| 目的 比较生物功能性修复系统（Bio-functionnal Prothetic System，BPS）和传统方法对下颌低平牙槽嵴修复效果的影响。方法 选择10例口颌系统基本正常，下颌牙槽嵴重度吸收的无牙颌患者，分别采用BPS和传统方法进行全口义齿修复，随机选择戴用顺序，在修复后1、3、6个月后分别对义齿的固位力、咀嚼效能进行测定，并在戴用义齿1个月时进行满意度问卷调查。结果 在修复后1、3、6个月，BPS全口义齿的下颌义齿固位力高于传统全口义齿，差异具有统计学意义（P<0.05）；2种全口义齿吸光度值作比较，在各个检测时期，BPS组吸光度值保持稳定，均高于传统全口义齿（P<0.05），传统全口义齿在3个月和6个月后吸光度值有所回升，与第1个月相比具有统计学意义，但仍低于同时期的BPS组（P<0.05）；问卷调查显示，BPS组的主观满意度明显高于传统组；6个月后，10位患者均表示BPS全口义齿更舒适，不容易脱落。结论 采用BPS完成的义齿修复应用于下颌低平牙槽嵴的无牙颌患者时，能取得更好的修复效果。 |

| Objective The aim of this study was to compare the effects of Bio-functional Prothetic system (BPS) and traditional methods on the restoration of mandibular low-level alveolar ridge. Methods Ten edentulous patients with normal oral and maxillofacial system and severe absorption of alveolar ridge were selected. BPS and traditional methods were used for complete denture restoration. Random selection of wearing order, Retention and masticatory efficiency of dentures were measured 1, 3 and 6 months after restoration. Satisfaction questionnaires were conducted at 1 month after wearing dentures. Results At 1, 3 and 6 months after restoration, the retention of BPS complete denture was higher than that of traditional complete denture (P<0.05).The absorbance values of two kinds of complete dentures were compared. The absorbance values of BPS group remained stable in each testing period, which was higher than that of traditional complete dentures (P<0.05). The absorbance of the traditional complete denture increased after 3 months and 6 months, which was statistically significant compared with the first month, but still lower than the BPS complete denture detection value in the same period, and had statistical significance (P<0.05). Questionnaire survey showed that the subjective satisfaction of BPS group was significantly higher than that of the traditional group. Six months later, all 10 patients chose BPS complete denture as the future normal denture. All 10 patients indicated that BPS complete denture was more comfortable and not easy to fall off. Conclusion BPS can make full use of patients'oral physiological conditions to complete denture restoration, and can achieve better restoration effect in edentulous jaw patients with lower alveolar ridge. |
