We studied the influence of a dental occlusion perturbation on postural control. The tests were performed in three dental occlusion conditions: (Rest Position: no dental contact, Maximal Intercuspal Occlusion: maximal dental contact, and Thwarted Laterality Occlusion: simulation of a dental malocclusion) and four postural conditions: static (stable(More)
Impaction of the third molar is relatively frequent in oral and maxillofacial surgery, and its removal is a usual operation with mostly unremarkable outcome. We report a case of bleeding that occurred after a left upper third molar extraction, which necessitated in emergency an angiography with embolization.
OBJECTIVE The classic technique for open reduction of subcondylar fracture is the submandibular approach. The aim of this study was to evaluate long-term clinical and radiologic results of the short retromandibular approach to displaced subcondylar fractures. MATERIAL AND METHODS During a period of 66 months we performed a prospective study with a(More)
INTRODUCTION Limitation of mouth opening is a frequent symptom in the pathologies of the temporomandibular joint. The aim of this study is to establish normative basis for this criterion in the French population. MATERIALS AND METHODS Maximal mouth opening was measured by an electronic goniometric device. Measurements were taken in 228 people (110 men and(More)
A variety of interposition materials have been used to prevent recurrence after arthroplasty in treatment of temporomandibular joint ankylosis. The purpose of this retrospective study of our experience was to compare the different materials (skin, temporal muscle, homologous cartilage) used for interposition arthroplasty over a period of 22 years. A total(More)
Recurrence is a major problem after release of temporomandibular joint ankylosis. Early physiotherapy and choice of interpositional material are important in preventing recurrence. Currently, the most used technique is gap arthroplasty associated with coronoidectomy, temporalis muscle flap interposition and reconstruction of the condylar unit with a(More)
Posterior disk displacement is a rare temporomandibular joint (TMJ) disorder. The main clinical sign is sudden molar open-bite (jaw locked in the open position). This may be accompanied by a sensation of intra-articular foreign body and more rarely joint pain. Joint sounds are unremarkable. Mouth opening may be slightly impaired. Hypothetically, like(More)
We are yielding a case of recurring melanotic neuroectodermal tumor of infancy situated in the premaxilla, with a very quick evolution, haemorrhage, and which has precociously recurred after surgical removal. This tumor is studied on the paraclinical (CT scan, M.I.R.) and on the histological hand (immunohistochemical and ultra-microscopy). This observation(More)
AIM Fibular bone grafts are considered as one of the best choices for reconstruction of the condyle. However, little data are available on bone remodelling after such reconstruction. The purpose of this study was to evaluate the long-term radiological outcome. PATIENTS AND METHODS Eleven patients underwent condylar reconstruction with a free fibular(More)
