“…In addition, this study's results corroborate the findings of previous disclusion time reduction studies involving the ICAGD coronoplasty as a treatment for myofascial pain symptoms. [17181920212223] The role of occlusion in activating myofascial pain symptoms has long been debated. While some authors have shown occlusal equilibration to be a successful treatment modality in treatment of such disorders[567], other controlled studies have shown there were similar symptom resolutions in both the control and the treated groups.…”

“…[17181920212223] Shortening the disclusion time can be accomplished with the immediate complete anterior guidance development (ICAGD) enameloplasty or by an additional procedure performed with the aid of computerized occlusal analysis (T-Scan III, Tekscan Inc., S. Boston, MA, USA) that records real-time measurements of excursive movements as dynamic force movies. [17]…”

Purpose:The purpose of this study is to evaluate the longevity of reduced disclusion time in treating and removing myofascial pain dysfunction symptoms following the T-Scan-based, immediate complete anterior guidance development (ICAGD) coronoplasty. This measured occlusal adjustment has been shown to reduce the muscle hyperactivity of myofascial pain.Methods:Myofascial pain symptomatic patients were recruited as per the diagnostic criteria for temporomandibular disorders (TMDs), including the clinical protocol and assessment instruments outlined by the international RDC/TMD consortium network (version: January 20, 2014) to assess the efficacy of reduced disclusion time in left and right lateral excursions to resolve the myofascial pain symptoms. As per the inclusion and exclusion criteria, 100 cases were treated with ICAGD in three visits, each 1 week apart. Recall disclusion time measurements were recorded every 3 months over 3 years. The RDC/TMD questionnaire was used for symptom assessment at every recall visit. ICAGD brought pretreatment prolonged disclusion time down to <0.4 s, as quantified from T-Scan force and time data records, while the subjects were assessed for symptom relief. The Wilcoxon signed-rank test was used for statistical analysis (P < 0.05).Results:Changes in the intensity of many symptoms from reducing the disclusion time to <0.4 s were statistically significant from treatment day 1, and onward through the 3-year period of observation (P < 0.05).Conclusion:The results indicate that ICAGD reduces the musculoskeletal symptoms of myofascial pain, such that this methodology increases clinical therapeutic success.

“…Dental occlusion varies among individuals according to the size, shape, and position of the teeth; timing and sequence of eruption; dental arch size; and shape and pattern of craniofacial growth 4 . The position of the teeth within the jaw and the mode of occlusion are determined by developmental processes that affect the teeth and their associated structures during the period of formation, growth, and post-natal modification 1–3 . Any anomaly occurring during or after developmental processes can result in maxillary and/or mandibular deformities 5, 6 .…”

Dental occlusion varies among individuals, and achieving correct physiological occlusion after osteotomy is essential for the complex functioning of the stomatognathic system. The T-Scan system records the centre of force, first contact, maximum bite force, and maximum intercuspation. The aim of the present study was to investigate the usefulness and consistency of T-Scan in assessing occlusion before and after orthognathic surgery. Occlusal information was evaluated for 30 healthy adults with normal occlusion and 40 patients undergoing orthognathic surgery. T-Scan had a high degree of reliability for consecutive measurements (Pearson correlation, r = 0.98). For most parameters, occlusal distribution was better after surgery than before surgery. More teeth contributed to occlusion at maximum intercuspation after surgery than before surgery (14 vs. 10). In addition, the difference in the posterior force distribution was reduced after surgery (17.6 ± 13.8 vs. 22.7 ± 21.4 before surgery), indicating better occlusal force distribution after surgery. The maximum percentage force on teeth (p = 0.004) and the number of teeth contributing to occlusion (p < 0.001) also differed significantly. Thus, T-Scan is good for assessing occlusal discrepancies and can be used to portray the pre- and post-operative occlusal contact distribution during treatment planning and follow-up.

Etiology and treatment of temporomandibular disorders (TMDs) have two schools of thought; one depends on the Axis I (physical/functional) and the other is on Axis II (biopsychosocial) as per the research diagnostic criteria for TMDs. TMDs are a group of musculoskeletal disorders affecting the structure and/or function of the temporomandibular joints (TMJ), masticatory muscles, dentition, and supporting structures.
