Chairside Live – Case of the Week Compendium 12: Prep and Impression Techniques VII

Prep and Impression Techniques VII - CE Course
Launch Course

Course Objectives (2 CE Credits)

Michael C. DiTolla, DDS, FAGD

While care in preparation and accurate impressions remain key staples for achieving a successful dental restoration, more nuanced contributors like accurate shade-matching and bonding protocols can make the difference between an esthetic, long-lasting prosthesis and a displeased patient.

In this presentation, Dr. Michael DiTolla uses a series of case examples taken from episodes of Chairside Live to divulge the methods and technologies he uses to ensure both the visual and functional aspects of a restoration are amply addressed. Participants who view this presentation will acquire clinical information on topics including:

  • Confirming sufficient reduction using digital oral scans
  • Comparing digital intraoral scanners
  • Prescribing restorative shades that lie between VITA® (Vident™; Brea, Calif.) classical values
  • Communicating tooth shade to the laboratory through photographs
  • Determining the best material and appropriate arch for a successful splint
  • Achieving an esthetic outcome on a single central incisor restoration
  • Selecting an adhesive for veneer placement
  • Restorative materials fit for low-retention preparations
  • Products and methods for effectively bonding full-contour zirconia
  • Using multi-unit implant abutments to attain adequate prosthetic draw
  • The restorative protocol for a zirconia full-arch implant prosthesis
  • Using a provisional restoration as a template for an identical final prosthesis


In restorative dentistry, a patient’s satisfaction is commonly contingent on the esthetics of the final restoration and the lasting functionality of the prosthesis. Effectively communicating the shade of adjacent dentition to the lab, as well as using adhesion techniques appropriate to the prescribed material, will help ensure that a well-prepared tooth and a consummate impression will not be undermined in the final steps of the procedure.

In this presentation, Dr. Michael DiTolla uses several case examples featured on episodes of Chairside Live to discuss his preferred methods for achieving a lifelike resolution, confirming that the same care taken in tooth preparation is also taken to address these equally important, yet easily overlooked, aspects of a dental restorative case.

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.
