Presentation Outline What is CAD CAM Its Introduction into Dentistry CADCAM Dentistry- The Process of Scanning, Designing and Manufacturing Utilization of CAD CAM in the Dental Office and in the Dental Laboratory Comparison of CAD CAM Processes to the Traditional Analog Restorative Techniques Materials used in CAD CAM Dentistry
What is CAD CAM? Computer Aided Design and Computer Aided Manufacturing It is essentially an integration of a software to help design a certain concept, prototype or product and a program which converts that electronic image into a numeric controlled programming language which generates instructions to the machine which makes it. The manufacturing process could be subtractive (Milling) or additive (Printing).
CAD CAM Process
Introduction of CAD CAM in Dentistry Some of the early innovation in CAD CAM dentistry started happening in the 1980s both in the Dental Laboratory and in the Dental Office
The Pioneers in CAD CAM Dentistry Dr. Duret was the first to introduce CAD CAM to dentistry in 1971. He used an optical scanner to image the prepared tooth and then design and mill the restoration Dr Moermann was the first to introduce chairside fabrication of dental restorations using CAD CAM in the early 80s. He is the person behind the most popular CAD CAM system in Dentistry today- CEREC Dr. Andersson developed the Procera system used mainly to fabricate framework copings with CAD CAM in lab settings
CAD CAM WORKFLOW Scanning- Data Acquisition Designing- Modelling Manufacturing- Milling
Optical Scanning- Digital Impressions The Principle of Optical scanning is that a source of laser or structured light is emitted on to the teeth and the surrounding tissues and the data points of the various surfaces are captured by the sensors in the device and the software converts it into a 3D model
Designing- Planning on Digital Models Proprietary 3D rendering software prepares a digital restoration on the created digital model based on the input of information by the dental or laboratory professional
Manufacturing- Milling The process by which the selected dental restoration is milled out of a prefabricated block of Dental material to be used for the restoration
Digital Workflow vs Analog Workflow Digital Process- The New World Dental Office Try In, Seat and Cement the Restoration Tooth Preparation Dental Office Intra Oral Scan and software creates a digital Model Electronic Transmission of Data Ship to Dental Office Dental Lab Design, Mill and Characterize and Process the Restoration Analog Process- Traditional Dental Office Try In, Seat and Cement the Restoration 2nd Visit Tooth Preparation Ship To Dental Office Dental Office Impression with Alginate/ PVS and Make a Model Send to Lab Dental Lab Waxup, Casting, Ceramic Structure characterization and Crystallization

CAD CAM Workflow in the Dental Office- One Visit Dentistry Preparation of the tooth to be restored Isolation Imaging with Intra Oral Scanner Designing the Restoration in the Chairside Software Milling the restoration Characterization and Crystallization/ Sintering of the Restoration Bonding/Cementing of the Restoration
CAD CAM Workflow from Dental Office to Dental Laboratory – Two visit Dentistry Preparation of the tooth being restored Isolation Imaging with the Intra Oral Scanner and Temporization Online Transmission of the Scanned Data to a Dental Lab Lab Designs, Mills, Characterization, Crystallization, Sintering of the Restoration Shipped to Dental Office Restoration Bonded / Cemented in the Dental Office2nd visit

CAD / CAM software, as seen in Production plant ceramic frames which are processed by the milling process, are made in several different shades, for the color corresponding to the requirements of patients, as well as the parameters that determine the high level of aesthetics.

modeling course at ET -WWU designed to expose CAD/CAM technologists to this important CAD domain. It will start by motivating the value of surface modeling in developing key skills that have been identified as essential to the education of a CAD/CAM specialist . This will be followed by an overview of the CAD/CAM curriculum taught highlighting .

CAD / CAM Preparation kit consists of a special assortment of 11 diamond burs for quick, easy and precise preparation of abutment for CAD / CAM restoration. Unique new shapes provide the desired thickness and rounded incisal and cuspal angles in the abutment, that are critical for the precision of the CAD / CAM restoration. .
bricate CAD/CAM blocks (7), however, due to ceramic inherent characteristics as brittleness, low tensile streng-th, and low fracture toughness (8-10), in recent years new composite resin-based blocks have been developed (11,12). Resin composite CAD/CAM blocks seem to have on advantage over ceramic CAD/CAM blocks in
