Análisis comparativo de la eficiencia en el uso de fresas cilíndrica vs troncocónica en el tallado de muñones por estudiantes de la UCSG, B2024.

Abstract

Introduction: In restorative dentistry, the preparation of dental abutments is a fundamental procedure that requires precision and efficiency. Cylindrical and tapered burs are widely used for this purpose, each with specific characteristics that may influence clinical outcomes. Understanding their performance differences is crucial for optimizing tooth preparation, reducing clinical working time, and ensuring satisfactory results for both the practitioner and the patient. Objective: To analyze the efficiency of cylindrical versus tapered burs in abutment preparation by UCSG students, B2024. Materials and Methods: The study included 20 seventh-cycle students with preclinical experience in tooth preparation and the use of medium-grit, round-ended cylindrical and tapered diamond burs. Each student prepared two teeth from the same patient, recording the preparation time, the number and type of corrections made by the instructor, and their perception of each bur. Results: no significant differences were found between cylindrical and conical burs in any of the variables studied. The cylindrical bur showed a more favorable perception of comfort among students. Additionally, carving time was shorter and more consistent compared to the conical bur. Conclusions: The results highlight the cylindrical cutter as a more consistent and favorable tool in terms of comfort and working times.
