摘　　要：目的:探讨生物导向型预备技术及其修复工艺流程用于残冠修复的优越性。诊治经过:选取上前牙残冠修复病例1例,采用生物导向型预备技术对残冠进行牙体预备,通过人工牙龈记录牙龈形态,制作带有光滑氧化锆穿龈颈圈的牙冠修复体在患者口内完成佩戴。结果:牙冠就位良好,边缘密合,色泽逼真。修复后3个月、6个月复查,牙龈位置稳定,牙周组织健康,获得了较好的美学修复效果。结论:使用生物导向型预备技术配合良好的牙冠加工工艺能使残冠获得良好的临床修复效果。Objective:This study aims to investigate the advantages of biologically oriented preparation technique and its processing technique in the restoration of residual crown.Diagnosis and treatment:In a case about restoration of residual crown in upper anterior tooth,the tooth preparation was conducted by using biologically oriented preparation technique.A dental crown with a smooth zirconia neck was processed by improved crown processing technique which recorded gingival profile through artificial gingiva.And this final restoration was placed in the patient’s mouth.Results:The final crown restoration had good margin fit and realistic color.Follow-up at 3 and 6 months after treatment respectively,the position of gingiva was stable and the periodontal tissue was healthy.The residual crown of the upper anterior tooth was successfully restored with aesthetically pleasing and stable outcome.Conclusions:The combination of biologically oriented preparation technique and high-quality crown processing technique can lead to favorable clinical restoration outcomes of residual crowns.
