufacturing(CAD/CAM)techniques were used to fabricate a titanium base zirconia personalized gingival structure to maintain the soft-tissue perforated gingival contour of the anterior esthetic zone.This structure consists of two modalities:titanium base+zirconia outer crown or titanium base personalized zirconia abutment+zirconia outer crown.Clinical outcomes were recorded immediately and after delivery of the final restorations.Implant retention was recorded,esthetic scoring was performed using the pink esthetic index,the amount of bone resorption at the implant margins was measured based on digitized apical radiographs,and periodontal health was evaluated using the modified plaque index and the modified bleeding index.Results The survival rate of the 20 implants was 100%after 3 years of wearing the final restorations,with a pink aesthetic score of 9.3±0.9.Bone resorption at the proximal and distal mesial margins of the implants was 0.09(-0.21,0.20)mm,0.17(-0.12,0.27)mm after 3 years,respectively,and the difference was not statistically significant when compared to bone resorption immediately after placement of the final restoration[0(0,0)mm](Z=-1.03,P=0.394;Z=-2.05,P=0.065).Conclusions Zirconia personalized gingival structure maintains the stability of peri-implant hard and soft tissues of thin gingival biotypes in the anterior region.
