Your teeth are capable on withstanding enormous forces of mastication, but over a period of time your tooth structure might wear off and your tooth might get damaged, cracked and weakened by caries. When your tooth gets weak, its ability to withstand those forces will decrease, which will eventually lead into the fracture of your tooth resulting in extensive pain which usually requires extraction depending on the level of the fracture.
To prevent this from occurring Dental crown should be placed on weakened tooth, but what’s a crown ?
A crown or dental capping is a fixed prosthodontic’s which is cemented (applied) over existing teeth structure to prevent fracture of the remaining tooth. The crown is also used after root canal treatment, the reason behind that is the root canal access the cavity or the cavity created after removing of caries and decay and finding the root canals, this process will lead into weakening of the tooth, but it depends on the amount of tooth structure removed during this process.
So are crowns only used to protect the remaining tooth structure?
Other than protecting a tooth which has already been weakened either due to carries or a preexisting large restoration, dental crowns are also used to :
Should crowns always be metal to withstand the forces of mastication ? and what are the kinds and types of crowns ?
Well, no. Crowns are not only metal here at the best dental clinic in Dubai we provide our patients with almost every type of crowns present, these are :
Here in the Dental Department of Dr. Rami Hamed Center we deal with the best dental labs in Dubai, whom are able to replicate not only the color but also the exact shape of the tooth being crowned
The procedure of making a crown usually takes two visits depending on the type of crown you choose , most of the crown are done in two visits but the Porcelain fused to metal may require a 5 minute extra this visit as our Prosthodontist will assure the proper fitting of metal on your prepared teeth and that there is no presence of a gap between the metal and the teeth, because if present this gap will act as a harbor of Bacteria which will eventually lead into formation of caries that will destroy the remaining tooth structure that the crown was mad to protect, This procedure will be done to the other types of crowns but on the same day of delivery.
Here after the diagnosis and clinical assessment being done by our prosthodontist’s he will start with tooth preparation in which he will remove amount to tooth structure up to 2.5 mm all around the teeth and the amount removed depends on the type of crown, this preparation is done in order to provide enough thickness of material over the tooth, and the thickness should be enough to withstand the forces applied on the teeth, while doing so a finish line will be created, the finish line is where the crown edge meets the tooth, the final procedure done in the first visit is taking an impression which will accurately show all features on the prepared teeth, before dismissing the patient he will be provided with a temporary crown made up of acrylic to prevent teeth sensitivity and pain in non-root canal treated tooth. Our prosthodontist in this visit will also choose the color of the crown.
