Osseointegrated implants for single tooth replacement: a 1-year report from a multicenter prospective study.
The International Journal of Oral & Maxillofacial Implants
|January 11, 1991
Summary
Dental implants show high success rates for single tooth restorations, with only 2.8% loss after one year. While esthetics and gingival health were good, loose abutment screws required retightening in 26% of cases during the initial observation period.
Area of Science:
- Dentistry
- Biomaterials Science
- Clinical Research
Background:
- Single tooth restorations are crucial in restorative dentistry.
- Dental implants offer a viable solution for replacing missing teeth.
- Assessing the long-term clinical performance of dental implants is essential.
Purpose of the Study:
- To evaluate the clinical success and complications of dental implants supporting single tooth restorations.
- To assess the esthetic outcomes and gingival health around single-implant crowns.
- To identify common issues during the first year of function.
Main Methods:
- Prospective, multicenter investigation involving 92 patients.
- 107 dental implants were placed for single tooth restorations.
- Clinical function, esthetics, gingival condition, and screw loosening were monitored for 1 year.
Main Results:
- Implant survival rate was high, with only 2.8% loss after 1 year.
- Most restorations achieved esthetic success with modified components.
- Healthy gingival conditions were observed around the single crowns.
- Loose abutment screws were the most frequent complication, requiring retightening in 26% of restorations, with a decreasing trend over time.
Conclusions:
- Dental implants are a reliable option for single tooth replacement with high survival rates.
- Esthetic and periodontal parameters are generally favorable.
- Abutment screw loosening is a manageable complication that may decrease with continued observation.
