摘要
目的:探讨不同修复方式用于后牙楔状缺损的疗效。方法:选取诊治的后牙楔状缺损患者90例,将患者随机分为三组:A组30例(34颗牙)、B组30例(35颗牙),C组30例(37颗牙)。A组:给予复合树脂进行修复治疗;B组:给予金属桩核+金属烤瓷冠进行修复治疗;C组:给予氧化锆桩核+氧化锆烤冠修复治疗。观察患者修复后1年时的患牙咀嚼功能满意度、颜色匹配满意度、牙龈边缘着色满意度、牙龈出血指数、牙周袋深度、附着丧失及并发症发生情况,进行疗效评价。结果:对三组患者修复后咀嚼功能满意度、颜色匹配满意度及牙龈边缘着色满意度比较,差异有统计学意义(P<0.001);三组患者修复后患牙牙龈指数、牙菌斑指数及牙周附着水平比较,差异无统计学意义(P=0.856);三组患者患牙修复后继发龋发生率比较,差异有统计学意义(P=0.032),桩核折断或核冠损坏发生率B组高于C组(P=0.039),牙龈炎发生率比较差异有统计学意义(P=0.030);三组患者患牙修复成功率比较差异有统计学意义(P=0.021)。结论:复合树脂、金属桩核+金属烤瓷冠、氧化锆桩核+氧化锆烤冠修复后牙楔状缺损,均可达到良好治疗目的,但是修复后美学效果及咀嚼功能氧化锆桩核+氧化锆烤冠修复优于其他两种修复方式,复合树脂修复后继发龋发生风险性相对高,牙龈炎、桩核折断或核冠损坏发生风险性则金属桩核+金属烤瓷冠相对较高。
Objective To investigate the research of different repair methods for wedge-shaped defect of posterior teeth.Methods We selected 90 cases of patients with wedge-shaped defect of posterior teeth,the patients were randomly divided into three groups:30 patients in group A(34 teeth),30 patients in group B(35 teeth),and 30 patients in group C(37 teeth).The group A was treated with composite resin,group B was treated with metal post core+ceramic crown,and group C was treated with zirconia post core+zirconia crown.We observed satisfaction degree of chewing function,color matching,gingival edge coloring,gingival bleeding index,depth of periodontal pocket,loss of attachment and occurrence of complications of patients in 1 year after repair,to evaluate the effi cacy.Results The satisfaction degree of chewing function,color matching,gingival edge coloring,the difference between the three groups was statistically signifi cant(P<0.001).The gingival bleeding index,depth of periodontal pocket,loss of attachment,the difference between the three groups was no statistically signifi cant(P=0.856).The incidence of secondary caries after dental restoration was statistically significant between the three groups(accurate probability=0.032),the incidence of post-core fracture or crown damage in group B was higher than that in group C(accurate probability=0.039).The difference of gingivitis incidence was statistically signifi cant(accurate probability=0.030).There was a statistically signifi cant difference in the success rate of tooth restoration among the three groups(accurate probability=0.021).Conclusion The composite resin,metal post core+metal ceramic crown,zirconia post core+zirconia crown were used to repair the wedge-shaped defect of posterior teeth,there were can achieve good therapeutic purpose,the aesthetic effect and chewing function of zirconia post core+zirconia crown after treatment are superior to the other two restoration methods,the risk of secondary caries after composite resin repair is relatively high,risk of gingiv
