Comparison of the Centric Relation Recorded by the Gothic Arch Methods and the Neuromuscular Method Using Cone Beam Computed Tomography
The purpose of this study was to investigate and compare the variation in mandibular relation recorded by the gothic arch methods and the K7 method using cone beam computed tomography (CBCT)
ten asymptomatic participants were selected,the centric relation registrations were separately recorded according to the technique of the gothic arch method and the neuromuscular method,subsequent, they were instructed to perform CBCT wearing two bite registrations,thus using dophin software to calculate the tmj space and the upper airway and using exocad software to ananyse the mandibular position, Data were analysed with paired t-test
Inclusion Criteria:
absence of the mandibular position Classified as ASA 1 or 2 (normal healthy patient or with mild systemic disease, according to the American Society of Anaesthesiologists Physical Status Classification System); Absence of the symptoms and signs of the temporomandibular joint; Willing to participate and to sign a written informed consent form.
Exclusion Criteria:
Cardiac pacemaker carriers and pregnant women; people with heart pace disorders and epilepsy; Temporomandibular or craniocervical disorders.
