          imaging but it wasn’t enough to tip the scales for every clini-
        
        
          cian to say, “Hey, this is something I can dowith ease.”
        
        
          The strength of theOmnicam is that it allows for imaging
        
        
          of quadrants, half arches and full arches with ease and,
        
        
          with streaming capture and full color. The clinician simply
        
        
          has to wave the camera over the teeth to capture the areas
        
        
          to be recorded. Frankly, users new to in-office CAD/CAM
        
        
          will wonder why it was done any other way — not real-
        
        
          izing the amount of research-and-development dollars
        
        
          that were invested to create the Omnicam.
        
        
          With the Omnicam, we can do multiple restorations,
        
        
          but without resorting to the software manipulations and
        
        
          tricks of the past. Simply image the area that you want, and
        
        
          restore that area using the 4.0 software.
        
        
          Treatingmultiple anterior teethwith theCEREC 1might
        
        
          have been similar to trying to win the Tour de France on a
        
        
          tricycle. With the Omnicam, it has now become a breeze.
        
        
          Wave the camera, image your pre-op wax-up, image your
        
        
          preps and have the software copy the wax-up. It is simple
        
        
          and certainly within the capabilities of a clinician to tackle
        
        
          multiple restorations without headache.
        
        
          Certainly, the material limitations of the past have also
        
        
          been lifted. We currently have the ability to mill feld-
        
        
          spathic porcelain, leucite reinforced, resin and lithium
        
        
          disilicate, as well as bisacryl materials.
        
        
          This leads to the question of what role will the CEREC
        
        
          have now? And, more specifically, what role will the
        
        
          Omnicam play in the smile-design process? We have the
        
        
          materials and the software to create provisional resto-
        
        
          rations. Anything that can fit into a 55 mm block can be
        
        
          milled with ease. Simply design the restorations and mill
        
        
          with the material of your choice. This can be used to
        
        
          create long-term provisional restorations that are now
        
        
          milled chairside and offer strength higher than traditional
        
        
          bisacryl restorations.
        
        
          But what about the milling of esthetic mock-ups for
        
        
          esthetic cases? No doubt if provisional restorations can be
        
        
          milled, thenwhy notmock-ups?With the increased imaging
        
        
          ability of the Omnicam, capturing full-arch virtual models
        
        
          will lead to an increased use of the system for additional
        
        
          chairside applications. Mock-ups, esthetic temporaries,
        
        
          splits-to-open vertical dimensions are all future possibilities
        
        
          now that we have imaging without restrictions.
        
        
          Imagine being able to capture not only the teeth, pre-op
        
        
          wax-up and preps, but use the Omnicam to capture the
        
        
          extra oral structures that will help you design the resto-
        
        
          rations. Or imagine capturing the lip position to see if the
        
        
          restorations that you have designed actually fit in the arch-
        
        
          form and look good in the patient’s mouth.
        
        
          TheOmnicamcouldpotentiallybeusedas adiagnostic tool
        
        
          instead of just a restorative tool. Because the systemcaptures
        
        
          and creates the models in full color, this might mean that for
        
        
          new-patient exams, instead of impressions with alginate, we
        
        
          now capture intraoral scans on new patients, giving us the
        
        
          ability to not only diagnose a whole host of issues but also
        
        
          collaborate with our specialist colleagues to share the data
        
        
          and arrive at a comprehensive treatment plan. Patients and
        
        
          clinicians are able to review intraoral findings in full color
        
        
          that mimic the situation as it appears exactly in the mouth.
        
        
          Instead of doing digital imagingwith specialized software for
        
        
          anterior restorations, perhaps the softwarewill have features
        
        
          that will allowusers to perform those tasks natively.
        
        
          The evolution of in-office CAD/CAM  has been tremen-
        
        
          dous. Yes, it’s taken close to three decades to come to a point
        
        
          where one doesn’t have to wonder how CAD/CAM works
        
        
          —
        
        
          we just
        
        
          
            know
          
        
        
          that it works. Fromever-increasing capabili-
        
        
          ties, we know that from inlays, onlays, crowns, abutments,
        
        
          bridges, veneers and many more indications, the system
        
        
          works and it works well. The only question left to answer
