Background: This study evaluates the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) on the quality and quantity of regenerated bone when injected into distracted alveolar bone.
Methods: Sixteen adult beagle dogs were assigned to either the control or rhBMP-2 group. After distraction was completed, an rhBMP-2 dose of 330 μg in 0.
Objective: Premaxillary distraction osteogenesis was introduced using intraoral devices to correct maxillary hypoplasia and lengthen the alveolar bone horizontally in a patient with unilateral cleft lip and palate.
Methods: For premaxillary distraction osteogenesis, Le Fort I osteotomy was performed. Vertical osteotomy lines were located distally of the upper right canine and left first premolar to separate the anterior segment of the maxilla.
