“…The different morphological variations of the TMJ components play an important role in understanding the TMJ's normality, function, and potential diseases to provide proper management and treatment (11). Several studies have investigated the relationship between the morphological and morphometric variations of the TMJ associating them with pathological changes according to sex and age groups (15,20,26,37). The TMJ is constantly remodeling according to the individual's development and adapting according to the non-functional changes that occur in the stomatognathic system.…”

“…When the balance between the joint's adaptive capacity and the stresses placed on the joint is lost, dysfunctional remodeling can cause changes in the condyle shape, size, and volume (15). Teeth provide a stable vertical and horizontal relationship between the mandible and the maxilla and provide orientation plans for the anterior and lateral movement of the mandible; thus, tooth loss is an important factor in the condyle morphological alterations (15). In a previous study, the loss of posterior teeth was accompanied by a significant decrease in the height of the condyle and an increase in the width of the condyle without alteration in its total volume (15).…”

“…The mandibular condyle has an ellipsoid shape and presents on average a medio-lateral dimension of 17.04 mm to 20 mm, while its average anteroposterior dimension varies from 5.12 mm to 9.6 mm (10,11,14,15,19,25). In the axial view, the condyles show unaligned poles which present their major axis not perpendicularly aligned with the median sagittal plane; hence, the condyle's lateral pole is positioned anteriorly to the medial pole.…”

“…The complexity of TMJ morphology has driven researchers to investigate its morphologic and morphometric features and their relationship with temporomandibular disorders (TMD) (5). Various image modalities have been used to assess TMJ's morphology, i.e., magnetic resonance imaging (MRI), computed tomography (CT), cone beam computed tomography (CBCT), ultrasound (US) and panoramic radiography (PR) (2,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). Conventional bidimensional images of the TMJ present distortions and are not acceptable for morphometric assessments, while US images are not usually used on morphometric analysis.…”

The temporomandibular joint (TMJ) is a synovial joint classified for its surface shape and complex biaxial movements as a ginglimoartrodial joint and presents the widest joint range of movements when compared with the other joints of the human body. The complexity of TMJ morphology has driven researchers to investigate its morphometric features and their relationship with temporomandibular disorders (TMD). Therefore, the knowledge of morphological and morphometric data of each bone component of the TMJ is of paramount importance for identifying bone changes related to the TMJ, in the presence of TMD in symptomatic and non-symptomatic patients. This literature review aims to assess previous studies on the TMJ bone structures morphological and morphometric findings and discuss what these findings implicate on TMDs. The assessed studies varied in sample size and categorization, and measurement methodologies [measurements done directly on specimen, image modality-computed tomography (CT), cone beam computed tomography (CBCT), magnetic resonance imaging (MRI)], study method of choice and main morphometric points). Morphometric measurements of the condyle, articular fossa and articular eminence were assessed in different planes (axial, sagittal and coronal). Male patients present higher condyle and glenoid fossa morphometric measurement values than female patients, however, when considering the articular eminence's inclination/steepness the gender difference is not conclusive. When more than one image method was assessed, a slight difference has been observed between the image modalities. It can be concluded that large, paired samples and longitudinal studies using non-ionizing images are still needed to assess the TMJ morphometric values and its association with internal disorders, age, ethnicity, and gender.
