“…TMJ imaging, per formed within 1 year in most of those patients, showed disk displacement in 87% of the joints and effusion, inflammation, or edema in the retrodiskal tissue in 80% of the joints. This prevalence of disk displacement in patients with TMJ-related symptoms agrees well with the MR imaging findings of 77% and 82% disk displacement in two studies [16,17] of patients referred for MR imaging of their TMJs but with no specific history of whiplash trauma. The results ofthe study by Garcia and Arrington cannot therefore be interpreted as showing a re lationship between whiplash trauma and the de velopmentof disk displacement but, rather, confirma highprevalence of diskdisplacement in patients with TMJ symptoms.…”

OBJECTIVE. Thepurpose of thisstudywastodescribe theincidence of temporomandibularjoint (TMJ) changes after a well-defined whiplash trauma. SUBJECTSAND METHODS. Sixtyconsecutively admitted patients withsymptoms inthe neck after rear-end traffic collisions underwent MR imaging of the TMJs within 3â€"14 days after the collisions. Fifty-three healthy volunteers constituted a control group. RESULTS.No statistically significant differences werefoundbetween the60 patients andthe 53 volunteers regarding frequency, stage, grade, or direction of TMJ disk displacement or joint effusion.MR imaging revealedthat 45% of the controlgroup and 53% of the patient group had a displaced disk in one or both TMJs (p = .393). Disk displacement was seen in 35% ofTMJs in the control group and 40% ofTMJs in the patient group. Effusion was seen in 8% of TMJs in the control group and 6% of TMJs in the patient group. No signs of bleeding or edemain the softtissueswere observed. In 15% of the patients,mild clinical symptomsin the TMJ or masticatory muscles developed in association with the trauma; in one third of these patients the symptoms were transient. CONCLUSION. Thisprospective studydoesnotshowanysignificantly increased mcidence of disk displacement, joint effusion, or any other injury to the TMJ after whiplash trauma that could be revealed by MR imaging.

“…20,21,23,24 On the other hand, although there was no description regarding skeletal and occlusal patterns, MRI studies of symptom-free subjects have shown disc displacement in 33% of these subjects with clinically normal, undisturbed jaw function. 25,26 These results have led many authors to speculate that, in some instances, anterior disk displacement may be an anatomic variant or a precursor to TMJ dysfunction rather than a pathologic condition.…”

“…Katzberg, et al 14,15 observed a high prevalence of patients without symptoms who presented with disc displacements with and without reduction (33%). However, symptomatic patients are more frequently observed and represent up to 77% of the total amount of displacements.…”

RESUMO OCCLUSAL STABILIZATION APPLIANCE. EVALUATION OF ITS EFFICACY IN THE TREATMENT OF TEMPOROMANDIBULAR DISORDERS PLACAS ESTABILIZADORAS.AVALIAÇÃO DE SUA EFICÁCIA NO TRATAMENTO DAS DISFUNÇÕES TEMPOROMANDIBULAREScclusal stabilization appliances or splints are the most widely employed method for treatment of temporomandibular disorders (TMD). Magnetic Resonance Imaging (MRI) is the most indicated imaging modality to evaluate the components of the temporomandibular joint (TMJ). Forty patients with signs and symptoms of temporomandibular disorders were treated with splints for a mean period of 12 months, comprising regular semimonthly follow-ups. After stabilization of the clinical status, occlusal adjustments and MRI evaluation were performed. It was concluded that the success of this kind of treatment are related to the total (70%) or partial improvement (22.5%) of painful symptomatology and to the functional reestablishment of the craniomandibular complex. The MRI allowed evaluation and also the conclusion that the splints provide conditions for the organism to develop means to resist to the temporomandibular disorders by means of elimination of several etiologic factors. Moreover, after treatment the patients are able to cope with disc displacements with larger or smaller tolerance. Uniterms: Temporomandibular disorders; Occlusal stabilization appliance; Magnetic resonance imaging. placa estabilizadora é o mais difundido método de tratamento das disfunções têmporo-mandibulares. A Ressonância Magnética (RM) é o exame mais indicado para a visualização dos componentes da Articulação têmporo-mandibular (ATM). Quarenta pacientes com sinais e sintomas de disfunções têmporo-mandibulares foram tratados com as placas estabilizadoras por um período médio de 12 meses, com controles periódicos quinzenais. Após a estabilização do quadro clínico foram realizados ajustes oclusais e a avaliação por meio da RM. Concluímos que os melhores resultados dessa modalidade de tratamento são relacionados à melhora total (70%) ou parcial (22,5%) da sintomatologia dolorosa e ao restabelecimento da função do complexo crânio-mandibular. A RM permitiu avaliar e concluir que as placas possibilitam condições para que o organismo possa criar meios resistentes às disfunções da articulação têmporo-mandibular por meio da eliminação de vários fatores etiológicos. E que após o tratamento, os pacientes podem conviver com os deslocamentos do disco, alguns com maior, outros com menor tolerância.
