Apparatus and method for determining and recording of information relating to the positions of the optimal center line, the vertically - and horizontally in the guide as well as the cutting line or - edges of the vorderzaehne of a patient

摘要

A system useful for recording or providing information concerning the optimal esthetic position and angulation of the anterior teeth of a dental patient during restoration of teeth with crowns or the construction of dental prostheses, the system utilizes five principal components:PPa multi purpose positioning face bow including curved side arms adjustably interconnected by a linakage device for suspension from the ears of a patient with the linkage device and an associated bracket positioned below mouth level,PPthe bracket adapted to support either, an adjustable transparent screen in a substantially vertical plane and positioned relative to a patient's mouth to obtain a transferable prescription of the position and angulation of anterior teeth for use on an articulator in another place, or a bite fork jig providing support for a interchangeable and invertible bite fork and an adjustable nose pointer, or a camera positioning frame for mounting a camera in fixed and constant relationship with the patient's anterior reference point and mouth to provide a photographic record, and a photographic frame for holding said photographic record for use with an articulator holding a model of the patient's teeth reproducing in the articulator some of the facial environment of the teeth.
