目的探讨吞咽法所获得的全口义齿水平颌位关系的临床效果。方法选择2008年5月至2009年9月在承德市口腔医院进行全口义齿修复的无牙颌患者80例,随机分为2组,每组40例。分别用吞咽法和卷舌法确定水平颌位关系,并完成全口义齿的制作。观察两组全口义齿在口内的咬合关系与模型的一致性。结果用吞咽法所确定水平颌位关系的全口义齿在口内的咬合关系与模型一致性Ⅰ、Ⅱ、Ⅲ类者分别为39、1、0例,而对照组分别为29、7、4例,两组比较差异具有统计学意义(χ2=7.382,P=0.023)。结论利用吞咽法所获得的全口义齿水平颌位关系准确性较高,可以做为确定全口义齿水平颌位关系的有效方法。
Objective To investigate the clinical effect of mandibular denture horizontal jaw position obtained by swallowing. Methods Eighty edentulous patients with complete denture repaired in Chengde Stomatological Hospital from May 2008 to September 2009 were randomly divided into two groups (40 in each group). Determine the relationship between horizontal jaw position by swallowing method and rolling tongue method, respectively, and complete the production of complete denture. Observe the occlusion relationship between two sets of complete dentures in the mouth and model consistency. Results The occlusal relationship between the maxillary dentures and the model in the maxillofacial level was determined by the swallowing method. The I, II, and III groups were 39, 1, and 0 cases respectively, while the control group were 29, 7, and 4 cases , The difference between the two groups was statistically significant (χ2 = 7.382, P = 0.023). Conclusion The accuracy of the horizontal maxillary position of the complete denture obtained by the swallowing method is high, which can be used as an effective method to determine the level of the maxillary position of the complete denture.
