Summary
Mandibular three-implant overdentures significantly improved patients' oral health-related quality of life. Most patients were satisfied with the prostheses, reporting minimal rocking movements, indicating favorable outcomes.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Health-Related Quality of Life (OHRQoL)
Background:
- Three-implant overdentures are frequently used for edentulous mandibles.
- Limited clinical studies exist to support their efficacy.
- Patient-reported outcomes require further investigation.
Purpose of the Study:
- To evaluate changes in OHRQoL after mandibular three-implant overdenture treatment.
- To assess patient satisfaction with mandibular three-implant overdentures.
- To identify factors influencing OHRQoL changes.
Main Methods:
- Quasi-experimental study involving 135 edentate participants.
- Oral Health Impact Profile (OHIP-20) assessed OHRQoL at baseline and follow-up.
- Denture satisfaction and rocking movement perception were measured post-treatment.
Main Results:
- Statistically significant improvements in all seven OHIP-20 domains were observed (P < 0.001).
- 75.6% of participants reported complete satisfaction with their overdentures.
- 81.5% experienced no rocking movement; satisfaction was independent of gender, fixture, or attachment type.
Conclusions:
- Mandibular three-implant overdentures yield favorable patient-reported outcomes.
- Negligible perceptions of rotational movement were reported.
- Further research is needed to compare with other treatment options like two-implant overdentures.
