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.
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.
Dental volume tomography could correctly schedule the scope of surgical intervention and localize a graft after surgery.
研究牙科容积断层扫描在检查先天性牙槽突和硬腭裂患者中的能力。对象与方法。对35例先天性牙槽突和硬腭裂患者使用牙科容积断层扫描仪I-CAT锥形X射线束扫描仪进行检查。
在规划牙槽突和硬腭缺损水平的骨重建手术时，牙科容积断层扫描能够确定骨缺损的范围、大小、口鼻瘘的存在、双侧腭裂中上颌间骨的位置、用于自体移植的下巴区域骨组织的状态（大小、密度特征）以及颌面畸形的程度。牙科容积断层扫描可以在术后早期以及术后1、3和6个月确定牙槽突修复的正确性、再生骨的范围、骨再生的程度、固定元件的位置以及供区床的状态。
牙科容积断层扫描可以正确安排手术干预的范围并在术后定位移植骨。
