Diagnosing Failed Impressions
Taking an accurate impression for a fixed dental prosthesis is a challenge that requires a strong understanding of the anatomy surrounding the finish line, the materials used, and the correct use of the impression tray. Recent studies within a commercial dental laboratory showed that 86% of crown and bridge impressions contained at least one detectable error, and 55% contained a critical error related to the finish line.
In this latest edition of CDA Oasis Live, Dr. Nate Lawson, Head of Biomaterials at the University of Alabama School of Dentistry, introduces his own article Diagnosing a Failed Impression: Common Errors and How to Overcome Them.
In conversation with Dr. John O’Keefe, Director of Knowledge Networks CDA, Dr. Lawson addresses some of the common challenges in making an accurate impression, including distortions and dealing with subgingival margins, and shares valuable tips on how to consistently get the best possible outcome.
We hope you find the conversation useful. We welcome your thoughts, questions and/or suggestions about this post and other topics. Leave a comment in the box below or send us your feedback by email.
