Dental zirconia, also known as zirconium dioxide, has become increasingly popular in dentistry due to its excellent biocompatibility and aesthetic properties. It is a ceramic material that can be used for various dental restorations, such as crowns, bridges, and implants.
To use dental zirconia, the following steps are typically followed:
-
Diagnosis and treatment planning: The dentist will thoroughly examine the patient's oral health and discuss the desired outcome with them. This includes determining if dental zirconia is suitable for the specific case.
-
Tooth preparation: If the patient requires a crown or bridge, the affected tooth or teeth must be prepared. This involves removing a thin layer of enamel to make room for the restoration.
-
Impression taking: An impression of the prepared teeth is made using dental putty or digital scanning technology. This impression serves as the mold for creating the zirconia restoration.
-
Shade selection: The dentist and patient will choose the appropriate shade for the zirconia restoration to match the natural color of the surrounding teeth.
-
Digital design and milling: Using computer-aided design (CAD) software, the dentist designs the shape and size of the zirconia restoration based on the patient's specific needs. The design is then sent to a milling machine that carves the zirconia block into the desired shape.
-
Sintering and coloring: The milled zirconia restoration is placed in a high-temperature furnace for sintering, a process that strengthens the material. Afterward, the restoration may be colored or stained if necessary to achieve a more natural appearance.
-
Try-in and adjustments: Once the zirconia restoration is ready, it is checked for fit, comfort, and aesthetics. Any necessary adjustments are made to ensure proper alignment and occlusion.
-
Cementation: The final step is cementing the zirconia restoration onto the prepared tooth or teeth using dental adhesive. The dentist carefully bonds the restoration in place, ensuring a secure and long-lasting result.
It is important to note that the steps may vary depending on the specific case and the preferences of the dentist. Dentists with experience in zirconia restorations are able to provide patients with high-quality, durable, and aesthetically pleasing dental restorations.
