Over-Denture (Telescopic denture / Precision chrome denture / German Denture)

The telescopic denture is an affordable alternative at half the cost to implant dentures or All-on-4 and they can be made much faster than any other treatment.

This system require that we have enough teeth in the mouth or we have enough bone to place implants to be able to place a denture with telescopic denture technique over the crown, over natural teeth or dental implants. Telescopic denture is removable and allows for ease of cleaning and repair if required.

How do telescopic dentures work?

The dentures are held in place using telescopic crowns on your own teeth or your implants without seeing or using any hooks being connected to the denture. They were invented in Germany by Professor Koerber in 1968 as a German precision partial denture (without clips). In most cases, telescopic dentures don’t affect your speech.

How are telescopic dentures fitted?

The remaining teeth are prepared with a drill so that a ‘crown can be fitted over the tooth. This crown is in the shape of a cone with a 5° taper, and not the normal bell shape of a natural tooth. This crown is technically called a primary crown and it is permanently cemented over the prepared tooth.

One telescopic crown or an inner cap is cemented permanently onto your tooth or abutment of the implant (in these situation abutment are made as inure crown over implants), the other outer cap on top looks like your teeth and combines with your denture. If you can imagine two cups representing the two crowns being stuck together, when you pull them apart you feel resistance.  The telescopic denture is held in place with friction technology.

If a sufficient number of secondary crowns (at least 6 ) are incorporated into the body of the denture there is no need to cover the palate (roof of the mouth).

The procedure

  •  Preparation of the teeth and taking impression of the teeth and implant if there is any implant for telescopic denture
  • Primary telescopic crowns made and cemented over teeth and implant.
  • Telescopic denture inserted and sliding onto primary telescopic crowns

How many teeth are needed to support Telescopic Dentures?

Telescopic Dentures can be fitted to a few remaining teeth but need the support of a minimum of two teeth per jaw. Ideally, one on each side, usually only  between 2-6 teeth are required. The denture may also extend to 6 -8 teeth. It depends on the condition of your teeth. If you lose teeth later or years down the track, teeth can be added to the dentures, so there is no need for new dentures to be remade.

If you have only dental implants, the abutment over implant can be made as cone crown, the  telescopic dentures can be attached to those implants. Telescopic Dentures classically fit to cone crowns on natural teeth but can also fit to abutments on implant fixtures. See the case below

This case is a combination of patient’s their own remaining two teeth in lower jaw and two implants with telescopic crown.

 

What are telescopic dentures made from?

This is a really affordable alternative at half the cost to implant dentures or All-on-4. Even better, they can be made in a few weeks.

This fixed but removable telescopic denture allows for ease of cleaning and simplicity of denture repair if required. This video below will give you a better understanding of how this denture technology works. Because the plate itself is made from Chrome Cobalt, which is a high bio-compatible material, it’s accepted by the body and not rejected. This has been used in dentistry and medicine for many decades. In telescopic dentures it’s been used since 1982 and it’s a good strong material. The actual teeth are made out of composite, so the colour can be made to suit or match any desired colour.

The cone crown is made from a variety of materials including cast stainless steel and zirconium. A secondary crown made of the same material is designed to frictionally fit intimately over the cone crown and is incorporated into the telescopic denture.
