Aim: To demonstrate the procedure for mounting the maxillary cast in the mean value articulator using a newly designed mounting device. Background: Fabrication of dental prostheses, especially by indirect technique, requires the use of an articulator. Apart from reducing the chair side time it has numerous advantages. However, accurate mounting of the cast in the articulator is mandatory to avoid fabrication errors. The techniques currently in use are either difficult to master or require costly equipment. This article describes a new technique for mounting the cast in a mean value articulator using a custom-made mounting device. Technique: The newly designed mounting device consists of a U-plate, an anterior rod, and two posterior rods. The mounting device is fixed to the articulator so that the anterior rod is inserted into the hole in the incisal pin and the posterior rods rest on the posterior reference bar. This places the U-plate at the level of the reference plane of the articulator. The maxillary cast with occlusal rim is placed over the U-plate and mounted using type II gypsum. The mandibular cast is later mounted in the articulator using the interocclusal record. Conclusion: As the wax mount is not necessary for this technique; the newly fabricated mounting device reduces the chances of error during the mounting of the maxillary cast that could occur during the conventional procedure. Clinical significance: Routine procedures commonly used were based on arbitrary methods (wax mounting) with a high chance of error, while other devices were expensive and selective in purpose. Therefore, the need for more accurate and precise methods are required instead.
