目的:对比不同材料全瓷冠修复牙体缺损的临床效果。方法:选择2014年1月至2015年3月于台山市人民医院就诊的牙体缺损患者57例83颗患牙,通过二氧化锆全冠或氧化铝全冠的方式修复,均为单冠。修复后随访半年,观察修复体边缘密合性,修复体磨耗情况及继发龋坏等。结果:半年后复查时发现,两组各出现1例非A级病例,修复成功率分别是97.83%和97.30%。结论:在掌握全瓷冠修复适应证的前提下,合理选择不同材料的全瓷冠都可为前牙缺损甚至美学缺陷患者带来明显的临床效果改善。
Objective: To compare the clinical effects of all-ceramic crowns with different materials in the restoration of dental defects. Methods: From January 2014 to March 2015, 57 patients with dental defects treated in Taishan People’s Hospital were treated with zirconium crowns or alumina crowns. All of them were single crowns. Followed up for six months after repair, observe the edge of prosthesis adhesion, prosthetic wear and secondary caries and so on. Results: Six months after the review found that one case of non-A cases occurred in both groups, the repair success rates were 97.83% and 97.30%. CONCLUSION: All ceramic crowns with different materials can be used to improve the clinical effect of patients with anterior teeth defects or even aesthetic defects under the premise of mastering all ceramic crowns.
