摘　　要：目的：探讨铸造纯钛分体桩核冠修复低（牙合）龈距离磨牙的效果.方法：对22例患者的低（牙合）龈距离磨牙残根及残冠行铸造纯钛分体桩核冠修复.沿磨牙根管方向进行桩核预备,按临床修复常规完成基牙牙体预备,用注射型硅橡胶印模材取印模,制作纯钛分体桩核冠,用树脂水门汀对修复体进行粘结,完成修复.结果：随访6～30个月,22例患者的22个修复体均固位良好,未出现修复体松动、脱落或牙根折裂,均能正常行使功能.结论：铸造纯钛分体桩核冠修复低（牙合）龈距离磨牙残根及残冠,可以取得较好的临床效果.PURPOSE： To evaluate the clinical effect of custom casting separate post-and-core crown restorations of titanium in residual molar roots and crows with low occlusogingival distance. METHODS： Twenty-two residual roots and crowns with low occlusogingival distance were involved in the study. The root canals were prepared according to their natural directions without concerning about the common path of insertion and then the preparation of abutment teeth were made following the routine clinical procedure. Accurate impression was taken with silicone to fabricate the custom casting separate post-and-core crown restorations of Ti. The two parts were cemented together with resin cement. RESULTS： All the 22 fixed restorations were found to be with good retention and without looseness, falling off or breaking off of the roots. They all used normally for 6-30months. CONCLUSIONS ： Custom casting separate post-and-core crown of Ti is a better prosthetic restoration for molar residual root and crown with low occlusogingival distance.
