To ensure patient comfort during the procedure, local anesthesia is administered. Afterward, the tooth is isolated using a rubber dam or other isolation techniques. Isolation provides a clean and dry environment, facilitating precise tooth preparation.
3. Occlusal Reduction
The occlusal reduction is the first step in tooth preparation. It involves reducing the occlusal surface of the tooth to create sufficient space for the ceramic restoration. The amount of reduction required depends on various factors, including the material used, the desired restoration thickness, and the occlusal scheme.
4. Axial Wall Preparation
Next, the axial walls of the tooth are prepared. This involves creating uniform and parallel surfaces that provide adequate retention and resistance form for the restoration. The taper, depth, and convergence of the axial walls must be carefully considered to ensure proper seating of the final ceramic restoration.
5. Margin Design
The margin design is a critical aspect of tooth preparation. It determines the esthetic outcome, marginal fit, and longevity of the restoration. Different margin designs, such as chamfer, shoulder, or feather edge, may be chosen based on the specific case requirements.
6. Finishing and Polishing
After completing the tooth preparation, it is essential to finish and polish the prepared surfaces. This step ensures smooth margins, reduces roughness, and enhances the esthetics of the restoration. Proper finishing and polishing also contribute to the longevity of the ceramic restoration.
