Summary
Mandibular bone height does not impact patient satisfaction with dentures. However, 2-implant overdentures (IODs) provide greater satisfaction and function than conventional dentures (CDs) for edentulous elders.
Area of Science:
- Dentistry
- Prosthodontics
- Oral Implantology
Background:
- Edentulous elders often experience reduced quality of life due to conventional dentures.
- Mandibular bone height is a critical factor in denture stability and patient satisfaction.
Purpose of the Study:
- To investigate the influence of mandibular bone height on patient satisfaction and function with 2-implant overdentures (IODs) versus conventional dentures (CDs).
Main Methods:
- 214 edentulous elders received maxillary CDs and either mandibular CDs or IODs.
- Mandibular bone height was assessed using panoramic radiographs.
- Patient satisfaction was measured using the McGill Denture Satisfaction Instrument at baseline and 6 months.
Main Results:
- Mandibular bone height did not significantly affect patient satisfaction with general satisfaction, chewing, stability, comfort, aesthetics, or speech.
- Patients reported significantly higher satisfaction with IODs compared to CDs across all assessed parameters.
- IOD treatment was a significant predictor of higher satisfaction ratings, independent of mandibular bone height.
Conclusions:
- Mandibular bone height does not influence patient satisfaction with denture function, chewing ability, or comfort.
- Edentulous elders experience superior outcomes with mandibular IODs compared to conventional dentures, irrespective of their mandibular bone height.
