Over the years, dentists have tried a variety of methods to replace missing Teeth. They used both removable and fixed dentures. The latter one also has many different types, ranging from bar-retained dentures, through classic bridges, to implant supported dentures. The last one is deemed to be the most modern procedure.

By reading this article, you can become familiar with the following topics:

• Bar retained dentures
• Dental bridges
• Zirconium is the material of the future
• Fixed implant supported dentures
• Complete fixed dentures

Fixed dentures have many benefits compared to the removable types. They are more stable, firm in their place. For this reason they make chewing and speaking more secure. This results in a better mood and quality of life for the one who has such teeth.

Bar retained dentures

In this case, which involves the usage of clips, dentists fix partial dentures. Partial dentures become necessary if some teeth are missing from the dental arch, thus a minor gap needs to be bridged. Such partial dentures have many benefits. On the one hand, they restore the ability to chew. On the other hand, they prevent the remaining teeth from moving towards the those parts of the jawbone where there is no tooth left. Furthermore, they improve the facial aesthetics of patients, especially in the case of the front teeth.

When this kind of solution is implemented, the false teeth are placed on a metal bar, the two edge of which ends in clips. The clips are fixed on the remaining teeth. It’s advantage is that it is firmly fixed in the mouth, keeping the false teeth tightly in their place. It’s disadvantage is that the clips may be seen, which does not provide a really aesthetic sight. Another disadvantage is that the clips put a strain on and erode the unhurt teeth they are connected with.

Dental bridges

Dental bridges are modern and widespread tools for making fixed dentures. They have many different types, ranging from bridges that use porcelain fused to metal crowns, through pressed ceramic bridges, to zirconia bridges.

When using this method, the specialist grinds the unhurt teeth on each side of the gap. This happens to an extent necessary to fix the bridges safely on the teeth. Each of the two units on the ends of the structure functioning as a bridge over the missing teeth is a crown, and these crowns are fitted on the ground tooth abutments. The false teeth, which serve as a replacement for the missing teeth , are fixed between the tooth abutments.

This method is perfect for bridging larger gaps by replacing more than one missing tooth at once. Its disadvantage is that the tooth abutments need to be ground. A greater or smaller part from the material of entire unhurt teeth needs to be removed for the procedure.

Metal bridge frameworks or extremely hard zirconia bridges are recommended for bridging greater distances. The pressed ceramic (solely porcelain) bridges containing no metal are not suitable for such purposes, as they cannot withstand the bending force present.

There is also an intermediate solution for replacing two teeth at most. In this case the unhurt teeth holding the bridge are not ground, but a tiny niche is made in their surface. The two outer formulas at the ends of the bridge are fixed into these niches as dental inlays .

Zirconium is the material of the future

Special mention should also be made of bridges made from zirconium dioxide, as these are more and more prevalent products of modern dentistry. Zirconium dioxide is really strong material, even more solid than metal. It can especially withstand bending forces, which makes it absolutely suitable for bridging longer interdental distances. Due to the fact that it does not contain any metal or allergen, it can be used on anyone safely.

In addition, its aesthetic properties are significant. Its transparency is very similar to that of the natural dentition. For this reason, bridges (teeth) made from this material are confusingly similar to the natural dental arches. Its additional benefit is that it lets X-rays
through. Thus, on the part of the tooth abutments, which is under the bridge, any problem can be recognized at a really early stage without removing the bridge.

Fixed implant supported dentures

Nowadays, the production of implant supported dentures is deemed to be the most modern procedure. A great advantage of the technique is that it spares the unhurt teeth. The structure forming a bridge over the absence of teeth (the bridge) sits on the jawbone’s implants instead of ground teeth. Just two well ossified false roots are enough to provide adequate stability to bridges of normal length.

If many or all of the teeth are missing, dentists use more than one implants to fix the bridges. This way, even entire lower or upper dental arches can be replaced in the long run.

The slight disadvantage of this method is that it takes a long a time. It could as well be a matter of weeks when a patient gets a fixed denture, if the traditional way (the grinding of tooth abutments) is chosen. The fixed implant supported denture can be placed after about half a year. This is the amount of time necessary for the supporting false root to heal and ossify. The patient has to bear a minor dental surgical procedure as well. The long term advantages, however, amply compensate the patient for the inconveniences.

Complete fixed dentures

Implants may also grant a better quality of life to those who have removable complete dentures. In the completely edentulous mouth, the adhesive forces, the muscle tone, and the force of gravity hold the denture in its place. Even when combined, these forces cannot provide enough support for the process of chewing and speaking. However, two lower and four upper implants can provide great stability to the removable dentures. Chewing and speaking becomes more firm, the confidence of the individual is increased.

Those patients who are able to receive implants may also consider a replacement. This means that by having a bit more implants their complete removable dentures could be replaced with more convenient solutions of fixed bridges.
