What Material Are CEREC Crowns Made Of?
CEREC crowns, also known as ceramic restorations, have become increasingly popular in the field of dental restoration due to their numerous advantages. One of the most frequently asked questions about CEREC crowns is: what material are they made of? This article aims to provide a comprehensive overview of the materials used in CEREC crowns and their implications on the quality and longevity of the restoration.
CEREC crowns are primarily made of dental porcelain, a ceramic material that has been widely used in dental restorations for many years. Dental porcelain is known for its excellent biocompatibility, meaning it is well-tolerated by the body and does not cause any adverse reactions. This material is also highly durable, making it suitable for long-lasting restorations.
The porcelain used in CEREC crowns is a type of high-strength ceramic that can withstand the forces exerted by chewing and biting. This high-strength porcelain is capable of mimicking the natural appearance and translucency of tooth enamel, providing a natural-looking restoration that blends seamlessly with the surrounding teeth. The porcelain is also non-porous, which means it does not absorb stains or discolorations, maintaining its aesthetic appeal over time.
In addition to dental porcelain, some CEREC crowns may also incorporate a dental resin material. Dental resin is a type of plastic that is used to bond the porcelain to the tooth structure. This resin material helps to improve the overall strength and longevity of the restoration by providing additional support to the porcelain. Dental resin is also biocompatible and does not cause any adverse reactions.
The process of creating a CEREC crown involves the use of computer-aided design (CAD) and computer-aided manufacturing (CAM) technology. This technology allows for the precise creation of a custom-fitted crown that is tailored to the specific needs of each patient. The CAD software generates a 3D model of the patient’s tooth, and the CAM software then uses this model to guide the creation of the crown using the selected material.
In conclusion, CEREC crowns are primarily made of dental porcelain, a high-strength ceramic material that provides excellent biocompatibility, durability, and aesthetic appeal. Some crowns may also incorporate dental resin to enhance their strength and longevity. The use of CAD and CAM technology ensures that each CEREC crown is custom-fitted to the patient’s tooth, resulting in a precise and effective restoration.
