Mucosal Manifestations in the Edentulous Maxilla with Implant Supported Prostheses: Clinical Results from a Well-Maintained Patient Cohort

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
