Abstract:
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.
