One hundred and fifty 55-year-old edentulous subjects (104 women and 46 men) were interviewed. Materials, conditions, functional stabilities, and occlusions of complete dentures, and resorption of alveolar crests were recorded and assessed. The dentures were in good condition in 52% of subjects. Occlusion was correct in 45% of cases. Every fifth mandibular denture exhibited good functional stability. The mean age of dentures in good condition and functionally stable was statistically significantly lower than the mean age of dentures poor in these respects. Severe alveolar resorption contributed to poor functional stability of dentures (P = 0.0068 (maxilla), P = 0.0023 (mandible)) and to incorrect occlusion (P = 0.0177). Good agreement was noted between objective and subjective opinions of denture function (P = 0.01 (maxillary denture), P = 0.01 (mandibular denture)). Although oral rehabilitation with endosseous implants is common and, objectively, needs for such treatment existed, only 22 subjects (15%) who had recently had their dentures renewed and were experiencing problems with functional stability were interested in implant-retained overdentures.
对150名55岁的无牙颌受试者（104名女性和46名男性）进行了访谈。记录并评估了全口义齿的材料、状况、功能稳定性、咬合情况以及牙槽嵴的吸收情况。52%的受试者义齿状况良好。45%的病例咬合正确。每五副下颌义齿中有一副表现出良好的功能稳定性。状况良好且功能稳定的义齿的平均使用年限在统计学上显著低于在这些方面较差的义齿的平均使用年限。严重的牙槽骨吸收导致义齿功能稳定性差（上颌：P = 0.0068，下颌：P = 0.0023）以及咬合不正确（P = 0.0177）。义齿功能的客观和主观评价之间存在良好的一致性（上颌义齿：P = 0.01，下颌义齿：P = 0.01）。尽管骨内种植体的口腔修复很常见，而且客观上存在这种治疗需求，但在最近更换了义齿且功能稳定性出现问题的受试者中，只有22名（15%）对种植体固位覆盖义齿感兴趣。
