Prosthetic Treatment Time and Satisfaction of Edentulous Patients Treated with Conventional or Implant-Stabilized Complete Mandibular Dentures: A Case-Control Study (Part 2)

Purpose: The aim of this study was to compare, prospectively, treatment with implant-retained mandibular overdentures versus conventional complete dentures. Materials and Methods: Part 2 of this paper reports on the outcome after 7 years of denture use, using additional questionnaires. Results: Patients with implant-stabilized overdentures continued to be more satisfied with their mandibular dentures and their diet than those using conventional complete dentures. About 50% of the implant group who completed the questionnaire had had their dentures remade. The other 50% remained satisfied with their original dentures and were still using them at the 7-year review. The average chairside time spent on them was 467 minutes. Conclusions: Mandibular overdentures with two endosseous implants permit better function than conventional complete dentures.
