Explanation:
The question asks what is fabricated, cemented, and adjusted by dental professionals. The correct answer is a) Dental crowns. Dental crowns are tooth-shaped "caps" that are placed over a tooth to restore its shape, size, strength, and to improve its appearance. The fabrication process involves creating a custom crown that closely matches the natural color and shape of the patient's teeth.
This is often done in a dental lab after the dentist has taken an impression of the tooth that needs the crown. Cementation is the process by which the crown is attached to the tooth using a special dental adhesive, ensuring that the crown stays securely in place. Adjustment involves the dentist reshaping and polishing the crown during the fitting process to ensure a perfect fit with the bite and surrounding teeth, providing both functionality and aesthetics.
This contrast to dental implants, which are surgically inserted into the jawbone, temporary restorations, which are used temporarily until a permanent solution is ready, and orthodontic appliances, which are devices used to correct teeth and jaw alignment. Dental crowns are fabricated, cemented, and adjusted by dental professionals. They are custom-made caps placed over damaged teeth to restore their size, shape, and function.
These crowns can be made from various materials like porcelain, metal, or a combination of both. They are essential in restoring a tooth's structure and protecting it from further damage. Regular check-ups and adjustments by dental professionals ensure that the dental crowns fit properly and provide long-lasting support for the affected tooth.
