在牙列缺失患者中,牙槽嵴呈刀刃状、低平将甚或消失,复盖粘膜萎缩变薄以及局部存在异常骨突者占有相当比例。对这类患者单凭传统的硬性义齿修复方法进行修复,常常存在着义齿固位不良和粘膜压痛的问题。数十年来义齿软衬材料的开发研究结果表明:以弹性材料作为基托衬里对于解决上述困难有着令人瞩目的前景。本文仅就义齿软衬材料的作用机制、发展种类、实验室性能及临床应用等方面的研究概况作一综述。
In patients with missing dentition, alveolar ridges were knife-shaped, low flat or even disappear, covering mucosal atrophy and thinner as well as the local presence of a significant proportion of abnormal osteonecrosis. Repair of such patients with traditional rigid denture repair often involves the problem of poor retention of the denture and mucocutaneous tenderness. Decades of denture soft lining material development and research results show that: the use of elastic material as the base liner to solve the above difficulties have a remarkable prospect. This article reviews only the research status of denture soft lining materials, such as the mechanism of action, development types, laboratory performance and clinical application.
