Artificial dentition - Crowns and bridges restore your teeth
Artificial dentition means all measures taken for the restoration of a damaged or incomplete dentition. There are a lot of possible reasons for missing teeth, usually they had to be extracted due to excessive decay or gum disease. However, also accidents or missing dental development can cause the need for artificial dentition. Artificial dentition is necessary to restore effective mastication and to prevent possible subsequent damage. A missing tooth might, for example, lead to tilting or migration of teeth, bone recession or jaw joint conditions. Aesthetics, too, play an important role, missing front teeth or sunken cheeks in particular can influence the facial expression negatively. The main prosthetic options are tooth crowns and tooth bridges. Read more about them in the following paragraphs.
Restoration of one or more teeth
A crown becomes necessary when a tooth is so heavily destroyed that it cannot be treated with a filling or inlay, but is still worth being preserved. Crowns increase stability and form a protective cap around the tooth. They can also be applied in making unappealing teeth look better.
Before a tooth can be covered with an artificial crown it has to be ground into shape under a local anesthesia. After the so-called tooth preparation the crown is prepared in the laboratory. The tooth stump has to be protected by a plastic provisional until the crown is done. When the completed crown arrives from the laboratory it is fastened onto the tooth stump with special dental cement.
Materials for artificial dentition
A crown can be made of various materials. Most orthodontists apply metal crowns with a tooth-colored ceramic shell. We use the new and aesthetically more appealing form of artificial dentition:
the all-ceramic crown. The substructure is made of stable zirkonium oxide ceramics, onto which the veneer ceramic is fused. A completely metal-free crown made of biocompatible white ceramic. It is hardly distinguishable from natural teeth and therefore can even be used in the aesthetically critical front teeth area.

Tooth bridges - Closing spaces
A bridge is a piece of artificial dentition carried by the neighboring teeth. It is a means of closing spaces caused by missing teeth. It can bridge one or several missing teeth. If the neighboring teeth are intact and fulfil the stability requirements they has to be ground into shape for the bridge. The procedure of creating a bridge is similar to the procedure of crowns. The difference lies in the additionally required middle-piece which in shape and function is a full substitute for the missing tooth. All materials which can be used for shaping a crown are also suitable for bridges, i.e. the all-ceramics design (see above) we usually use for crowns can be applied here as well.
The options for fastening the bridge depend on the teeth that are available as bridge pillars. If there is more than one gap, the structural health of the remaining teeth and the position of the gaps decide if a bridge construction is possible. For example increasing the number of pillar teeth through tooth implants might become necessary. This situation might especially occur when the last teeth of the row are missing, the so called free-end situation. A healthy periodontal apparatus, i.e. jaw bones and gums, is a prerequisite and, if necessary, has to be achieved by respective treatment first.
Dental bridges replace one or more missing teeth by attaching them to the neighbouring teeth.

Crowns and bridges made from Pressable Ceramics
Using the latest computer technology, we produce inlays, crowns and bridges made from ceramic, completely abandoning the use of metal. The material used is named "Zirconia".
How does this work?
After preparing the tooth and removing its cavity we will take an impression that will be measured by a digital 3D scanner. Using this data, the computer program CAD/CAM is able to design your dentures. A computer-controlled milling machine will then cut out the exact form from a ceramic block - this procedure will we done at Dr. Hager's own laboratory. By adding another layer of special ceramics our dental technicians will adjust the color and shape for a perfect finish that matches your set of teeth exactly.

What makes this treatment so valuable?
These kinds of crowns and bridges are suitable for people suffering from allergies. Not containing metals, they are also easy to handle for your organism. A natural tooth is translucent. Tooth replacements that include metallic components are not fully translucent, making them look less lifelike. By using the new Zirconia Ceramics, this negative effect is avoided as it lets light come through. Another material advantage is given by the white color, so you no longer have the problem with dark metal edges that could appear from time to time. As you can see, this ceramic material is an ideal possibility for aesthetical front teeth. It also offers beautiful and natural results in the lateral tooth area.
