Cerec
A powerful technology/system, Cerec is made by Sirona Dental Systems UK. Dentists in UK have used it extensively and consistently for quite a while now and the results have always been fast and convenient. The dentist prepares the tooth through the common procedure for all other applications safe for the use of “dental putty” which is not used but in its place the take an impression of your tooth the dentists will make use of a digital image taken by using a special kind of a camera. The output image will be converted into 3D, a conversion that brings out a computerized form of the tooth, whose appearance is exactly like the real tooth in the computerized image important for guiding the dentist in the design of the new restoration that is required. The image data obtained is sent to an onsite milling machine for fabrication of a new tooth from a high quality ceramic block. Mostly, the complete process takes from six minutes to thirty minutes, depending on the range of the technology used as well as the nature of the tooth being treated.
Currently, there are new makes of machines for example the CEREC MCXL which is capable of milling a crown in six minutes. Once the milling process is over, the dentist proceeds to categorize the tooth by staining so that it matches the shade of surrounding teeth. This is followed by polishing or glazing in a furnace. Cementing of the new restoration into the right position is the last step. The ability to use only one set of anaesthetic injections, plus a short duration of treatment, owing to the powerful machines that have been invented over time are some of the benefits of using Cerec. Overall it is a wonderful treatment with good feedback from patients as well as dentists.
