Dental crowns are one of the most commonly practiced procedures among dentists all over the world. They fall under the category of dental prosthesis and materials which enhance the aesthetics of the patient's mouth.
Dental crowns have the positives in that they provide strength as well as aesthetic features, whichever is required. Usually, anterior (front) teeth require more aesthetics than posterior (back) ones, whereas the posterior teeth require more strength for masticatory (chewing) processes than that required by anterior teeth. This is one of the most commonly practiced procedures for missing teeth. Endodontic treatment, like root canal treatment famously known as RCT, is the procedure in which the tooth structure becomes weaker as the particular tooth is devitalized. The blood supply and nerves are discontinued from the tooth. Therefore, it is suggested by the dentists to get a dental crown placed. This helps the tooth regain its strength and function like before. In this way, dental crowns are a boost for the patients who look for a dental treatment plan which keeps their dentition complete and makes them look the same, in fact better than before.
For the procedure of placing a dental crown on the patient’s tooth or on the dental implant , a few steps have to be performed prior to carrying out the procedure. A part of the particular tooth (i.e. Enamel) is removed from the tooth and the tooth is left with the dentin on it. Then the tooth is made compatible with the crown to be placed. Previously a lot of time was consumed by the dentists to get a crown made of the size which suits ideal for the patient and the condition of his oral cavity. Many times, it happens that there is very less tooth structure to support the traditional crown on it. At that time, restorations are the one which help in providing proper support to the crown once it is placed on the tooth structure. As technology has advanced nowadays, CAD/CAM technology is used and is improving to take images of the required crown as per the information it takes. Then the ideal crown for the patient is made with the help of the image. It takes a single appointment to get the crown made for the patient using this technique. Moreover, the dental crowns made nowadays has got a long lasting time period. The average time period is 8-10 years. So patients prefer dental crowns to get these benefits. Full gold crown and porcelain-to-metal fused crown are the major types of dental crowns across the world.
