What is Lithium Disilicate?
Lithium disilicate is a type of glass-ceramic material that is commonly used in dentistry for the fabrication of dental restorations such as crowns, veneers, and bridges. It is known for its exceptional strength, durability, and aesthetic properties, making it a popular choice among dental professionals and patients alike.
Step 1: Preparation
The first step in using lithium disilicate is to prepare the tooth or teeth that will receive the restoration. This involves removing any decay or existing restorations and shaping the tooth to create space for the restoration. The tooth is then cleaned and dried thoroughly.
Step 2: Impression
Once the tooth is prepared, an impression of the tooth is taken using a dental impression material. This impression captures the exact shape and size of the tooth, which will be used to create a custom-made restoration.
Step 3: Shade Selection
Next, the dentist will work with the patient to select the appropriate shade for the restoration. Lithium disilicate is available in a range of shades to match the natural color of the patient's teeth, ensuring a seamless and natural-looking result.
Step 4: Fabrication
Using the dental impression as a guide, the dental laboratory will fabricate the lithium disilicate restoration. This involves milling a block of lithium disilicate using computer-aided design and computer-aided manufacturing (CAD/CAM) technology to create a restoration that precisely matches the shape and size of the patient's tooth.
Step 5: Try-In
Once the restoration is fabricated, it is important to ensure that it fits properly and looks natural in the patient's mouth. The dentist will try in the restoration and make any necessary adjustments to ensure a perfect fit and optimal aesthetics.
Step 6: Bonding
After the try-in, the restoration is ready to be permanently bonded to the tooth. The tooth is cleaned and etched to create a rough surface, which allows for better adhesion. A dental adhesive is applied to the tooth, and the restoration is carefully placed and secured in position.
Step 7: Final Touches
Once the restoration is bonded, the dentist will make any final adjustments to ensure proper occlusion (bite) and aesthetics. The restoration is then polished to a high shine, giving it a natural and lifelike appearance.
Conclusion
Lithium disilicate is a versatile and reliable material for dental restorations. By following these steps, dental professionals can ensure a successful and long-lasting outcome for their patients. If you are considering a dental restoration, be sure to ask your dentist about the benefits of lithium disilicate and how it can improve your smile.
