摘要:
Masticatory habit is a major factor determining the morphology of the craniofacial skeleton. The craniofacial skeleton essentially comprises a series of bony stress-bearing bridges forming a structural framework. The structural framework of the skull of dog has been described as a rigid trestle-like structure; it can be illustrated by mechanically removing nonresistant areas of bone. It is then found that a framework is produced which is partially rigid (cranium) and partly flexible (rostrum). It is postulated that the flexibility of the rostrum acts to absorb shock and it is suggested that the primate postorbital bar is developed in response to craniofacial morphology which increases compressive bite forces.
