PATTERN RESIN LS Introduction Contemporary materials, equipment and techniques enable dental technicians to manufacture high precision, aesthetic restorations – and naturally they prefer procedures, which are clear, easy to learn and safe to apply. In this context, accessory materials, which may at first glance appear unimportant, have in fact become absolutely indispensable. Dental prostheses are as individual as the patients.

PATTERN RESIN LS Physical Chemical properties Working time (23° C) Setting time (23° C) Flexural strength (37 °C, after 10 min) Polymerization shrinkage after 30 min Polymerization shrinkage after 24 h 2-3 min 4 min 63 MPa 0,36 % 0,37 % Powder: Liquid: composition Polymethylmethacrylate Polyethylmethacrylate Dibenzoyl peroxide Methylmethacrylate 2-Hydroxyethyl-Methacrylate Brush Technique – Packaging The 1-1 package of Pattern Resin LS contains everything you need for the brush technique: 2 mixing
Brush Technique – Step by Step 1. Mix powder and liquid: Dispense adequate amounts of powder and liquid into the respective mixing cups. 7. Repeat the above procedure to cover the whole surface with a thin layer of Pattern Resin LS. Tip: The pipette helps to dispense the exact amount of liquid. Tip: As fresh Pattern Resin LS adheres perfectly to already polymerized material separate small dots can easily be connected. 2. Slightly moisten the brush. 8. Even where high precision is required, e. g.
PATTERN RESIN LS Brush Technique – Step by Step 13. Place the pattern back on the primary crown. 19. Heating-up is carried out according to the schedules given in the instructions for use. Cast in the usual manner. 14. Prepare the wax-up using an appropriate inlay wax. Check occlusion, contact area and contour as usual. 20. Deflask in the usual way and clean the cast metal surface with glass beads. 15. The wax-up is ready for connection of the sprues. 21.
Implant Restorations Some examples for the use of Pattern Resin in implantology: Case 1 1. Step-by-step build-up of an implant suprastructure with Pattern Resin LS. 3. The implant analogues have been fixed with Pattern Resin LS and cast-on titanium tubes screwed into the analogues prior to manufacture of the superstructure 2. Suprastructure with integrated horizontal screw threads. Further crown buildup will be carried out with modelling wax. 4.
Electroforming PATTERN RESIN LS Restorations Core build-up Core build-up of a molar crown, prior to preparation. In connection with electroforming technology Pattern Resin LS has been successfully applied in several indications: 1. Electroformed die made of Pattern Resin LS, with stainless steel screw as a removal aid 2. AGC® electroformed coping after gold deposition. Telescopic 3. Removal aid made of Pattern Resin LS, for easy removal of the metal coping to avoid deformation.
Investing and casting Mixing ratios: When investing Pattern Resin LS workpieces, always use a higher proportion of investment liquid than with wax patterns. For details please refer to the instructions for use of the respective phosphatebonded investments. Modelations: All Pattern Resin LS workpieces should be covered with a thin layer of wax to avoid deterioration of the investment surface during heating-up.
