Chairside Live – Case of the Week Compendium 1: Prep and Impression Techniques

Dental CE Course – Prep Impression Techniques
Launch Course

Course Objectives (2 CE Credits)

Michael C. DiTolla, DDS, FAGD

When preparing teeth and taking conventional impressions for dental restorations, the techniques and materials a clinician uses have a significant impact on the accuracy of the impressions sent to the dental laboratory and subsequent fit of the finished restorations.

In this presentation, Dr. Michael DiTolla uses a series of case examples taken from recent episodes of Chairside Live to discuss his preferred techniques for preparing teeth and taking consistently accurate impressions, while highlighting potential pitfalls to avoid. Participants who view this presentation will acquire useful clinical information on various prep and impression topics, including:

  • The Reverse Preparation Technique
  • Controlling tooth reduction when preparing teeth
  • Benefits of using a depth-cutting system during tooth preparation
  • Choosing the right restorative material for your preparation technique
  • Types of impression materials
  • Tips for taking ideal impressions
  • Techniques for avoiding impression errors
  • Two-Cord Impression Technique
  • Alternative to packing retraction cord
  • Full-arch vs. double-arch trays
  • Impression guidelines for bridge restorations

Summary

In restorative dentistry, a successful outcome is largely dependent on a dentist's ability to adequately prepare teeth and take accurate impressions. Taking great impressions for well-fitting restorations can be simple if a dentist chooses the correct impression tray, achieves adequate retraction and uses an impression material that clearly captures and communicates every detail of the preparation to the dental laboratory.

In this presentation, Dr. Michael DiTolla uses several case examples featured on recent episodes of Chairside Live to discuss his preferred techniques for adequately preparing teeth and taking error-free impressions, outlining numerous do's and don'ts for clinicians to keep in mind when performing these procedures.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
