Subjects between 18 and 27 years of age, of both sexes, were included, where 20 presented oral breathing diagnosis and 20 did not present this alteration; using lateral teleradiography
of the head and neck, craniocervical cephalometric analysis was performed of Rocabado and Penning technique was applied, obtaining craniocervical and hyoid measurements, anterior nasopharyngeal dimension and cervical curvature.
When completed, the PPP will establish the first teleradiography
service interconnecting the hospitals through the projects hub at the King Fahad Medical City.

Rocabado  proposes a teleradiography
method to objectively assess cephalic posture in anteroposterior and vertical direction using cephalometric measurements on a sagittal plane to define three parameters: a) hyoid position (hyoid triangle), b) anteroposterior cranio-cervical rotation, and c) suboccipital space cervical 0-cervical 1 (C0-C1); the influence of these parameters is emphasized in the harmony of dentofacial structures involving respiration, speech, voice, deglutition, and the limited clinical relevance given to the orthostatic stability of the skull on the cervical spine .
In 1988, Kaban et al (22) changed Pruzansky's classification by adding the description of deformations seen in temporomandibular joint teleradiography
. The greatest difference appears in Grade II, which presents two sub-classifications depending on position of the glenoid cavity, which may be normal (IIA) or altered (IIB) (table 1-B).

and 2 clinical procedures in 50 patients.
Full orthodontic documentation consists of intra and extraoral photographs, panoramic x-ray and lateral teleradiography
, periapical radiographs and study models (MELANI; SILVA, 2006; PARANHOS et al., 2011).
Many authors support the use of CR in occlusal rehabilitation therapy, (3,11) since they consider it an easily reproducible reference position, and also in orthodontics, (1,3) strongly advocating the need to plan any treatment by mounting study models on an articulator and performing diagnostic teleradiography
, both using CR.
