【摘要】：目的:通过测量成人上颌窦容积、窦嵴距和计算气化系数,探讨上颌窦容积和牙槽骨骨量的关系及磨牙脱落对上颌窦的影响。方法:收集190例(361侧上颌窦)患者的CT影像学资料,121例(242侧)正常者为A组;42例(65侧)例磨牙部分脱落者为B组,其中31侧上颌窦1颗磨牙脱落为B1组,22侧上颌窦2颗磨牙脱落为B2组,12侧上颌窦3颗磨牙脱落(残留1颗)为B3组;27例(54侧)上颌牙全部脱落者为C组。通过测量上颌窦容积、窦嵴距和上颌窦各径线,并计算气化系数,分析上颌窦容积与窦嵴距的关系;对比分析3组上颌窦各径线、气化系数、上颌窦容积及窦嵴距的差异。结果:A组上颌窦容积和窦嵴距呈负相关(r=-0.63,P0.05);A组窦嵴距大于其他2组(P0.05),而B组窦嵴距又大于C组(P0.05);C组上颌窦前后径及左右径分别大于A、B组(P0.05);C组气化系数小于A、B组(P0.05)。结论:上颌窦容积和牙槽骨骨量呈负相关,上颌牙全部脱落促进上颌窦变形,上颌窦容积有减小趋势。
[Abstract]:Objective: to investigate the relationship between maxillary sinus volume and alveolar bone mass and the effect of molar loss on maxillary sinus by measuring the volume of maxillary sinus, crest distance of sinus and calculation of gasification coefficient.Methods: the CT imaging data of 190 patients with maxillary sinus (n = 190, n = 121, n = 121, n = 242) were: group A (n = 42, n = 65) and group B, with partial molar loss (n = 65).One molar of 31 sides of maxillary sinus was lost in group B1, 22 sides of maxillary sinus, 2 molars in group B2, 12 sides of maxillary sinus in group B2, 3 molars in group B 3 (residual 1), 27 cases in group B 3 and 54 sides in group B 3, all maxillary teeth were lost in group C.Conclusion: there is a negative correlation between maxillary sinus volume and alveolar bone mass. All maxillary teeth fall off to promote maxillary sinus deformation and maxillary sinus volume decreases.
