Learning Objectives:

Upon completion of this course, participants should be able to do the following:

  1. Understand the concept of Crownless Bridge Works (CBW®) as a bridge facility without conventional crown preparations.
  2. Become familiar with the necessary step-by-step clinical and laboratory procedures to fabricate and place Crownless Bridge Works.
  3. Discuss the practicality of the Crownless Bridge Work technique.
  4. Understand the concept of a CBW® framework.
  5. Describe treatment situations in which the CBW® technique could be used in conjunction with conventional treatment modalities.
  6. Answer frequently asked questions about the CBW® technique.


Abstract:

The Crownless Bridge Work method is a combination of dental techniques based on more than 20 years of clinical experience in the field of both adhesive dentistry (etched bridges) and bridge-anchoring systems. Both techniques have been used and documented widely over the past few decades. In general, the CBW® bridge system combines the advantages of both techniques. It addresses two prevalent problems in the replacement of missing teeth using fixed bridge prostheses. First, a large percentage of edentulous areas in the posterior region of the mouth are not restored. Second, patients are reluctant to have healthy teeth ground down in order to fit a conventional bridge. CBW® presents a new and exciting alternative to the conventional fixed bridge replacement. This technique uses a combination of pin-anchoring and adhesive fitting and has a number of advantages over resin-bonded bridges and conventional bridges. This course will introduce the technique, describe the step-by-step clinical and laboratory procedures necessary to produce the CBW® appliance, and describe situations in which the technique can be used in conjunction with conventional treatments.
