Porcelain Bridgework – If you’ve lost teeth due to accident, injury, or gum disease, we may recommend a permanent bridge. A bridge not only fills the gap created by a lost tooth, but it also prevents movement of remaining teeth.
Dental crowns can be made from porcelain, gold, or a combination of the two materials. They completely cover a filled or broken down tooth as well as providing strength and support for teeth which have been heavily filled, fractured or root treated. Many patients ask how long crowns last and this largely depends on how well teeth are looked after. However we would expect a good quality crown to last for between ten and fifteen years.
Bridges can be used to replace one or more missing teeth. Minimally destructive adhesive techniques can sometimes replace a single tooth by bonding to healthy adjacent teeth. Conventional fixed bridgework can be constructed to replace one or more missing teeth by using fixed crowns on the adjacent teeth, supporting the replacement in between them.
All our laboratory made restorations are constructed to the highest standard in conjunction with highly skilled technicians with whom we work very closely. When necessary we will arrange for you to meet our ceramist in the surgery so that the shade for your restoration can be photographed allowing the best possible colour match.
Materials For Crown and Bridgework
Porcelain-Fused-to-Metal. Porcelain is the most esthetic material ever devised for Dentistry. When it is fused to metal, the color of the metal must be masked with an opaque porcelain. Porcelain cannot be baked on pure gold because gold melts at the temperature required to fuse porcelain. There are many different alloys available for porcelain-to-metal restorations. The precious metal alloys, which contain varying amounts of gold, silver, palladium, platinum and other noble metals, are all suitable for porcelain-fused-to-metal restorations. Nonprecious metals, however, are not. They do not cast with the same accuracy and the porcelain fused to it has a higher incidence of breakage.
All-Ceramic or “Metal-Free” restorations are the most esthetic restorations in dentistry, since they can be designed as translucent as natural teeth. These restorations can be baked, pressed or milled. However, all ceramic restorations do not fit with comparable accuracy to metal restorations. Because ceramic restorations cannot have thin aprons that extend under the gum, they cannot seal the teeth as effectively. They depend on bonding materials to seal the voids—materials that can be inconsistent because they are so technique sensitive. These inconsistencies often lead to decay in a susceptible individual. Ceramic restorations work best in the front of the mouth where they are easily accessible for hygiene.
Reasons for a fixed bridge:
Fill the space left by missing teeth
Maintain a full facial shape
Prevent remaining teeth from drifting out of position
Restore chewing and speaking ability
Restore your smile
Upgrade from a removable partial denture to a permanent dental appliance
Our Dental Crown Procedure
Dental Crown treatment is arranged in the following steps according to the results of the consultation:
• Preparation of the teeth
• Taking the impression
• Insertion of the Temporary Crown
• Construction of the Crown
• Insertion of the final Crown
During your first visit the dentist will prepare the teeth to provide an easy fit for the crowns.
An impression of your teeth is taken which is used to construct your crown.
A temporary crown is then fitted onto the teeth.
On your next visit the dentist removes the temporary crown and fits the permanent crown onto the teeth.
