Crown and Bridges Treatment in Pune
Crowns & Bridges is the dental restoration for the tooth/teeth which are damaged, decayed or lost. Crowns and most bridges are fixed prosthetic devices used for your dental restoration. Both crowns and bridges are cemented onto existing teeth or implants which can be removed only by a dentist. It is not like other removable devices such as dentures, which can be taken out and clean daily by you.
To restore a damaged tooth back to its original position we use crown whereas bridge is used to replace one or more missing teeth. The restorations are cemented onto the teeth and are as referred to as fixed. We use local anesthetic for both the procedures During the preparation of the teeth, a badly decayed tooth may require “build up” with a special restorative material. With a fixed bridge, the prosthesis will span the area of a missing tooth, known as pontic, while the two or more adjacent supporting teeth are called abutments. An impression is taken of the prepared area and a temporary crown or bridge is placed.
Why is Dental Crown Needed?
A dental crown may be needed in the following situations:
- To protect a weak tooth (for instance, from decay) to prevent it from breaking or in order to hold together parts of a cracked tooth
- To restore an already broken tooth or a tooth that has been severely worn down
- To cover and support a tooth with a large filling when there isn’t a lot of tooth left
- To hold a dental bridge in place
- To cover a dental implant
- To cover mis-shapened or severely discolored teeth
Different Types of Dentall Crown
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- to- metal (PFM) crowns
PFM can be matched in colour 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. 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 if your gums recede. It is essential to maintain good oral hygiene in order to prevent this. These crowns can be a good choice for front or back teeth.
3. Metal Crowns
The metals used in crowns is an alloy of nickel and 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. Metal crowns are usually placed in posterior teeth to avoid being seen when the patient smiles.
4. All-Resin Dental Crowns
4) All-Resin dental crowns are made out of Composite, the same material used to do tooth-coloured 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 Dental Crown: These are made of acrylic. Temporary crowns can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory. They do not last very long in the mouth and are subject to rapid breakdown.
