Computerized ultrasonic axiographic evaluation of condylar movement in patients with internal derangement of the temporomandibular joint.

Objectives: To evaluate condylar movement during lateral excursion in individuals with internal derangement of the temporomandibular joint (TMJ) using ultrasonic axiography.

Materials And Methods: A total of 34 patients with internal derangement of the TMJ and 34 participants in the control group were examined. Mandibular functional movement was recorded by ultrasonic axiography.

Dentofacial characteristics in orthodontic patients with centric relation-maximum intercuspation discrepancy.

Introduction: To investigate dentofacial characteristics of orthodontic patients with centric relation (CR)-maximum intercuspation (MI) discrepancy and to analyze changes in dentofacial characteristics between CR and MI positions in these patients using lateral cephalograms.

Materials And Methods: Adult female patients were classified into two groups: large CR-MI discrepancy (greater than 2.0 mm horizontal or vertical mandibular incisor movements during CR to MI change, n  =  20) and small CR-MI discrepancy (less than 1.
