| Popis: | Purpose The aim of the present study was to evaluate the performances of 5 different plating techniques for fixation of favorable mandibular angle fractures using the 3-dimensional finite element analysis (FEA) method. Materials and Methods Five different miniplate placement configurations were considered for the fixation of favorable mandibular angle fractures. The following models were created: a double parallel miniplate (M1) placed at the halfway point of the mandibular angle height; a one-third superior-positioned miniplate (M2); a single miniplate (M3) placed at the halfway point of the mandibular angle height (one-half middle-positioned); a one-third inferior-positioned miniplate (M4); and an X-shape miniplate (M5). Results The M1 and M4 miniplates showed the lowest mechanical stress compared with the other configurations, whereas the M3 and M5 miniplates showed the highest stress levels. Conclusion For favorable mandibular angle fractures, the authors suggest the M1 miniplate or, if used alone, the M4 miniplate is adequate for rigid fixation. |
