Telescopic dentures are held in place using telescopic crowns on the natural tooth or implants without any hooks. One telescopic crown or an inner cap is cemented permanently onto 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 tooth and combines with the denture. If imagining two cups representing the two crowns being stuck together, when pulling them apart one feel resistance. The telescopic denture is held in place with friction technology.
Long term benefits of a telescopic overdenture are:
1) Increased mouth function due to precision fit over natural teeth
2) Improved aesthetics with no clasps
3) Prevention of bone loss
4) Future tooth losses do not affect a telescopic denture
