Producing a structure that can be sintered to make a three-membered dental bridge comprises differential electrophoretic deposition on a positive model and two positive impressions

摘要

Producing a structure that can be sintered to make a three-membered dental bridge, by electrophoretically depositing particles from a suspension onto a form immersed in the suspension, comprises using a form comprising two positive impressions, especially of tooth stumps, and a positive model, especially of a tooth to be replaced, where the positive model is subjected to a higher voltage and/or has a higher conductivity than the positive impressions. An independent claim is also included for apparatus for producing a sinterable structure as above, comprising electrodes that can be applied to the positive impressions and the positive model.
