Summary
Mini-implants significantly improve denture stability, function, and comfort for patients. This study shows marked improvements in patient satisfaction and oral function after mini-implant placement for denture stabilization.
Area of Science:
- Dental Implantology
- Prosthodontics
- Patient-Reported Outcomes
Background:
- Complete dentures often suffer from poor stability, affecting function and patient comfort.
- Mini-implants offer a potential solution for stabilizing dentures and improving patient satisfaction.
Purpose of the Study:
- To evaluate patient-centered outcomes, specifically function and comfort, following the placement of mini-implants for complete denture stabilization.
- To assess the impact of mini-implants on patients' perceived satisfaction with their dentures over a 12-month period.
Main Methods:
- A prospective cohort study involving 21 patients (50-90 years) with unstable complete dentures.
- Flapless installation of 2-4 narrow-body Dentatus Atlas mini-implants, with existing dentures relined using Tuf-Link(®).
- Patient satisfaction, function, and comfort assessed using Visual Analogue Scales (VAS) and questionnaires at baseline, 1, and 12 months.
Main Results:
- Significant improvements in overall satisfaction, chewing, and speaking comfort, with median VAS scores rising from 4-5 to 9-10.
- Nearly 100% positive responses regarding denture stability and function at the 12-month follow-up.
- Higher risk of implant failure observed with maxillary dentures and short implants (7-10 mm).
Conclusions:
- Mini-implants provide a marked positive impact on patients' perception of oral function, comfort, and social confidence.
- The retentive capability of mini-implants significantly enhances the stability and usability of poorly fitting complete dentures.
- While effective, careful consideration of implant length and location is advised to mitigate failure risks.
