ABSTRACT:
The selection of a dental anchor for insertion into a jaw bone of a patient is achieved utilizing a transparent transfer sheet carrying on a first side thereof a plurality of removable pictorial representations of dental anchors of different sizes. The transfer sheet is superimposed over an X-ray to position different ones of the pictorial representations over a site of the X-ray where a dental implant is to be installed. When a pictorial representation of desired size has been selected, a second side of the transfer sheet opposite the selected pictorial representation is rubbed in order to transfer the selected pictorial representation onto the X-ray. Each of the pictorial representations includes indicia indicative of a dimension of the associated anchor. The pictorial representations are magnified in size relative to the X-ray to provide a factor of safety.
