ABSTRACT:
A connecting device is included in oral and extra-oral prostheses of the type which is partially implanted in bodily tissue, primarily bone tissue, by means of a specifically designed anchorage unit (a fixture). The connecting device provides more favorable stress and force distribution between the implanted and the outer portion of the prosthesis located peritissually. The connecting device includes an outer, cylindrical sleeve-shaped patrix (6) for connection to the outer prosthesis portion, for example by casting, and is designed to surround a central spacer screw (3) of a spacer (1) connected to the anchorage unit. The device connects through lower base (11), to a collar-shaped portion (4, 5) of the spacer (1) by the intermediary of a resilient member (7).
