The treatment of edentulism with traditional complete dentures can often induce impaired masticatory function due to limited retention and stability, especially in the lower jaw. Mandibular interforaminal implants have been widely used to stabilize the dentures, consequently improving masticatory performance in edentulous individuals. The aim of the present study was to document the influence of this improved masticatory function on patient satisfaction and quality of life of patients wearing mandibular implant-supported overdentures. Sixty-two patients treated with various types of implant-supported mandibular overdentures between 2004 and 2007 were included in this retrospective study. Maximum bite force (MBF) was measured bilaterally using a device with 2 strain gauges connected to a strain gauge measurement system. All the included patients were asked to fill out visual analog scale (VAS) forms based on general and chewing satisfaction and OHIP-14 forms. Results were analyzed by the Spearman rho test. No statistically significant correlation was found between MBF values and VAS general or VAS chewing satisfaction or Oral Health Impact Profile scores (P > .05). The results indicate that MBF is not associated with the satisfaction or quality of life of implant-supported mandibular overdenture wearers.
使用传统全口义齿治疗无牙颌常常会因固位和稳定性有限而导致咀嚼功能受损，尤其是在下颌。下颌孔间种植体已被广泛用于稳定义齿，从而改善无牙患者的咀嚼性能。本研究的目的是记录这种改善的咀嚼功能对佩戴下颌种植支持覆盖义齿患者的满意度和生活质量的影响。这项回顾性研究纳入了2004年至2007年间接受各种类型种植支持下颌覆盖义齿治疗的62例患者。使用连接到应变片测量系统的带有2个应变片的装置双侧测量最大咬合力（MBF）。所有纳入的患者都被要求根据总体和咀嚼满意度填写视觉模拟量表（VAS）表格以及OHIP - 14表格。结果通过Spearman秩相关检验进行分析。在MBF值与VAS总体或VAS咀嚼满意度或口腔健康影响概况评分之间未发现统计学上的显著相关性（P > 0.05）。结果表明，MBF与种植支持下颌覆盖义齿佩戴者的满意度或生活质量无关。
