Michael C. DiTolla, DDS, FAGD

To achieve the highest level of quality in the fit, function and esthetics of a dental restoration, accurate and comprehensive transference of the patient’s oral anatomy, both prepared and natural, to the dental laboratory is imperative.

In this presentation, Dr. Michael DiTolla uses nine cases examples taken from recent episodes of Chairside Live to discuss techniques to adhere to, as well as red flags to be wary of, that can help to ensure pleasing and predictable results for the final restoration. Participants who view this presentation will acquire valuable clinical information on various preparation and impression topics, including:

  • Advantages of digital scanning for determining the sufficiency of a prep
  • Benefits and uses of reduction copings
  • Retaining vertical dimension of occlusion throughout comprehensive restorations
  • Pros and cons of restorative materials in the anterior
  • Best practices for hiding tetracycline staining in the anterior
  • One-step vs. two-step polyvinyl impression techniques and when to use each
  • Capturing vital organic structures in a polyvinyl impression
  • Effectively re-bonding a detached all-ceramic restoration
  • Reasons to adopt the Two-Cord Impression Technique
  • Levels of wear on opposing dentition by restorative materials

Summary

In the pursuit of a functionally and esthetically pleasing outcome to a restorative case, a clinician’s precise and robust communication with the dental laboratory is of paramount importance. By adhering to a regimen that promotes consistent preparations and comprehensive impressions, the dentist can ensure the highest probability of clinical success and patient satisfaction with the fit, form and function of the final restoration.

In this presentation, Dr. Michael DiTolla uses several case examples featured on episodes of Chairside Live to promote the methods and techniques that provide the laboratory with the maximum information necessary to deliver the quality and predictability he and his patients crave.
