Summary
Implant-retained overdentures (IRD) significantly improve denture satisfaction and chewing ability in patients with severely resorbed mandibles compared to complete dentures (CD). IRD offers a more satisfactory solution for denture-related problems.
Area of Science:
- Dental Prosthetics
- Implant Dentistry
- Oral Rehabilitation
Background:
- Severely resorbed mandibles pose significant challenges for complete denture (CD) wearers.
- Patients often experience poor denture satisfaction and impaired chewing ability with conventional CDs.
Purpose of the Study:
- To compare the treatment outcomes of implant-retained overdentures (IRD) versus complete dentures (CD).
- To assess patient-reported outcomes, specifically denture satisfaction and chewing ability, in edentulous patients with mandibular bone resorption.
Main Methods:
- A multicenter randomized clinical trial involving 151 patients with severely resorbed mandibles.
- Patients were allocated to either IRD or CD treatment groups.
- Denture satisfaction and chewing ability were evaluated using questionnaires before treatment and one year post-treatment.
Main Results:
- Before treatment, all patients reported dissatisfaction and difficulty chewing.
- One year after treatment, the IRD group showed high satisfaction, while only one-third of the CD group was satisfied.
- The IRD group demonstrated significantly better chewing ability compared to the CD group (p < 0.0001).
Conclusions:
- Implant-retained overdentures provide a more satisfactory solution for patients suffering from severely resorbed mandibles.
- IRD significantly enhances both denture satisfaction and functional chewing ability compared to conventional complete dentures.
