佩戴全口义齿的患者常因为牙槽骨吸收严重而导致粘膜压痛及固位不良。使用软衬材料可以缓解患者的上述症状,并提高咀嚼效率。但现临床常用软衬材料性能上存在一定的缺陷,主要表现为弹性难以长久维持、易与基托剥脱和真菌易于粘附等问题。对于如何解决上述问题,许多学者对现有材料的改进和新型材料的研发做了大量的基础研究和大胆探索。本文就义齿软衬材料性能的研究进展作一综述。
Patients who wear complete dentures often cause mucosal tenderness and poor retention due to severe alveolar bone resorption. The use of soft lining material can alleviate the above symptoms of patients and improve chewing efficiency. However, there are some defects in the properties of soft liner materials commonly used in clinical practice, which are mainly manifested in that the elasticity is difficult to maintain for a long time, the exfoliation of the base and the easy adhesion of the fungus are easy to occur. How to solve the above problems, many scholars do a lot of basic research and bold exploration on the improvement of existing materials and the development of new materials. This article reviews the research progress of denture lining materials.
