[Capacities of dental volume tomography of congenital clefts of the alveolar process and hard palatea].

OBJECTIVE

to study the capacities of dental volume tomography in the examination of patients with congenital clefts of the alveolar process and hard palate. Subjects and methods. Thirty-five patients with congenital clefts of the alveolar process and hard palate were examined on a dental volume tomograph, an I-CAT cone X-ray beam scanner.

RESULTS

On planning osteoreconstructive operations at the level of alveolar process and hard palate defects, dental volume tomography allowed the determination of the extent of a bone defect, sizes, the presence of oronasal fistulas, the position of the intermaxilla in bilateral clefts, the state of bone tissue (sizes, density characteristics) in the chin region for an autograft, and the degree of maxillofacial deformity. Dental volume tomography could determine the correctness of alveolar process restoration, the extent of the regenerated bone, the degree of osteoregeneration, the position of fixing elements, and the state of the donor bed in the early postoperative period and at 1, 3, and 6 months.

CONCLUSION

Dental volume tomography could correctly schedule the scope of surgical intervention and localize a graft after surgery.
