Summary
Mini dental implants (MDI) demonstrated good survival rates in a dental practice setting. However, denture base fractures and minor prosthetic complications require careful consideration.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Mini dental implants (MDI) offer a solution for improving the retention of removable dentures.
- Assessing their long-term survival and maintenance needs in a real-world clinical setting is crucial.
Purpose of the Study:
- To evaluate the survival rate of mini dental implants (MDI) used to support mandibular removable dentures.
- To quantify the prosthetic maintenance requirements associated with MDI-retained dentures.
Main Methods:
- A practice-based study analyzed patient records of 25 individuals who received 99 MDI.
- Kaplan-Meier curves and log-rank tests were employed to assess implant survival and prosthetic complications.
- Data were collected over a period of up to seven years.
Main Results:
- A 92% survival rate was observed for MDI after seven years, with initial failures occurring early.
- Implant survival was higher with complete maxillary dentures (94.9%) compared to partial dentures (81%).
- Denture base fractures occurred in 24% of cases, with minor complications including tooth fracture, retention ring changes, and relining needed for 16% of dentures.
Conclusions:
- Mini dental implants exhibit favorable mid-term survival rates in a clinical setting.
- The incidence of denture base fractures and other minor prosthetic complications necessitates attention and management.
