Investigating activity of masticatory muscles in patients with hypermobile temporomandibular joints by using EMG.

Background: Temporomandibular joint hypermobility (TMJH) can manifest higher range of motions in mandible. The aim of this study was to investigate and compare the activity of masticatory muscle of TMJs in healthy individuals and patients with mild, moderate and severe TMJH.

Material And Methods: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of TMJH were included.

Condylar distances in hypermobile temporomandibular joints of patients with excessive mouth openings by using computed tomography.

Objectives: hypermobility in Temporomandibular joint (TMJ) can manifest higher range of motions in mandible. The aim of this study was to compare the position and distances of the head of condyle to glenoid fossa in TMJs of healthy individuals and patients with mild, moderate and severe TMJ hypermobility.

Material And Methods: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of joint hypermobility were included and Computed tomography were administered for both TMJs.
