METHOD OF MANUFACTURING ARTIFICIAL TOOTH ON SOCKET OF MATRIX OF CLASP DENTAL PROSTHESIS WITH LOCK FIXATION Russian patent published in 2011 - IPC A61C13/265 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely, to orthopedic dentistry and can be used in manufacturing removable clasp prostheses with lock fixation. Method of manufacturing artificial tooth on socket of matrix of clasp prosthesis with lock fixation includes manufacturing of one-piece matrix socket, application of external surface of socket of retention coating and formation of artificial tooth. External surface of matrix socket is given anatomical shape of tooth, retention coating is applied by method of plasma sputtering with further processing with chemical adhesive agent. On chewing and vestibular surface provided is space 1.5±0.1 mm and 1.0±0.1 mm respectively for facing composite material.

EFFECT: possibility to ensure optimal redistribution of chewing loading from facing layer on metal base of artificial tooth, create optimal thickness of matrix socket depending on type of lock fixation, strengthen adhesion of external surface of matrix socket with facing material to 61,7 MPa, which allows to avoid chipping-off of facing and considerably increase term of service of clasp prosthesis with lock fixation.
