Improving The Adult Dental Arch, And Airway, Through Bio-engineering And Dentofacial Orthopedics

It has been shown that FacialblockTM treatment has discernable affects on the maxillary arch, and face, in the correction of mild Class I and Class II malocclusions (Singh GD and Belfor TR, 2004). The case studies presented in this article show a pattern of poor swallowing and tongue posture. The appliance exhibits the ability to overcome and correct adult swallowing habits. We see changes in the alveolar arch, from the familiar ‘V’ shape to the more desirable ‘U’ shape, which provides more room for the tongue. Improved tongue position can affect the paryngeal airway. In accordance with Melvin Moss’ Functional Matrix Hypothesis, the functional matrix is comprised of all the tissues, organs, and glands carrying out a speci c function, such as mastication and swallowing. Moss theorised that the bone responds dynamically to changes in function. Hence by altering the function of swallowing we present a dynamic for the change in the shape of the bone. Furthermore, it is now recognised that craniofacial structure is a result of environmental and gene interaction (Moss, ML, 1997). We postulate the changes shown in the Facialblock patients result from gene expression.
