Clinical study on artificial tooth selections for complete denture in edentulons jaws patients

目的比较不同人工牙用于全口义齿修复的无牙颌患者的临床效果。方法行全口义齿修复的无牙颌患者76例，根据患者患病情况以及人工牙选择的不同将患者分为三组，比较治疗3个月后患者对全口义齿修复的满意度。结果Ⅰ、Ⅱ类患者选择两种不同的人工牙进行全义齿修复后，患者外观、语音、咀嚼、固位以及舒适性等差异均无统计学意义（均P〉0．05）；Ⅲ类患者选择两种不同的人工牙进行全义齿修复后，选择长正中合成树脂牙患者在语音、咀嚼以及固位方面的满意度高于选择解剖牙合型树脂牙，差异均有统计学意义（t=2．014，2．217，2．314，均P〈0．05）；而在外观以及舒适性方面差异均无统计学意义（均P〉0．05）。结论对无牙颌患者进行全口义齿修复时，需要对患者进行全面考虑，选择恰当的人工牙。

Results The artificial teeth of full denture patients, speech,mastication,appearance,retention and comfort and so on for Class I and Class II patients had no significant difference （ all P 〉 0.05）. The artificial teeth of full denture, selection of long median synthesis resin dental patients in speech, mastication and retention of satisfaction than selected anatomic occlusal resin teeth in Class III for a choice of two different had significant differences （ t = 2. 014,2. 217,2. 314, all P 〈 0.05 ）, but the appearance and comfort had no significant differences （t = 1. 023,0.957, all P 〉 0.05 ）.
