Prosthesis on telescopic crowns
Every patient coming to the dentist wants to get comfortable and durable prosthesis, especially when it comes to portable designs. To date, of all the interlocking telescopic dentures are probably the most reliable. Telescopic prosthesis consists of two parts. The first part, the primary crown is fixed on the tooth. The second part is itself prosthesis in which the secondary crown.
To remove the prosthesis on telescopic crowns do not have to open a different gate (latches) and push buttons. He simply removed, and also just getting dressed. Teeth are covered by telescopic crowns do not have a functional overload, as the load on the tooth is strictly along the axis of the tooth. Therefore, even highly mobile teeth can be used as a support for the telescopic dentures. In the case of the loss of a telescopic denture abutment teeth do not have to redo it. All locking prosthesis in this case is not repairable and will need to rework the whole structure.
Telescopic prostheses retained on the teeth using double (telescopic) crowns. One part is a metal cap with parallel walls, fixed on the tooth. Another part of it may be a bridge or a removable clasp protetezy.
At a fixed prosthesis secondary part exactly sits on its primary crown and by the force of friction (metal to metal) prosthesis is held in the mouth.
The more teeth covered by telescopic crowns, the stronger the fixation of the prosthesis in the mouth.
During the operation (about 3-4goda), due to friction, crowns and dentures are free to lose a little traction with his teeth. To improve the fixation of telescopic prostheses in Germany has developed a system FGP (Friktions-Geschiebe-Passung).
In a free telescopic crowns paid HRF. The prosthesis is fixed in the mouth, after 5 minutes remove the prosthesis. Due to the transition to a plastic-metal friction force adjustment is achieved by the force of adhesion to the denture teeth.
At the time of manufacture the prosthesis can be pre-lay design elements that will keep the denture in the mouth.
Galvanic cap-is located between the primary and the secondary part of the telescopic crown. When loosening of prosthesis fixation, he is given to the laboratory where using electroplating restore the cap.
To fix the use of magnetic alloys (magnets). Primary and vtorichnyekoronki attracted to each other. Very reliable, no need to change and add many years to come.
Using a sapphire ball in the secondary structure prosthesis. In the primary cap is a small indentation. At a fixed prosthesis sapphire ball falls into a pit on the primary crown and well-captures the prosthesis in the mouth. During the operation does not require any correction since the prosthesis does not lose adhesion forces to the teeth than ever before. The most popular type of fixed prosthesis.
