Build Up of Crown

 

A. Opaque Dentin

 

1. Select appropriate shade of Opaque Dentin and make a flat strip by pressing with a stainless steel spatula on a glass slab.

2. Apply to abutment extending to the cervical margin. Avoiding air bubbles or pockets is essential. Repeat as necessary for 40% to 70% of crown thickness.

3. Light cure for 2-4 minutes.

 

Notes: If not enough Opaque Dentin is used, the end result may appear too gray due to the lack of an opaque background. Use up to 70% Opaque Dentin for greater opacity. Increase chromaticity with darker shades, color intensifier/modifier and/or stain characterizers.

 

Using larger flat strips of material for application will eliminate air bubbles and will control the thickness of the material.

 

If the material is applied too thickly, light will not be able to penetrate resulting in uncured areas.

 

B. Dentin

 

1. Make a flat strip by pressing with a stainless steel spatula on a glass slab.

2. Apply directly onto Opaque Dentin layer and create anatomical features. Incorporate intrinsic stains as required at this juncture prior to solidification.

3. Light-cure for 2 minutes for material thicknesses of 2-3mm.

 

 

Keys to Success

  • Refrigerate DiamondCrown™ materials during storage.
  • Allow material to reach room temperature prior to being expressed from tubes.
  • Reverse the screw plunger after sufficient material has been expressed.

 

C. Enamel

 

1. Make a flat strip by pressing with a stainless steel spatula on a glass slab.

2. Apply directly to Dentin layer. Shape morphology and apply contacts and margins.

3. Continue with intrinsic characterization and light-cure for 2 minutes for material thickness of 2-3mm.

 

 

D. Incisal

 

1. Apply selected Incisal directly onto Enamel.

2. Characterize by using different shades.

3. Light-cure for 2 minutes.

4. Shape morphology and adjust occlusion.

5. Observe the proper emergence profile of the mechanically polished IAC using Polishing Kit (Part # C416).

6. Facial view of final IAC restorations.

7. Profile view of final IAC restorations.

 

 

 

 

 

 

 

 

 

 

 

 

Keys to Success

  • Avoid ridge lap restorations.
  • Polish mechanically.
  • Never use glaze material.
