Summary
Mini dental implants show a promising 94.7% first-year survival rate for definitive prosthodontic treatment. However, long-term survival data remains insufficient for conclusive evidence.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials Science
Background:
- Mini implants are widely used in orthodontics and for temporary prosthodontic solutions.
- Evidence supporting their use in definitive prosthodontic treatment is limited and requires further investigation.
Purpose of the Study:
- To systematically review the existing literature on mini dental implants.
- To analyze short-term, medium-term, and long-term survival rates for definitive prosthodontic applications.
Main Methods:
- Conducted an electronic literature search of PubMed and Cochrane databases (1974-2012).
- Included studies on mini, narrow, reduced, small, transitional, interim, and provisional implants.
- Calculated 1-year interval survival rate (ISR) and cumulative survival rate (CSR) from 9 selected studies.
Main Results:
- Identified 9 studies meeting inclusion criteria, primarily retrospective and prospective designs.
- The first-year ISR was 94.7%, with most failures occurring within the first year.
- Cumulative survival rate over 9 years was 92.2%, largely based on one study.
Conclusions:
- The first-year survival rate of mini dental implants is encouraging for definitive prosthodontic use.
- Data limitations, including short follow-up periods, obscure the true 1-year survival rate.
- Insufficient evidence exists to determine medium-term and long-term survival rates for mini implants in definitive prosthodontics.
