What processes does Ultra aesthetic zirconia go through to become teeth?

Ultra aesthetic zirconia undergoes several processes to transform into dental restorations, such as crowns, bridges, or veneers. These processes typically involve the following steps:

Digital scanning or physical impressions: The patient's teeth or prepared tooth structure is scanned digitally using an intraoral scanner or traditional physical impressions are taken. This captures the precise shape and dimensions of the teeth to be restored.

Computer-aided design (CAD): The digital scan or physical impression is then imported into CAD software, where the dental technician or dentist designs the desired restoration. The software allows for precise customization, taking into account factors like tooth shape, size, occlusion, and aesthetics.

Milling or milling center: Once the design is finalized, the CAD data is sent to a milling machine or milling center. The milling machine uses diamond-coated burs to carve the ultra aesthetic zirconia block into the desired shape and size based on the CAD design. This process is often done using computer-aided manufacturing (CAM) technology.

Sintering: After milling, the partially shaped zirconia restoration is subjected to a sintering process. Sintering involves placing the restoration in a furnace and heating it to a high temperature, typically around 1,450 to 1,500 degrees Celsius. This process helps to densify the zirconia and achieve its final strength and durability.

Finishing and glazing: Once the restoration is sintered, it undergoes further finishing processes. This may involve removing any excess material, refining the shape, and polishing the surface to achieve a smooth and aesthetic finish. In some cases, a glazing process is also performed to enhance the aesthetics and provide a glossy appearance.

Try-in and adjustments: The finished ultra aesthetic zirconia restoration is then tried in the patient's mouth to assess the fit, occlusion, and aesthetics. Any necessary adjustments or modifications are made at this stage to ensure proper fit, function, and aesthetics.

Cementation: Once the restoration is approved, it is permanently cemented onto the prepared tooth structure using a dental adhesive or resin cement. The cementation process ensures a secure and long-lasting bond between the zirconia restoration and the tooth.

Throughout these processes, dental professionals closely follow the manufacturer's guidelines and recommendations for working with ultra aesthetic zirconia to ensure the best possible outcomes in terms of aesthetics, fit, and durability.
