Fabricating the Transil matrix
Separate the laboratory silicone with a thin coat of Vaseline to prevent the two silicone materials from sticking to each
other. Insert the Transil cartridge into the dispenser, mount a new mixing tip and apply Transil to the die and pontic in a
single step. Transil should be applied in a layer thickness of approx. 3 to 6 mm to obtain sufficient stability. The setting
reaction may be accelerated by using a hot air dryer. After the material has set, smooth out the exterior surface and form it
into a conical shape to enhance the passage of light. Subsequently, remove the Transil matrix from the die.
Apply a thin coating of Vaseline to the laboratory silicone and then apply Transil.
Smooth out the exterior surface of the Transil matrix and form it into a conical shape.
Tip:
A Vectris foil may be used to smooth out the outer surfaces while the matrix material is still soft.
Tip:
In order to facilitate the flowing off of the Vectris matrix matrial, small spillways may be cut into the palatal and labial
portions of the laboratory silicone after the Transil matrix has been removed.
