Abstract: The invention relates to an arrangement comprising an instrument for the preparation or execution of the insertion of an implant, particularly dental implant, comprising a template, which can be placed on a bone or the tissue surrounding said bone, particularly mucous membrane. The template, or a first sleeve arranged within the template, comprises a through-recess, through which the instrument can be guided at least partially. The arrangement is to be refined in order to provide exact alignment and guidance of the instrument and easy handling. For this purpose, it is proposed to arrange a second sleeve that is axially displaceable on the instrument. Said sleeve is axially fixed in a base position by means of automatically releasable connecting elements with predetermined retaining force such that when the retaining force is exceeded, the connecting elements can be automatically released and the second sleeve can be axially displaced on the instrument.

Abstract: A method for the three-dimensional determination and digitization of a plaster- or positive-model, in particular for the production of replacement teeth, with improved handling and costs. According to the method, a plaster- or positive-model is clamped in a mounting with a defined orientation and irradiated by means of a radiation source; the radiation reflected by the plaster- or positive-model is recorded and evaluated by a scanning unit. Separation information is generated, and defined movement of the plaster- or positive-model relative to the radiation source takes place along an axis (y), approximately perpendicular to the direction of radiation and linking the displacement with the separation information. The invention also relates to a device for carrying out the method.
