An 8- to 10-Year Follow-up of Denture Satisfaction and Oral Health–Related Quality of Life with Implant-Retained Mandibular Overdentures

Abstract

Background: This 10-year follow-up study reports denture satisfaction and oral health-related quality of life of edentulous patients treated with two-implant mandibular overdentures. Methods: This is a follow-up of a previous study carried out between 1997-2005. Originally, the patients were randomly divided into two groups: one receiving two-implant mandibular overdentures (IODs) and another, relined mandibular dentures (RCDs). The latter group were offered and accepted IODs at two years, which then became another IOD group. The main outcome variable of this study is patient opinion over time of the IODs. The participants completed a self-administered questionnaire containing demographics, 15 variables of denture satisfaction, and 20 questions of the Oral Health-Related Impact Pro le (OHIP-20). Comparison between groups were made with Mann-Whitney U-tests for denture variables and T-tests for OHIP-20 variables. Changes over time were analysed with multilevel linear models for denture variables and multilevel ordinal regression analyses for OHIP-20 variables. Results: Of the 54 original participants, 29 responded. Disregarding patients who had died at 10 years, this represented a response rate 76%. In the IOD group, the degree of denture satisfaction and OHIP-20 scores remained high and stable over the 10-years period for all but one variable. The RCD group showed a modest improvement of denture satisfaction and OHIP-20 scores for the rst two years. After treatment with IODs, these variables improved at 10 years to the same level as the original IOD group. Conclusions: The positive effect on denture satisfaction and oral health-related quality of life of edentulous patients treated with two-implant mandibular overdenture remains unchanged 10 years after treatment, con rming the advice that this should be the standard treatment for the edentulous mandible.

Patient satisfaction and oral health‐related quality of life for four implant‐assisted mandibular overdentures fabricated with CAD/CAM milled poly methyl methacrylate, CAD/CAM‐milled poly ether ether ketone, or conventional poly methyl methacrylate: A crossover clinical trial

“…4 The type and quality of prosthetic appliances were reported as one aspect of oral health that affect the patient satisfaction and quality of life. 5,6 Despite recent improvements in dentistry, complete dentures were still regarded as the solution for individuals who were missing teeth in terms of appearance, functionality and social interaction. 7 With complete denture, there was some improvement in patient satisfaction and OHRQL.…”

“…The mandibular implant-assisted overdentures were evidenced in a number of studies to improve patient satisfaction and OHRQL. 5,6 This improvement is probably the result of better stability, retention, adaptation and chewing efficiency of the implant overdentures. 10,11 Therefore, the implant-assisted overdenture was recommended as the standard method for prosthetic rehabilitation of mandibular edentulous subjects.…”

Expedited Digital‐Analog Hybrid Method to Fabricate a 3D‐Printed Implant Overdenture

“…A complete prosthesis with dental implants and attachments aiding in retention of the prosthesis is considered a predictable and efficient treatment with a high degree of patient satisfaction. [1][2][3] Patients interested in implant stabilization of mandibular complete prostheses are historically treated with placement of two dental implants in the interforaminal region, followed by a clinical reline using a soft-reline material. After a period of implant osseointegration, the retentive abutments are placed, and an elastomeric impression made within the intaglio surface of the prosthesis using a functionally generated (aka "closed-mouth") reline technique.…”
