How To Install A Crown On A Tooth

Procedure for Dental Crowns

At least two dental visits are typically needed to prepare a tooth for a dental crown to be placed. The purpose of the first dental visit is to examine and fix the tooth that is to be crowned and create an impression of the tooth so that the crown can be constructed. A temporary crown to protect the molar is also usually placed during this visit.

First Visit: Investigation, Tooth Reshaping, Impression and Temporary Crown

During the commencement dental visit, an Ten-ray is commonly taken of the tooth and jawbone to investigate for signs of decay and other factors that could increase the take a chance of infection or injury to the pulp of the tooth. For some patients, root canal handling may exist required prior to the placement of a crown on a tooth.

The tooth volition demand to exist shaped to allow room for the crown to be placed; the extent of reshaping volition depend on the type of crown being used. Metal-based crowns tend to exist thinner and, therefore, require the removal of less structure of the tooth than porcelain crowns. The top and sides of the tooth are filed downwardly to shape the tooth as needed for the crown. Whatever tooth decay should too be treated during this step.

What is a perfect Dental Crown

For some patients with astringent decay or damage to the tooth, there may be insufficient tooth structure remaining to place the tooth. In this case, a filling fabric may be needed to build up the structure of the tooth so that the crown can later exist put in place.

Once the tooth has been adequately shaped, the adjacent step is to create an impression of the shaped tooth so that the crown can be fabricated to fit the molar as closely equally possible. An impression as well frequently needs to be created for the tooth on the opposing jaw that will connect with the crown when the patient bites. This is to ensure that the crown fits well to the other side of the mouth, in addition to the surface area where information technology will sit.

Impressions are unremarkably fabricated using a paste or putty that holds the shape of the molar. It is spread over the area to exist copied and and so pulled away, keeping the shape of the relevant teeth on its surface.

At this point, it is important to tape details virtually the tooth that will bear upon the product of the crown, such as the natural fit and color. Ideally, the colour of the crown should match that of the tooth and surrounding teeth so that it is non noticed when information technology is placed inside the mouth.

Finally, a temporary crown is usually placed over the tooth to protect information technology until the crown has been constructed and is set up to be stock-still in place. This volition be removed at the adjacent dental visit to make room for the permanent crown.

Second Visit: Permanent Crown Placement

In the meantime, the impressions of the teeth are sent to a dental technician or laboratory to form the crown in the right shape. This process typically takes up to three weeks, which is why more than one dental visit is needed to identify a permanent crown correctly.

Once the dental technician or laboratory has created the crown, it is time for the crown to be placed over the tooth. If a temporary crown has been placed, this should first be removed.

It is of import to check that the crown has been made correctly, ensuring that both the fit and the color of the crown lucifer that of the natural and surrounding teeth before it is cemented in.

A local anesthetic is commonly administered to numb the expanse during the procedure to fit the crown. Dental cement is utilized to set up the crown in place over the tooth. It may be necessary to make pocket-sized adjustments to the shape of the crown, particularly if there are problems with the patient'due south bite when the crown meets the opposite tooth.

Same-Day Crowns Placement Procedure

In some cases, crowns may be synthetic in the dental practice then that the crown can exist made and placed on the same 24-hour interval, without the need to send the impressions to a dental laboratory.

Rather than making an impression of the molar, a scanning device called a wand is used to take pictures of the teeth. These images are uploaded into computer software that creates a 3D model of the molar. This digital model can so be used to create a ceramic crown the same solar day. This method is known as computer-aided blueprint and manufacture of dental crowns (CAD/CAM) and can be completed in approximately 15 minutes so that the crown can apace be put in place.
