Abstract: A method of making a metal one-piece custom post member for non-parallel rooted teeth, including preparation of two root canals of the tooth by using a drill, making a funnel-shaped parallel fixing of entries in the root canals, inserting two posts made of burn-out plastic and sized to the root canals, into the canals, such that upper ends of the posts extend out therefrom, each plastic post having a body shaped as a partially flattened round stick, providing a flattened circle cross-section, one end thereof forming an enlarged cap shaped similarly to the body, treating upper ends of the posts that extend out of the canals with a self-curing resin to bind the posts together to form a plastic one-piece custom post member, removing the plastic one-piece custom post member from the tooth, casting a metal one-piece custom post member of the same size and dimensions from the plastic one-piece custom post member such that the metal one-piece custom post member has two metal posts extending therefrom, each being suf

Abstract: The dental impression tray for optional partially toothless jaw and toothless jaw with implants consists of a basic impression tray (1) and of a paired impression tray (2) freely arrangeable and positioned upon it, whereat the tray (1) is executed basically as a grooved horseshoe-shaped profile (3), whose side edges (4) are thickened with the purpose of strengthening, and the paired impression tray (2) is executed as a stiff horseshoe-shaped U-profile, which rests exactly on the outer thick edge (4) of the tray (1) so that between the trays (1) and (2) a space (6) is formed, which can accept a tooth with the impression material, and the thin-walled profile (3) of the tray (1) is foreseen for making holes (7) by handy dental tools at optional places in accordance with the state of the treated jaw.
