Missing several teeth can severely influence your daily life. It can affect your general health, your appearance and self-esteem. It can start affecting your appearance, your oral health and even your health in general, so it has many negative affects. Missing teeth disturb the interplay between teeth and bone. Because gum and bone are no longer stimulated well enough due to the missing tooth, the jaw bone starts shrinking and the gum pulls back. This may weaken neighbouring teeth until they collapse. Teeth in the opposite jaw can then start growing into the gap. Even speech disorder may occur. There are several ways in connection with dentures, depending on the type and place of missing tooth. Dental crowns are used if there is no missing tooth yet, but the tooth crown is damaged due to tooth decay, trauma, abrasion or erosion, that the problem can’t be solved by a dental filling. In case of more missing teeth, dental bridges literally bridge the gap. A bridge is made up of two or more crowns for the teeth on either side of the gap. Similar to crowns, bridges can be made from a variety of materials. The bridge is fixed on the abutment (adjacent) teeth, these give the necessary support. The disadvantage of this method is that the healthy abutment teeth on either side of the gap must be grind down. This can be avoided if the bridge is fixed on implants. Not only the teeth are saved from grinding, but the lack can be shortened, so a structurally reliable bridge can be prepared. If the missing teeth are at the end of the dental arch, the abutment tooth can be replaced by implants.
Porcelain-fused-to-metal dental crowns
The basis of this crown is a nickel-free, hypoallergenic metal frame, which is fused by porcelain. Porcelain-fused-to-metal dental crowns can be colour matched to your adjacent teeth. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. Thanks to great high-load bearing these type of crowns are extremely durable, their price is more favourable than in case of zirconium crowns, but they’re less aesthetic: even by choosing the most perfect cover layer, a fully natural replica of natural teeth can’t be achieved.
This bridge is comprised of a metal alloy framework and ceramic crowns which are designed as a replacement of missing teeth. This is a durable and resistant solution, the disadvantage is, that this may have an allergenic effect and it doesn’t have a natural look as in case of zirconium bridges. Therefore this solution is rather recommended for the back chewing area.
A dental implant is a titanium post (like a tooth root) that is surgically positioned into the jawbone beneath the gum line that allows your dentist to mount replacement teeth or a bridge into that area. Titan doesn’t corrode or irritate the surrounding tissue, it is biocompatible, therefore it inserts perfectly into the bone tissue. In case of the replacement of one tooth a crown can be placed, in case of more teeth inserted dental implants can be function as stable and reliable pillars for dental bridges or even a complete set of teeth / denture. The implant-supported dentures resemble the aesthetic of natural teeth the most, they are able to assume the role of the lost teeth and their capacity is the same.
Removable full denture
The conventional solution for the replacement of missing teeth are removable dentures. Their task is not only the replacement of the teeth, but of the gum as well. The denture is resting on the mucous membrane – ground bone, the fixation is ensured by facial muscles, surface of the mucous membrane, the vacuum effect, the chewing pressure and gravitation. The basic material is a special plastic, which is often combined with metal parts. If the plastic dries out, the actually form of the dentures might deform, therefore this must be always kept wet.
Purpose of full dentures:
- Restoration of chewing ability
- Correction of changed facial features
- Aesthetic restoration
- Prevention of damage to the jaw joint
- Prevention, restoration of speech disorder
- Preventions of the mental disorder caused by toothlessness
These ones are a combination of a fixed bridge and a removable prosthesis. In most cases this is the only applicable solution, if the patient hasn’t got enough remaining natural teeth, to prepare bridge dentures for the whole jaw and/or implants are inserted. Mostly cases are typical in which the patient still has incisors in the front, but a lot of molars are already missing. The preparation is relatively lengthy, it’s regarded as a complicated dental technician work, but this solution is compared to partial dentures more aesthetic and provides a more perfect solution.
Ceramic crowns are prepared for the remaining natural teeth, which are bonded fix, in which links – anchors, attachments – are worked into. With the aid of these links the removable prosthesis is connected with the residual set of teeth. One part of the press stud is at the end of the bridge, the other is fixed on the denture. If the denture is put in its place, the anchorage can’t be seen. Advantages of combined dentures are: stability, optimal charge of the teeth and thus no loosening of teeth. By the use if the hidden anchorage a very advantageous aesthetic effect can be achieved.
A meglévő fogakra híd készül, amelyre egy fémlemezre készített részleges fogsort kerül. Ezt a fogsort egy vagy két oldalon, függően az illeszkedési helytől, speciális, ún. csúsztató köti össze a híddal. Mivel a rögzített rész stabil, nem mozgatható, a kivehető részt (fogsor) stabilizálja, a helyén tartja. Ez a stabilitás alapvetően tehát a precíziós csúsztató(k)nak köszönhető, ami összefogja a két különböző fogpótlást, így biztosítva tökéletes harapást és külső megjelenést egyaránt.
As long as the final dental crown, bridge or dentures aren’t prepared or during the healing period after a tooth extraction, after implantation, it is possible to prepare provisional dentures. Provisional dentures help to reduce the sensibility of the prepared, grinded teeth, on the other hand if the dentures are placed at an easily visible place, it can preserve you smile.
In a case of urgency or for a short period, the provisional dentures can also be prepared and fixed at the dental practice until the placement of the final dental crowns or bridges (1-2 weeks). But if the dentures shall be placed instead of an extracted tooth, more durable provisional dentures must be prepared for the healing period (4-6 weeks) by a dental technician. Such dentures can also be used for the healing and osseointegration phase after dental implantation (3-6 months).
