[Tooth vitality after interalvolar and perialveolar osteotomies in the maxilla]

Follow-up examinations in 39 patients with osteotomies in the maxillary alveolar ridge for correcting jaw deformities showed that the risk of devitalization of teeth in the mobilized fragments and in the firm residual parts of the jaw is small. In interalveolar osteotomies this risk is slightly greater than in transalveolar osteotomies, because of the restricted space.
