目的探讨铸造金属全冠修复老年人活髓磨牙临床短冠的疗效。方法对临床牙冠高度低于3mm的老年人活髓磨牙采用铸造钴铬合金全冠修复,分别戴用6个月、1年、2年后评价其形态、牙髓活力、基牙继发龋齿、修复体边缘密合度、修复体磨耗及脱落情况。结果57件全冠修复体有3件脱落,2件出现继发龋齿,半年成功率为100.0%,1年成功率为95.2%,2年成功率为88.1%。结论钴铬合金铸造全冠对于老年人活髓磨牙临床短冠的修复效果好,临床可以推
Objective To investigate the curative effect of cast metal crown on the clinical short crown of live pulp in elderly patients. Methods The aged patients with clinical crown less than 3mm were treated with cast-in-place cobalt-chromium alloy crown, and were respectively worn for 6 months, 1 year and 2 years. The morphology, endodontic activity, secondary tooth decay , The edge of the prosthesis adhesion, repair wear and tear off the situation. Results There were 3 cases of 57 full crown prostheses, 2 cases of secondary caries. The half-year success rate was 100.0%. The success rate was 95.2% at 1 year and 88.1% at 2 years. Conclusion Cobalt-chromium alloy casting crown for elderly patients with live molars clinical short crown repair effect is good, the clinical can push
