The paper presents experimental and numerical analyses of two cases of mandibular corpus fractures cured by means of miniplate implantation. In the laboratory tests, strain gauges and electronic speckle pattern interferometry methods were used, while in the numerical simulations finite element analyses were applied. The aim of such a combined approach was to verify a correctness of the numerical model applied with regard to the assumptions and simplifications which had been done when creating FEM for human mandible: healthy, broken and stabilized with miniplate implants.
The authors report on the application of the NiTi and TiNiCo shape memory clamps for the connection of bone fracture in 81 patients suffering from mandible fractures. They have also made an attempt of work out a new, so far not used, method of gradual bone lengthening which uses NiTi superelastic distraction devices. So far to operations have been performed on two pigs where the U-shaped NiTi superelastic distraction devices where used and placed immediately on the bone above the periosteum. Too few attempts are not enough to allow for an objective evaluation of the proposed method of bone lengthening.
