  • Full dentures are currently manufactured by a series of purely manual steps.
  • the dentist takes impressions of the edentulous mandible and maxilla, which is usually done using a face bow to achieve an exact spatial model assignment for later processing in the articulator.
  • the impressions are then sent to the dental technician and filled with a model mass, such as plaster, to produce appropriate models of the maxilla and mandible.
  • the dental technician uses the jaw models spatially assigned to an articulator in accordance with the cranial relation of the patient's upper and lower jaws detected by the dentist's facebow, thereby positioning the lower jaw model and upper jaw model relative to one another.
  • the dental technician selects a set of artificial teeth that fits the patient type, the jaw models, and their spatial arrangement.
  • the individual teeth are manually sequentially inserted and aligned on the jaw models with the aid of an adhesive such as wax, whereupon the bite of the later co-operating teeth is established.
  • the final result which is achieved by the interaction of the selection of the set of teeth, the positioning and alignment of the teeth and fine adjustment of the bite, depends exclusively on the Expertise and dexterity of the dental technician. After fitting this set of teeth to the patient in the dentist's office, the work returns to the dental technician.
  • the teethed models are removed from the articulator, embedded in a cuvette in plaster, and a negative model of each toothed jaw model is created.
  • the adhesive (wax) used to fix the teeth in positioning and aligning them in the jaw model is removed, leaving the teeth in the negative model.
  • the resulting by removing the adhesive cavity is finally filled with a polymer (plastic). After curing of the plastic, the full denture can be removed from the negative model, to which the negative model is usually destroyed.
  • a major disadvantage of the tooth set-up described in wax, that is, the procedure described above, is that it is very time-consuming and demands in particular the dental technician a high Mali of expertise and dexterity.
  • DE 198 38 238 A1 has proposed a method for the computer-controlled production of dental prostheses for the restoration of at least one tooth or jaw region, in which the conventionally produced upper and lower jaw models or parts thereof, taking into account the virtual axis of rotation of the articulator and specific reference points are digitized, so that the construction of the dental prosthesis by means of CAD and the manufacture of the dental prosthesis by means of CAM can subsequently be carried out computer-controlled.
  • this method is extremely complex and inaccurate, so that in particular the transmission of the digitally present spatial geometries of the denture on the virtual design and the implementation of the digital signals using CAM to the finished real dentures only inadequately possible. Above all, however, even a complete denture can not be produced by this method.
  • From DE 103 04 757 A1 discloses a similar computer-assisted method for the production of dental prostheses, in which the data collected by a surveying device for generating a medical Part, for example, a dental crown to be evaluated.
