Resumen
Las interferencias mediotrusivas han sido por largo tiempo asociadas a la etiología de los trastornos temporomandibulares, sin embargo los contactos mediotrusivos no han sido adecuadamente diferenciados en su rol sobre estas patologías. Específicamente, la teoría del rol protector que jugarían los contactos mediotrusivos asistidos sobre las ATM, se evalúa en esta investigación. El propósito de este estudio es identificar el tipo de relación existente entre la presencia de contactos mediotrusivos asistidos y los signos y síntomas de trastornos intracapsulares, poniendo a prueba la teoría del rol protector atribuida a tales contactos Se examinaron 114 sujetos (58 hombres y 56 mujeres), con edades fluctuantes entre los 20 y 40 años (promedio 26,7 años con una desviación estándar de 5,65), los que fueron sometidos a una encuesta escrita que buscaba identificar antecedentes de signos y síntomas de TTM, al igual que condiciones sistémicas asociadas a estos trastornos. De los 114 sujetos, se excluyeron de la muestra 16 por presentar condiciones sistémicas asociadas al desarrollo de TTM, luego se sometieron a un examen extraoral en busca de ruidos, saltos y dolor articular, y a un examen intraoral que buscaba identificar la presencia de contactos mediotrusivos asistidos o no asistidos. Los resultados obtenidos mostraron una frecuencia y distribución de contactos mediotrusivos asistidos y no asistidos similares entre sí, y la presencia de los primeros se encontró asociada con la mayor frecuencia de signos de trastornos intracapsulares (p 0,001), lo que va en contra de la teoría protectora propuesta. Los contactos mediotrusivos asistidos jugarían un rol dañino sobre las ATM, contrario a lo propuesto según la teoría de su rol protector.
Mediotrusive interferences have being long time associated with the etiology of temporomandibular disorders, however, mediotrusive contacts have not being adequately differentiated in their roll over this pathologies. Specifically, the theory of the protective roll that this assisted mediotrusive contacts may play over the TMJ it's evaluated in this investigation The purpose of this study is to identify the kind of relation that exist between the presence of assisted mediotrusive contacts and the signs and symptoms of internal derangements, testing the theory of the protective roll attributed to such contacts. 114 subjects were examinated (58 men and 56 women), with fluctuating ages between 20 and 40 years (average 26.7 years, with a standard deviation of 5.65), were submitted to a written survey that looked to identify backgrounds on signs and symptoms of TMD, as to systemic conditions that where associated with this disorders. Of the total 114 subjects, 16 where excluded from the sample for presenting systemic conditions associated to the development of TMD, then the rest of the subjects where submitted to an extraoral examination in search of articular sounds, jumps or pain, and an intraoral examination that looked to identify the presence of assisted mediotrusive contacts or non-assisted mediotrusive contacts. The results obtained show a frequency and distribution of the assisted and non-assisted mediotrusive contacts similar among them, and these first where statistically associated with a larger frequency of sings of internal derangements (p 0,001), which goes against the proposed protective theory. Assisted mediotrusive contacts would play a harmful roll over the TMJ, against the proposed according to the protective roll theory.
