Influence of different narrative instructions to record the occlusal contact with silicone registration materials

Abstract: This study examined the influence of narrative instructions on the occlusal contact area, occlusal contact point and masticatory muscle activities in normal subjects. Twelve healthy men and 12 healthy women with no more than one missing tooth per quadrant participated. Surface EMG was recorded from the masseter and temporal muscle. As a control measurement, intercuspal position was maintained to produce a habitual clenching record (NCR) while the occlusal contact area and occlusal contact point was recorded by… Show more

“…We have shown that registration of occlusal contact during intercuspation using silicone material was not stable at 10% maximum voluntary contraction (MVC), but was stable at 20% MVC and continued to be at 40% MVC . Therefore, adequate clenching force may be required to register the appropriate occlusal contact, and proper verbal instructions would help to take a stable occlusal recording of the natural dentition . On the other hand, as there is multidirectional visibility and possible simulation for occlusal treatment, occlusal examination is also performed using an articulator with dental arch casts .…”

“…First, participants were not instructed in exerting occlusal force using visual feedback electromyography, so the OCA varied depending on inter-individual occlusal force 22,24,25) . To mitigate this problem, participants were instructed to clench their jaw for 1.5 minutes 26) on two occasions, and the record with more OCPs was analysed. Second, the presence of sleep behaviour cannot be confirmed by self-reporting because the participants cannot observe themselves when unconscious.…”

“…Zusätzlich wurde auch auf eine Positionierung des Kopfes in der Vertikalebene geachtet, da signifikante Veränderungen der sagittalen Kondylusposition bei vertikalen Kopfpositionen abseits der Frankfurter-Horizontal-Ebene festgestellt wurden (Ohmure et al 2008;Preiskel 1965;Visscher et al 2000). Wie bereits vorgestellt, spielten Konzentration (Berry und Wilmot 1977;Yemm 1969) , Vigilanz (Berry und Singh 1983), Motivation und Tonus (Gurdsapsri et al 2000;Hidaka et al 1999;Imamura et al 2015;Nishimori et al 2017;Obara et al 2014;Riise und Ericsson 1983;Tzakis et al 1992) Anwendung limitierte (Anderson et al 1993;Gazit et al 1986;Reiber et al 1989).…”

“…In diesem Zusammenhang wurde ebenfalls die Anfälligkeit der Registrierung, auf leichte Aufbisskräfte mit fehlender Perforation des Materials zu reagieren, beschrieben (Millstein 1985;Millstein et al 1973). Zusätzlich beschrieben Millstein (1985) und Michalakis et al (2004) (Hützen et al 2006;Obara et al 2014;Obara et al 2013) hätten zur Objektivierbarkeit der Befunde beigetragen, jedoch nicht die fraglichen und untersuchungsabhängigen Materialeigenschaften der Registrierung kompensieren können. Die Ergebnisse der durchgeführten Wachsregistrierung sind damit zusammenfassend kritisch zu hinterfragen und vor allem unter dem Aspekt eine Tageszeitabhängigkeit nachzuweisen, als wenig reliabel einzuordnen (Kordaß und Lovrov 2013;Michalakis et al 2004;Millstein 1985;Millstein et al 1973;Qadeer 2017;Yu und Lee 2010).…”
