Ideal, axial load by the prosthetic construction was often impossible because of unfavourable localisation of the implants.

The data of 73 patients (76%) were evaluated. While the clinical periimplant findings were comparable, the majority of these patients were satisfied with this form of oral rehabilitation.

All familiar mechanical-manual and electronically supported methods as well as computer methods of some electronical recording systems have their limitations and are partly incorrect up to now. The reason for this lies mainly in the theoretical respectively mathematical approach towards these methods. With the aim of determining a point of minimal translatory movement (\"steady point\") during the rotatory opening movement in the TMJ condyle, a mathematical method is presented, which calculates the 3D coordinates of the condylar rotation centers automatically, i.e. without manual manipulation of the recording system.
