PATTERN RESIN LS is a self-curing, general-purpose acrylic resin used for making patterns for fabricating copings, post and core build-ups, lingual and palatal bars, implant attachments, adhesion bridges, clasps, telescoping crowns and certain pre-soldering techniques. This product is formulated to provide a perfect fit. It is ideal for dentists and laboratories who perform difficult restorations due to the fact that it sets quickly with minimal shrinkage, allows both direct and indirect pattern making, and leaves no residue after burnout.

To make the pattern of:

Tapered coping for telescopic crowns and other telescope crowns
Inlay, palatal and lingual bar, connector and clasp
Maryland bridge.

Temporary splint for soldering

Direction to Use

Step 1.Powder and liquid preparation Dispense adequate amounts of powder and liquid into each rubber cup.

Step 2. Building the coping (for secondary crown patterns of tapered crowns or telescopic crowns)

a) Moisten the tip of the brush with the liquid and pick up a small amount of powder.
b) Deposit this mixture on the crown and progressively build up the secondary crown pattern by repeating the procedure. In this case, no separating medium is required, but when working on a stone model, GC Acro Sep, GC Multi-Sep or Vaseline should be used as separator. – Clean the brush with liquid after use or during the work if necessary.

Step 3. Checking the internal surface of the pattern After the resin has set (3 min. at 23°C /73°F), remove the pattern carefully from the internal crown and check the margin and the internal surface .

Step 4. Fine adjustment

a) Return the pattern to the internal crown and make a uniform thickness (0.3-0.4 mm) by using a bur.
b) Remove the pattern and check the thickness with the measuring device.

Step 5. Waxing veneer and Cut out

a) Perform the wax-up with inlay wax.

Note: There is no need to clean the surface of the pattern resin with a cleaning agent before waxing.

b) Cut out the veneer for the facing .
c) Place the retention beads.

Step 6. Investing, Burning out and Casting For a single crown, all procedures can be performed in the usual manner. For a larger pattern, hold at 250°C (482°F) for 1 hour before raising to the final burn out temperature.
