[摘要]目的：评估应用生物功能性义齿修复系统（BPS）修复全口牙列缺失的临床效果。方法：选择60例全口牙列缺失患者，分为牙槽嵴正常组和牙槽嵴低平组，每组分别采用BPS系统和传统方法进行全口义齿修复。于义齿完成后3d、1个月以及3个月复诊，检查口内黏膜压痛点，采用吸光度法测试义齿的咀嚼效率，利用调查问卷测试患者的满意度，然后进行比较。结果：在牙槽嵴正常组，两种方法制作的全口义齿在压痛点的检测、义齿咀嚼效率及患者的满意度方面，差别无统计学意义（P>0.05）;在牙槽嵴低平组，与传统方法制作的全口义齿相比较，BPS法制作的全口义齿压痛点少、义齿咀嚼效率及患者的满意度高，差别有统计学意义（P<0.05）。结论：BPS全口义齿在牙槽嵴低平患者的修复治疗中，较传统方法制作的义齿有明显优势。

Abstract： Objective To evaluate the clinical effect of the application of biological functional denture restoration system （BPS） in the restoration of edentulous. Methods  60 patients with edentulous were selected and divided into normal alveolar ridge group and low alveolar ridge group. BPS system and traditional method were used for complete denture restoration in each group. After the denture was completed 3 days， 1 month and 3 months later， the pressure points were checked， the chewing efficiency of the denture was tested by absorbance method and the satisfaction of the patients was tested by questionnaire and then compared. Results In the normal alveolar ridge group， there was no significant difference between the two methods in the detection of pressure points， chewing efficiency of the denture and patient satisfaction （P>0.05）. In the low alveolar ridge level group， compared with the traditional method of complete denture， BPS complete denture has fewer tenderness points， better denture mastication efficiency and patient satisfaction， and the difference is statistically significant （P<0.05）.  Conclusion  BPS complete denture has obvious advantages over conventional denture in the restoration of patients with low alveolar ridge.

我國老龄化趋势已日益显著，牙列缺失患者亦逐步增多。由于牙齿及颌位关系的丧失，且因寿命延长，全口牙列缺失患者更换义齿的机会越来越多。尤其对于那些牙槽骨吸收严重的患者，每次更换义齿的过程中，都有因牙槽嵴的降低以及戴用不合适的旧义齿引发其他口腔病变的可能性。利用传统方法制作的全口义齿，患者戴用后往往出现固位力欠佳、义齿易松动脱落、黏膜易疼痛及咀嚼效率低等情况[1]。因此， 针对牙槽骨吸收严重的患者，如何改善全口义齿修复后的咀嚼效率，提高义齿的固位力与稳定性，是全口义齿修复的重点及难点。生物……
