PCT No. PCT/GB89/01057 Sec. 371 Date Mar. 13, 1991 Sec. 102(e) Date Mar. 13, 1991 PCT Filed Sep. 8, 1989 PCT Pub. No. WO90/02531 PCT Pub. Date Mar. 22, 1990.A dental proosthetic construction is releasably attached at opposite ends to abutment teeth (T). At least at one end, the attachment is by means of a connector comprising a pin (4) and socket (6). The socket has an opening (10) onto the space between the abutment tooth and the prosthesis, the opening continuing over a side of the socket extending longitudinally of the pin. The pin can thus be engaged in the socket by a relative movement transverse to the pin. The pin and socket are then retained in engagement by a releasable latching arrangement (14). The engagement of the pin and socket permits relative translational movement in a direction that varies the spacing between the abutment tooth and the prosthesis but prevents translational movement in other directions. The engagement also permits relative angular movement between the pin and socket about axes transverse to the direction of the relative translational movement but prevents other angular movements. |
