铸造合金和全瓷等材料被广泛用于牙体、牙列缺损的修复。修复体在口腔环境中行使功能时会发生腐蚀,引起离子析出,造成修复体周围牙龈组织的损害。本文就全冠修复材料的离子析出及其对牙龈成纤维细胞生物学行为影响的研究现状,以及临床常用冠修复材料的性质、优点、缺点及相互之间的比较做一综述。 Casting alloys and all-ceramic materials are widely used in tooth, dentition defect repair. Corrosion occurs when the prosthesis performs its function in the oral environment, causing ion precipitation, causing damage to the gingival tissue around the prosthesis. This review summarizes the current situation of iontophoresis of full-crown healing materials and their effects on the biological behavior of gingival fibroblasts, as well as the properties, advantages, disadvantages and comparisons of commonly used crown-healing materials.
