With soldered retentions on the attachments, the Herbst® appliance can be integrated into splints and therefore be removable
The working casts are mounted onto the fixator with the construction bite. The vacuum formed foils are made out of 1 mm material and are finished like normal splints. Retentions are soldered onto the attachments and then heated to be pressed into the splints for their fixation.
The length of the guiding hinges has to be checked and if necessary, modified.
Now the splints can be built up with acrylic in the molar area for the definitive fixation and stabilization. In order to achieve corresponding planes in the upper and lower jaw, first, the lower splint is finished, polished and isolated; afterwards, the upper jaw is built up with acrylic and set together in the fixator. Then only the exceeding acrylic material has to be removed.
