Motives have to be evaluated, and certain cases have to be excluded such as those with morbid obesity, or those with severe associated pathologies, while low CPAP tolerance cases or those with a severe maxillofacial deformity that would clearly benefit from treatment entailing corrective surgery should be included.
However, the available information on this subject is still scarce. Mandibular alveolar ridge augmentation in the dog using distraction osteogenesis. In maxillary bones, the ossification is largely intramembranous, although foci of endochondral ossification have been reported by some authors. Management of severe mandibular retrognathia in the adult patient using distraction osteogenesis.
Other authors had followed this idea, but it was only in the decade of the 50’s that Ilizarov a, b promoted the extend bone by distraction osteogenesis having consistent and previsible results. This segmentary osteotomy was performed adjacent to the teeth that limited the bone defect, respecting the inferior alveolar duct pathway in the mandible.

Otolaryngol Head Neck Surg ; DO have been used successfully in distraccoon surgeries of increase bone rim with diverse purposes.

Latency phase is the period between performance of osteotomy and start of the traction, during which soft callus is formed. Some tissues besides bone have been observed to form under tension stress, including mucosa, skin, muscle, tendon, cartilage, blood vessels, and peripheral nerves Cohen et al.
The use indications have grown for the most diverse types of bones deformities.

In clinical alveolar distraction studies, some authors attempted to approach this frequency by applying more than 1 distraction procedure per day, distributing the daily amount of distraction between 2 sessions of 0.
