Additionally, the profession is changing rapidly towards using more all-ceramic crowns and fixed prostheses, and ceramic veneers, resulting in tooth preparations that require different characteristics from the past and optimal design for long-term service. Observe the best tooth preparation techniques for all types of crowns and ceramic veneers, compare air and electric handpieces, and carbide burs versus diamond instruments. See ideal indications for shoulders, chamfers, and feather edges for all types of indirect restorations. You can accomplish ideal tooth preparations for crowns and fixed prostheses. These techniques are easy and will provide predictable results.
