摘　　要：目的:观察改良型托盘与传统托盘对下颌全口义齿印模的影响,比较义齿修复后的临床效果。方法:对60例无牙颌牙槽嵴条件较差病例进行两种印模方法制取下颌全口义齿印模,义齿戴入后对义齿的固位功能、黏膜情况,舒适性、咀嚼功能、食物嵌塞5项内容进行评价。结果:两组病例在舒适程度、黏膜情况、食物嵌塞、咀嚼功能等方面无显著性差异,P>0.05;但在固位功能方面改良型托盘组明显优于传统托盘组,P<0.05。结论:改良型托盘制取的印模显著提高了下颌全口义齿的吸附力,可以普遍应用于牙槽嵴或黏膜条件差的无牙颌修复患者。Objective： To observe the influence of modified tray and conventional tray on mandible complete denture and the clinical effect after dental restoration. Method： 60 cases that were edentulous in mandible or with inferior alveolar ridge were treated with two methods of mandible complete denture impression. Five items were evaluated after wearing den- ture, retaining function, mucosa, comfort, masticatory function and food impaction, etc. Result： There was no significant dif- ference in the two groups in the aspects of comfort and masticatory function, mucosa and food impaction,with P 〉0.05; while in the aspects of retaining function, the group with modified tray was superior to the group with conventional tray, with P 〈 0.05. Conclusion： Impression with modified tray obviously increased the absorption force of mandible complete denture, and may be applicable generally to the patients with inferior alveolar ridge.
