OBJECTIVES Research diagnostic criteria for temporomandibular disorders (RDC/TMDs) were proposed in 1992 with the aim of standardizing and testing methods for diagnosing TMDs. RDC/TMDs have so far been lacking standardized methods for imaging and criteria for imaging diagnosis of disorders of the temporomandibular joint (TMJ). Criteria for disorders of the TMJ have recently been proposed for MR...

Background. Anterior disc displacement without reduction of the temporomandibular joint (TMJ) is a relatively common finding, and generally, the treatment option for these patients involves surgery, which can include multiple procedures such as arthrocentesis, eminectomy, vertical subsigmoid osteotomy, or meniscopexy. Objective. The purpose of this study is to clinically evaluate the effectiven...

OBJECTIVE In order to understand the conflicting information on temporomandibular joint (TMJ) pathophysiologic responses after mandibular advancement surgery, an overview of the literature was proposed with a focus on certain risk factors. METHODS A literature search was carried out in the Cochrane, PubMed, Scopus and Web of Science databases in the period from January 1980 through March 2013...

This chapter describes the diagnostics of temporomandibular joint disorders (TMDs) with the main focus on the radiographic changes and the role of different bone markers as procollagen type I N-terminal propeptide (P1NP), C-telopeptide crosslaps of type I col‐ lagen (CTX-1) as well as vitamin D (25(OH)D) in the pathogenesis of TMDs. From our population-based study, 47% subjects had TMJ problems...

The three-dimensional configuration of the primate masticatory system is constrained by the need to maximize bite forces while avoiding distraction of the temporomandibular joint (TMJ). Within these bounds, shape variation has predictable effects on functional capacities such as mechanical advantage and gape. In this study, geometric morphometric analysis is used to investigate the ontogeny of ...

Background: Juvenile Idiopathic Arthritis-JIA is the most common inflammatory rheumatic disease during childhood, and affects Temporomandibular Joint-TMJ among other joints. TMJ arthritis can proceed without clinical signs and symptoms and remain undiagnosed, with detrimental effects on child's normal craniofacial growth and mandibular development. Aim: This review summarizes the current develo...

The temporomandibular joint (TMJ) is the most active, functioning joint of the body. Limitations of the mouth opening and deformity of the lower jaw can be caused by bony or fibrous ankylosis of the TMJ due to various reasons and mostly is due to fusion of the condyle to the base of the skull. Trauma to the TMJ is the most common etiology of ankylosis of TMJ. Clinical examination, radiographic ...

Objective of the study was to evaluate the clinical status of the masticatory system in young adults with full permanent dentition and no stomatognathic system complaints. The study involved 186 randomly selected people with full dental arches with normal occlusal conditions corresponding to Angle's Class I aged 18 - 21 years with an average age of 19 years. Subjects were clinically examined an...

Our previous study reported that inactivation of Shox2 led to dysplasia and ankylosis of the temporomandibular joint (TMJ), and that replacing Shox2 with human Shox partially rescued the phenotype with a prematurely worn out articular disc. However, the mechanisms of Shox2 activity in TMJ development remain to be elucidated. In this study, we investigated the molecular and cellular basis for th...

The most frequent intraarticular disorder of the temporomandibular joint (TMJ) represents the disorder of the functional relation between the articular disc and mandible condyle, i.e. dislocation of the articular disc. Magnetic resonance (MR) optimally visualizes the soft and hard articular tissues (articular disc, articular socket and condyle of the mandible) and its surroundings. The aim of t...
