Transferring The Adapter Position; Vacuum Forming - Otto Bock Harmony P3 Technical Information

Procedure

3.8.1 Transferring the adapter position

Objective
The transfer device is used to transfer the adapter position from the check prosthesis to the definitive prosthesis.
The check socket is then filled with plaster and adapted to the plaster model.
Required tools and materials
• 743A160 transfer device, oscillating saw, tape measure, 716Y3 half-round file, 716Y4 round file, 649G22=180
grit cloth
