由于丙烯酸树脂不易和金属基托粘结,因而使这种耐用而且舒适的设计受到限制。作者介绍一种经过酸蚀使丙烯酸树脂粘结于金属基托的重衬技术。材料和设备:重讨所需的一般材料、4%硝酸(酸蚀剂)、18%盐酸(清洗液)、粘蜡、20号绝缘铜丝、0.036时的不锈钢丝、蒸馏水、一台电子酸蚀装置(译注:一般牙科实验室用于树脂粘合固定修复体酸蚀金属的装置即可)。市售的硝酸溶液,每100毫升含硝酸71
This durable and comfortable design is limited by the fact that the acrylic resin is not easily bonded to the metal base. The authors describe a rework technique for acid-bonding acrylic resins to metal substrates. MATERIALS AND EQUIPMENT: General materials required for the study, 4% nitric acid (acid etch), 18% hydrochloric acid (cleaning fluid), sticky wax, 20 gauge copper wire, stainless steel wire at 0.036, distilled water, Erosion device (Annotation: General dental laboratory for resin bonding prosthesis metal corrosion repair device can be). Commercial nitric acid solution, containing nitric acid per 100 ml 71
