Avaliação do espaço interdentário de dentes superiores posteriores em tomografia computadorizada de feixe cônico para planejamento de microimplantes

Abstract

Introduction: The knowledge of interdental distance is crucial in microimplant planning. Objectives: Evaluation of the interdental space of posterior superior teeth in cone beam computed tomography for microimplant planning. Materials and method: The interdental distance of the posterior maxillary teeth was analyzed by Cone Beam Computed Tomography in 60 maxilla exams. CS 3D Imaging 3.2.9 software was used to measure the distance between the teeth. Three interradicular measurements were made of the maxillary posterior teeth at the apical, middle and cemento-enamel junction (CEJ), taking 3 measurements (vestibular, middle and palatine) in each segment of the root, totaling 9 distances Interdental. Data were submitted to ANOVA and Tukey statistical analysis (p <0.05). Results: The highest mean of the interdental distance was observed between the second premolar and the first molar more apically and by the palatine (left side 5,375 mm ± 2,044 and right 6,359 mm ± 3,398). These distances differ statistically significantly from the distances between the first and second molars, and second and third molars, but did not differ statistically from the distance between the first and second premolars. Conclusions: The interdental distances more apically between the second premolar and the first molar, determine the best sites for placement of microimplants.
