[Determination of prospective tooth positions by means of model analysis--the Staub Cranial System]

In modern reconstructive dentistry, practitioners delivering removable or fixed dentures still face problems when determining prospective tooth arch and tooth positions. Certain anatomical planes and reference lines, such as Camper's plane, interpupillary axis, etc. have been established as a guide. However, the ability and experience of the dentist remain essential. Adjusting the tooth arches is time-consuming and, therefore, expensive. To simplify and standardise the procedure, dental technicians and dentists may use the Staub Cranial System. It consists of three devices (Positionierer Ortho 1A, Einbaustativ Ortho 2A and Cranialstativ Ortho 3A) and the Staub Cranial software. With its aid, dental casts are surveyed and a penta-area is calculated. This penta-area, three-dimensionally adjusted, may define exactly the site and position of the dental arch. In this article, the Staub Cranial System is presented and documented by a clinical case.
