摘要
目的研究个性化铸瓷复合基台改善前牙区软、硬组织缺损的种植美学效果,以期为临床治疗提供一定的参考.方法选择2011年10月～2013年10月入院诊治的前牙区种植美学欠缺的患者60例.术前均对患者进行口腔内检查,并应用X线、锥形束CT对患者的牙齿情况进行测量后,根据患者的情况制订个体化基台,并铸造相应的全瓷外冠,用以改善牙颈部“透黑”现象.在种植改善后随访3～6个月,以健康的邻牙或侧牙为标准,对患者进行美学评价.结果60例患者共67枚种植体,其中47例（47枚）为单冠,13例（20枚）为固定桥和联冠;WES各项评分最高为（1.76±0.42）分,最低为（1.38±0.50）分,提示患者种植体的白色美学较好,PES各项评分最高为（1.92±0.29）分,最低为（1.45±0.49）分,提示患者种植体的红色美学较好;Jemt牙龈乳头指数：Ⅳ度与0度均为0,Ⅲ度占38.33％,Ⅱ度占56.67％,Ⅰ度占5.00％.结论个性化铸瓷复合基台可有效改善前牙区的种植美学与契合程度.
Objective To research the implant esthetics effect of personalized casting porcelain composite base station improving soft and hard tissues＇ defect of anterior teeth area for providing reference for clinical treatment. Methods 60 cases with implant esthetics defect of anterior teeth area treated in our hospital from October 2011 to October 2013 wereselected.The patients received intraoral examination before operation.,the teeth of patients were measured by X ray and cone-beam CT,personalized base station was formulated according to patients＇ condition,and corresponding all-ceramic crown were casted to improve ＂blackness＂ of dental neck.After implant improve,patients were followed-up for 3- 6 months,the healthy adjacent teeth or lateral teeth were used as the standard to make aesthetic evaluation on patients. Results There were 67 implants in 60 cases,in which 47 cases （47） were single crowns,and 13 cases were fixed bridges and combined crowns.For WES scores of 60 cases,the highest score was （1.76±0.42） points,and the lowest was （1.38± 0.50）,which indicated that white aesthetics of implants was better,and for PES,the highest score was （1.92±0.29） points, and the lowest was （1.45±0.49）,which indicated that red aesthetics of implants was better;papilla index of Jemt gingival： Ⅳ and 0 degree were O, Ⅲ degree was 38.33%, Ⅱ degree was 56.67% and Ⅰ degree was 5.00%. Conclusion personalized casting porcelain composite base station can effectively improve implant esthetics and combination degree of anterior teeth area.
