CLINICAL AND SPECIFIC CHANGES OF DENTAL ARCHES AND OCCLUSAL RELATIONS AFTER FIRST PERMANENT MOLAR LOSS, IN TEENAGERS AND YOUNG ADULTS

Abstract

Interrupted continuity of the dental arches by the first permanent molars loss in adolescents and young people is followed, more frequently and more rapidly than in adults, by morphological changes due to migration of teeth in the sagittal, transversal and vertical plans. These changes of position are likely to trigger an occlusal dysfunction, with a number of negative consequences for the entire dental/maxillary system. The aim of this study was to determine and reveal the changes of dental arches and occlusal relations after first permanent molar loss, in a population (224) of teenagers and young adults, with ages between 12 and 22 years old. The complete dental examination was conducted by two examiners, and data were recorded for each study participant, in terms of horizontal and vertical migrations. The most frequently changes of dimensions in dental arches were observed after the loss of first permanent mandibular molars, with uneven occlusal plane, asymmetry of sagittal and transverse curves and the appearance of premature contacts with a pathogenic action more pronounced in young adults
