目的：通过研究正常牙合关系丧失患者进行咬合重建修复前后脑血流速的变化，从而证明恢复牙合关系的重要性，为脑血管疾病的防治工作提供新的理论依据和参考。方法选择30名同意配合实验者，应用经颅多普勒超声诊断仪，测定恢复咬合功能1个月的时间段前后患者脑血流速的变化，记录数据并进行统计学处理。结果显示咬合重建修复功能前后大脑中动脉血流的峰流速经统计学分析有显著性差异(P<0.01)，恢复咬合功能前后有统计学意义。结论牙齿缺失与恢复可提高大脑中动脉的血流速度及血管供血量，提示对缺血性脑血管疾病的发生有一定影响，应近一步深入研究。

Objective To study the changes of cerebral blood flow velocity which before and after occlusal rehabilita-tion on patients lost normal occlusal relationship, to show the importance of occlusal recovery and to provide the new theoretical basis and reference for the prevention and treatment of cerebrovascular disease. Methods Selected 30 pa-tients who had agree to cooperate, then by using the transcranial doppler ultrasound diagnostic instrument, measured the changes of patients'cerebral blood flow velocity which before and after 1 month time since the function of occlusion had been restored, recorded the data and made the statistical processing. Results The subjects before and after the restoration of end of systolic peak velocity, diastolic peak velocity and average peak expiratory flow rate had signifi-cantly differences(P<0.05). Conclusion The loss and recovery of teeth can improve the blood flow velocity of middle cerebral artery and the vascular blood flow, which hints certain influence to the occurance of schemic cerebrovascular disease, and that need further in-depth study.
