Method for preparing material for forming artificial teeth - involves using at least two parts, each with patrix and matrix

摘要

At least two basic pieces (1) are used, each of which comprises a prim. part or patrix (2) forming a fixed part of the artificial tooth, and fixable to the upper or lower jaw, e.g. tooth, crown, bridge union, implant, etc., and a sec. part or matrix (3) which is fixed to the removable part of the artificial tooth. The prim. and sec. parts are releasably joined to one another by a friction pin (8) engageable in holes (6). The sec. part is firstly prepared in accordance with a master model, and then holes (6, 11) are bored in the two parts of the basic pieces. Each prim. part (2) is tried on the patient, enabling a fixation impression to be produced, from which a master model is then made. USE - To prepare basic material pieces for the prodn. of artificial teeth.
