Transfers
In dental surgery, the metal prosthetic components used at the stage of impression taking are referred to as the impression transfers. They are meant for:
• secure retention of implants (their analogues) and abutments in the cast model;
• more precise and individual treatment of construction of the dental prostheses in laboratory conditions.
It is possible to take an impression with the installation of a transfer only from the implant or abutment. In the Dental Prosthetics Technology, it is important that a transfer would remain in the extracted cast model after taking an impression. However, the variants when a transfer is put in the finished cast model after taking an impression are possible.
The transfers are as a rule manufactured of cheaper stainless steel. According to their construction, the transfers may be as follows:
• for impression taking by the method of open impression tray;
• for impression taking by the method of closed impression tray.
In the form of securing:
• with securing by screw;
• with clipping securing
