目的:探讨铸造纯钛分体桩核冠修复低龈距离磨牙的效果。方法:对22例患者的低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龈距离磨牙残根及残冠,可以取得较好的临床效果。
Objective: To investigate the effect of cast pure titanium split post crown on the restoration of molars with low gingival margin. Methods: Twenty-two patients with low gingival margin molars and residual crown were cast with pure titanium split post and core crown. The preparation of post-core along the direction of root canal of molars, preparation of abutment teeth according to the clinical repair routine, impression mold with injection silicone rubber impression material, production of pure titanium split post crown, resin cement for prosthesis bonding , To complete the repair. RESULTS: Twenty-two of the 22 patients underwent a well-maintained postoperative follow-up of 6 to 30 months without functional loosening, detachment or root fracture. CONCLUSION: Casting pure titanium split post and core crown for the restoration of remnant and crown of molar with low gingival margin can achieve better clinical results.
