摘要:

背景:二氧化锆全瓷冠修复以其优良的机械性能、生物相容性和美学性能在临床上受到欢迎和认可。

目的:比较采用计算机辅助设计与计算机辅助及传统方法制作二氧化锆全瓷冠修复的临床效果。

方法:纳入进行口腔全瓷冠修复患者87例,其中男56例,女31例,年龄21-56岁,其中42例采用计算机辅助设计与计算机辅助制作的二氧化锆全瓷冠进行修复,作为试验组;另45例采用传统方法制作的二氧化锆全瓷冠进行修复,作为对照组。修复6个月时,对比两组修复体表面质地、颜色匹配、解剖外形、边缘适合性、牙龈健康及患者满意度调查结果。

结果与结论:试验组患者对修复后全瓷冠形态颜色的满意率达到100%,总体满意率达95%,显著好于对照组形态颜色满意率的78%及总体满意率的82%(P < 0.05)。试验组在修复体外形方面优于对照组(P < 0.05),两组在修复体表面质地、颜色匹配、边缘适合性方面比较差异无显著性意义(P > 0.05)。两组全瓷冠均无变色、崩瓷、裂纹及其他不良反应。说明通过计算机辅助设计与计算机辅助制作技术完成的氧化锆全瓷冠具有良好的美学效果、稳定性及生物相容性。

Abstract:

BACKGROUND: Zirconia all-ceramic crowns have been widely accepted in the clinic because of its excellent mechanical properties, biocompatibility and aesthetic performance.

OBJECTIVE: To investigate the clinical efficacy of zirconia all-ceramic crowns prepared using computer-aided design/computer-aided manufacturing versus conventional method.

METHODS: Eighty-seven patients who used zirconia all-ceramic crowns, consisting of 56 males and 31 females, aged 21-56 years were included in this study. Among these patients, 42 patients were subjected to tooth repair with zirconia all-ceramic crowns prepared using computer-aided design/computer-aided manufacturing technique (experimental group) and 45 patients received tooth repair with zirconia all-ceramic crowns prepared using conventional method (control group). At the end of the 6th month after zirconia all-ceramic crown repair, denture surface texture, the color of the restoration, anatomic appearance of prosthesis, marginal integrity, denture health and patient’s satisfaction were investigated between the experimental and control groups.

RESULTS AND CONCLUSION: After repair with zirconia all-ceramic crowns, patient satisfaction rate of the color of the restoration and total patient satisfaction rate in the experimental group were significantly greater than in the control group (100% vs. 78%, 95% vs. 82%, P < 0.05). The anatomic appearance of prosthesis in the experimental group was superior to that in the control group (P < 0.05). There were no significant differences in

 

denture surface texture, the color of the restoration, and marginal integrity between the experimental and control groups (P > 0.05). Discoloration, cracks and chipping and other adverse reactions were observed in neither experimental group nor control group. These findings suggest that the zirconia all-ceramic crowns prepared using computer-aided design/computer-aided manufacturing technique exhibit good aesthetic performance, stability and biocompatibility.
