Maxil006Cary Anterior Alveolar Arch (AA) Shape Analysis: A Cone Beam Computed Tomography Study

Abstract

The aim of this study is classified the shapes of the alveolar arches in the anterior aesthetic region using cone beam computed tomography images. Methods:The sample consisted of 40 young adults, the age of the subjects ranged between 23 and 33 years, with a mean of 25.90 years. All subjects performed cone-beam computed tomography (CBCT), evaluating the axial view. Statistical software (SPSS version 20.0; IBM Corp., Arm NY, USA) was used to analyze the data for inter-examiner calibration, an intraclass correlation coefficient test was performed with a confidence level of 95%. Results: The predominant form of the AA arch is the short medium with a percentage of 60% equivalent to 24 subjects in the sample, and with the lowest percentage the form of the AA arch is long narrow arch with a 7 .5% equivalent to 3 of the 40 total subjects of the sample. Conclusion: The shape of the anterior alveolar arch, using the formula of the fourth-degree polynomial that has been shown to be the most suitable to represent a smooth and natural curve of the arch, can be classified into long narrow, short medium, long medium and long wide arches. Further studies on this are recommended
