摘　　要：背景:随着患者不断提升的美观要求,不管是前牙还是后牙修复,有一定强度且美观的基台材料越发引起人们的关注。目的:评价前牙区钛基台与氧化锆基台修复对种植体周围组织的影响。方法:选择行前牙区种植修复患者34例(40颗牙齿),植入Ankylos系统种植体并完成单冠修复,其中20颗采用钛基台,另20颗采用氧化锆基台,冠修复后12个月复诊,通过影像学评价种植体周围骨吸收量,同时检测牙周探诊深度、改良菌斑指数、改良龈沟出血指数及龈乳头指数,调查患者对种植修复的满意度,并应用红色美学评分标准进行美学评价。结果与结论:钛基台修复组与氧化锆基台修复组牙周探诊深度、改良菌斑指数、改良龈沟出血指数、龈乳头指数比较差异无显著性意义;两组修复后12个月的种植体周围骨吸收量无差异;两组患者对种植修复的满意度均较高,组间比较无差异;氧化锆基台修复组的红色美学评分高于钛基台修复组(P<0.05)。结果表明,钛基台与氧化锆基台修复对种植体周围软硬组织的影响无差异,均能获得较好的临床修复效果,但氧化锆基台在前牙区美学修复存在一定优势,长期效果有待于进一步观察。BACKGROUND:With the increasing aesthetic pursuit of patients,an aesthetic abutment with certain strength has aroused people’s attentions either in the anterior or posterior tooth repair.OBJECTIVE:To evaluate the effects of titanium abutment and zirconia abutment on peri-implant tissue in anterior teeth.METHODS:A total of40anterior teeth from34patients were selected and received single crown restoration with Ankylos implants.Among them,titanium abutments were used in20teeth,and zirconia abutments in the other20teeth.All the patients were re-visited at12months after crown restoration.Peri-implant marginal bone resorption length(MBL),periodontal probing depth(PD),modified plaque index(mPLI),modified sulcus bleeding index(mSBI),and papilla index(PP)were detected;patient satisfaction investigation was carried out;and aesthetic assessment was done based on the pink esthetic score(PES).RESULTS AND CONCLUSION:There were no differences between two groups in MBL,PD,mPLI,mSBI,PP.Patients in both groups were satisfied with the treatment outcomes with insignificant difference(P>0.05).The PES value in the zirconia abutment group was significantly higher than that in the titanium abutment group(P<0.05).Overall,titanium and zirconia abutments show the similar effects on the peri-implant tissues and both can achieve good clinical outcomes.However,zirconia abutments have certain advantages in the aesthetic restoration for anterior teeth,and further investigation on long-term effects is warranted.
