Computer assessment of correctness of mandiblar bones fracture slit integration based on pantomographic radiograms

The method of objective assessment of the correctness mandible bones fracture slit was proposed in the research. At present, treatment results are evaluated by comparing pantomographic pictures made before and after integration. It is not an objective method; the estimation of the integration correctness coefficient is not possible, either. The use of computer processing enables introducing the relative mandible faction dislocation coefficient. Thanks to this, measurable determination of bone faction reposition correctness on pantomograms made after osteosynthesis is possible.

Biomechanical stability analysis in the plate-niting of the mandibular angle

Acta of Bioengineering and Biomechanics

2000

Vol. 2, nr 2

41-49

The purpose of this study was to compare the biomechanical stability of two types of plating (osteosynthesis) used to fix fractures of the mandibular angle. The fixation systems included: (1) a single six-hole miniplate; (2) two miniplates - six-hole as before and an additional four-hole miniplate. All plates and screws used in this experiment were made of stainlees steel (Champy type). A simple angle fracture was made in the mandible models at a standardized location. The stability of the fixations was measured using the holographic interferometry method. Displacements of mandibular bone fragments were examined.
