04 Remove the putty once it has cured and create a sprue hole with a #8 bur (Fig. C). Eliminate all wax from the putty and the model.

05 Starting with the model at room temperature, use an oven at 235°F to warm the model and mold for 4 minutes. Note: Overheating the model or mold can cause porosity.

06 Load the appropriate Hot Shot Elite injection sleeve with VisiClear material (Fig. D). Set the temperature (446°F) on the digital control panel (Fig. E). Note: Temperature settings and pre-heat/melt times are listed on the side handle of the injection unit.

07 After 4 minutes, extrude a small amount of material prior to injection, then inject the VisiClear material into the putty sprue hole (Fig. F).

08 Allow the VisiClear clasp to cool, then use a sharp blade to cut away the putty (Fig. G).

09 Finish the clasp with conventional burs, then polish using the CDM Dental polishing kit (Fig. H). Fig. I shows the finished clasp.
