1/139. temporomandibular joint ankylosis: review of thirty-two cases.I have reviewed aetiology, sex, age at time of treatment, clinical features, radiographic findings, anaesthetic techniques, surgical treatment, complications, and results in 32 patients with ankylosis of the temporomandibular joint. Trauma and infection were the commonest causes of ankylosis: 50% and 41%, (n = 13), respectively. The 21-30 year age group had the most trauma cases. Twenty (63%) of the patients presented with bilateral ankylosis. Failing to do jaw-opening exercises was the main cause of relapse.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
2/139. Long-term stability of mandibular orthopedic repositioning.Mandibular anterior repositioning appliances attempt to diminish temporomandibular joint pain, soft tissue noise, and myofascial discomfort by altering condyle-disc relationships. Secondary stabilization of the occlusion to this arbitrary anterior position through orthodontic tooth movement may significantly alter functional and muscular relationships. A case report is illustrated to show that as the functional environment attempted to reestablish equilibrium through adaptation, relapse occurred as the condyles "seated" posteriorly and superiorly toward their original relationship within the fossa. For all practical purposes, complete relapse of the orthodontic treatment result took place over time.- - - - - - - - - - ranking = 0.049705384119936keywords = relation (Clic here for more details about this article) |
3/139. Rheumatoid arthritis-affected temporomandibular joint pain analgesia by linear polarized near infrared irradiation.PURPOSE: To describe a new short-term treatment for pain in rheumatoid arthritis (RA)-affected temporomandibular joint (TMJ). CLINICAL FEATURES: We investigated four female patients (age 42.8 /-26.0 yr) with chronic rheumatoid arthritis affecting a single TMJ. patients had received antirheumatic drugs such as sodium aurothiomalate, and as a result showed no symptoms in other body joints. Linear polarized near infrared radiation using Super Lizer was applied weekly with and/or without jaw movement to the unilateral skin areas overlying the mandibular fossa, anterior articular tubercle, masseter muscle and posterior margin of the ramus of the mandible. The duration of irradiation to each point was two seconds on and ten seconds off per cycle and the intensity at each point was approximately 138 J x cm(-2) at a wavelength of 830 nm. Interincisal distance was measured with maximal mouth opening in the absence and presence of pain before and after each treatment. Additionally, subjective TMJ pain scores assessed using a visual analog scale were performed for painful maximal mouth opening before and after each irradiation. TMJ pain disappeared after only four treatments. Moreover, painless maximal mouth opening without pain after irradiation in three patients was on average improved to 5.3 /-2.1 mm. However, one case was observed where the opening length prior to irradiation did not improve, despite the fact that the RA-affected TMJ pain had disappeared. CONCLUSION: Application of linear polarized near infrared irradiation to patients with RA-affected TMJ pain is an effective and non-invasive short-term treatment.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
4/139. Idiopathic condylar resorption: diagnosis, treatment protocol, and outcomes.Idiopathic condylar resorption is a poorly understood progressive disease that affects the TMJ and that can result in malocclusion, facial disfigurement, TMJ dysfunction, and pain. This article presents the diagnostic criteria for idiopathic condylar resorption and a new treatment protocol for management of this pathologic condition. Idiopathic condylar resorption most often occurs in teenage girls but can occur at any age, although rarely over the age of 40 years. These patients have a common facial morphology including: (1) high occlusal and mandibular plane angles, (2) progressively retruding mandible, and (3) Class II occlusion with or without open bite. Imaging usually demonstrates small resorbing condyles and TMJ articular disk dislocations. A specific treatment protocol has been developed to treat this condition that includes: (1) removal of hyperplastic synovial and bilaminar tissue; (2) disk repositioning and ligament repair; and (3) indicated orthognathic surgery to correct the functional and esthetic facial deformity. patients with this condition respond well to the treatment protocol presented herein with elimination of the disease process. Two cases are presented to demonstrate this treatment protocol and outcomes that can be achieved. Idiopathic condylar resorption is a progressive disease that can be eliminated with the appropriate treatment protocol.- - - - - - - - - - ranking = 0.93331769121412keywords = bite (Clic here for more details about this article) |
5/139. Metastatic cancer presenting as TMD. A case report.The dentist's responsibility in managing patients should include the awareness that not every pain in the face is due to a toothache or a temporomandibular disorder (TMD). This paper reviews the case of a 66-year-old patient who presented to the dental office with a chief complaint of unilateral jaw pain. The symptoms seemed consistent with TMD. Two years prior, the patient had undergone successful removal of a cancerous prostate and had remained under urologist care with a favorable prognosis. Subsequent imaging studies confirmed that the facial pain was due to multiple metastatic lesions to areas including the zygoma, infratemporal fossa, maxilla and brain. However, these metastatic lesions were not of prostate origin, but rather were from a squamous cell carcinoma originating in a primary site other than the prostate.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
6/139. Condylar resorption 2 years following active orthodontic treatment: a case report.We recently treated a patient with degenerative disease of the temporomandibular joint. A healthy, 12-year-old female with bilateral high maxillary canines presented for orthodontic treatment. Two years after active orthodontic treatment, at age 17, symptoms in her temporomandibular joint manifested and progressed. By the time she revisited our hospital at age 21, the patient had developed an anterior open bite with a long, slender facial appearance. Cephalometric analysis showed shortening of the ramus and backward and downward rotation of the mandible. Imaging studies revealed severe deformity and resorption of the bilateral condyles. Her occlusal and morphologic changes seemed to be caused by degenerative disease of the temporomandibular joint.- - - - - - - - - - ranking = 0.93331769121412keywords = bite (Clic here for more details about this article) |
7/139. Worsening of pre-existing TMJ dysfunction following sagittal split osteotomy: a study of three cases.When patients seeking treatment for malocclusion also suffer from temporomandibular joint (TMJ) disorders, it is hard to predict the result of simultaneous treatment of both conditions, or to plan for its different goals, because of unpredictable changes in the relationship between the disk, the fossa and the condylar head. Prediction is harder in cases of presurgical TMJ hypomobility, especially those with adhesion in the upper TMJ compartment. Authors differ widely on the likely effect of orthognathic surgery on TMJ disorders. This paper reports three cases in which TMJ disorders worsened after treatment of malocclusion by sagittal split osteotomy. It examines how presurgical diagnosis of TMJ disorders could assist treatment planning in such cases. The results suggest that microbleeding in the upper TMJ compartment during orthognathic surgery, as well as long-term postoperative intermaxillary fixation, carries a risk of creating worse adhesion that adversely affects the outcome for patients. Therefore, preoperative diagnosis of disk position and pathological conditions in the upper TMJ compartment, as well as careful choice of method and term of postoperative fixation, are essential in planning the treatment of malocclusion with sagittal split osteotomy.- - - - - - - - - - ranking = 0.016568461373312keywords = relation (Clic here for more details about this article) |
8/139. Nonsurgical and nonextraction treatment of skeletal Class III open bite: its long-term stability.Two female patients, aged 14 years 5 months and 17 years 3 months with skeletal Class III open bite and temporomandibular dysfunction are presented. They had previously been classified as orthognathic surgical cases, involving first premolar removal. The primary treatment objective was to eliminate those skeletal and neuromuscular factors that were dominant in establishing their malocclusions. These included abnormal behavior of the tongue with short labial and lingual frenula, bilateral imbalance of chewing muscles, a partially blocked nasopharyngeal airway causing extrusion of the molars, with rotation of the mandible and narrowing of the maxillary arch. Resultant occlusal interference caused the mandible to shift to one side, which in turn produced the abnormal occlusal plane and curve of Spee. As a result, the form and function of the joints were adversely affected by the structural and functional asymmetry. These cases were treated by expanding the maxillary arch, which brought the maxilla downward and forward. The mandible moved downward and backward, with a slight increase in anterior facial height. Intruding and uprighting the posterior teeth, combined with a maxillary protraction, reconstructed the occlusal plane. A favorable perioral environment was created with widened tongue space in order to produce an adequate airway. myofunctional therapy after lingual and labial frenectomy was assisted by vigorous gum chewing during and after treatment, together with a tooth positioner. Normal nasal breathing was achieved.- - - - - - - - - - ranking = 4.6665884560706keywords = bite (Clic here for more details about this article) |
9/139. Surgical orthodontic treatment of skeletal Class III malocclusion with anterior disc displacement without reduction (ADNR): a case report.A female patient with skeletal problems and left temporomandibular joint (TMJ) derangement was treated with an occlusal splint, arthroscopic irrigation, and orthodontic surgery. The left side disc was displaced anteriorly without reduction; and mobility of the left condylar head was restricted. With arthroscopic irrigation, the jaw functions were recovered, but the disc position remained the same. After TMJ therapy, orthodontic and orthognatic surgery treatments were performed to correct the dentofacial deformity. Stable facial esthetics and occlusion devoid of temporomandibular joint disorder (TMD) symptoms were obtained and the patient's progress was monitored over a 5-year period.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
10/139. Complex orthodontic problems: the orthognathic patient with temporomandibular disorders.The diagnosis and treatment of temporomandibular disorders (TMD) remain controversial despite considerable research and publication in this area. The relationship of these problems to dental and skeletal malocclusion is equally debatable. Recent studies suggest that although malocclusion may have a role, it is a small one. Accordingly, treatment of TMD with occlusion-altering therapy, such as orthodontics and orthognathic surgery, should be limited to specific situations. This report discusses the management of patients with coexisting TMD and skeletal malocclusion. Current concepts in clinical and radiographic diagnosis are discussed, as well as an overview of noninvasive therapy. A case report is used to illustrate an approach to diagnosis and treatment planning in an individual with active TMD and a skeletal malocclusion requiring orthognathic surgery for correction.- - - - - - - - - - ranking = 0.016568461373312keywords = relation (Clic here for more details about this article) |
