Matrix Preparation
(enclosed version, non precious alloy)
 
8. Fit the matrix onto the patrix, block out the undercuts and apply a thin wax coat around the sides. Also fill up the drill hole located in the retention (no pin inserted).
 
9. After duplicating, mould the casting pattern by omitting the patrix area. Cast and prepare as usual.
 
10. Set the matrix with inserted retention pin onto the patrix and waxcoat it thin around the sides. Set the casting pattern into place and connect it to the matrix by use of common acrylic.
The matrix is retained mechanically in the denture material.
