Today’s dental technician is presented with the wider variety of restorative materials than ever before. In the case of all-ceramic reconstruction, the material choice for strong yet highly esthetic restorations is often one of lithium disilicate vs. veneered zirconia; however we have to be aware that neither material is suitable to fit all cases. Each material has its indications and mechanical qualities that will determine its appropriate uses. In the course we will try to discern which substructure material provides the best restorative options for each individual patient.
Additionally, we will attempt to define the benefits and limitations of CADCAM systems and see the real possibilities they offer including better productivity and versatility as standardized quality. We will also discuss the use of zirconia on implants and how we can implement e.max CAD or e.max press in this type of restoration.
Objectives:
- To specify the indications and contraindications of zirconia and lithium disilicate as restorative materials.
- Assimilate the necessary knowledge for the manipulation of both materials and thus obtain maximum mechanical and esthetic potential
- Controlling the structure volume depending on the type of material.
- Understand the differences between ceramic stratification on zirconia and lithium disilicate: how many layers, colors and thicknesses.
- Assimilate color taking protocol with the patient and in the laboratory: step by step, the light and the materials.
- Understand the ceramic layering on a standard color such as A1, A3 or B2: optimal color results without the patient.
In the hands-on portion of the course, we will fabricate two crowns that will try to solve the two possibilities we face daily:
- Standard color crown (A3): Schematic of ceramic layering using single firing technique. Analysis of the morphology and texture of this based on the model. Surface finished with polished texture and mechanical gloss.
- Patient-colored Crown: Shade determination on the participant, color map and texture analysis. Layering using an intermediate firing technique. Surface finished with polished texture and mechanical gloss.
