Anatomic and histological study of the rabbit mandible as an experimental model for wound healing and surgical therapies

Abstract

The rabbit is one of the most widely used models for studying bone remodeling or dental implant osseointegration but very few data are available about the rabbit’s mandible. The aim of this work was to describe the anatomy of the rabbit mandible and to estimate the available bone volume for experimental studies. First, with a dissection, the morphology of the mandible was described and the mental foramen, the position of the main salivary glands and muscular insertions were located. Then, by X-ray imaging, the position of the inferior alveolar canal, the dental root courses and volume and bone density were described. Finally, with frontal sections of the mandible body, the rabbit’s dental and alveolar bone histological structure were assessed. Thus, the relevance of the rabbit mandible as an experimental model for wound healing or surgical therapies was discussed.
