General considerations/ dental implant courses by Indian dental academy

Fishes and most reptiles have hinged jaws that can open wide and shut down on prey, which is processed little if at all before it is swallowed. The capability for anteroposterior jaw movement with the development of a sliding jaw joint with heterodont teeth marks a few advanced crocodilian reptiles and characterizes mammals. This chewing capability, associated with secondary palate development, has enabled exploitation of diets very different from those species with limited hinge movement. www.indiandentalacademy.com
