A ceramic-pressed-to-metal restoration (PTM) combines the merits of the casting and the press techniques. Fabrication of a PTM starts with wax-up and casting for the metal framework 11) . Following the opaque porcelain application to the metal framework, a complete contour wax pattern is made and burnt out 11) . The ceramic is then pressed into the room created by burnout of the full contour wax pattern 11) . Therefore, a PTM exhibits better marginal adaptation than a J Korean Dent Sci.

Even though a conventional metal ceramic restoration is widely in use, its laboratory procedure is still techniquesensitive, complex, and time-consuming. A ceramic-pressed-to-metal restoration (PTM) can be a reliable alternative. However, simplified laboratory procedure for a PTM is still necessary. The article is to propose a technique that reduces time and effort to fabricate a PTM with the aid of computer-aided design, computer-aided manufacturing and selective laser sintering technologies.
