Morphology of the temporomandibular joint in subjects with Class II Division 2 malocclusions.

Introduction: Temporomandibular joint (TMJ) morphology has not been studied adequately in subjects with various types of malocclusion, and it is not known if TMJ morphology and facial morphology are related. Such knowledge might assist in the establishment of biological treatment strategies, especially when the TMJ is the target of the treatment plan. The aim of this study was to explore the morphological characteristics of the TMJ in subjects with skeletal Class II Division 2 malocclusions.

Condyle and fossa shape in Class II and Class III skeletal patterns: a morphometric tomographic study.

Introduction: The purpose of this investigation was to study the shapes of the condyle and the glenoid fossa in patients with Class II Division 1, Class II Division 2, and Class III malocclusions.

Methods: Axially corrected tomograms of 189 patients were used (109 Class II Division 1, 47 Class II Division 2, and 33 Class III). Five points on the condyle and 7 on the outline of the fossa were digitized.

The treatment effect of mandibular protrusive appliances on the glenoid fossa for Class II correction.

A study was undertaken to determine the contribution of glenoid fossa modification in the correction of skeletal Class II malocclusions. Individually corrected lateral tomograms of 35 patients (18 boys and 17 girls) between the ages of 7.96 and 15.

The effect of mandibular protrusive (activator) appliances on articular eminence morphology.

In studying the response of the glenoid fossa to mandibular protrusive appliances, apart from the condyle, much attention has been focused on what happens to the posterior wall of the fossa (post-glenoid process). Remarkably, the articular eminence has been overlooked, although it is the most adaptive area of the temporomandibular joint. The purpose of this study was to explore the type of response of the articular eminence morphology to the use of mandibular propulsive appliances (activators).

Changes in articular eminence inclination during the craniofacial growth period.

The articular eminence of the temporomandibular joint dictates the path and type of condylar-disk complex movement. It has been suggested that a steep articular eminence inclination may predispose to temporomandibular joint dysfunction. When using functional appliances in orthodontic therapy, the bite registration is greatly affected by the articular eminence inclination.

The postglenoid tubercle: prevalence and growth.

Aim: To quantify the prevalence and growth of the postglenoid tubercle in a skull sample and in children.

Material: a) ninety skulls ranging in age from between 2 years and adulthood, b) sixtyfour corrected lateral tomograms of left and right temporomandibular joints of 32 boys and girls. Their age range was between 9 and 11 years.
