Chairside Live – Case of the Week Compendium 21: Prep & Impression Techniques XI

Chairside Live - Prep & Impression Techniques XI
Launch Course

Course Objectives (3 CE Credits)

Michael C. DiTolla, DDS, FAGD

Despite common elements shared across all tooth preparation cycles regardless of final prosthesis type, restorative dentists who neglect to allow particulars like material type, adhesive chemistry and stump shade to inform their techniques risk delivering prostheses inadequate in form or function. In this presentation, Dr. Michael DiTolla uses a series of case examples taken from episodes of the web series Chairside Live to discuss ways in which to anticipate impending issues and ensure the final restoration drives the method of treatment-plan execution. Participants who view this presentation will acquire useful clinical information on topics such as:

  • The foundation of quality dentistry
  • Trends in restorative material usage
  • The effects occlusal clearance and retentive properties have on material options
  • Reduction requirements for multiple-veneer cases
  • Avoiding additional prep appointments with lab-made reduction copings
  • Gingival retraction techniques for capturing margin details
  • Bridge impression pitfalls to avoid
  • Choosing the right combination of abutment and restorative material for the esthetic zone
  • Unesthetic restorations caused by translucent restorations over dark stumps
  • Best practices for shade-matching success
  • Bonding to a zirconia crown using resin-based cements
  • Advantages of cementing restorations over bonding them
  • Methods for post-restorative desensitization


As technologies that promise better fit, form and function of a final prosthesis continue to advance, patient satisfaction is likely to rest on a clinician’s ability to deliver these more natural restorations. Allowing the end result to inform the preparation and impression methods can help ensure that every step is tailored toward this common goal. In this presentation, Dr. Michael DiTolla uses several case examples featured on episodes of Chairside Live to discuss his preferred techniques for executing a treatment plan with an eye toward the delivery of a final restoration that has the highest chances of clinical success.

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.
