全口义齿的稳定性是修复成功的关键因素,稳定性指义齿对水平向力和转动力的抵抗性能,能防止义齿基托左右或前后撬动,使病人自我感觉舒适。随着老龄化社会发展,老年人尤其是高龄老人牙列缺失状况普遍和复杂程度大幅提高。我们对59例牙槽嵴中、重度萎缩的高龄老人进行全口义齿修复,对义齿的稳定性作一探讨。 The stability of the complete denture is the key factor to the success of the repair. The stability refers to the resistance of the teeth to the horizontal force and the rotation force, which can prevent the denture base from leveraging to the left and right or front and back so that the patient feels self-comfortable. With the development of an aging society, the prevalence and complexity of dentition deficits among the elderly, especially the elderly, have been greatly increased. In our study, 59 cases of alveolar ridge, severe atrophy of elderly people with complete denture repair, to discuss the stability of the denture.
