Abstract

The objective of this paper is to inform on the indications, appearance and advantages offered by each category of materials used in CAD / CAM technique for different prosthetic restorations.Modern techniques in restorative dentistry include CAD/CAM systems and materials that can be CAD/CAM processed. It is very important to know the physical-chemical properties and the indications of these materials to translate the patient’s wishes to reality providing the ideal restoration. There are a variety of CAD/CAM materials to choose from, all designed to provide efficient restoration design and production. We can choose from available materiales including glass ceramics, nano ceramics, zirconia, hybrid ceramics, BioHPP, in blocks or disks form. Keywords: CAD/CAM technology, CAD/CAM materials, properties, indications

Highlights

In dental medicine, the largest development of CAD / CAM systems occurred in the 1980s
BioHPP Depending on the CAD / CAM system, the list of materials that can be CAD/CAM processed may be wider or narrower, some materials requiring milling in wet environment, others in the dry or even dry-wet environment
Zirconium dioxide and methyl polymethacrylate can be milled in the wet environment

Summary

Introduction

The largest development of CAD / CAM systems occurred in the 1980s. Indications in dentistry areas: Anterior and posterior crowns, bridges with max. Indications in dentistry areas: metalo-ceramic restauration try-in, crowns and bridges obtained by the casting technique, restoration model obtained by pressing technique, digital wax-up The CAD CAM wax from Kulzer is available in three colors, with different hardness (from hard, to elastic), the gray one is indicated for the digital wax-up technique and the crown layouts in the front area, the blue one is indicated for the crown layout.
