Electromyographic and computer analyses of patients suffering from chronic myofascial pain-dysfunction syndrome: Before and after treatment with immediate complete anterior guidance development

Assessment of masticatory muscle activity and occlusion time in patients with advanced tooth wear

“…Patients with advanced tooth wear revealed lower mean activity of their elevator muscles during maximal clench compared to controls. Additionally, mean 20,21 However, the differences between individuals should be taken into account. It is known that the results obtained during an examination performed to assess the magnitude of maximum voluntary occlusal force might be lower than a true maximum when the patient is afraid of breaking fillings or teeth that are recently already damaged or that might lead to damage.…”

“…Occlusion time from the first tooth contact to maximum intercuspation at maximal voluntary clench was measured to describe the closing event. 21 The T-Scan sensor (thickness 100 mm AE 1.0 uncompressed) was placed intraorally with the point of the support properly at the central incisors prior to recording. Subjects were instructed to close their teeth maximally together for 3-5 s and then open and repeat the MVC clench 2 more times.…”

Condylar Position Indicator and T-Scan system II in clinical evaluation of temporomandibular intracapsular disease

“…Many studies have shown how T-Scan force records were supported by surface electromyography. A direct correlation seems to exist between contractile muscle activity and occlusal interference (Kerstein and Wright, 1991).…”

An oral rehabilitation robot for massaging the masseter and temporal muscles: a preliminary report

“…5 VAS scores for the massage. In the dose-escalation study, the healthy volunteers were massaged at three different pressures: 1-2, 6-8, and 10 N. The figure shows box-and-whisker plots of the VAS scores for comfort, warmth, and ease of mouth opening after massage stress, and imbalance of the masticatory muscles [2][3][4][5]20]. Of these, involuntary alteration of the activity of one or more muscles can produce an imbalance in the mechanism of mouth opening and closing and cause symptoms such as cervical pain, headaches, earaches, clicking, disk degeneration, breaking, and lateral deviation of the mandible [21].…”
