For many years, it has been considered necessary to restore posterior support with a bilateral free-end saddle when a full upper denture is opposed by a shortened dental arch. It was thought that this would provide occlusal stability and prevent anterior bite collapse and temporomandibular dysfunction. As free-end saddle partial dentures are often poorly tolerated by patients, this case study tests whether a retentive full-upper denture occluding with a shortened dental arch offers enough to fulfil a patient’s needs...

The oral and maxillofacial surgeon is instrumental in the management and care of pediatric patients with juvenile idiopathic arthritis (JIA) and should include JIA in the differential when evaluating pediatric patients with temporomandibular joint (TMJ) dysfunction. Medical management has largely decreased the need for surgical intervention, but these patients may require intraarticular steroid injections of the TMJ, close follow-up to monitor their facial growth, and management of the subsequent postinflammatory degenerative TMJ changes...

Mandibular growth is a complex process that involves the "functional matrix," an interaction of the muscles of mastication, occlusion, and jaw function. Although not a typical growth center, the mandibular condyle has a significant effect on the ultimate size, shape and function of the mandible and secondarily on overall facial form. Acquired temporomandibular joint (TMJ)/condylar abnormalities, such as juvenile idiopathic arthritis, idiopathic condylar resorption, TMJ ankylosis, and condylar hyperplasia, often result in facial deformity and functional deficits...

Congenital deformities of the temporomandibular joint (TMJ) complex can present as a heterogeneous continuum of growth disturbances of the mandibular condyle, articular eminence, and temporal bone. This article describes several syndromes with congenital condylar deformity, including mandibulofacial dysostosis (Treacher Collins syndrome), hemifacial microsomia, oculoauriculovertebral syndrome, oculomandibulodyscephaly (Hallermann-Streiff syndrome), and Nager syndrome. Variations in the extent of TMJ deficiency seen in each individual case influence the timing and techniques of TMJ reconstruction...

The incidence of tumors and pseudotumors of the temporomandibular joint (TMJ) in the pediatric population is low. They are often challenging to recognize unless associated with signs and symptoms that may erroneously be interpreted as TMJ dysfunction. Tumors of the TMJ can be divided into 3 categories based on the nature and type of precursor cell involved in the tumor: benign tumors, malignant tumors, and pseudotumors. This article discusses the most common entities in these categories.

Management of pediatric condylar fractures presents a unique challenge because the developing mandible provides limited available bone for fixation and primary teeth preclude the use of typical closed reduction techniques. The available literature is reviewed with regard to closed and open treatment approaches.

Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery...

Imaging of the temporomandibular joint in pediatric patients is a critical component in the evaluation and treatment of children with temporomandibular joint symptoms. MRI can provide detailed joint anatomy and identify inflammation, sometimes before symptom onset. Ultrasound scan is a convenient emerging modality to evaluate the joint and guide therapeutic injections. Radiography and computed tomography offer osseous detail to recognize early morphologic changes of the mandibular condyle and provide operative planning...

After a thorough review of the history and presentation of a child's facial pain, a targeted head and neck examination is critical to the appropriate diagnosis of facial pain and temporomandibular joint disorders. It is critical to distinguish between the structural (trauma, degenerative disease, and tumor) and nonstructural (neurogenic, myogenic, and psychological) causes of pain, which will allow for incorporation of appropriate strategies of medical, psychological, dental, and surgical therapies.

Cory M Resnick
Indications and considerations for reconstruction of the temporomandibular joint (TMJ) differ between growing and skeletally mature patients. Osteoarthritis, which is the most common cause of TMJ destruction in adults, is comparatively rare in children. The most common indications in young patients are congenital deformities, pathology, ankylosis and progressive resorptive processes. Options for reconstruction include distraction osteogenesis, autologous reconstruction (ie, costochondral graft, free fibula flap), and total alloplastic joint replacement...

This article focuses on the embryologic development and growth of the temporomandibular joint (TMJ) and touches on the development and growth of surrounding structures. Aberrations in structures surrounding the TMJ can affect its development as well. The normal adult anatomy of the TMJ is described as well as common malformations. The clinical ramifications of a malformed TMJ are also discussed in order to understand future necessary consultants involved in the care of these patients.

Synovial chondromatosis is a rare benign lesion originating from the synovial membrane. It presents as adhesive or non-adhesive intra-articular cartilaginous loose bodies. Although the causes of synovial chondromatosis have not been fully elucidated, inflammation, external injury, or excessive use of joints have been suggested as possible causes. Synovial chondromatosis has been reported to occur most frequently at large joints that bear weights, with a rare occurrence at the temporomandibular joint (TMJ). When synovial chondromatosis develops at TMJ, clinical symptoms, including pain, joint sounds, and mouth opening may common...

BACKGROUND: Most bone metastases are observed in the trunk of the body. Metastasis in the mandibular condyle is rare. In many case reports, temporary common temporomandibular joint disorder-like symptoms can be a sign of relapse and metastasis. CASE PRESENTATION: We report a rare case of breast carcinoma metastatic to the left mandibular condyle in a 55-year-old Japanese woman, who visited our department for a dental check-up prior to chemotherapy. She had almost no symptoms, but radiographs suggested the existence of metastasis...
