It can be more difficult to scan the distal of second molars using the Emerald. One thing that stands out is how large the scanning head is, especially when compared to the TRIOS and Omnicam. It has an ergonomic design and is used in pen-grip. It is however the lightest scanner by a large margin weighing approximately 240 grams. The Emerald is the middle of the pack in terms of size. This enables the 3Shape to fit many preferences. Unlike the others, 3Shape comes in many configurations including pen-grip, handle and wireless configurations. It weighs slightly more than the Omnicam at 340 grams. It contains an inbuilt heater, and the scanning head is larger than the Omnicam. The Omnicam scanning head is smaller than its competitors as it has no inbuilt heater.ģShape TRIOS is the largest scanner of the three. 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.
