PST, the essential surgical template.

The anticipated prosthesis now dictates the placement and angulation of the implant, thereby improving the function and the aesthetics of the final result. To establish a logical continuity between the surgical phases and the planned prosthesis, it is essential to use a transfer device. The restorative clinician can request a precise position and orientation of each implant with this communication tool. However, it is difficult to use a conventional surgical template following the soft tissue reflection and during preparation of implant osteotomy. The proper positioning of each implant is difficult to achieve, especially on a completely edentulous maxilla where restorations require even more ideal implant placement.
