英文回答：
Fixed Restorations Fabrication Process.
1. Preoperative Evaluation.
Comprehensive examination to determine the need for fixed restorations.
Assessment of patient's oral health, bite relationship, and occlusion.
Evaluation of existing restorations and any potential risk factors.
2. Treatment Planning.
Determination of the type of fixed restorations required (e.g., crowns, bridges, inlays, onlays)。

Selection of appropriate materials and designs.
Estimation of treatment duration and cost.
3. Tooth Preparation.
Removal of decay or damaged tooth tissue.
Creation of a proper shape and size for the restoration.
Ensuring adequate retention and stability.
4. Impression Making.
Taking an impression of the prepared tooth and surrounding tissues.
Using an appropriate impression material to accurately capture the details.
5. Fabrication of Provisional Restoration (Optional)。

Creating a temporary restoration to protect the prepared tooth.
Providing patients with a more comfortable and aesthetically pleasing solution during the fabrication process.
6. Model Fabrication.
Pouring the dental impression into a model material.
Creating a stone model that accurately represents the patient's teeth.
7. Wax-Up and Sprue Placement.
Forming the desired shape and size of the restoration on the model using wax.
Attaching sprues to the wax pattern for the casting
process.
8. Investing and Casting.
Encasing the wax pattern and sprues in an investment material.
Heating the investment to burnout the wax.
Casting the molten metal into the mold to create the metal framework.
9. Finishing and Polishing.
Removing the investment material from the cast framework.
Contouring and polishing the framework to achieve the desired shape and surface finish.
10. Porcelain Application and Firing.
Applying porcelain to the metal framework in layers.
Firing the porcelain in a dental oven to achieve the desired strength and aesthetics.
11. Glazing and Polishing.
Applying a thin layer of glaze to the porcelain surface.
Polishing the glazed surface to enhance its smoothness and shine.
12. Cementation.
Bonding the fixed restoration to the prepared tooth using a dental cement.
Ensuring a strong and secure bond.
13. Occlusal Adjustment.
Checking the occlusion and making any necessary adjustments to ensure proper bite function.
14. Postoperative Care.
Providing patients with instructions on oral hygiene and care of the fixed restorations.
Scheduling regular follow-up appointments for monitoring and maintenance.
