摘要
目的探讨分别采用CAD/CAM全瓷嵌体与复合树脂嵌体对后牙Ⅱ类洞进行修复治疗的临床效果。方法选取后牙Ⅱ类洞患者165例作为研究对象,按照患者治疗意愿进行分组,分别为采用CAD/CAM全瓷嵌体修复治疗的A组83例,采用复合树脂嵌体修复治疗的B组82例,分析比较两组的修复效果。结果两组患者在修复体折裂与修复体脱落两个方面的成功率比较,差异无统计学意义(P>0.05);两组在修复体磨耗、边缘着色、边缘密合性及继发龋等方面的成功率比较,A组明显优于B组,差异具有统计学意义(P<0.05)。结论 CAD/CAM全瓷嵌体修复后牙Ⅱ类洞效果显著,与复合树脂嵌体修复效果比较修复成功率高,且可减少继发龋、修复体磨耗,边缘着色相对较少。
Objective To discuss the clinical effects of CAD/CAM all-ceramic inlay and composite resin inlay to repair class Ⅱ cavity of posterior teeth. Methods 165 patients suffering from class Ⅱ cavity of posterior teeth were selected as research objects and divided into two groups according to their willing. 83 cases of group A were provided with CAD/CAM all-ceramic inlay, while 82 cases of group B were offered with composite resin inlay. The effects of repair of two groups were compared and analyzed. Results The success rates of repairing teeth body fracture and teeth loss of two groups had no statistical difference （P 〉0.05）. The success rates of repairing degree of wearing, marginal coloring, marginal adaptation and secondary caries of group A were significantly higher than those of group B （P〈0.05）. Conclusions The effect of repairing class Ⅱ cavity of posterior teeth with CAD/CAM all-ceramic inlay is remarkable, higher than the effect of repair by composite resin inlay. Additionally, it can reduce secondary caries and degree of wearing, with relatively less marginal coloring.
