Three-dimensional cone-beam computed tomography based comparison of condylar position and morphology according to the vertical skeletal pattern
TL;DR: Condylar position and morphology vary according to vertical facial morphology, and this relationship should be considered for predicting and establishing a proper treatment plan for temporomandibular diseases during orthodontic treatment.

Abstract: Objective: To compare condylar position and morphology among different vertical skeletal patterns. Methods: Diagnostic cone-beam computed tomography images of 60 adult patients (120 temporomandibular joints) who visited the orthodontic clinic of Hallym University Sacred Heart Hospital were reviewed. The subjects were divided into three equal groups according to the mandibular plane angle: hypodivergent, normodivergent, and hyperdivergent groups. Morphology of the condyle and mandibular fossa and condylar position were compared among the groups. Results: The hypodivergent and hyperdivergent groups showed significant differences in superior joint spaces, antero-posterior condyle width, medio-lateral condyle width, condyle head angle, and condylar shapes. Conclusions: Condylar position and morphology vary according to vertical facial morphology. This relationship should be considered for predicting and establishing a proper treatment plan for temporomandibular diseases during orthodontic treatment.

Comparison of condylar size among different anteroposterior and vertical skeletal patterns using cone-beam computed tomography.
Atsushi Hasebe,Tetsutaro Yamaguchi,Takatoshi Nakawaki,Yu Hikita,Koushu Katayama,Koutaro Maki +5 more
TL;DR: Condylar height and width considerably differed among subjects with different anteroposterior or vertical skeletal patterns, and two-way analysis of covariance was applied to estimate the composite effect of skeletal patterns in both directions.

Temporomandibular condylar morphology in diverse maxillary-mandibular skeletal patterns: A 3-dimensional cone-beam computed tomography study.
TL;DR: The concept that morphology and symmetry of the temporomandibular joint varies in different skeletal patterns, presumably as an adaptive response to functional demands, is supported.

Mostafa Md Anisuzzaman,Safiquer Rahman Khan,Mohammad Tariqul Islam Khan,Kamal Abdullah,Alia Afrin +4 more
TL;DR: Shapes of the mandibular condyle also evaluate by OPG which showing ovaloval being most accepted in both genders is shown, due to low radiation exposer and availability.
Comprehensive three-dimensional positional and morphological assessment of the temporomandibular joint in skeletal Class II patients with mandibular retrognathism in different vertical skeletal patterns
S. A. Al-hadad,E. S. Alyafrusee,Abbas Ahmed Abdulqader,W. S. Al-gumaei,Rana A. A. M. AL-Mohana,Liling Ren +5 more
TL;DR: Wang et al. as mentioned in this paper used 3D cone-beam computed tomography (CBCT) analysis to evaluate the positional and morphological characteristics of the temporomandibular joint (TMJ) in adults with skeletal Class II.

TL;DR: Comprehensive image analysis criteria for the RDC/TMD Validation Project were developed, which can reliably be used for assessing OA using CT and for disc position and effusion using MRI.
Radiographic examination of the temporomandibular joint using cone beam computed tomography
TL;DR: Cone beam CT (CBCT) is a new technique for maxillofacial imaging that provides a complete radiographic investigation of the bony components of the TMJ and is of high diagnostic quality.

Assessment of optimal condylar position with limited cone-beam computed tomography
Kazumi Ikeda,Akira Kawamura +1 more
TL;DR: These data from optimal joints might serve as norms for the clinical assessment of condylar position obtained by limited cone-beam computed tomography, and showed less variability of condyle position in the fossa than previously reported in normal subjects.

Condyle and fossa shape in Class II and Class III skeletal patterns: a morphometric tomographic study.
TL;DR: Condylar and fossa shapes were found to be different between the groups; the Class III group had a more elongated and anteriorly inclined condylar head and a wider and shallower fossa.

Disc displacement within the human temporomandibular joint: a systematic review of a ‘noisy annoyance’
TL;DR: To describe the scientific literature about the diagnosis, prevalence, aetiology, natural course and possible treatment modalities of disc displacements within the temporomandibular (TM) joint, PubMed was searched for specific indexing terms.
