RESUMEN
Introducción: con la finalidad de contrastar la hipótesis nula no existen diferencias significativas en lascaracterísticas arquitecturales y estructurales craneofaciales entre individuos con y sin desgaste dentario se realizó un estudio analítico, no experimental de casos y controles en pacientes que consultaron por tratamiento prostodóncico u ortodóncico. Métodos: la muestra quedó conformada por 26 pacientes con desgate dentario severo (estudio) y 52 pacientes sin desgaste dentario (control).El grupo control se obtuvo por pareamiento según sexo, rango de edad y ángulo de la base de cráneo. Todos ellos poseían estabilidad oclusal y no presentaban tratamiento ortodóncico previo, procedimientos quirúrgicos maxilofaciales ni patologías de crecimiento y desarrollo. Se utilizó un cefalograma específicamente diseñado que incluyó los parámetros arquitecturales y estructurales delanálisis de Delaire. Para el análisis de los datos fueron utilizados el t Test y el Chi cuadrado dependiendo de la naturaleza de los datos. Resultados: diferencias significativas fueron encontradas particularmente a nivel del hueso basal maxilar y mandibular y en la posición del plano oclusal real respecto al plano oclusal teórico. Conclusiones: se concluyó que en pacientes con desgaste dentario severo, se produce una modificación del hueso basal y mandibular por remodelación del proceso dentoalveolar que resulta en una rotación craneal del plano oclusal. Se observa aparente estabilidad de la altura facial y del ángulo mandibular a pesar del cambio obvio de la posición del plano oclusal.
ABSTRACT
Introduction: in order to test the null hypothesis there are no significant differences in the craniofacial architectural and structural characteristics among individuals with and without severe tooth wear, a non experimental analytic case controlstudy was carried out with patients who consulted for prosthodontic or orthodontic treatment. Methods: 78 patients between 22 and 55 years of age participated. The experimental group consisted of 26 patients between 29 and 55 years of age (9 women and17 men). The control group consisted of 52 patients between 22 and 50 years of age (18 women and 34 men) matched by gender age range and posterior cranium base angle. All of them had occlusal stability, without previous orthodontic treatment, surgeryor growth and development alterations. The measuring instrument was a specifically designed cephalogram which included the architectural and structural parameters from Delaires Analysis, combined with some extra radiographic points defined by the authors for this particular study. The parameters under investigation were different cranial structural relationships includingocclusal plane position. Statistical analysis using t-test, Chi square test and Pearsons correlation test were carried out depending of the nature of the data. Results: significant differences were particularly found on maxillary and mandibular basal bone and on the position of the actual occlusal plane with respect to the theoretical plane. Conclusions: it was concluded that in patients with severe tooth wear, a modification of the maxillary and mandibular basal bone could have taken place with remodelling of the dental alveolar process resulting in a cranial rotation of the occlusal plane. An apparent stability of the facial height and the mandibular angle was observed in spite of the obvious change in the position of the occlusal plane.
