Outcomes of the Course

This course will be a hands-on workshop for fabricating #9-11 three unit bridge with the use of Zirconia frame. Centrals, laterals and canines constitute a large portion of a smile, which can affect the entire facial expression dramatically both positively and negatively. Therefore, numerous factors need careful consideration in the treatment process of these areas. For example, unlike in a single crown restoration, the bridge requires finer attention in the balance of aesthetics and mechanical function. The workshop will allow discussion time with the audience to answer any questions and to explain procedural steps in details.
