摘要/Abstract

摘要： 目的评价高度为2 mm的矮愈合基台在前牙美学区早期种植中对唇侧骨增量保存的效果。方法选择2018年8月—2019年5月在青岛大学附属医院口腔种植科就诊,行前牙区早期种植+同期引导骨再生术（GBR）埋入式愈合的患者50例,实验组24例采用2 mm矮愈合基台,对照组26例使用封闭螺丝,术后随访18个月。比较术后6个月、18个月2组前牙区唇侧距种植体肩台0、3、6 mm水平骨量变化,术后18个月2组种植体存留率,粉色美学评分（PES）,改良龈沟探诊出血指数（mSBI）。采用SPSS 26.0软件包对实验数据进行统计学分析。结果术后6个月、18个月,实验组种植体唇侧肩台水平骨量变化较对照组低,在肩台处有统计学意义,其余位点均无统计学差异;术后18个月2组种植体留存率均为100%,实验组PES显著高于对照组（P<0.05）,2组mSBI无统计学差异（P>0.05）。结论矮愈合基台对前牙美学区唇侧水平骨量保存、软组织形态维持有明显效果,值得推广应用。

Abstract: PURPOSE: To evaluate the effect of 2 mm short healing abutment on incremental preservation of labial bone during early implantation in the aesthetic area of anterior teeth. METHODS: From August, 2018 to May, 2019, fifty patients were treated in the Department of Dental Implantation, Affiliated Hospital of Qingdao University. All patients in the experimental group were treated with 2 mm short healing abutment, while patients in the control group were treated with closed screws. The patients were followed up for 18 months. The changes of bone mass at the level of 0, 3 and 6 mm from the labial side of the anterior teeth area to the shoulder of the implant were compared between the two groups 6 and 18 months after operation, and implant retention rate, pink aesthetic score(PES) and improved gingival sulcus bleeding index (mSBI) were compared between the two groups 18 months after operation. SPSS 26.0 software package was used for statistical analysis of the data. RESULTS: After 6 months and 18 months, the changes of bone mass in the labial shoulder of the experimental group were significantly lower than those in the control group(P<0.05). There was no significant difference in other loci. Eighteen months after operation, the retention rate of implants in both groups was 100%. PES in the experimental group was significantly higher than that in the control group(P>0.05). There was no significant difference in mSBI between the two groups. CONCLUSIONS: Low healing abutment has obvious effect on preserving the labial bone mass and maintaining soft tissue morphology in the aesthetic area of anterior teeth, which is worthy of clinical promotion.
