An adhesive composition for a denture base relining material which comprises an organic solvent containing no halogen atoms such as ethyl acetate, ethyl formate or acetone, a polymer such as a copolymer of methyl methacrylate and ethyl methacrylate, and a radical polymerizable monomer such as tetramethylolmethane tetramethacrylate; and a curable composition which comprises a radical polymerizable monomer, an organic peroxide such as benzoyl peroxide, a tertiary amine compound such as diethyl-p-toluidine or dipropyl-p-toluidine, and a hydroxycarboxylic acid such as malic acid or citric acid.
The adhesive composition for a denture base relining material does not contain a halogen-atom-containing organic solvent whose harmful effect has been pointed out. Further, the composition has satisfactory adhesive properties and good operability and causes no degradation in the appearance of a denture base even if it sticks to an area on the surface of the denture base other than a contact area. The dental curable composition is widely used as dental materials having little surface unpolymerized layer and good curability, e.g., dental cement, a composite resin, a resin for crown and a denture base relining material.
一种用于义齿基托衬垫材料的粘合剂组合物,它包括不含卤素原子的有机溶剂,如乙酸乙酯、甲酸乙酯或丙酮;聚合物,如甲基丙烯酸甲酯和甲基丙烯酸乙酯的共聚物;以及可自由基聚合的单体,如四甲基丙烯酸甲酯;和一种固化组合物,它包括一种可自由基聚合的单体、一种有机过氧化物(如过氧化苯甲酰)、一种叔胺化合物(如二乙基对甲苯胺或二丙基对甲苯胺)和一种羟基羧酸(如苹果酸或柠檬酸)。
用于义齿基托衬垫材料的粘合剂组合物不含已指出其有害影响的含卤原子有机溶剂。此外,该组合物具有令人满意的粘接性能和良好的可操作性,即使粘在义齿基托表面接触区以外的区域,也不会造成义齿基托外观的下降。这种牙科固化组合物被广泛用作表面未聚合层少且固化性好的牙科材料,例如牙科粘合剂、复合树脂、牙冠用树脂和义齿基托衬垫材料。
