Modeling
Fabrication­of­a­resin­coping
To prepare the wax-up, a resin coping is prepared if both hybrid abutments and hybrid abutment crowns
are fabricated. Please observe the following procedure:
– Check the implant position and inclination with regard to the position of the screw channel.
– Screw the Ti base onto the model analog with the corresponding screw.
– Tip: Make sure that an additional model analog is available as this will facilitate some steps.
– Clean the Ti base with a steam cleaner.
– Insert a pin with the same diameter as the screw channel to "seal" and "extend" the screw channel.
– Do not apply die spacer.
– Isolate the Ti base and the pin with a thin application of separator. If too much separator is used, this
might result in uneven areas on the inner aspect of the pressed object.
– In order to achieve a sound fit and to facilitate the subsequent wax-up, a coping is first fabricated on
the Ti base with modelling resin. Design the coping in such a way that it can subsequently be com-
pletely covered with modelling wax. Please observe the instructions of the manufacturer regarding the
processing of modelling resin.
– Remove the Ti base from the model.
– Eliminate possible over-contoured areas of the resin coping at the transition area to the Ti base by
means of rubber polishers. Do not damage the Ti base.
– Remove the resin coping together with the pin from the Ti base.
– Loosen and remove the pin by rotating the resin coping.
– Screw the Ti base onto the model analog again.
– Place the resin coping back on the Ti base and check the fit and dimension (e.g. silicone key). If
necessary, adjust the coping by means of rotary instruments.
