Análisis comparativo de resinas biocompatibles para guías quirúrgicas 3D.

Abstract

Introduction: The incorporation of digital technologies in dentistry has transformed the planning and execution of implant treatments using digital design tools and 3D printing. In this context, 3D surgical guides bring the planning process to the operating room, facilitating more precise implant placement and helping to reduce deviations in traditional procedures. The accuracy of these structures depends on several factors, such as design, printing parameters, post-processing, and material properties, making the selection of appropriate resins essential in the digital implantology process. Aim: To compare the dimensional stability of the biocompatible resins Arma, Antinsky, Nagy, and Portux. Methodology: A quantitative, experimental, and comparative approach was used; the samples were compared by evaluating dimensional measurements before and after the autoclave sterilization process. The Shapiro-Wilk and Wilcoxon tests were used to compare measurements before and after sterilization, with a significance level of p < 0.05. Results: The Arma resin showed a general trend toward dimensional reduction, while Antinsky exhibited smaller variations between the two conditions. In Nagy and Portux3D, the most significant modifications were concentrated at point I2, with changes of 4.82 mm and 5.17 mm, respectively. The Wilcoxon test showed a significant difference in measurements before and after autoclaving only for the Arma resin (p = 0.031).
