Abstract

The frequent instability of mandibular removable complete dentures affects patient Oral Health Related Quality of Life (OHRQoL). An innovative therapeutic strategy used to improve stability involves placing four symphyseal mini-implants. This study was aimed at assessing OHRQoL over time in subjects in which mini-implants were placed and exploring if certain parameters could predict the evolution of their OHRQoL. The Quality of life of subjects with dentures was assessed using the Geriatric Oral Health Assessment Index (GOHAI) before (T0), 2–6 months (T1), twelve months (T2) and twenty-four or more months (T3) after mini-implant setting. Age, gender and chewing ability were tested as explanatory variables for the change in OHRQoL with time. Thirteen women and six men were included (mean age: 69 ± 10 years). After mini-implant placement, mean GOHAI scores at T1, T2 and T3 increased significantly (p < 0.001). The GOHAI-Add mean score was not affected by age or gender. Baseline chewing ability impacted the “functional” and “pain and discomfort” fields of the mean GOHAI scores (p < 0.05). The OHRQoL was quickly improved after mini-implant placement in complete denture wearers and then stabilized over time. Baseline chewing ability can be used as a predictive parameter of OHRQoL.

Highlights

The frequent lack of stability and retention of mandibular prosthesis in complete edentulous patients often results in dissatisfaction
Quality of Life this study, ten of subjects were evaluated on their chewing ability at T0 and T1
Other authors observed the same results [10]. All these results suggest that the quality of life of edentulous persons improved before stabilizing, whether mini-implant or conventional implant treatment was applied [9,10,19,21,23,24]

Summary

Introduction

The frequent lack of stability and retention of mandibular prosthesis in complete edentulous patients often results in dissatisfaction. The placement of two symphyseal implants to support mandibular dentures (overdenture treatment) is recommended as “the first choice standard of care for edentulous patients” by the McGill consensus statement and more recently by the York consensus statement [1,2]. Many geriatric edentulous patients have a variety of systemic diseases and frequently exhibit severe bone resorption that can make implant placement impossible. This treatment presents many disadvantages such as cost and an extended treatment period with delayed loading of the prosthesis [3,4]. An alternative treatment consists on the placement of four inter-foraminal mini-implants to stabilize the complete mandibular denture.
