Abstract

Objectives: To evaluate the benefits of implant therapy for patients with diabetes, we compared (i) healthy, (ii) well controlled T2DM and (iii) poorly controlled T2DM patients, in terms of oral health-related quality of life (OHRQoL) and satisfaction with mandibular 2-implant overdentures over 12 months following restoration. Materials and methods: This single-center, prospective, cohort study recruited 165 edentulous adults (HbA1c<12%) to receive two endosseous implants in the anterior mandible to support mandibular overdentures. Participants were enrolled as having T2DM or not, with T2DM participants divided according to HbA1c into well-controlled (<8.1%) and poorly controlled (≥ 8.1%) groups. Participants provided responses to the OHIP-20 (OHRQoL) and the McGill Denture Satisfaction Questionnaire, before implant therapy and 6 and 12 months after overdenture insertion using Locator attachments. HbA1c was measured at the same time points. The effect of groups and time was verified using generalized estimating equations (α=0.025). Results: At 12 months, 137 participants provided responses. The two diabetes groups showed improvements in OHRQoL to the same extent as the non-diabetic control group at both 6 and 12 months. Patient satisfaction showed similar improvements with no between-group differences and similar increases identified at 6 and 12 months. HbA1c was not affected by time or groups. Conclusions: Dental implant therapy provided significant improvements in patient-perceived benefits of mandibular two-implant overdentures for T2DM individuals, which are similar to those found for healthy edentulous individuals. Importantly, those benefits extend to those individuals with poorly controlled glycaemia. The addition of 2-implant supported mandibular overdentures did not affect glycaemic status over 12 months following insertion. Clinical Significance: As risks for implant therapy relative to glycaemic status are better understood, this study documents that implant therapy may offer important benefits in QoL for T2DM patients independent of glycaemic status.
