Dental prostheses can first be divided into partial and full dentures:
Partial dentures replace part of healthy teeth, for example after extensive tooth loss in the cheek area. The still existing natural teeth remain visible and the dentist uses them (partially) to fix the partial denture.
Full dentures (also known as full dentures) are used when the entire dentition in the upper or lower jaw has to be replaced. This is especially the case when there are no more teeth at all or when the teeth that are still present are covered with the attachment as is the case with the telescopic prosthesis.
In case of large gaps or missing teeth in the lateral area of the jaw, a so called free end situation, the standard dental care is a partial denture. This kind of denture is normally attached to the remaining teeth by clasps, has an uncomfortable palatal or lingual bar and not a really stabile retention, resulting in movements of the denture while eating or speaking and food impaction under it.
In case of total tooth loss (edentia) the only solution is a full denture. In the upper jaw the full denture is only attached by suction; therefore the denture must cover the whole palate, which may lead to gag reflex and dysgeusia (loss of taste).
In the lower jaw a full denture has always a U shape because of the tongue; therefore there is almost no suction function, which leads to an even worse retention
An ideal solution is our speciality, the Telescopic Denture. It can be attached to even a few remaining teeth or – in case of edentia – to implants.
The first step is the production of the primary crowns in a parallel milling machine, so that they are all parallel to each other. The second step is the production of the secondary crowns, which are connected with the denture and fit precisely on the primary crowns resulting in an extreme strong retention.
After the primary crowns have been glued on the remaining teeth, the telescopic denture can be inserted. The secondary crowns slide on the primary crowns with high precision; when the denture is completely inserted, no metal can be seen.
In most cases the telescopic denture can be produced without any annoying palatal or lingual bar, has a significant better retention as any partial or full denture and is therefore almost indistinguishable from natural teeth.
The telescopic denture is very easy to maintain: In case of tooth loss the denture can be easily adapted without the necessity to produce a new denture, as it might happen with other types of dentures.
Besides any necessary repair works will take place outside the mouth. As already mentioned in case of edentia a telescopic denture can also be inserted on implants.
Bar prostheses are a variant of the partial denture. Strictly speaking, they count as combined dentures because the removable dentures rest on firmly anchored support elements, the so-called bars.
The bars are attached to implants and remain permanently in the mouth. The partial prosthesis has a so-called bar rider on the underside, which snaps into the bar like a hinge.
The bar construction offers a firm hold and enables a comparatively graceful prosthesis construction with high wearing comfort.
The artificial teeth can be removed and cleaned, cleaning the bar itself is a little more complicated. It is therefore recommended that the prosthesis wearer be instructed by a prophylaxis expert.
Model cast denture
This removable dentures is used by the dentist when many teeth are missing and implants are out of the question.
It is made of plastic and metal. The teeth are in a pink plastic base that is attached to the patient's remaining teeth using metal clips. Many patients do not like these brackets because they are very noticeable. Compared to the much more aesthetic telescopic prosthesis, which is an alternative, the staple prosthesis is a cheaper denture. Therefore, it is still chosen by many patients.
Auch bei der Geschiebeprothese handelt es sich um eine Form des kombinierten Zahnersatzes. Der herausnehmbare Teil besteht, wie bei allen bisherigen Varianten der Teilprothese, aus einer Kunststoffbasis, auf der die künstlichen Zähne ruhen.
Als fest verankerte Stützelemente dienen auch hier entweder über Grunde natürliche Zähne oder Implantate. Die künstliche Krone verfügt dabei über eine spezielle Konstruktion aus Matrize und Patrize, die perfekt ineinanderpassen.
Dies bietet eine gute Ästhetik, hohen Tragekomfort und guten Halt beim Sprechen und Essen, erfordert jedoch eine stabile Restbezahnung – wenn ein Stützzahn verloren geht, muss die gesamte Prothese erneuert werden. Nachteilig ist der vergleichsweise hohe Preis aufgrund der technischen Komplexität.
Fixing a denture to implants using locators is one of the most convenient and safest ways to securely anchor the denture. This is an optimal alternative to the classic full denture (with a palate plate in the upper jaw).
For this purpose, four implants are usually inserted into the tooth-free jaw and a narrow, safe and comfortable prosthesis is attached with a kind of push-button system, the so-called locator.
Full dentures, popularly known as "dentures", are still the standard for restoring toothless jaws with dentures. The saying "teeth are like stars: come out at night" alludes to the often not very high level of comfort of these simple prostheses, which makes wearing them difficult. But there are many full dentures ("total") that shine with an extremely satisfactory fit, impeccable function and excellent aesthetics. A denture in the upper jaw, in particular, is very satisfactory for patients under favorable conditions.
