Model simulated surgery using the Alveolar Distraction Device. Combined deficiencies in bone and soft tissue. Compromised wound healing environment. Secondary indications . Limitations Must have a minimum quantity of bone transport and anchorage segment must have adequate strength to withstand forces of mobilization and transport.
Expansion occurs only in the direction of transport.
The distraction process may not produce the anatomical objective in a single step. Maxillofacial skeletal deformities are most often complex and three dimensional in nature. Alveolar deformities are not an exception. It is rare that the distraction process alone would result in an alveolar ridge of ideal shape and size. Usually additional osteoplasty is indicated.
