Objective: To evaluate the clinical outcomes of digital technique-aided occlusal rehabilitation based on implant-supported fixed prostheses (ISFP), and to provide some information for clinical application of digital technique. Methods: Retrospectively reviewed the cases which had used neuromuscular system and condylar movement tracing device to reconstruct occlusion in one or double jaw fully edentulous ISFP from January, 2013 to January, 2020. A total of 6 eligible patients were enrolled in the present study with 56 implants and 8 ISFP, including 4 male patients and 2 female patients, aged from 43 to 74 years. The clinical outcomes were evaluated in four aspects, including implant survival rate, implants success rate, marginal bone loss and the occurrence of prosthesis complications. Results: The follow-up time was (4.0±2.2) years (1-7 years). The implant survival rate was 100% (56/56) and the implant success rate was 98% (55/56), with an average missal and distal marginal bone loss of (0.04±0.11) mm/year. Veneer chipping occurred at incisal edge of 2 adjacent incisors in only one prosthesis 3 years after rehabilitation. Conclusions: Combination of digital techniques of neuromuscular system and condylar movement tracing device to assist occlusal rehabilitation based on ISFP showed a high implant success rate. The complication seldom happened. Long and stable occlusion has been observed. The clinical outcomes were favorable.
目的： 评估数字化技术辅助下无牙颌种植固定修复咬合重建的临床效果，为数字化技术的临床应用提供参考。 方法： 回顾性纳入首都医科大学口腔医学院种植中心2013年1月至2020年1月联合应用神经肌肉分析系统和髁突运动轨迹描记系统进行单颌或双颌种植固定修复咬合重建的患者6例，男性4例，女性2例，年龄43~74岁，共植入56枚种植体，制作8件单颌种植固定修复体。从种植体存留率和成功率、近远中边缘骨吸收以及修复体并发症4个方面评价数字化技术辅助下无牙颌种植固定修复咬合重建的临床应用效果。 结果： 6例患者随访（4.0±2.2）年（1~7年），种植体存留率和成功率分别为100%（56/56）和98%（55/56），近远中边缘骨吸收为（0.04±0.11） mm/年，仅1件修复体的2颗相邻切牙切端于修复后3年崩瓷。 结论： 联合应用神经肌肉分析系统和髁突运动轨迹描记系统的数字化技术辅助种植固定修复咬合重建，种植体成功率较高，并发症发生数少，咬合长期稳定，临床修复效果良好。.
