Victoria Street Dental Offer CADCAM Technology For Crowns

A dental crown or bridge is a tooth-shaped cover that is placed over an existing tooth. It is done so to protect and strengthen a structurally weakened tooth from further deterioration. They are usually fabricated outside of the mouth in a dental laboratory so often will require at least two appointments. However, you can also take advantage of Victoria Street Dental’s CADCAM technology to create a crown.

CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM (computer-aided design and computer-aided manufacturing) to improve the design and creation of dental restorations, especially dental crowns.

There are several reasons as to why you may require a crown, including replacing a large filling when there isn’t enough tooth remaining, protecting a weak tooth from fracturing and restoring a fractured tooth. After careful examination and discussion between yourself and the dentist, a decision is made on whether to get a crown or a filling.

Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size to create space for the crown or bridge to fit over top. The dentist will take an impression of the reduced tooth to provide the dental laboratory with an exact mould of your teeth. After decayed or broken areas of the tooth are corrected by the dentist, an image (scan) is taken of the prepared tooth and the surrounding teeth.

This image, called a digital impression, draws the data into a computer. Proprietary software then creates a replacement part for the missing areas of the tooth, creating a virtual restoration. This is called reverse engineering. The software sends this virtual data to a milling machine where the replacement part is carved out of a solid block of ceramic or composite resin. Stains and glazes are fired to the surfaces of the milled ceramic crown or bridge to correct the otherwise monochromatic appearance of the restoration. The restoration is then adjusted in the patient’s mouth and cemented or bonded in place.

The most important step you can take to ensure the longevity of your crown is to practice good oral hygiene. By brushing and flossing around it like a normal tooth it prevents unwanted gum disease or decay, so for more information on dentists Wellington, dentists near me and dental crowns please go to http://www.victoriastreetdental.co.nz .
