Abstract
Because residual monomer may cause tissue irritation, we investigated two self-curing acrylic denture-base materials--one a compression type, and the other a pourable material--by means of gas-liquid chromatography. Both exhibited higher residual monomer levels than did heat-cured acrylics, with thick sections having lower values than did thin sections. The pourable material showed lower values than did the compression variety.
摘要
由于残留单体可能会引起组织刺激，我们通过气液色谱法研究了两种自凝丙烯酸义齿基托材料——一种是加压型，另一种是可灌注型。两种材料的残留单体含量均高于热凝丙烯酸树脂，厚截面的残留单体含量低于薄截面。可灌注型材料的残留单体含量低于加压型材料。
