Answer :
To fabricate a dental prosthesis means to create an artificial device designed to replace missing teeth and restore oral functions. The fabrication process involves using materials such as metals, ceramics, and polymers, along with techniques like molding, casting, and CAD/CAM technology to achieve a custom fit and aesthetic result.
Dental prostheses, including crowns, bridges, dentures, and implants, are crafted to replace missing or damaged teeth, improving both functionality and appearance. The process begins with a detailed assessment and impression of the patient’s oral cavity, ensuring a precise fit.
Several materials are utilized in the fabrication of dental prostheses:
Metals: Alloys like gold, palladium, and nickel-chromium are used for their strength and durability, particularly in the substructures of crowns and bridges.
Ceramics: Porcelain and zirconia are favored for their aesthetic qualities, mimicking the natural appearance of teeth and providing a strong, biocompatible option.
Polymers: Acrylic resins are commonly used for dentures due to their lightweight and ease of customization.
The fabrication techniques include:
Molding and Casting: Traditional methods involve creating a mold from the patient's mouth and then casting the prosthesis in the chosen material.
CAD/CAM Technology: Computer-Aided Design and Computer-Aided Manufacturing allow for digital impressions and precise milling of prostheses, enhancing accuracy and reducing production time.
3D Printing: Emerging as a modern approach, 3D printing enables the creation of highly detailed and customized prosthetic components quickly and efficiently.
These advanced techniques and materials ensure that dental prostheses are not only functional but also aesthetically pleasing, enhancing the patient’s comfort and confidence. By combining traditional craftsmanship with modern technology, dental professionals can deliver prosthetic solutions tailored to the specific needs of each patient.
