Fabrication of an individual tray

• Allow Profibase to reach room temperature before use.
• Mark margins for the individual tray on the plaster model. If necessary, use a space maintainer. If space maintainer is not necessary, insulate the plaster model.
• Remove protective foil, mold plate onto the model and cut the desired rim as marked. A handle can easily be shaped from the excess material.
• Profibase is then polymerised on the model with a standard light unit (halogen or UVA light). Depending on the thickness of the tray, polymerize the reverse side for 3 – 5 min.
• A longer polymerization time improves the physical properties of the material. Therefore, prolonged time of polymerisation if necessary.
• The individual tray is immediately ready for use and can be worked upon without delay. A slight inhibition layer, eventually caused by oxygen, can be easily removed with a tissue moistened with alcohol.

Fabrication of a base plate

• Mark the margin of the planned prosthesis base on the plaster model.
• Block out undercuts as usual. Isolate the model thinly with alginate isolation.
• Carefully place a plate of Profibase onto the model, adjust the rims with a penknife and polymerise the model with base plate for 5 min in a standard halogen or UVA light unit.
