In order to study the modifying effects of functional appliances on the mechanical environment of the temporomandibular joint (TMJ), we characterised the structure of the mandibular condyle subsequent to an experimental functional appliance intervention. Eight, four-month-old, castrated male Merino sheep, were randomly allocated to experimental and control groups (n = 4 in each group). Forward ...

The articular disc in the temporomandibular joint plays an important role in mandibular growth. Functional appliances induce regeneration of the condyle even after condylectomy. The aim of this study was to examine the role of the articular disc in regeneration of the condyle after unilateral condylectomy with use of a functional appliance in growing rats. Fifty growing rats were subjected to u...

Computed tomography (CT) has been increasingly used in the examination of patients with craniofacial trauma. This technique is useful in the examination of the temporomandibular joint and allows the diagnosis of fractures of the mandibular condyle. Aiming to verify whether the three-dimensional reconstructed images from CT (3D-CT) produce more effective visual information than the two-dimension...

OBJECTIVE The aim of the present study was to clarify the effects of a liquid diet on the temporomandibular joint (TMJ) in growing rats. MATERIALS AND METHODS Twenty-four male Wistar rats were weaned at 21 days and divided into control and experimental groups (12 in each group). Control rats were fed a solid diet and experimental rats were fed a liquid diet from 1 to 8 weeks. After injection ...

Previous studies have indicated that an injured condyle during adolescence is a causative factor for reduced mandibular growth and resulting asymmetry of the mandible. The aim of this study was to examine the nature of mandibular growth after unilateral condylectomy and to elucidate the effects of mandibular advancement. Sixty growing mice were subjected to unilateral condylectomy, and then one...

AIM The intent of this report is to present a brief review of the literature on osteochondroma and to present a case involving the surgical removal and replacement of a major portion of the condyle and angle of the mandible using free autogenous mandibular bone. BACKGROUND While osteochondroma is the most common tumor of skeletal bones, it is relatively uncommon in the jaws occurring at the c...

The pattern of mineralization was studied in the mandibular condyle of the young adult rat. Specimens were rendered anorganic in NaOC1 and examined in a scanning electron microscope. A mineralized cartilage front was found to persist on the articular aspect of the condyle. The surface is characterized by closely approximating chondrocyte lacunae enclosed to different degrees within the minerali...

Tongue enlargement and mandibular prognathism are clinically recognized in almost all patients with acromegaly. An acromegaly-like rat model recently developed by exogenous administration of insulin-like growth factor I (IGF-I) was used to investigate morphological and histopathological changes in orofacial structures and to clarify whether these changes were reversible. Exogenous administratio...

Rare occurrence and often misdiagnosed clinically ,we report a case of 42 year old male patient with very unusual diagnosis of superolateral dislocation of intact mandibular condyle bilaterally following traumatic insult to the mandible. Diffuse edema in the chin area and a left lateral deflection of the mandible, including an open bite and a crepitation in the Right parasymphyseal region. Thre...

Introduction: Mandibular fractures are the most common facial affecting various anatomical sites of mandible. Among mandibular fractures, management condylar remains a challenging task for surgeons. Case Report: We report case 28 year old male patient who presented with pain in chin and restricted mouth opening. Computed tomography revealed sagittal fracture right head medial displacement fract...
