The benefit of the more compact scanner is ease of use especially in smaller mouths and tight to reach places (think distal of the upper 2nd molars). The CEREC Omnicam has the smallest scanner head and weighs approximately 315 grams. As scanning technology plateaus, the scanning speeds of these three competitors seems to have equalised. The scanning image produced by the Emerald appears to be a lower resolution and is not as high definition as the Omnicam or TRIOS. It does need a little more attention to pick up interproximal areas however. Intra-orally it is as quick as the other two and seems to be one of the smoothest scanning experiences of the three. The recently released Planmeca Emerald is also a high-speed scanner. It is by far the most visually appealing scanner on the market. It is an efficient scanner with a realistic HD scanning aesthetic. Regarding scanning speed, the 3Shape TRIOS is as fast if not faster than the CEREC Omnicam. The Omnicam is still one of the best scanners on the market which is remarkable considering it has been on the market for over five years, while the competitors are much newer. Sometimes scanning very lustrous surfaces such as gold crowns can slow down scanning as they can require you to go over the area multiple times (or use a scan spray) but in reality, this is a non-issue and happens to every scanner. The CEREC Omnicam provides a smooth and seamless scanning experience with few if any areas that can be faulted. Although early in the game the CEREC Omnicam trumped all competitors in scanning speed, now other CAD/CAM systems have caught up.
