The enveloped portion is found in the dental implant, while the enveloping portion is arranged in the dental cast device. The enveloping portion has a cavity of size and shape to match with the enveloped portion. A bulge projects from the head and has a hexagonal section, while the retainers of the enveloping portion consist of flanges to be inserted in recesses forming the reciprocal retainers of the enveloped portion. The recesses are provided in walls of the hexagon and are spaced a little from each of its edges. ^ EFFECT: enabled fast and strict recording of the dental implant position in a jaw to be immediately transferred to a working model. ^ 15 cl, 6 dwg |
