  • This method may be termed x indirect' molding.
  • a major drawback of indirect molding method is its complexity, and thus considerable cost. Both methods require the person taking the mold of the patient's face to be well skilled in the technique. It is important, for instance, not to apply excessive pressure when applying the mould. This would deform the face and result in a mask not fitting well. Neither of these methods is suited for the industrial production of individually adapted facial masks. The present invention seeks to overcome this important problem.

  • the contact-less determination of the topography avoids the face being deformed by excessive pressure. This provides for a perfect fit. In the case of a nasal mask, it is most important to obtain a perfect fit to the nose. Therefore the contact-less determination of the topography of the nose itself is central to the invention.
