目的:探讨二氧化锆全瓷冠的临床修复效果。方法:选择68例患者共88颗二氧化锆修复的全瓷单冠进行随访,参照美国公共健康协会修订的标准进行评估。结果:88颗二氧化锆全瓷冠在牙龈健康、颜色、继发龋、边缘适合性等方面表现优良,有5例6个二氧化锆瓷冠出现饰瓷的崩瓷或裂纹,1个牙因根折而拔除。结论:二氧化锆全瓷冠具有良好的临床修复效果,但饰瓷有折裂的风险。
Objective: To investigate the clinical effect of zirconia all-ceramic crowns. METHODS: A total of 88 zirconium oxide-restored all-ceramic single crowns of 68 patients were followed up and evaluated according to the revised standards of the American Public Health Association. Results: All 88 zirconia ceramic crowns performed well in terms of gum health, color, secondary caries, edge suitability, etc. There were 5 cases of 6 zirconia porcelain crowns showing porcelain collapse or cracks and 1 tooth Remove due to root fold. Conclusion: Zirconia all-ceramic crown has a good clinical repair effect, but the porcelain has the risk of fracture.
