This report describes the clinical and technical aspects in the oral rehabilitation of an edentulous patient with knife-edge ridge at the mandibular anterior edentulous region, using implant-retained overdentures. The application of computer-aided design and computer-aided manufacturing (CAD/CAM) in the fabrication of the overdenture framework simplifies the laboratory process of the implant pr...

This study deals with the development of a new CAD/CAM system for fabricating the holes whose cross sections are changing variously. A cross section of a machined hole is generally constant. To solve the problem, a new device had developed which could create cross section’s changing holes by means of electrical discharge machining. However, it was impossible to put the device into practical use...

Dr. Duret first introduced the CAD/CAM concept to dentistry in 1973 in Lyon, France in his thesis entitled Empreinte Optique, which translates to Optical Impression. The concept of CAD/CAM systems was further developed by Dr. Mormann, a Swiss Dentist, and Mr. Brandestini, who was an electrical engineer. 8 CEREC was the first commercially available digital impression system for use in the field ...

BACKGROUND Anxiety and cardiac autonomic modulations (CAM) were thoroughly investigated in coronary artery disease (CAD) and cardiac syndrome X (CSX) patients worldwide, but not among Sudanese with similar pathology. AIMS To compare levels of anxiety and CAM between Sudanese patients with CSX and CAD. MATERIALS AND METHODS Anxiety was evaluated in 51 CAD and 26 CSX patients using Taylor Man...

. The objective of STEP is to provide a neutral data model capable of describing product data throughout the life cycle of a product that is independent from any particular software application or computer platform. AP203, AP214, AP224 promote the integration of CAD/CAM system. Now STEP-NC, a new extension of STEP, is being developed. A truly integrated CAD, CAPP, CAM and CNC paradigm is now in...

STATEMENT OF PROBLEM Information is lacking about the fatigue resistance of computer-aided design and computer-aided manufacturing (CAD-CAM) tooth-colored implant custom abutment materials. PURPOSE The purpose of this in vitro study was to investigate the reliability of different types of CAD-CAM tooth-colored implant custom abutments. MATERIAL AND METHODS Zirconia (Lava Plus), lithium disi...

The availability of 3D dental model scanning technology, combined with the ability to register CBCT data with digital models, has enabled the fabrication of orthognathic surgical CAD/CAM designed splints, customized brackets, and indirect bonding systems. In this study, custom lingual orthodontic appliances were virtually designed by merging 3D model images with lateral and posterior-anterior c...
