Functional characteristics of dento-facial relationships

Abstract

Introduction. Extent of exposure of the frontal teeth in the postural rest position is variable and is influenced by the dimensions and the position of the teeth, by the conformation of the dental arches, by fullness of lips and the facial muscular tonus. Studies oriented towards the perception of aesthetics in the field, have shown certain correlations in this regard. The aesthetic analysis of the dento-facial relationships in the smile includes other components such as the lip line of the smile, the negative space and the symmetry of the smile. The aesthetic examination methodology in all its complexity needs to be supplemented with the examination of the dento-maxillary and phonetic relationships. The way of pronouncing some sounds as well as the qualitative and quantitative values of the parameters of anterior guidance need to be evaluated and correlated with the aesthetic criteria, within the oral rehabilitation. Aim of the study. Development of a diagnostic procedure and treatment for functional disorders of the anterior group of teeth. Materials and methods.. Were examined and selected 7 patients between the ages of 30 and 55 years who showed signs of wear of the upper anterior group. The clinical and instrumental examination was completed with imaging methods and digital photography. The curative objectives followed the morphofunctional rehabilitation of the stomatognathic system. Results. Following the complex clinical examination, were determined the qualitative and quantitative parameters of the aesthetics, occlusion and phonetics. The complementary examinations confirmed some aspects of the existing morphofunctional disorders. The correlation of the values of the parameters listed above in the context of physiology, bio aesthetics and biomechanics served as an indication in the elaboration and realization of the complex treatment plan. Conclusions. The morphofunctional rehabilitation of the anterior group of teeth after dental wear, requires a complex examination, with the elaboration and realization of a sequenced treatment plan with multi-aspect curative objectives.
