Fabricating a Matrix with Silicone Lab Putty

This video demonstrates the process of fabricating a matrix using silicone lab putty on a dental cast. These matrices can be used to create reduction guides or provisional matrices used during a restorative procedure.

Fabrication Steps:

1. Measure out the base and catalyst precisely.
2. Mix the base and catalyst thoroughly until a uniform color has been achieved.
3. Form the silicone over a stone cast of a wax-up or the patient’s existing dentition.
4. Create even thickness of material over all of the surfaces.
5. Create a smooth labial surface and flat occlusal surface to facilitate intraoral use of the matrix.
