A dental crown is a restoration that is placed over an affected tooth to amend its shape, size or strength. Crowns are typically used to cover a heavily filled, decayed or broken tooth as well as to provide strength after a root canal treatment.
For many years, traditional metal-based crowns have been used to strengthen or rebuild teeth. Today, porcelain crowns and pressed ceramic crowns, such as E-max crowns, are now an effective, aesthetically-pleasing option which are completely metal-free. They are made to match the exact colour, texture and translucency of your natural teeth. E-max crowns have improved strength due to the way they are constructed in the laboratory.
They are pressed to full contour with no layering providing maximum strength with no weak spots or risk of porcelain fracture. Plus the fitting surface of the crown is etched and bonded to the prepared tooth which has the effect of making the tooth and crown combine into one structure leaving a very low risk of fracture.
