He achieved that through development of functional regulator appliances. These appliances allowed him to train and reprogram the musculature around the mouth. He published around 70 articles which stressed the importance of his appliance in expanding the dental arches. [3]
The MNTN is involved in reflex proprioception of the periodontium [8] and of the muscles of mastication in the jaw [9] that functions to prevent biting down hard enough to lose a tooth. To subserve this reflex protective function, mechanoreceptive nerves in the periodontal ligament sense tooth movement and project to the mesencephalic nucleus.

Dental anatomy is also a taxonomical science: it is concerned with the naming of teeth and the structures of which they are made, this information serving a practical purpose in dental treatment. Usually, there are 20 primary ("baby") teeth and 32 permanent teeth, the last four being third molars or " wisdom teeth ", each of which may or may ...
