Abstract

An arrangement including an instrument for the insertion of a dental implant including a template placeable on a bone or surrounding tissue. The template, or a first sleeve arranged within the template, includes a through-recess, through which the instrument can be guided. The arrangement enables exact alignment and guidance of the instrument and easy handling. A second sleeve that is axially displaceable on the instrument is provided, and axially fixed in a base position through 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. The instrument, together with the axially fixed second sleeve, can be inserted in the continuous recess and is aligned in the template via the outer surface of the second sleeve, the surface being configured relative to the inner surface of the recess.
