Abstract
Objective:The aimed of this article was to use computer aided design/computer aided manufacturing(CAD/CAM)technique to fabricate an onlay crown for a crown-root fracture molar,and the clinical effect was observed.Methods:To ablate partial gingiva of the crown-root fracture molar which has completed root canal therapy using Nd:YAG laser until its subgingival margin was exposed.Then an onlay crown was fabricated using chair-side CAD/CAM technology to made onlay crown with lithium silicate.The clinical effect of the prosthesis was evaluated according to the United States Public Health Service(USPHS).Results:The margin,contact point,and occlusion relationship of the prosthesis were well,as well as the good gingival recover.There were no phenomena of fracture,loosening and loss occurred,and also no fracture,pain and loose found in the abutment with 2 weeks follow-up that the gingiva healed well.Conclusion:To fabricate an onlay crown for a crown-root fracture molar using CAD/CAM technique can obtain good clinical effects.关键词
