Abstract
Biological tissue healing has been developed in many research protocols, once the use of biomaterials and technologic devices during postoperative period may enhance functional and aesthetic rehabilitation. The objective of this paper was to map the magnetic field in a prototype developed for bone healing stimulation in animal models. The prototype was developed with two parallel magnets positioned in attraction to each other. The magnets were fixed and allowed to move in all directions through 3 screws. The animal model chosen was Wistar rat and the fracture model was an incomplete femur osteotomy gap. The animals were divided in 4 groups of magnetic stimulation. The experimental times were 7, 14, 21 and 28 postoperative days. The field’s intensity perpendicular to the osteotomy gap was ranged from -101 to -216 mT in the center of the magnetic prototype. During the postoperative stimulation, the osteotomy gap was positioned perpendicular to the center of the field. The project was submitted to the Ethical Research Committee of Positivo University and was approved under the protocol 006/2009. To the result analysis, it was measured the field intensity with a gaussimeter in 60 positions. The data were showed in graphics. Further histological and mechanical analysis will be performed on the bone specimens. As unpublished results it is expected to be possible to develop an experimental protocol to be used in future animal researches and bone fracture’s models.
