Abstract

Abstract: Background: Prostheses in the edentulous maxilla affect the mucosa. Purpose: To evaluate mucosal alterations with implant supported fixed prostheses (FDP) and overdentures (IOD). Material and Methods: Patients receiving prostheses during a time period of 10 years were recruited. Maxillary mucosal conditions in relation to FDPs, IODs were analyzed. Peri‐implant parameters were measured and the Oral Health Impact Profile (OHIP) was administered. Results: One hundred seven patients wearing 74 IODs and 33 FDPs were identified with a total of 519 implants, the mean observation time was 6.5 ± 2.7. Cumulative implant survival was 93%. Erythema and hyperplastic tissue were identified in 71% of the IOD wearers, but were mostly absent with FDPs. The peri‐implant parameters demonstrated healthy peri‐implant mucosa. Medication and smoking had no effect on mucosal alteration (OR = 1.065 and 1.568). The average OHIP value was 3.73 ± 4.12. A lower value ( p < 0.0048) was found for FDPs and one type of IOD. Conclusions: A rigorous maintenance program did not prevent IOD mucosal alterations in IOD wearers, but the health of the peri‐implant mucosa was maintained and was comparable for all types of prostheses.
