Case Studies

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.

Airway Development Through Dental Appliance Therapy

We as dentists are very aware that our 21st century jaws are developing smaller. Modern humans’ facial structures are slowly shrinking, which can narrow the upper airway. This is evidenced by the fact that rates of malocclusion and impacted (or non-existent) wisdom teeth are increasing in modern, Westernized countries [1]. Sleep related disorders such as sleep apnea and upper airway resistance syndrome are on the rise. Although rising levels of obesity heavily influences the increasing rates of obstructive sleep apnea (OSA), detailed analysis of more basic etiology suggests a possible craniofacial origin [2]. The purpose of this article is to suggest that some of our lack of jaw development can be reversed in so called non-growing adults through oral appliance therapy and epigenetics resulting in better sleep and breathing.
