Anterior crowns

Anterior tooth metal ceramic crown



Anterior crown procedure

The purpose of a crown is to protect a damaged tooth by a complete sheathing. This sheath can be made of metal, ceramic or plastic. This protection is intended to preserve the remaining natural tooth for as long as possible.

There are various possibilities when selecting the material.

Although metal alloys are among the most stable and durable solutions, they are out of the question in the anterior region for aesthetic reasons.

In the anterior region, ceramic is often used, which is connected to a metal shell. This combination is robust yet aesthetically pleasing. This metal-ceramic crown is now generally regarded as the standard solution.

Ceramic mass is burned on a special metal alloy. A special variant of the metal-ceramic crown, the so-called galvanocron, instead of a cast metal alloy, uses a galvanized fine gold layer, on which the ceramic is applied. Since the metal core is veneered with the ceramic, one also speaks of a veneering crown.

Although the metal core gives the crown a high stability, it is less transparent than an all-ceramic crown. Especially in the area of the front teeth, the metal-ceramic crown can therefore optically differ from the natural neighboring teeth.
The disadvantages of the metal-ceramic crown: The edges tend to have a darker color and the cosmetic result is not as perfect  as with an all-ceramic crown.

The all-ceramic crown or jacket crown is probably the most perfect solution from an aesthetic point of view. Here, the tooth is coated exclusively with ceramic and the natural tooth color can be imitated particularly well. The translucency, i.e. the light transmission, can also be designed here with the natural tooth and a metal framework is completely dispensed with. In order to achieve a high level of stability, there are various processes based on the first production of a high-strength, ceramic cap, on which the tooth shape and colour can then be designed with other ceramics.
A crown can be used in the following cases:
  • Replacement of a filling if there is no longer enough tooth substance to attach the filling.
  • Protecting a weak tooth from breaking
  • Restoration of a crack in the tooth structure
  • Attaching a bridge
  • Covering a dental implant
  • Covering of a severely discolored or malformed tooth
  • Covering a tooth that has undergone root canal treatment.

A crown can also be the basis for a bridge. This is referred to as an anchor or abutment tooth.

Treatment steps

In order to provide a tooth with a crown, the tooth must be prepared, i.e. part of the hard substance must be removed.

Then an impression is made of the tooth stump. Which serves the dental technician as a template for the production of the crown. In the dental laboratory, this requires a number of many different work steps. Until the final completion of the crown, the tooth stump can be supplied with a so-called provisional (usually made of plastic). The temporary prosthesis has the task of keeping stimuli such as heat and cold away from the tooth stump and keeping the ground tooth in its position.

Use of dental floss


With a toothbrush you can only reach about 70% of the tooth surface. The space between the teeth (interdental space) cannot be completely grasped by it. For an optimal result of oral hygiene, the interdental spaces should therefore also be cleaned with dental floss. This removes plaque and food particles between the teeth and thus prevents caries between the teeth and gum disease.

Procedure: The dental floss is looped C-shaped around the tooth. With upward and downward movements, the tooth is carefully cleaned. This dental care is best done twice a day. The best time is just after eating and before bed. Thus, bacteria hardly have a chance to spread.

The super floss or superfloss dental floss is particularly suitable for cleaning braces, implants and bridges. It has a reinforced beginning at the threading aid, as well as a fluffy middle area and is therefore optimal for the needs of orthodontic patients.

Super Floss

Cleaning bridges

Caries no longer causes damage to porcelain or metal, but this does not mean that you no longer have to clean a ceramic or metal bridge. Quite the opposite. Each bridge has a weak point, namely the transition point between the bridge pier or .dem natural tooth and the gums. This area needs to be cleaned extra carefully. Food debris can also get caught under the bridge. These quickly form plaque that trigger bad breath and irritate the gums. Therefore, maintaining proper oral hygiene is a crucial factor for the lifetime of a bridge.

For proper cleaning of your bridge, in addition to the usual cleaning measures with toothbrush and toothpaste, additional cleaning with an interdental brush and dental floss is recommended. The slightly thicker so-called superfloss floss is best suited here. With this you can also get to hard-to-reach areas and can also clean the gap between the bridge pier and artificial tooth very well.

Gently insert the brush from the cheek or tongue side into the space between the crown and bridge member and move the brush back and forth several times. You can also do this with the superfloss floss by carefully threading the floss through the gap and moving it slightly back and forth.
If you are unsure, let us show you the correct cleaning again. Preferably with professional tooth cleaning, which you should have done once or twice a year.

Bridges

Bridges are used when one or more missing teeth need to be replaced.
From a medical point of view, the gap caused by the missing teeth should be closed as soon as possible. Otherwise, it can lead to bone loss as well as tooth and jaw misalignments. The opposite tooth can also be affected because it no longer has a counterpart when chewing.
As with the crowns, there are also different materials to choose from for bridges. Ceramic bridges can best be adapted to the natural tooth color. In a personal conversation, we can advise you on which material is most suitable due to the location of the missing tooth (or teeth), its function, aesthetic considerations and, last but not least, the cost.


 
Bridge by means of crowns

Bridges by means of crowns

In a bridge that is fastened with crowns, the adjacent teeth are ground all around to serve as abutment teeth for the bridge. This means that the adjacent teeth are crowned and the dentures for the gap are attached to the crowns. The disadvantage is that otherwise healthy teeth have to be ground in this procedure to attach the crowns. The advantage of this solution is the relatively lower cost.


 
Bridge by means of inlays



Bridges by means of inlays

In an inlay bridge, unlike conventional bridges, the adjacent teeth are not completely ground, but here the inlays, i.e. the fillings of the neighboring teeth, provide the necessary support. The advantage here is that less tooth substance has to be sacrificed. However, this technique is only used on the posterior teeth, as there must be enough substance to support the bridge stably .

Digital color determination

Determining tooth shade remains a major challenge for both dental technicians and dentists. It has been done visually for decades by comparing the tooth colors in the mouth with special color samples.

This step in the context of color adaptation is thus based on human perception, which, however, is subject to numerous variable influences. Consequently, there is an inaccuracy in the visual color determination, which depends on personal perception.

The digital measuring device provides a remedy here. With it, color, brightness and chroma are recorded on the tooth over the entire surface, including the adjacent teeth. This is the main advantage compared to visual color determination. The tooth shades can be determined precisely without fluctuations influenced by ambient light and natural light. In addition, it is possible to check the color result during the production process of a dental restoration. Digital color determination is therefore a valuable instrument for quality assurance.
