Summary
Titanium miniplates are temporary anchorage devices used in orthodontics, offering greater versatility and stability when compared to other alternatives. The variety of available miniplates makes it essential to understand their mechanical properties to determine the best therapeutic option and achieve higher success rates. The aim of this study is to assess the tensile strength, maximum force, and deformation of three commercially available miniplates in Chile, providing theoretical insights for clinical practice to facilitate the professional’s selection of the appropriate device for each case. Three types of miniplates (Bone Plate, Osteomed, and Ancorfix) were undergone tensile testing until fracture to determine and compare tensile strength, maximum force, and deformation. Subsequently, statistical analysis was conducted using ANOVA and post hoc tests with Bonferroni correction. Significant differences were observed in tensile strength, maximum force, and deformation when comparing the miniplates. Osteomed exhibited the lowest values in maximum force and experienced less deformation before rupture, whereas the Bone Plate model demonstrated higher tensile strength, tolerating a higher force before fracture. There is a statistically significant difference in maximum force, tensile strength, and deformation among the three evaluated miniplates; however, all are compatible and safe for their use in orthodontics.
