Por qué importa

Estudio de elementos finitos publicado en AJO-DO que valida biomecánicamente un nuevo diseño de miniplaca para anclaje en el sector anterior maxilar: al aplicar varios vectores de fuerza en dos puntos a la vez, la deformación y las tensiones sobre hueso y tornillos son iguales o menores que con un punto único. Es la base de ingeniería que respalda las mecánicas de intrusión en masa que Ertty Silva utiliza en clínica.

Abstract original

Introduction: Multiple force vector applications may be indicated when an arch segment or en masse intrusion is needed. This finite element method study aimed to evaluate the total deformation and the stress yielded in the bone and the miniplate when forces with different directions and magnitudes were applied. Methods: A 3-dimensional finite element model was constructed by reproducing the characteristics of a physical prototyped skull model. Seven situations were investigated, which diverged in the point of force application, the direction and the number of force vectors, and the force magnitudes. Results: When the force was applied at 1 point, most deformation and stress appeared in the trans-mucosal arm below the step bend and at the force application point. Similar or better performances could be observed when the forces were simultaneously applied at the 2 points. Conclusions: The newly designed miniplate showed similar or improved performances when multiple vectors were applied at the 2 points simultaneously compared with the force applied at 1 point.
