金属和瓷修复体包括边缘一般是在尽量准确地复制的代型上制作,而要达到更好的准确性是直接在牙齿上制取蜡型,它比前者更准确、吻合。本法是用可见光固化资料以直接和间接混合法制作金资冠。首先按常规预备牙体,制取一个具有活动代型的精确模型及对颌模,按(牙合)记录上(牙合)架,制作金属帽状冠。若冠的唇面金属边缘已接触或覆盖于台肩上,应适当磨薄磨短使其刚好接触或稍离台肩。然后上不透明瓷于金属表面,烧结后在口内试戴调改合适,取下清洁干燥备用。将牙面清洁干燥后,用Spectrum分离剂涂布牙面,戴上帽状冠使之充分就位稳定,再涂上肩台瓷(颈 Metallic and porcelain restorations, including the edges, are typically made on a prototype that reproduces as accurately as possible, and to achieve better accuracy, the wax is made directly on the tooth, which is more accurate and consistent than the former. This law is to use visible light curing materials to direct and indirect production of gold crown. First of all, according to the conventional preparation of the tooth, the preparation of an accurate model of active generation and jaw mode, according to (occlusal) recorded on the (occlusal) frame, the production of metal cap crowns. If the crest of the crown metal edge has been touched or covered on the shoulder, should be appropriate grinding mill so short it just touch or slightly off the shoulder. Then opaque porcelain on the metal surface, after sintering in the mouth to try to change the appropriate, remove the clean dry reserve. After the tooth surface is cleaned and dried, the surface of the tooth is coated with the Spectrum separating agent and the crown is put on to make it fully in position and stabilized. Then, the shoulder porcelain
