7.4 Optimising during dynamic trial fitting
► During the dynamic trial fitting, test and optimise the prosthesis with its
various distal prosthetic components.
CAUTION! If the settings of the prosthesis with its various distal pros­
thetic components exhibit opposing effects, the safety-related aspects
always have to take precedence over everything else in choosing a com­
promise setting.
7.5 Attaching the cosmetic cover
► Fabricate the cosmetic cover so that the quick-change function can be
operated reliably.
7.6 Finishing the prosthesis
► To finish the prosthesis, all screw connections have to be tightened
according to the prescribed specifications with regard to Nm and the
use of thread lock, and the correct functioning of the prosthesis has to
be tested with its various distal prosthetic components.
