Introduction. Musculo-articular contracture of the lower jaw is a challenging issue in oral and maxillofacial surgery, despite extensive research in this area. While this condition presents a diverse range of clinical manifestations, it has received little attention in the literature, and there are currently no clear diagnostic criteria available. The aim of this study is to improve the diagnosis of musculo-articular contractures of the lower jaw by utilizing a comprehensive approach that includes clinical, radiological, and functional research methods. Materials and Methods. 25 patients

Abstract:

The temporomandibular joint is paired, a complex formation of an ellipsoid shape, which is formed by the articular head of the lower jaw, the mandibular fossa and the articular tubercle of the temporal bone, covered with fibrous cartilage. There are two types of movements in the temporomandibular joint: translation and rotation, which implement protrusion-retrusion, right and left mediotrusion, and opening-closing. Computerized axiography is used for assessment of the mandibular movements and the patient’s skeletal parameters. This type of examination allows you to adjust the articulator for a

The SUP behaved like a jaw-closing muscle and showed characteristic activity in relation to the biting force.

This article reviews the assessment of interalveolar height deficit in morphometric comparison with its projection onto the superior space of the temporomandibular joint (TMJ) using cone-beam computed tomography (CT) of the TMJ. The technique for calculating the gaps between the fossa and the head, determining the coefficients for their comparison, and their correlation with clinical signs of TMJ dysfunction in occlusal and articulatory disorders is described. The aim - to determine CT diagnostic criteria for decreased interalveolar height in patients with functional TMJ disorders with occlusa

Abstract:

In this review, the movement characteristics of the human masticatory system are discussed from a biomechanical perspective. The discussion is based upon the three fundamental laws of mechanics applied to the various anatomical structures that are part of the masticatory system. An analysis of the forces and torques applied to the mandible by muscles, joints, articular capsules, and teeth is used to assess the determinants of jaw movement. The principle of relating the interplay of forces to the center of gravity of the lower jaw, in contrast to a hinge axis near its joints, is introduced. It

Introduction. Facial asymmetries associated with lateral displacement of the jaw arise due to various reasons, namely, the presence of functional lateral displacement of the lower jaw, skeletal asymmetry of the maxillofacial region, and a combination of the above factors. Purpose. Identification of the etiological factor makes it possible to assess the possibility of correcting the position of the lower jaw and improving the relationship of the intra-articular structures of the temporomandibular joint. Materials and methods.

The basic kinematic feeding sequence observed in other aquatic-feeding lower vertebrates is conserved in the spiny dogfish. Prey capture, bite manipulation and suction transport eve

Abstract The jaw articulation of most endemic New World jays (Corvidae) has a condyle of the quadrate and an opposing cotyla of the lower jaw not found in other birds. They also have well-developed meatic articular facets of the quadrate and cranium. The tip of the rhamphotheca of the lower mandible is chisel shaped. These and other features constitute a functional unit, the buttress complex, that braces the partially opened lower jaw and enhances its use as a chisel. The buttress complex stabilizes the lower jaw by anchoring the jaw on the quadrate and reducing torque on the quadrate during p

A higher level of prognatism of the lower jaw in relation to the upper one can be the consequence of its excessive length. The aim of this study was to find the differences in the length of the lower jaw in the children with skeletal class III and the children with normal sagital interjaw relation (skeletal class I) in the period of mixed dentition.
