简要总结
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)
详细描述
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

研究组 & 干预措施
record the centric relation using the gothic tracing method
the vertical dimension of occlusion (VDO) were were determineded through facial appearance observation,thus,the patients were trained to execute bordering protrusive, retrusive and bilateral lateral-protrusive movements wearing the intraoral apparatus and a Gothic Arch Tracing was made, the apex of the Gothic Arch Tracing was defined as the gothic arch position.
干预措施: the centric relation (Procedure)
record the centric relation using the neuromuscular method
the participant were subjected to a low-frequency transcutaneous electrical nerve stimulation (TENS) using the J5 Myotronics for 45 minutes,With the help of TENS, complete relaxation of the muscles were achieved and the mandibular musculature was induced to guide the mandible in the physiologic position,thus using K7 to track the physical mandibular positon which was defined as the neuromuscular position.
