摘要： 目的:探讨数字化印模在全牙弓种植固定义齿修复中的临床效果。方法:获取已完成一期手术的全牙弓种植患者口内数字化印模,并在其基础上设计制作临时及永久修复结构,完成临时及永久固定义齿的修复,同时患者填写对数字化印模舒适度的视觉模拟量表(VAS)。根据修复体的就位、边缘适合性,患者舒适度及术后随访评价数字化印模在全牙弓种植修复中的临床效果。结果:全部临时及永久固定义齿均一次性精准被动就位,修复体适合度均达Ⅰ度;即刻义齿及永久义齿数字化印模舒适度评分分别为(84.2±2.4),(90.5±3.9)分;种植体的基台螺丝均未出现松动及断裂,牙槽骨吸收均在2 mm以内。结论:数字化印模应用于全牙弓种植固定义齿的修复有较高的精确性和患者舒适度及良好的临床预后。

Abstract: Objective: To investigate the clinical effect of digital impression in the restoration of fixed denture with full arch implantation. Methods: We obtained the digital impression in patients with complete dental arch implantation who had completed the first stage operation, then designed and fabricated temporary and permanent restoration structure to complete the restoration of fixed denture. At the same time, patients were asked to fill the visual analogue scale according to their comfort level to the digital impression. The clinical effect of digital impression was evaluated according to the position and marginal suitability of the prostheses, patient compfort level and postoperative follow-up. Results: All temporary and final fixed dentures were placed precisely in passive position at one time, and the fitness of prosthesis reached I degree. The comfort scores of immediate denture and permanent dentures were 84.2±2.4 and 90.5±3.9, respectively. The abutment screws of the implant were not loosened or broken, and the alveolar bone absorption was within 2mm. Conclusion: Digital impression has high accuracy, patient comfort level, and good clinical prognosis in the restoration of full arch fixed implant denture.
