What is CAD/CAM

This chapter introduces the iTero digital impression system as a companion to the T-Scan Occlusal Analysis System. Occlusion as a component of aesthetic dentistry is discussed, and how the aesthetic case is aided by T-Scan force control at insertion. The chapter explains that brittle adhesive restorations cannot be evaluated occlusally prior to bonding. Combined with the spatial errors inherent with impression material setting and stone cast articulation, obtaining reliable interocclusal spatial relationships with adhesive restorations can be compromised. Alternatively, the iTero system accurately captures preparation shapes and the opposing interocclusal relationships, which eliminate typical, non-digital cast articulation errors. These clinical realities are illustrated in a10-unit porcelain veneer Case Report, where the iTero system and the T-Scan system are employed together. Finally, recommendations are made that Dental Medicine move towards digital impression making and accept the importance of the T-Scan system in occlusion to improve the standard of patient care.
