Clinical follow-up observation of 84 cases of implant-retained/supported prostheses in edentulous patients / 中华口腔医学杂志

ABSTRACT

Objectives@#To evaluate the long-term clinical results and patient satisfaction of implant-retained/supported prostheses in edentulous patient based on retrospectively summary of the clinical data of implant-retained/supported prostheses patients.@*Methods@#Edentulous patients who received implant denture treatment between 01/2005 and 12/2016 was included in this study. Soft tissue health, clinical examination, X-ray observation, patient satisfaction with implant-retained/supported prostheses were evaluated.@*Results@#A total of 400 implants in 84 cases (96 jaws), 35 fixed bridges and 61 overdentures. The follow-up time was (34.3±25.5) months. The 3- and 5-year implant cumulative survival rate of implant-supported overdenture was 95.0% and 92.1%, and the 3- and 5- year survival rate of implant-supported fixed denture was both 99.9%. The prevalence of peri-implantitis was 2.8% (11/400). A total of 44% (27/61) of the overdenture and 23%(8/35) of the fixed denture were repaired due to the complications of prosthesis. The mean repair frequency was (1.4±1.2) in overdenture and (1.3±0.9) in fixed denture (t=0.490, P=0.600). The average probing depth around implant recorded in the overdenture group [(2.2±1.1) mm] was significantly greater than that in the fixed denture group [(1.4±1.2) mm] (t=3.300, P=0.002). Patient satisfaction with an average of (6.5±4.9) in implant-support overdenture group was significantly higher than that in implant-support fixed denture group (3.2±2.8) (t=3.218, P=0.006).@*Conclusions@#The complication rate of the prosthesis was high in edentulous patients with implant-retained/supported prostheses. Besides, the patients with implant supported denture expressed more satisfaction with their prostheses. And there was a relatively high implant cumulative survival rate of implant-retained/supported prostheses in edentulous patient.
