摘　　要：目的:比较息止颌位法及发音法确定的无牙颌垂直距离与拔牙前记录的差异。方法:选择6例患者,先记录口内余留天然牙维持的正常垂直距离,在因治疗需要拔除余留牙后,由5位医师应用息止颌位法,5位医师应用发音法重新确定其垂直距离,将结果与拔牙前记录的正常垂直距离进行比较。结果:息止颌位法确定的垂直距离明显高于拔牙前记录,发音法确定的垂直距离更接近拔牙前记录。结论:与息止颌位法相比,发音法是一种受主观因素影响更小的,更可靠的垂直距离确定方法。Objective：To determine the vertical dimension using intercoolusal distance and closest speaking space,then compare them with pre-extraction record.Methods：Six patients,who finally became to an edentulous were taken occlusal records before extraction,and then determined the vertical dimension using interocclusal distance by 5 experienced doctors and using closest speaking space by 5experienced doctors.Results：The vertical dimension determined by interocclusal distance was much higher than pre-extraction record,but the vertical dimension determined by closest speaking space was much closer to pre-extraction record.Conclusion：Comparing with interocclusal distance method,closest speaking space is a more reliable method which is less affected by subjectivity.
