Assessment of craniocervical posture in TMJ disorders using lateral radiographic view: A cross-sectional study.

: To determine the craniocervical posture in 120 subjects, 90 patients with temporo- mandibular joint disorders (TMD) of varying degrees were selected and compared with those of 30 healthy individuals.: True lateral radiographs in the natural head position were obtained from TMD patients and healthy individuals. Linear measurements from the opisthion to the intersecting point of the craniovertebral angle, the opisthion to the tip of the spinous process of the seventh cervical vertebrae, and the body of Atlas to the lower border of the seventh cervical vertebrae were obtained.

Evaluation of vertical facial height reduction and severity of temporomandibular joint disorders using Shimbashi number and cephalometric analysis.

: This study was designed to evaluate the correlation between vertical dimension at occlusion (VDO) and various grades of temporomandibular disorders (TMDs) versus controls.: Clinically measured Shimbashi number and radiographic cemento-enamel junction (CEJ-CEJ) measurements on 120 TMD patients and 40 controls were evaluated. Radiographic lateral cephalometric skull images of the patients were subjected to cephalometric analysis.

Applications of cone beam computed tomography for a prosthodontist.

Cone beam computed tomography (CBCT) is a medical imaging technique of X-ray computed tomography where the X-rays are divergent, forming a cone. CBCT systems have been designed for imaging hard tissues of the maxillofacial region. The increasing availability of this technology provides the dental clinician with an imaging modality capable of providing a three-dimensional representation of the maxillofacial skeleton with minimal distortion.

Fundamentals of cone beam computed tomography for a prosthodontist.

Cone beam computed tomography (CBCT, also referred to as C-arm computed tomography [CT], cone beam volume CT, or flat panel CT) is a medical imaging technique of X-ray CT where the X-rays are divergent, forming a cone.[1] CBCT systems have been designed for imaging hard tissues of the maxillofacial region. CBCT is capable of providing sub-millimeter resolution in images of high diagnostic quality, with short scanning times (10-70 s) and radiation dosages reportedly up to 15-100 times lower than those of conventional CT scans.
