description Objectives: Studies involving electrognathographic (EGN) recordings of chewing improvements obtained following occlusal adjustment therapy are rare, as most studies lack 'chewing' within the research. The objectives of this study were to determine if reducing long Disclusion Time to short Disclusion Time with the immediate complete anterior guidance development (ICAGD) coronoplasty in symptomatic subjects altered their average chewing pattern (ACP) and their muscle function. Methods: Twenty-nine muscularly symptomatic subjects underwent simultaneous EMG and EGN recordings of right and left gum chewing, before and after the ICAGD coronoplasty. Statistical differences in the mean Disclusion Time, the mean muscle contraction cycle, and the mean ACP resultant from ICAGD underwent the Student's paired t-test (α = 0.05). Results: Disclusion Time reductions from ICAGD were significant (2.11-0.45 s. p = 0.0000). Post-ICAGD muscle changes were significant in the mean area (p = 0.000001), the peak amplitude (p = 0.00005), the time to peak contraction (p

Post-ICAGD ACP changes were also significant; the terminal chewing position became closer to centric occlusion (p < 0.002), the maximum and average chewing velocities increased (p < 0.002; p < 0.00005), the opening and closing times, the cycle time, and the occlusal contact time all decreased (p < 0.004-0.0001). Conclusion: The average chewing pattern (ACP) shape, speed, consistency, muscular coordination, and vertical opening improvements can be significantly improved in muscularly dysfunctional TMD patients within one week's time of undergoing the ICAGD enameloplasty. Computer-measured and guided occlusal adjustments quickly and physiologically improved chewing, without requiring the patients to wear pre- or post-treatment appliances.]]></description><identifier>ISSN: 0886-9634</identifier><identifier>EISSN: 2151-0903</identifier><identifier>DOI: 10.1080/08869634.2016.1190526</identifier><identifier>PMID: 27332882</identifier><language>eng</language><publisher>England: Taylor &amp; Francis</publisher><subject>Average chewing pattern (ACP) ; Dental Occlusion, Balanced ; Dental Stress Analysis - methods ; Dentistry ; Disclusion Time Reduction ; Electrodiagnosis - methods ; Electrognathography (EGN) ; Electromyography (EMG) ; Electromyography - methods ; Humans ; ICAGD coronoplasty ; ICAGD enameloplasty ; Malocclusion - physiopathology ; Malocclusion - therapy ; Mastication - physiology ; Masticatory Muscles - physiopathology ; Muscle Contraction ; Occlusal Adjustment - methods ; Signal Processing, Computer-Assisted ; T-Scan</subject><ispartof>Cranio, 2017-05, Vol.35 (3), p.135-151</ispartof><rights>2016 Informa UK Limited, trading as Taylor &amp; Francis Group 2016</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c366t-a3ed55b4a4fab88f3e912bd8f5f24116dfec09166c138a39de5313b0834c60753</citedby><cites>FETCH-LOGICAL-c366t-a3ed55b4a4fab88f3e912bd8f5f24116dfec09166c138a39de5313b0834c60753</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/27332882$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Kerstein, Robert B.</creatorcontrib><creatorcontrib>Radke, John</creatorcontrib><title>Average chewing pattern improvements following Disclusion Time reduction</title><title>Cranio</title><addtitle>Cranio</addtitle><description><![CDATA[Objectives: Studies involving electrognathographic (EGN) recordings of chewing improvements obtained following occlusal adjustment therapy are rare, as most studies lack 'chewing' within the research.
