Summary
Calcium phosphate ceramic implants, including hydroxyapatite and tricalcium phosphate, did not delay tooth eruption or cause damage in dogs. These dental materials showed no adverse effects on eruption, dysplasia, or hard tissue resorption.
Area of Science:
- Biomaterials Science
- Dental Research
- Regenerative Medicine
Background:
- Calcium phosphate ceramics are widely used in dental and orthopedic applications due to their biocompatibility.
- Investigating their effect on tooth eruption is crucial for developing effective bone graft substitutes and regenerative materials.
Purpose of the Study:
- To evaluate the impact of different calcium phosphate ceramic particles on tooth eruption.
- To assess the radiographic and histologic effects of these implants on dental tissues.
Main Methods:
- Radiographic and histologic analyses were performed on 20 3-month-old dogs.
- Four types of calcium phosphate ceramic particles (dense/porous hydroxyapatite and dense/porous tricalcium phosphate) were implanted into deciduous tooth extraction sockets.
Main Results:
- All four types of calcium phosphate ceramic particles demonstrated similar radiographic and histologic outcomes.
- No delay in tooth eruption was observed.
- No instances of dental hard tissue dysplasia or resorption were detected.
Conclusions:
- Calcium phosphate ceramic implants, regardless of density or porosity, do not impede tooth eruption.
- These materials are safe for use in dental sockets, showing no adverse effects on eruption or surrounding hard tissues.
