摘　　要：本文对２０例行即刻全口义齿修复的患者，采用ＳＧＧ下颌运动轨迹描记仪来描记其修复３个月时以及再次全口义齿修复３个月时的下颌切点边缘运动轨迹，并进行测量分析。结果表明：即刻全口义齿修复３个月时，患者下颌切点边缘运动范围明显小于其再次全口义齿修复３个月时的运动范围，前者仅为后者的５９．００％～６９．９５％（Ｐ＜０．０１）。可见戴用即刻全口义齿的患者其下颌切点边缘运动范围受到限制，所以即刻全口义齿只能作为一种过渡性、治疗性的义齿，患者戴用３个月后必须再次全口义齿修复。The mandibular incisor point border movement orbits of 20 patients wearing immediate complete dentures for 3 months and the same patients wearing the second complete dentures for 3 months were raced by SGG then measured and analysed. The results showed that the ranges of mandibular incisor point border movement of patients wearing immediate complete dentures for 3onths were significantly narrower than those of the same patients wearing the second complete dentures for 3 months (P<0.01). The ratio of the former to the latterwas only 59. 00% 69. 96%. It could be concluded that the ranges of mandibular incisor point border movement of immediate complete denture wearers were limited.Thus the immediate complete dentures were transitional dentures and only used for treating purpose. The patients must have another pair of complete dentures after 3months interim.
