CROWNS & BRIDGES

Normally the crowns/caps are placed over the fractured, discolored, and root canal treated teeth but in today’s world of advanced cosmetic dentistry the caps are frequently used to improve smile of the patients.

Bridges are used to replace the missing tooth by reducing the adjacent firm and healthy teeth and placing caps over them which support the missing tooth pontic.


Different types of crowns :

Whatever be the crown selected, it should resemble the form of natural tooth. In anterior teeth it should match the color of adjacent tooth and in posterior teeth; it should be made of hard material so that it can be able to withstand all the forces. The material of the crown should be biocompatible with the surrounding structures. And most importantly it should be with in the range of patient i.e. it should be economical.

1 ) All-ceramic or all porcelain dental crowns provide the best natural color match than any other crown type and may be more suitable for people with metal allergies. All-ceramic crowns are a good choice for front teeth..

2. Porcelain fused metal crowns can be color matched with our natural teeth. They very much resemble natural tooth color shade. However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown’s porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown’s porcelain can show through as a dark line, especially at the gum line and even more so if your gum’s recede. These crowns can be a good choice for front or back teeth.

3) Metal Crowns . The metals used in crowns include gold alloy, nickel or chromium. Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. Some people like the color of the crown especially gold crowns as it might symbolize wealth status. Metal crowns are usually placed in backed teeth to avoid being seen when the patient smiles.

4) All resin dental crowns made out of composite material, the same material used to do normal color fillings in our mouth. They are less expensive than other crown types. However, they wear down over time and are more prone to fractures than porcelain-fused-to-metal crowns.

5) Temporary dental crown. Temporary crowns are made of acrylic, stainless steel and some even use gold . Temporary crowns can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory. It is only used as a temporary alternative as they do not last very long in the mouth and are subject to rapid breakdown
