目的观察Cerec 3D制作的全瓷贴面修复前牙的临床效果。方法选择32例患者使用Cerec 3D共修复前牙全瓷贴面62例,所有修复体均经过上釉和外染色处理。以修复后1周复诊记录为基线,每6~12个月复查,由1位医师按照改良美国公共健康协会(USPHS)标准对修复体进行评价。结果 62例前牙修复体观察时间6~33个月,平均观察时间22个月。所有修复体的各项检查指标都达到了B类及以上,56例全瓷贴面修复体的各项指标均为A类,在观察期内未发现发生修复体脱落、破裂或继发龋。与基线对比,复查时没有发生明显的A类降为B类趋势。颜色匹配指标有6例修复体评为B类,主要表现为饱和度和半透明性上的差别。结论 Cerec全瓷贴面可以满足前牙修复美观和功能的需要,选择饱和度、半透明性正确的瓷块以及修复体适当的外染色均有助于前牙Cerec 3D全瓷贴面获得良好的美学效果。
Objective To observe the clinical effect of all-ceramic veneer made by Cerec 3D in repairing anterior teeth. Methods Thirty-two patients underwent cerec 3D repair of 62 cases of anterior teeth all-ceramic veneers, all of which were enamelled and stained externally. A follow-up visit was recorded as a baseline one week after repair, and was reviewed every 6-12 months. A physician evaluated the prosthesis according to the revised US Public Health Association (USPHS) criteria. Results 62 cases of anterior teeth prosthesis observation time of 6 to 33 months, the average observation time of 22 months. The indexes of all the prostheses reached Grade B and above. The indexes of 56 all-ceramic veneer prostheses were all Class A, and no detachment, rupture or secondary caries occurred during the observation period. Compared with the baseline, the review did not occur when the obvious type A to B trend. Color matching index of six cases of prosthesis as Class B, mainly for the difference between saturation and translucency. Conclusion The Cerec all-ceramic veneer can meet the aesthetic and functional requirements of the anterior teeth. The choice of saturation, translucent correct porcelain and appropriate external staining of the prosthesis all contribute to a good Aesthetic effect.
