Veneers, It can improve the aesthetics and function of a smile and protect the tooth surface from damage. It is able to protect. There are two main materials used in the production of a veneer: composite and dental porcelain. There are different types. A composite veneer can be placed directly in the mouth in a way that creates a shape. or produced indirectly by a dental technician in a dental laboratory and then It can usually be bonded to the tooth using resin cement. Generally, completely. adolescent patients who will need a more permanent design as they grow older It is used in treatment. The lifespan of a composite coating is approximately four years. This is 25 In contrast, a porcelain veneer can only be produced indirectly. A full crown is a restoration that covers all coronal tooth surfaces. It is defined as follows: Laminate veneers are thin layers that only cover the surface of the tooth. It is generally used for aesthetic purposes. 2 CAD / CAM dentistry is used for dental restorations, especially crowns and crown layers. veneers, inlays and onlays, fixed dental prostheses, dental implant-supported restorations, the design and creation of dental prostheses, including dentures and orthodontic appliances It is a field of dentistry and prosthetics that uses CAD / CAM to develop designs.

The final restoration involves layering ceramics in multiple stages to create new ceramics. It can be produced by adding clay and baking it in a kiln. These methods are both time-consuming. This leads to both bone loss and energy loss. The resulting restoration pattern, appearance, and Because the aesthetic qualities depend entirely on the experience and skill of the practitioner, 30 It leads to unpredictable consequences. 3 In conclusion, all the problems mentioned above make innovation in the relevant field imperative. has brought.
