One Session Veneers
Veneers in One Session Using Cad-Cam Technology
Porcelain dental veneers offer attractive alternative to time-consuming orthodontics procedures to reshape the teeth and making them uniform and straight and look whiter as well. Porcelain veneers are shell shaped thin covers that are fixed permanently onto your teeth. It takes just two sittings to get perfectly fitting veneers that enhance your facial features by covering the discolored or malformed teeth.
There are different processes for making the porcelain veneers. Pressed veneers are created from the wax design, where a porcelain ingot is heated and forced into void formed by the wax sample. Refractory model veneers are made from a traditional veneering technique. The layering technique gives good aesthetic properties of shade and translucence. Platinum foil veneer has several advantages and limitations and is not employed commonly now. CAD CAM porcelain veneers are made with help of computer based program for both the design and fabrication of veneers.
The process of fabricating custom built porcelain veneers has been made simple, precise and fast by the introduction of CAM CAD technology. The veneers are manufactured to the required shape with the help of a computer program both in design and fabrication. The program uses a veneer template made in 3D and cuts the veneer in the required shape precisely. It is possible to stain and have layered porcelain build to get the best shape.
Compared to traditional techniques of dental restoration using porcelain veners, employing CAD CAM techniques can simplify many steps involved. Instead of traditional procedure of taking impressions, it is possible to get the image with the help of a hand held device that records the images digitally. Basically there two techniques that can be employed for CAD CAM restoration; a single visit chair side technique or chair side visit along with laboratory procedure with CAD CAM.
Clinic with dental laboratory equiped with CAD CAM facility has the following advantages.
- Restorative procedure requires a single visit.
- No need to make impressions.
- No need of temporary restoration
- No separate laboratory costs
- No need of mechanical modeling or die pouring
- Offers less risk potential of tooth sensitization
- Very little margin of error
But it is observed that the finished restorations done under this procedure have inferior esthetics as compared to laboratory fabricated porcelain veneers.
Integrated chair side and laboratory CAD CAM technique requires two sittings. Here the dentist can make the traditional impression to take the scan or directly scan the structure of teeth and send the image to the laboratory for fabrication. If the latter method is chosen, the patient does not require undergoing the process of taking impression and also a source of possible errors is eliminated. There are different techniques for transmission for sending the images to the laboratory like CEREC Connect and iTero scans which accept the series of digital images and use them for fabricating the veneers. One of the advantages of this technique is that the dentist is able to optimize the design for best aesthetic effects by focusing on artistic ceramics. Of course, it requires two visits for the sitting but the time for each sitting is reduced.
CAD CAM porcelain veneers offer best solutions for dental restoration and help to get the veneers with minimum errors and time required for the whole procedure.
