Abstract
Displacement of the non-reduction disk with limitation of opening (DDwLO) can be treatment of the non-surgical form. However, it required scientific and clinic knowledge of diagnostic area of the disorders temporomandibulares. This study was performed with the patient CN, 18 years, white, female, who went to the orofacial pain ambulatory with complaints of extreme pain on the right temporomandibular joint (TMJ) and limitation of maximum opening of 29 mm with shift to right, which she has been suffering for at least three years. After a criterion anamnese the diagnosis hypothesis found was a displacement of the non-reduction disk with limitation of opening. The treatment was based on infiltration in the right TMJ with anesthesic followed by mandibular manipulation. After the therapeutic conduct the patient presented clinical signals of normality with absence of trismus and mandibular movement without shift to right. The patient was followed up during five years not presenting return of the pathology.
Highlights
IntroductionAbnormal position of the articular disc on the mandibular condyle and articular eminence [1]
The term usually denotes a disk displacement (DD)abnormal position of the articular disc on the mandibular condyle and articular eminence [1].The temporomandibular joint disorders develop an important role in the production of signs and symptoms such as clicks, pain, crepitation, and locking jaw or mandibular trismus which has been widely discussed in the literature
The author suggests that studies addressing the pathogenesis of DD should start with an improvement in the understanding of the mechanism of temporomandibular joint (TMJ) by synovial fluid lubrication and its decrease
Summary
Abnormal position of the articular disc on the mandibular condyle and articular eminence [1]. The temporomandibular joint disorders develop an important role in the production of signs and symptoms such as clicks, pain, crepitation, and locking jaw or mandibular trismus which has been widely discussed in the literature. Its pathogenesis remains without evidence, the second Manfredine D [2] the morphological role (occlusal abnormalities and slope of the articular eminence) and functional factors (muscle hyperactivity side pterigoideo) seem to be much less important than reported in the past. According to a study of the prevalence temporomandibular disorders (TMD) the authors detected that 8% of the diagnosed cases involved only TMJ, 73% involved only the masticatory muscles and 19% had the two disturbance forms. According to this study researchers about 8 million Brazilian have some degrees of TMD 90% of its total are women aged between 20 and 45 years [3]
