Fixed Prosthodontics Milan Style – Module 2

From tooth preparation to provisionals, to impression taking

  • What are the criteria for choosing a specific type of preparation?
  • Which burs should be used?
  • What does the dental technician really want from us to make a beautiful and precise crown?
  • How many impression materials is it necessary to have in the office?
  • Which impression technique is best to adopt?
  • Is it time to introduce an intraoral scanner in the office?
  • For what reasons do the temporaries often not fit on the prepared abutments?


Horizontal or vertical finish lines? Is there a universal preparation or should it be diversified? Is the dental preparation for an all ceramic restoration different from that for a metal-ceramic one? Are all metal-free ceramics the same and, therefore, can they accept the same configuration and preparation depth or are there substantial differences?

The correct preparation of a tooth depends on the understanding of many factors: from anatomical and biological aspects to geometrical principles to ensure adequate retention, from those that take into account the structural strength of the material to those that concern cementation.

This course addresses the issue of complete (360°) preparations, clarifying which preparations are indicated in the different clinical situations and demonstrating the step-by-step approach with the recommended burs.


The creation and application of temporary crowns or bridges in resin is an indispensable step of any prosthetic therapy.

These devices play a fundamental role in the development of the final prosthetic project. The speaker will demonstrate how with the temporaries it is possible to condition the healing of gingival tissues, define the volumes and the arrangement of the teeth, test a new anterior guidance, and confirm the needed space for the selected final restorative material.

The speaker will illustrate the most suitable materials for the fabrication and relining in the mouth of provisionals ranging from complete crowns to veneers to minimally invasive preparations, regardless of whether analogical techniques are used or a digital workflow is employed.


To many clinicians, final impression is a very stressful moment of the prosthetic workflow on which they believe they have little or no control.

Every time that an impression is not satisfactory, they do not know whether to blame the material or the technique.

This lecture will illustrate the criteria for the selection of the appropriate impression material on the basis of the clinical conditions displayed by the patient, and the step-by-step technique employed to minimise errors and retakes.

Course Objectives



  • The anatomical considerations that guide the preparation of the teeth: the level of the gingival tissues and the biological width
  • The classical principles of preparations according to the form of retention and form of resistance and those of minimally invasive preparations
  • Which configurations of dental preparations are indicated according to the requirements of the different prosthetic materials and the condition of the tooth
  • The preparation technique in detail: the burs and the instruments used


  • When to use an immediate temporary crown and when one custom made in the laboratory
  • What provisionals are possible with the new CAD-CAM technologies
  • The resins to be used clinically for the relining and modification of the provisionals
  • The technique for the fabrication, application and relining of a provisional shell
  • How to avoid the most common problems when making and applying temporary prostheses


  • Which impression material to select in the various clinical situations
  • When to request an individual impression tray and how it should be made
  • Gingival retraction techniques
  • The techniques for taking the impression of natural teeth
  • The components for implant impressions and the protocols for capturing the position of implants in totally edentulous and partially edentulous arches
  • The indications, advantages and limits of an intraoral optical impression
Pratical Excersises and Demonstrations


Taking a final impression with an intraoral scanner: protocols for natural teeth and implants
