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

the temporomandibular joint space
according to the method of Ikeda and Kawamura, tmj space measurement in sagittal of the CBCT images were performed
Time frame: immediately
the upper airway
Using the sinus/airway feature of the Dolphin software to reconstruct the upper airway,it included three region: the nasopharynx, oropharynx, and hypopharynx
