Histological response to ivory implanted in rabbit mandibles
Journal of Dental Research
|May 1, 1975
Summary
Ivory rod implants were biologically unacceptable in rabbit mandibles, causing fibrous tissue formation and resorption. Bone deposition and ankylosis were not observed, indicating poor integration of ivory implants.
Area of Science:
- Biomaterials Science
- Oral and Maxillofacial Surgery
- Veterinary Pathology
Background:
- Dental implants aim for osseointegration and long-term stability.
- Biocompatibility of implant materials is crucial for successful integration.
- Rabbit mandible model is used for preclinical evaluation of bone-anchored devices.
Purpose of the Study:
- To evaluate the biological response and osseointegration potential of ivory rod implants in rabbit mandibles.
Main Methods:
- Ivory rods were implanted into rabbit mandibles.
- Histological analysis was performed to assess tissue response around implants.
Main Results:
- Ivory implants elicited a foreign body reaction, forming fibrous capsules with multinucleated giant cells.
- Significant resorption of the ivory material was observed.
- No evidence of osteoid deposition or ankylosis at the implant-bone interface.
Conclusions:
- Ivory is biologically unacceptable as an implant material in rabbit mandibles.
- The observed resorption and inflammatory response preclude its use in bone augmentation or fixation.
