Abstract:
1. A method for allocating prosthetic installation work between at least three parties where a dental situation and fixture applications therein are simulated on a computer screen by the first party, first components in connection with the prosthetic installation are produced by the second party with the aid of a recording and said simulation, second components are supplied by the third party, and the prosthetic installation is assembled and fitted by the first party by means of said first and second components, characterized in that the recording includes a first reading of an impression or prosthesis and a second reading of a portion supporting the prosthetic installation, in that the simulation includes collation of images or representations on the computer screen, which images or representations result from the first and second readings and on the basis of which the simulated fixture applications are constructed, in that the simulated fixture applications include chosen positionings in relation to said supporting portion, in that a model, e.g. of plastic, is produced, preferably by a stereolithopaphy method, by one of said parties, or a fourth party, in that the first components include an assembly template which can be applied to said substrate and is produced by means of the model and is intended for hole-forming members which are guided by the assembly template in the substrate in directions which correspond to the directions of the chosen positionings, in that the first components include a unit forming part of the installation, e.g. a dental bridge, which is provided with attachment holes which connect to the holes formed in the substrate, in that the second components include the fixtures which are applied in said formed holes by the first party, and in that the second components also include securing members for securing the unit in said applied fixtures.
