Summary
Six mm wide tapered hydroxyapatite-coated implants show a 100% survival rate in dental implantology. This study indicates promising results for high survival rates with these specific dental implants.
Area of Science:
- Dentistry
- Oral Surgery
- Biomaterials
Background:
- Five- and 6 mm diameter screw-type endosseous implants have variable success rates.
- Some studies report high success (94-98%), while others show lower rates (75-87%).
- These implants are linked to increased cervical bone resorption and thread exposure.
Purpose of the Study:
- To evaluate the survival rate and bone remodeling of 6 mm diameter tapered hydroxyapatite (HA)-coated implants.
- To assess the clinical performance of these implants in patients receiving fixed prostheses.
Main Methods:
- 43 patients received 45 HA-coated implants (6 mm diameter, tapered) between 1999 and 2003.
- Implants supported fixed prostheses, mostly single-tooth restorations.
- Follow-up was annual, with a mean loading time of 23.4 months.
Main Results:
- 100% implant survival rate observed, with no losses during the loading period.
- Crestal bone remodeling assessed via radiographs showed minimal bone loss.
- Only one implant exhibited bone loss beyond the first thread after a mean of 23.4 months.
Conclusions:
- High survival rates are achievable with 6 mm-wide tapered HA-coated implants.
- These implants demonstrate favorable outcomes in prosthetic treatment.
- Further long-term prospective studies are recommended to validate these findings.
