Comparison between Provional CAD/CAM and Handmade Crowns

Provisional restorations are used as an intermediate stage for short or long-term placement on teeth between the time of tooth preparation until the definitive indirect restorations are fabricated and placed. The demand for tooth-colored restorations has increased significantly in recent years due to improved techniques and patient demand. Therefore using various new restorative materials which have good mechanical properties are essential for both provisional and definitive restorations. The emergence of computer-aided design/computer-aided manufacture (CAD/CAM) technology in dentistry has allowed the use of different materials successfully. Using these systems to fabricate fixed restorations has gained popularity in comparison to conventional techniques.In addition this technology permits shaping of materials with high precision that cannot be carried out easily via a traditional method to make a dental restoration and this technology now includes the fabrication of provisional restorations.
