【摘要】：目的:应用锥形束CT(CBCT)测量成年人与青少年的颧牙槽嵴区域的骨宽度、皮质骨厚度及窦底高度,并评价2组的差异,为临床中颧牙槽嵴区微种植体的植入提供参考。方法:选取成年人个别正常鉭志愿者和安氏Ⅰ类青少年患者各30例,获取其口腔颌面部CBCT扫描影像。测量颧牙槽嵴区域的骨宽度、皮质骨厚度及上颌窦底高度,并对测量数据进行统计学分析。结果:两实验组颧牙槽嵴区域均为第二前磨牙和第一磨牙之间的骨宽度最大,且每层的5个测量值均表现为随测量点向颅方移动骨宽度值逐渐减小。两实验组各层颧牙槽嵴区骨宽度与窦底高度成正相关关系。结论:成年人组各位置骨宽度平均值及皮质骨厚度平均值均较青少年组相应位置大。颧牙槽嵴区骨宽度随窦底高度增大而增大。2组样本上颌窦个体差异均非常大,植入微种植体前需拍摄CBCT以确定是否满足植入条件。
[Abstract]:Objective: to measure the width of bone, the thickness of cortical bone and the height of sinus floor in the zygomatical-alveolar ridge region of adults and adolescents by CT-CBCT, and to evaluate the difference between the two groups. Methods: 30 cases of adult normal tantalum volunteers and 30 cases of Adolescent type I patients were selected, which provided reference for clinical application of microimplants in zygomatical-alveolar ridge region. CBCT images of the oral and maxillofacial region were obtained. The bone width, cortical bone thickness and the height of the maxillary sinus floor of the zygomatical-alveolar ridge region were measured. Results: the width of bone between the second premolar and the first molar was the largest in the two experimental groups. The bone width of the zygomatical-alveolar ridge in each layer of the two experimental groups was positively correlated with the height of the sinus bottom. Conclusion: the bone width of each position in the adult group is positively correlated with the height of the bottom of the sinus. The mean value and average cortical bone thickness were larger than those in the adolescent group. The width of the zygomatic alveolar ridge increased with the increase of the height of the bottom of the sinus.2 the individual differences of maxillary sinus in group 2 were very great. CBCT should be photographed before microimplants are implanted to determine whether the implantation conditions are satisfied.
