Telescopic crown: Safe anchoring for your prosthesis
Removable dentures often do not have a secure fit. Even if they are still so high, many patients have difficulty eating or talking. Here a telescopic crown or several telescopic crowns can be the solution: they anchor a hybrid prosthesis securely to the remaining teeth – and ensure a very good grip. Read all about dentures on telescopes and for whom he is suitable.
What exactly is a telescope crown?
- It is also called a double crown
- Consists of indoor and outdoor telescope
- For attachment of hybrid prostheses
In short, a telescopic crown is a double crown on a tooth that serves to anchor a partial denture. These prostheses are called hybrid or telescopic prostheses.
The double crown consists, as the name implies, of two crowns that can be inserted into each other. The inner part, which is attached to the own teeth by the dentist, is the primary crown, or the inner telescope. On the primary crown, the secondary crown, or even the outer telescope attached. The primary crown is not removable and does not look like an ordinary crown. It is not like a natural tooth, but rather a cone. Due to their smooth shape, the outer telescope can be placed precisely over it. The outer telescope looks like a real tooth and is integrated into the row of teeth of the telescopic prosthesis. Thus, the telescopic prosthesis is attached to the own teeth via the telescopic crown.
Which materials are used?
- Non-precious metal alloys
- gold alloys
- Galvanogold for inner telescopes
- Veneering of external ceramic telescopes
Telescopic crowns are made of metal, since the ceramics developed to date can not withstand the stresses during the cleaning and removal of the prosthesis. As metals non-precious metal alloys and gold alloys or the special production of galvanized gold come into question. Your dentist advises you in choosing the right material.
In order to be able to offer patients an esthetic denture, it is possible to veneer the external telescopes with ceramics. Thus, they do not stand out in color from the remaining replacement teeth in the hybrid prosthesis, which are made of tooth-colored plastic.
Which advantages and disadvantages are to be considered?
- good and stable hold, feels like stuck
- Protection of abutment teeth
- less bone loss
- good aesthetics
The biggest advantage of the telescope crown is the good and stable hold, which gives patients the feeling that they finally have firm teeth in their mouths and can bite them again. The comfort is very similar to fixed dentures. In addition, the teeth to which the prosthesis is attached, protected from improper loading. They are loaded evenly, unlike a conventional staple prosthesis. Even heavily damaged teeth, the dentist can thus include in the supply. A telescopic prosthesis also reduces bone loss, since the jawbone is less heavily loaded.
Another great advantage of telescopic prostheses and crowns is the aesthetic appearance, since no metal-colored brackets are used.
The disadvantages at a glance:
- Loss of hard tooth substance
- Decreased aesthetics with the prosthesis removed: metal tooth stumps visible
- higher cost
As disadvantages come into consideration that the dentist for the telescopic crowns must grind more hard tooth substance in order to create enough space for the crowns. Also, the aesthetics of the prosthesis is very good, however, when removed, metal stumps come to the fore, which can deter some patients.
Also significantly higher costs are a disadvantage: the treatment has its price and is not taken over by the health insurance companies.
Is the telescopic crown suitable for me??
In the upper jaw, the fit of prostheses is usually better, which is why patients, especially in the lower jaw, benefit from better grip. The dentures can be used when patients have lost multiple teeth and no bridge is possible, but they do not want to have a brace prosthesis. However, there must still be teeth in the mouth that are suitable for telescopic crowns.
