Patient-Reported Outcomes of Maxillary Edentulous Patients Wearing Overdentures Retained by Two Implants from Insertion to 4 Years


Zembic, Anja; Tahmaseb, Ali; Jung, Ronald E; Wiedemeier, Daniel; Wismeijer, Daniel (2019). Patient-Reported Outcomes of Maxillary Edentulous Patients Wearing Overdentures Retained by Two Implants from Insertion to 4 Years. International Journal of Oral & Maxillofacial Implants, 34(2):481-488.

Abstract

PURPOSE
This cohort study evaluated patient satisfaction for maxillary implant-retained overdentures (IODs) on two implants up to 4 years and assessed the treatment effect over time.
MATERIALS AND METHODS
Patients encountering problems with their conventional dentures were included and received maxillary IODs on two titanium-zirconium implants and ball anchors in the canine area. Patient satisfaction was assessed using the oral health impact profile (OHIP-20E) questionnaires both for dentures and IODs. Two months after insertion of IODs (baseline), the patients chose the preferred overdenture design with full or reduced palatal coverage. OHIP-20E questionnaires were followed according to the individual choice at 1 and 4 years, and outcomes were compared with baseline.
RESULTS
Sixteen out of 21 patients were evaluated at a mean follow-up of 4 years (range: 2.4 to 4.8 years). There was no significant difference in the OHIP domains for IODs at 1 year (OHIP__: 9.5, SD: 13.0) and 4 years (OHIP__: 14.2, SD: 19.1) compared with baseline (OHIP__: 12.4, SD: 14.7). Patients were most satisfied with social disability both for IODs (OHIP_: 6.0, SD: 7.6; OHIP_: 3.4, SD: 5.4; OHIP_: 5.7, SD: 9.5) and dentures (OHIP__: 28, SD: 29.7; OHIP__: 25.4, SD: 28.67). Patients were least satisfied with functional limitation both for IODs (OHIP_: 6.0, SD: 7.6; OHIP_: 3.4, SD: 5.4; OHIP_: 5.7, SD: 9.5) and dentures (OHIP__: 28, SD: 29.7; OHIP__: 25.4, SD: 28.67).
CONCLUSION
Patient satisfaction with maxillary IODs on two implants did not change from baseline to 4 years and was high at 4 years of function.
