This video demonstrates one technique for fabricating an incisal reduction guide. I use incisal reduction guides routinely in my practice both to verify the amount of reduction that I have created for veneers or crowns, as well as to layer incisal composite during a direct composite technique. In addition I use incisal guides on both the lower and upper arch during an equilibration to transfer the new incisal edge position from a work-up. This method will show how to cut the guide out of a full arch silicone matrix made from Flexitime Easy Putty, allowing the other half to be used to create a notebook Guide.
- Fabricate a silicone matrix.
- Remove matrix from model.
- Using a blade cut through from the palate just distal to the canine, facial to the incisal edge.
- Cut just facial to the incisal edge at the depth of the inside of the matrix from canine to canine.
- Pull back on the lingual and finish cutting through any tags of silicone.
