An implant is generated which is functionally and aesthetically adapted to the patient with a greater degree of precision, irrespective of the size, form and complexity of the defect, whereby the implant can be produced and operatively inserted into the patient over a short time period and in a simple manner. A virtual three-dimensional model of the patient which is formed from existing recorded (two-dimensional) image data of the patient is compared with real medical reference data. The comparison which is, for example, carried out using a data bank with test person data enables a reference model object which is most suited to the patient or closest to the patient model to be selected or formed and a virtual implant model is generated accordingly. Computer numeric control data is directly generated from the implant model which is generated virtually in the computer for program-assisted production of the implant.

A generic model structure captures basic characteristics in BIS-based patients' responses to anesthesia and surgical stimulation, the model being used in combination with the insight of an anesthesiologist. The model structure represents the patient response with a time delay, a time constant for response speed, and a nonlinear function for drug sensitivity. Clinical data confirms the model structure and is used to establish parameters and function forms for individual patients. A feedback and predictive control strategy for anesthesia drug infusion is then introduced on the basis of the patient model. Feedback control alone cannot avoid large fluctuations in BIS values when significant surgical stimulation is imposed, as a result of time delays in a patient's response to drug infusion. Predictive control attenuates fluctuations of BIS levels from surgical stimulation.
