LATCH matrixholding DENTAL MATRIX AND WITH SUCH matrixholding retainer

摘要

Group utility model relates to the die and the die retainers dental matrices. The technical result increasing the reliability of fixation by clamping across the template tooth height. The retainer is formed of the integrally formed main body 1 with at least one groove 3 (the grooves can be performed by through a hole) at its rear 14 and upper 15 surfaces for connection with the jaws 4, a die, and the work portion 2 with a wedge-shaped protrusion 5, which are performed by the lateral surface 6 of the flat, cylindrical, etc. shape, to form at their intersection the ribs 7 (top), a wedge-shaped lug 5. The height of the wedge-shaped protrusion 5 is not greater than the height the main body 1, and its base 8 is coplanar with the surface 9 of the main body 1, the retainer. The wedge-shaped projection 5 may be performed with the through slot 3 and the compound from adjacent the main part 1 of the base 10 and tapered height and width of the front portion 11 of the protrusion 5. Couple klinoobrazuyuschego jaws of the die 4 is formed as an open ring, and is connected between a coil of the coil spring 17. one of the jaws is equipped with a ferrule 4 for connecting with a clamp, and the other ends with a groove 18 for the passage therethrough of the locking wedge. Jaws 4 a die equipped with hooks 19 for dental forceps. 2 bp f ly-14, ZP f-ly, 23 ill.
