Abstrakt: Introduction: Palateless overdentures (PLODs) provide advantages of improved taste perception and retention over conventional dentures. We aimed to evaluate 5-year outcomes of four implant maxillary PLODs.
Methods: In this prospective observational study, edentulous participants were enrolled. A new conventional maxillary denture was prepared followed by implant placement and insertion of four implant retained maxillary PLOD. Oral health quality of life was assessed using the 49-item Oral Health Impact Profile (OHIP-49) at multiple intervals over 5 years along with biological and mechanical outcomes.
Results: Nine patients were evaluated at year 5. The mean age was 68 years, and six of the nine patients were males. The cumulative survival rate of implants was 100% while the implant success rate was 86%. Nylon retentive replacement was the most common encountered complication noted approximately four times per patient over 5 years. From a mean OHIP-49 severity score of 71.2 at baseline, severity scores decreased to 23.9 (p < 0.001) at year 1, denoting a clinically meaningful and statistically significant improvement in oral health quality of life. The lowered OHIP-49 severity scores remained stable throughout 5 years of follow-up.
Conclusion: Four implant supported maxillary overdenture appears to have good patient perceived, biological and mechanical outcomes over 5 years. Fully powered studies are needed to replicate these findings.
