To assess the bone support of the teeth adjacent to a cleft using cone-beam computed tomography (CBCT).
The CBCT scans of 31 patients with unilateral cleft lip and palate (UCLP) were assessed. The data for teeth neighboring the cleft were compared with those of contralateral noncleft teeth. For each tooth analyzed, the distance between the cementoenamel junction (CEJ) and the bone crest (AC) at the buccal side was measured as was the thickness of the buccal bone level at 0, 1, 2, and 4 mm.
The bone thicknesses of the central teeth at the cleft region at the crest and 2 mm apically were statistically significantly thinner than that of the central incisor at a noncleft region. The CEJ-AC distance for central teeth at the cleft region was higher than that for central teeth in a noncleft region.
Subjects with UCLP showed reduced bone support at teeth neighboring the cleft compared with controls. This may cause some problems during orthodontic treatment.
使用锥形束计算机断层扫描（CBCT）评估唇腭裂旁牙齿的骨支持情况。
对31名单侧唇腭裂（UCLP）患者的CBCT扫描图像进行评估。将腭裂旁牙齿的数据与对侧非腭裂牙齿的数据进行比较。对于每颗分析的牙齿，测量颊侧牙骨质釉质界（CEJ）与牙槽嵴顶（AC）之间的距离，以及在0、1、2和4毫米处颊侧骨水平的厚度。
腭裂区域中切牙牙槽嵴顶及根尖2毫米处的骨厚度在统计学上显著薄于非腭裂区域的中切牙。腭裂区域中切牙的CEJ-AC距离高于非腭裂区域中切牙的CEJ-AC距离。
与对照组相比，UCLP患者腭裂旁牙齿的骨支持减少。这可能在正畸治疗期间引起一些问题。
