ABSTRACT:
A method for determining the size, shape and position of a pair of upper central incisors for the production of dentures comprises the steps of covering the patient's upper gums with a paste, providing a series of representations of different pairs of upper central incisors and positioning different ones of these representations on the paste until a representation of desired size and shape is selected and secured to the paste by way of an adhesive at a chosen location thereon. The paste carrying the selected representation is then removed from the patient's mouth, whereby dentures can be produced on the basis of the positioning of the upper central incisors on the paste roll and on the selected model of upper central incisors, as the latter determine the models of the remaining teeth of the dentures. The method can also be used for the determination of an artificial tooth used for a dental implant, a bridge or a crown. Also, a method is proposed for determining the vertical dimension of occlusion with a rest position clearance also for the production of dentures, wherein lower central incisors are positioned with respect to the patient's facial characteristics.
