(36min) Pre-Preparation Contouring To Achieve Ideal Archform With IPS Empress Veneers (© 2005)

Course Objectives

This case presentation provided an opportunity to demonstrate how to achieve the results that the patient desired, without the use of orthodontics. Clinical considerations from treatment planning to the placement of laboratory-fabricated (IPS Empress®) porcelain veneers is provided. Participants that complete the presentation will acquire useful information in many areas, including the following:

  • Considering the patient’s objectives and a clinical assessment of the case.
  • The advantages of pre-preparation planning and contouring are considered and
    implemented.
  • Using a putty/wash matrix to quickly fabricate provisionals is discussed in an
    informative sidebar about a diagnostic wax-up’s many uses; fabrication and finishing
    of temporaries on the patient is demonstrated
  • Reverse prep, blending depth cuts, refining gingival margins, cord packing,
    impression techniques and many other practice tips and observations are
    provided.
  • Veneer try-in and the steps that are involved in placing and cementing veneers are
    provided.
  • Bonding technique tips: etching; seating; initial (tack and wave) curing; clean-up;
    methods of removing resin cement; final cure.
  • Finishing, presenting and analyzing before-and-after results.

    • Summary

    An over-the-shoulder video clinical presentation of a 10-unit IPS Empress® veneer case provides a close-up look at a solution involving pre-preparation planning and contouring to achieve desirable results. A practical demonstration of understanding the patient’s objectives, a candid evaluation of the treatment possibilities, and achieving a desired clinical result—involving the creation of a more ideal archform without orthodontics—is presented. The pre-preparation considerations and the techniques that are presented will help practitioners more confidently meet patients’ expectations. A straightforward execution of the necessary steps—based on some basic placement and bonding principals that are presented—provides a useful approach to successfully placing and bonding porcelain veneers.

    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 judgement regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
