ABSTRACT Aim This paper describes a case of a rehabilitation involving Computer Aided Design/Computer Aided Manufacturing (CADCAM) system in implant supported and dental supported prostheses using zirconia as framework. Background The CAD-CAM technology has developed considerably over last few years, becoming a reality in dental practice. Among the widely used systems are the systems based on zirconia which demonstrate important physical and mechanical properties of high strength, adequate fracture toughness, biocompatibility and esthetics, and are indicated for unitary prosthetic restorations and posterior and anterior framework. Case description All the modeling was performed by using CAD-CAM system and prostheses were cemented using resin cement best suited for each situation. Conclusion The rehabilitation of the maxillary arch using zirconia framework demonstrated satisfactory esthetic and functional results after a 12-month control and revealed no biological and technical complications. Clinical significance This article shows the important of use technology CAD/CAM in the manufacture of dental prosthesis and implant-supported.

SUMMARY Background: This case report describes the complete full-mouth treatment of hypocalcified amelogenesis imperfecta (AI) by chairside computer-aided design and computer-aided manufacturing (CAD/CAM). Case summary: After several years of interrupted dental care, a 17-year-old female patient presented with pain and also esthetic and functional discomfort. With loss of enamel and dyschromia affecting all teeth, the diagnosis was hypocalcified AI. Affected tissues were eliminated, gingivectomy with laser was performed, an indented jig was used to record the centric relationship during optical impressions, and 28 full ceramic crowns were created by chairside CAD/CAM in four sessions. The patient reported rapid pain relief and an overall improvement of well-being. Conclusion: AI sequelae can be treated promptly and conservatively with chairside CAD/CAM, obtaining esthetic and functional results.

Great emphasis has been attached to the achievement of productivity and producibility benefits through the application of computer-aided design and computer-aided manufacturing (CAD/CAM) technologies. To ensure the achievement of these benefits, it is important that the end user have appropriate software and be able to use it to his advantage. The proper procurement, customization, installation, training, and implementation of software can play a significant role in the effectiveness of CAD/CAM.

Abstract Background Contemporary dentistry is advancing toward computer-aided design/ computer-aided manufacturing (CAD/CAM) technology. But the budding dentists are unaware about the advancement. This survey aims at detecting the level of awareness among the undergraduate students and then correlating those results to modify the future curriculum. Objective The study aims (1) to assess the awareness among the dental undergraduate students and (2) to correlate the level of awareness among the third years, final years, and interns. Sample Selection Study sample consist of 300 students (third year students, final year students, and interns) of A. B. Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India. The information of the survey was collected with the help of a questionnaire. Results More than 70% of the students were aware about the basic functioning of CAD/CAM unit and approximately 74% of the students were unaware about the materials used to fabricate the prosthesis using CAD/CAM technology.

SUMMARY Objective: To evaluate the significance of reduced axial wall height on retention of adhesively luted, all-ceramic, lithium disilicate premolar computer-aided design/computer-aided manufacturing (CAD/CAM) crowns based on preparations with a near ideal total occlusal convergence of 10°. Methods: Forty-eight recently extracted premolars were randomly divided into four groups (n=12). Each group received all-ceramic CAD/CAM crown preparations featuring axial wall heights of 0, 1, 2, and 3 mm, respectively, all with a 10° total occlusal convergence. Scanned preparations were fitted with lithium disilicate all-ceramic crowns that were luted with a self-etching resin cement. Specimens were tested to failure at a 45° angle to the tooth long axis with failure load converted to megapascals (MPa) based on the measured bonding surface area. Mean data were analyzed using analysis of variance/Tukey's post hoc test (α=0.05). Results: Lithium disilicate crowns adhesively luted on preparations with 0 axial wall height demonstrated significantly less failure resistance compared with the crowns luted on preparations with axial wall heights of 1 to 3 mm. There was no failure stress difference between preparations with 1 to 3 mm axial wall height. Conclusions: Under conditions of this study, adhesively luted lithium disilicate bicuspid crowns with a total occlusal convergence of 10° demonstrated similar failure resistance independent of axial wall height of 1 to 3 mm. This study provides some evidence that adhesion combined with an ideal total occlusal convergence may compensate for reduced axial wall height.
