Summary
Immediately loaded hydroxyapatite-coated implants show predictable survival rates. Marginal bone loss was minimal and not significantly different between immediate and delayed loading groups after one year.
Area of Science:
- Dental Implantology
- Biomaterials Science
Background:
- Hydroxyapatite (HA) coatings enhance osseointegration of dental implants.
- Determining optimal loading protocols is crucial for implant success.
Purpose of the Study:
- To compare marginal bone resorption around HA-coated implants with immediate versus delayed loading.
- To evaluate the stability of HA-coated implants under different loading conditions.
Main Methods:
- Retrospective study of 41 patients over one year.
- Used Osstem TS III HA and Zimmer TSV-HA implants.
- Compared marginal bone loss via periapical radiography between immediate and delayed loading groups.
Main Results:
- 100% implant survival rate observed in all patients.
- Mean marginal bone loss was 0.26±0.59 mm overall.
- Immediate loading group: 0.32±0.69 mm; Delayed loading group: 0.16±0.42 mm (not significant).
Conclusions:
- Immediately loaded HA-coated implants demonstrate predictable survival rates within a one-year period.
- No significant difference in marginal bone loss was found between immediate and delayed loading groups.
