Abstract
Introduction: According to the scientific literature, sleep bruxism (SB) could produce orofacial muscle, dental, and temporary headaches as well as postural alterations. Objective: To evaluate the stomatognathic system and the posture of an individual diagnosed with sleep bruxism (SB) from an interdisciplinary approach. Materials and methods: Descriptive study of a case report of a female individual. The SB was determined by polysomnography. Static and dynamic inter-occlusal relationships were analyzed by assembling models in a semi-adjustable articulator. An orofacial evaluation was performed by applying myoscanoplasty, dynamometry, and electromyography, and an evaluation of postural alignment and stability was performed using the Romberg index and plantar pressures with baropodometry. Results: In the polysomnography, 132 minutes of MOR stage and 265 of NMOR, 56 events of SB / hour, 86 micro-awakenings, 11 hypopneas, a cardiac rate of 67 l / min, and an oximetry of 95% were recorded. In the mastication, there was activity marked in masseters (Right: 330 uV Left: 452 uV) and temporary Right: 418 uV and asymmetry of temporal (34%) and orbicular (33%). There was a decrease in the contractile force of the masseter (0.3 lb) and compressive force of the orbicular (2.0 lb). Myositis was registered in the orofacial and neck muscles. There was postural involvement of left hemibody, stability during static bipedal position with Romberg Index of 0.99, and greater plantar pressure in the left foot of 68.5% than in the right foot of 31.5.Conclusions: In a case of SB diagnosed by polysomnography, there were alterations of the stomatognathic system at the dental, TMJ, and muscular levels with postural alterations and plantar pressure.
