Comparación del ángulo de convergencia en dientes preparados para coronas según la clínica cursada por estudiantes de odontología de la Universidad Peruana de Ciencias Aplicadas (UPC)

Abstract

The aim of this study was to compare the convergence angle in teeth prepared for crowns for students of School of Dentistry Peruvian University of Applied Sciences (UPC). 76 students in 7th to 10th cycle prepared 152 dental pieces between incisors and premolars, to receive a ceramic metal crown. The images of the vestibulolingual (VL) and mesiodistal (MD) faces of the prepared teeth were measured and the AC of said faces was measured with the aid of AutoCAD software (Autodesk). A significant difference (p = 0.003) was found in part 21 on the VL face, due to the position of the piece in the oral cavity, indirect vision and operator ability. The highest average AC in piece 21 was in the face VL and MD with 25.27 º + 8.47 and 15.81 º + 4.23 respectively. On the other hand, for piece 24 in the VL and MD was 14.83 º and 17.45 º respectively. There was no great difference between the AC of the other carved pieces.
