- Development of a three-dimensional analysis to locate dental elementsPublication . Binato, Joanna Almeida; Silva, Susana Paula Fernandes Machado da; Bolognese, Ana MariaIntroduction Accompanying routine of the evolution of the dentition include photographs, radiographs, and lateral cephalogram. These, however, provide only a bidimensional representation of the dental and bone structures and it can lead to loss of data, not considering the differences of width, symmetry and facial form. The three-dimensional technology presents countless advantages, where dental structures can be visualised in real size, through different planes and angulations. Objectives The aim of this study is to present a three-dimensional analysis for locate the dental elements, observing their spatial positions and relation with the basal bone, in a pilot study using the developing upper permanent canine. Materials and Methods The data was collected through computerised tomography of 30 children, on mixed dentition. The software used allowed the creation of an individual and bilateral analysis where the proposed measures were obtained threedimensionally. Results This cephalometric analysis was composed by points, lines and planes for the obtainment of the position of the chosen tooth. This can be done for any dental element, whether it is erupted or not into oral cavity. The landmarks located on the upper permanent canine are common to all teeth. The lines and planes on this analysis were generated by landmarks determined on facial bones completely reproducible on any patient. Conclusions As the tomography came to substitute the conventional radiographs, the appearance of new anatomic landmarks and new 3D analysis is natural, more reliable and inevitable with the aim to substitute the ones that have been used on 2D.
