摘　　要：目的　评价两种不同材料修复变色牙的临床美容效果及远期保存率。方法　采用赛美美容瓷 (cerinateporcelain ,CE)或釉质瓷 (belleglassHP ,BGHP)对 647例变色牙患者的 1871颗牙齿进行美容修复 ,并作了近期 (0 .5～ 1年 )和远期 (3年以上 )临床追踪观察及效果评价。结果　BGHP组和CE组的近期有效率分别为 89.65%和 96.57% ,远期有效率分别为 88.3 9%和 96.14 % ,两组比较差异有显著性意义 (P <0 .0 0 5) ;而同一种材料的近、远期修复效果差异无显著性意义 (P >0 .0 0 5) ;失败发生率与患牙类型、牙位、修复类型、材料等因素有关 ,主要表现为修复体变色、折裂、脱落等。结论　BGHP修复变色牙 ,抗折力强 ,具有较高的远期保存率 ,但美观效果需进一步探讨 ;CE类修复具有美观效果好、远期保存率高的优势 。ObjectiveTo evaluate the esthetic and long-term effec ti veness of Cerinate porcelain(CE) and Belleglass HP (BGHP) in restoring discolore d teeth. MethodsA total of 1871 discolored teeth from 647 pat ients were restored using two materials. The observation of short-term(0.5 to l year) and long-term (over 3 years) effectiveness were followed up, and evaluat ions were made. ResultsThe short-term successful rates were 8 9.5 % and 96.75 % for BGHP CE groups, the long-term successful rates were 88.3 9 % and 96.14 %, and the difference was statistically significant (P<0.005) . But no significance was found between long-and short-term sucessful rates of either material (P>0.005). Clinical failure, which was mainly related to t eeth category, teeth position, type of restoration and material, showed as resto ration discoloration, fracture and deciduous, etc. Conclusion BGHP shows higher shear bond strength and longer existence, but further study is required for esthetic results. CE restorations show better esthetic results and longer existence. Therefore, it is an ideal choice to restore discolored teeth.
