Summary
Implant-assisted removable partial dentures (IARPDs) and conventional removable partial dentures (RPDs) showed similar prosthetic complication rates and patient satisfaction. This study compared these two denture types over 34 months.
Area of Science:
- Dentistry
- Prosthodontics
- Implantology
Background:
- Limited data exists comparing prosthetic complications and patient satisfaction between implant-assisted removable partial dentures (IARPDs) and conventional removable partial dentures (RPDs).
- Partially edentulous patients are often treated with RPDs, but outcomes with implant support are less understood.
Purpose of the Study:
- To compare patient satisfaction and the incidence of prosthetic complications between conventional RPDs and short implant-assisted RPDs (IARPDs).
- To evaluate these outcomes over a mean observational period of 34 months in a randomized controlled trial.
Main Methods:
- 31 partially edentulous patients (Kennedy Class I) were randomized into conventional removable partial denture (CRPD) or IARPD groups.
- IARPD patients received two short implants after initial prosthesis delivery, which were then converted to IARPDs using LOCATOR attachments.
- Statistical analysis included chi-squared, log-rank, and Mann-Whitney U tests.
Main Results:
- Prosthetic complications occurred in both CRPD and IARPD groups, with no statistically significant difference in incidence (P=.474).
- Survival rates and complication occurrences also showed no significant difference between the groups (P=.903).
- Patient satisfaction levels were comparable between the conventional and implant-assisted groups (P=.938).
Conclusions:
- No statistically significant difference was found in the incidence or type of prosthetic complications between conventional RPDs and short implant-assisted RPDs after a mean follow-up of 34 months.
- Patient satisfaction was also similar for both treatment modalities.
