This paper presents a methodology for implementing the feature recognition system for achieving the Computer Aided Design/ Computer Aided Manufacturing (CAD/CAM) integration goals. The Featurebased modeling is being used to model the solid models. The features being considered in this paper is hole form feature. The input of the feature recognition system is the Standard for the Exchange of Pro...

PURPOSE To gain insight into the methodology of different computer-aided design-computer-aided manufacturing (CAD-CAM) applications for the reconstruction of cranio-maxillo-facial (CMF) defects. METHODS We reviewed and analyzed the available literature pertaining to CAD-CAM for use in CMF reconstruction. RESULTS We proposed a classification system of the techniques of implant and cutting, d...

BACKGROUND The present study introduces the design and fabrication of a simple surgical guide with which to perform genioplasty. METHODS A three-dimensional reconstruction of the patient's cranio-maxilla region was built, with a dentofacial skeletal model, then derived from CT DICOM data. A surgical simulation was performed on the maxilla and mandible, using three-dimensional cephalometry. We...

This paper presents results of a case study undertaken to understand the effect of computer assisted teaching methodology on learning effectiveness in a laboratory environment. The effects of computer assisted instructions on different levels of cognition of individual learners, as described by Bloom’s Taxonomy have been evaluated. For this students in mechanical engineering subject area were e...

Objective This study evaluated marginal accuracy of full-arch zirconia restoration fabricated from two digital computer-aided design and computer-aided manufacturing (CAD-CAM) systems (Trios-3 and CS3500) in comparison to conventional cast metal restoration. Materials and methods A stainless steel model comprising two canine and two molar abutments was used as a master model for full-arch rec...
