Abstract

For static fixation of the jaw relation in intraoral recording, a recording instrument set is used that includes a pin holder with a vertically adjustable stylus for placement in one jaw, and a writing or recording plate with an alignment clamp mounted on it for placement in the other jaw. The stylus, initially vertically locked on the pin holder, can be locked in stationary fashion in the ascertained jaw relation in the alignment clamp. By means of this locking, the jaw relation is keyed, and the use of hardenable material such as molding plaster previously used for this purpose can be dispensed with. This dental treatment process can thus be done in less time and with less material, and once the jaw relation has been keyed it is retained reliably until further processing in the dental laboratory. This locking can be attained particularly advantageously if a pan bearing that receives the lower end of the stylus, embodied as a writing ball, is provided in the alignment clamp. This affords simple options for locking that are based essentially on the fact that after the introduction of the writing ball the entry cross section of the pan bearing is reduced far enough that the writing ball is firmly retained in the pan bearing.
