摘要: 目的:应用锥形束CT(CBCT)分析上颌窦外侧骨壁的厚度,为口腔种植上颌窦底外提升术的手术指导和风险评估提供参考。方法:选取412例研究对象的上颌窦CBCT影像资料,结合种植专用Simplant软件,进行三维重建,选取测量截面,测量上颌窦外侧骨壁的厚度。采用SPSS17.0软件包对数据进行统计学分析。结果:412例(824侧)研究对象中,上颌窦外侧骨壁的平均厚度在上颌第二前磨牙(P2)、上颌第一磨牙(M1)和上颌第二磨牙(M2)区分别为(2.23±1.07) mm、(2.19±1.45) mm和(1.41±0.81) mm;左右侧上颌窦外侧骨壁厚度在 P2区具有显著差异(P<0.01);男女间上颌窦外侧骨壁厚度在P2和 M2具有显著差异(P<0.05),男性较女性稍厚;不同年龄组中M1和 M2区的上颌窦外侧骨壁厚度有显著差异(P<0.05);牙缺失对于上颌窦外侧骨壁厚度的变化无显著影响。结论:锥形束CT可精确测量上颌窦外侧骨壁的厚度变化,不同牙位对应的上颌窦外侧骨壁厚度不同,上颌前磨牙区高于上颌磨牙区,最薄处位于M2区。不同年龄、性别之间和左右侧有一定差异。

Abstract: PURPOSE: To evaluate maxillary sinus lateral wall thickness by use of cone-beam computed tomography (CBCT), in order to provide anatomical basis for preoperative risk assessment and operation guidance of maxillary sinus lifting. METHODS: Using SimPlant software, the 3D images were reconstructed with CBCT images from 412 subjects and the thickness of maxillary sinus lateral wall were evaluated at measurement plane. The data was analyzed with SPSS17.0 software package. RESULTS: Among 412 subjects (824 sides), the mean thickness of maxillary sinus lateral wall at the second premolar (P2), the first molar (M1) and the second molar (M2) was 2.23±1.07 mm, 2.19±1.45 mm and 1.41±0.81 mm, respectively. The thickness of maxillary sinus lateral wall on the left side were significantly different from that on the right side at P2 (P<0.01). Significant gender differences on the thickness of maxillary sinus lateral wall were demonstrated at P2 and M2 (P<0.05), and the thickness in men were thicker than that in women. The thickness of maxillary sinus lateral wall at M1 and M2 were significantly different among different age groups (P<0.05). There was no significant difference on the lateral wall thickness with respect to presence or absence of tooth. CONCLUSIONS: CBCT can accurately measure the thickness of maxillary sinus lateral wall. The mean thickness of lateral wall changes at different reference points. The value at premolar region is greater than that at molar region, and the maxillary sinus lateral wall is the thinnest at M2. There are significant differences in the mean thickness of the lateral wall with respect to age, gender, and side of maxillay sinus.
