A correlation between the maxillary transversal growth and the width of the upper central incisor
Journal Title: Medicine in Evolution - Year 2017, Vol 0, Issue 3
Abstract
Objectives: Dentoalveolar discrepancies are more common nowadays, due to a general trend of the viscerocranium to decrease its size. In this context, early orthodontic treatment - after an early and correct diagnosis - can prevent the orthodontic problems from becoming permanent. Therefore, the dentist needs simple and efficient methods of detection and interception of dentoalveolar discrepancies, which can be applied easily on as many patients as possible. On this matter, starting from Bolton’s analysis and the Cephalometric landmarks, the objective of this study is to determine the correlation between the permanent upper central incisor’s width, first permanent tooth erupting on the maxillary arch in the frontal area (making it easily accesible in practice), and the development of the maxilla, respectively. Materials and methods: We used 300 study models of adult patients. On these, the width of the maxillary central incisors (M-D) measured incisally and the cross dimension of the maxillary arch, between the craniometric Ectomolare-Ectomolare points, were measured with a digital caliper. Subsequently, the correlation between the mesio-distal width of the central incisor and the transversal development of the upper jaw was examined. Results: After analysis, it was found that there is a correlation between the mesio-distal width of the central incisor and the development of the upper jaw, and a growth index was established. Discussion: This study wants to help the practitioners to easily identify the maxillary growth disturbances, by determining the upper jaw’s future approximate dimensions from an early stage, using only the upper central incisor’s width. Also, knowing the correlation between the two, the practitioner can easily recreate the correct dimension and shape of the frontal teeth, when dealing with edentulous patients. Conclusions: The growth index can provide valuable data in intercepting the dentoalveolar discrepancies and other orthodontic problems, being a fast, easily available and noninvasive method of diagnosis. For the eldery, edentulous patients, it can give the dentist a guide for the aesthetic outcome of the future prosthetic restoration.
