Anchor slide unit for dental prosthesis incorporates a primary part with matrix crown, and secondary part with patrix, sleeve, slit, sprung section, cam and groove

摘要

The anchor slide unit for a dental prosthesis produces a detachable connection between a primary part with matrix (1) on the side of the residual tooth, and a secondary part with the patrix of the unit on the prosthesis side. The patrix is fixed to the matrix by an anchor connection. A sleeve (3) forming the matrix is radially sprung, has a lengthwise slit and is detachably inserted into the primary part. The sleeve's lower radially sprung section (33) takes the patrix with a matching end section. The outer casing of the matrix sleeve has a cam (32) and has a peripheral outer groove (35) taking an elastic ring.
