Abstract

The application of Cone Beam Computed Tomography (CBCT) in the field of dentistry has revolutionized the outlook of dental practitioners when diagnosing, treatment planning, and measuring treatment outcomes, because CBCT has wide-ranging applications in both oral surgery and in forensic odontology. Traditionally, airway volumetric assessments and boundary determinations were performed with 2-dimensional lateral cephalometric radiographs. However, the advent of CBCT makes it possible to precisely measure the Airway dimensions and volume, the presence of any constrictions, the position of the hyoid bone, and the position of the tongue relative to the palate. Disclusion Time Reduction (DTR) therapy is a novel, splint-less, measured occlusal calibration technique primarily aimed at decreasing nociceptive impulses arising from excess compressions of the pulpal and periodontal ligament mechanoreceptors of the teeth, which produce masticatory muscle, pharyngeal muscle, and glossal muscle hyperactivity. DTR therapy is carried out using the T-Scan 10/BioEMG III interface to measure the obtained reductions in muscular hyperactivity. However, the applications of DTR appear to extend beyond its' well known TMD therapeutic benefits, to also impact the airway, and the pharyngeal and tongue musculature. This chapter's Specific Aims are to discuss the role of CBCT in the evaluation of airway and its' related structures, along with describing how DTR therapy can dynamically and physiologically change the airway volume without requiring surgery or any mandibular advancement device.
