Chairside Live – Case of the Week Compendium 13: Prep and Impression Techniques VIII

Prep and Impression Techniques VIII - Dental CE Course
Launch Course

Course Objectives (2 CE Credits)

Michael C. DiTolla, DDS, FAGD

In restorative dentistry, the functional and esthetic success of a case largely relies on the clinician’s ability to communicate accurate information about the patient’s intraoral situation to the laboratory. With a well-informed dental technician working in lockstep, general practitioners can more efficiently and effectively pursue a wide range of options and technologies in order to ensure the ideal treatment plan for the patient.

In this presentation, Dr. Michael DiTolla uses a series of case examples taken from episodes of Chairside Live to discuss his preferred methods for taking consistently accurate impressions, as well as various restorative technologies that provide predictable outcomes to unique clinical circumstances. Participants who view this presentation will acquire useful information on various case treatment topics, including:

  • Requisite elements of a quality VPS impression
  • Efficacy of the hydraulic & hydrophobic impression technique
  • Using an electrosurge around zirconia dioxide and lithium disilicate restorations
  • Making use of distal extension hinges on partial dentures
  • Working with a CDT to design esthetic clasps for partial dentures
  • Provisionalizing anterior implants during osseointegration
  • Custom abutments vs. stock abutments for molar implant restorations
  • The clinical protocol for an implant overdenture on Locator® attachments (Zest Anchors; Escondido, Calif.)
  • Die-spacer usage in a CAD/CAM workflow
  • Adjusting full-contour zirconia after it has been sintered
  • Microleakage in zirconia vs. PFM restorations


With the rapid pace of technological advancement in restorative dentistry, a clinician working with a well-informed dental technician has more tools and methods than ever before to achieve a case outcome that is both esthetically pleasing and functionally reliable.

In this presentation, Dr. Michael DiTolla uses several case examples featured on episodes of the weekly web series Chairside Live to discuss various techniques and innovations dentists can employ to ensure each treatment plan is tailored to the unique clinical situation with which the patient presents, providing the greatest opportunity for case 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.
