Effect of calcium phosphate ceramic implants on tooth eruption
1Department of Oral and Maxillofacial Surgery, Ohio State University College of Dentistry, Columbus 43210.
Summary
Hydroxylapatite implants impeded tooth eruption and development in kittens, while tricalcium phosphate implants had minimal effects. This research highlights the differing impacts of calcium phosphate ceramics on dental development.
Area of Science:
- Biomaterials Science
- Developmental Biology
- Veterinary Dentistry
Background:
- Calcium phosphate ceramics are widely used in bone and dental regeneration.
- Understanding their impact on developing dentition is crucial for clinical applications.
Purpose of the Study:
- To evaluate the effects of hydroxylapatite and tricalcium phosphate implants on tooth eruption and development in a feline model.
Main Methods:
- Primary mandibular premolars were extracted from 40 kittens.
- Extraction sockets were grafted with hydroxylapatite, tricalcium phosphate, autogenous cancellous marrow, or left empty.
Main Results:
- Nonresorbable hydroxylapatite impeded tooth eruption and distorted crown development.
- Tricalcium phosphate exhibited minimal negative effects on tooth eruption and development.
Conclusions:
- Hydroxylapatite's nonresorbable nature can interfere with normal tooth eruption and development.
- Tricalcium phosphate appears to be a more suitable biomaterial for dental applications involving developing teeth.
