摘要:

目的   评价并比较金合金嵌体、Ceramage聚合瓷嵌体、IPS EmpressⅡ铸瓷嵌体与复合树脂直接充填的修复效果。方法   选择138例患者189颗牙体缺损的磨牙,分别制作金合金嵌体45个、Ceramage聚合瓷嵌体48个、IPS EmpressⅡ铸瓷嵌体44个、复合树脂直接充填52个,应用美国公共健康协会的修正标准,每半年复查一次,评价修复效果。结果   3种嵌体在修复体颜色、边缘密合度、继发龋、食物嵌塞等指标上差异无统计学意义(P>0.05);在修复体完整性上铸瓷嵌体逊于金合金嵌体、聚合瓷嵌体(P<0.05);树脂充填的各项临床指标低于嵌体修复,在牙龈反应、食物嵌塞上差异有统计学意义(P<0.05)。结论   嵌体是较好的牙体缺损修复体,在恢复邻接关系和保持牙周健康等方面明显优于树脂充填。

Abstract:

Objective   To evaluate and compare the clinical performance of Au alloy inlays, IPS EmpressⅡceramic inlays, Ceramage inlays and resin restoration in restoring the molar defect. Methods   45 Au alloy inlays, 48 Ceramage inlays, 44 IPS EmpressⅡceramic inlays and 52 composite resin were used to restore 189 molars from 138 patients respectively. All restorations were evaluated after half a year according to modified USPHS parameters. Results   There was no significant difference in the color match, marginal sealability, secondary carries and food embed between the three groups (P>0.05). The Au alloy inlays and Ceramage inlays showed a significantly better performance in resisting fracture than the ceramic inlays (P<0.05). There was a significant difference in the gingival response and food embed between the resin fillings and the inlays (P<0.05). Conclusion   It is an intriguing method using inlays to restore the molar defect, which is superior to resin restoration in the aspects of restoring proximal relationship and maintaining periodontal health.
