Distracción alveolar. Caso clínico

Abstract

Distraction osteogenesis can obtein the biological formation of new bone tissue between two fragments of mature bone that being slowly and progressively separated by mechanical means. Codivilla originally proposed distraction osteogenesis in 1905, although he had little clinical success with the technique. Illizarov began to lengthen long bones in the 1940's and established basic biological principies of the distraction process, known as the Illizarov principies. Gradual traction creates a stress that stimulates regeneration in live tissues. The volume and shape of the new bone depend on interactions between mechanical forces and blood supply. We present a case of a 26 years old woman who had complex mandible fracture and lost the teeth and the adjacent alveolar bone from her anterior mandible in a traffic crash. The osteosynthesis was done with titanium plates and screws and after surgery alveolar distracction osteogenesis was applied. The objective of this paper is to report a case of alveolar distraction and make a review of the literature.
