Abstract:
Objective:To evaluate long-term clinical outcome of implant-supported fixed prosthesis with the guidance of computer-aided design/computer-aided manufacturing (CAD/CAM) surgical template in old patients.Methods:Fifteen 50-67(58.6±5.3) year-old patients (11 males and 4 females) who received the digital implant surgery with the guidance of CAD/CAM surgical template and implant-supported fixed prosthesis in Department of Oral Implantology, Yantai Stomatological Hospital Affiliated to Binzhou Medical College from August, 2013 to Janurary, 2016 were included. There are 15 edentulous maxillas, 8 edentulous mandibles on which 145 implants were placed in total. After the placement of implant, the accuracy of CAD/CAM surgical template was assessed by comparing the post-operative 3-dimensional location of implant with the pre-operative design. The 5-year survival rate of implant and prosthesis was recorded, and marginal bone loss around implants and the development of complication were evaluated by radiological and clinical examination respectively.Results:The result on accuracy of CAD/CAM surgical template showed that deviations in neck and apex of implants were (0.78±0.59) and (1.38±0.63) mm respectively, depth deviation was (0.65±0.35) mm and angle deviation was 4.12°±2.77°. The 5-year cumulative survival rate of implants was 98.6%(143/145). In all 145 implants, the prevalence of implant-related biological complication was 4.1%(6/145). The prosthesis-related mechanical complication rate was 57%(13/23). After 5-year function, mean peri-implant bone loss was (0.69±0.35) mm.Conclusions:This 5-year follow-up retrospective study showed that implant-supported fixed prosthesis with the guidance of CAD/CAM surgical template in middle aged and elderly patients could achieve good long-term clinical outcome and patient satisfaction.
