Estimating the term…
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. The instrument, together with the axially fixed second sleeve, can be inserted in the continuous recess and is guided and/or aligned in the template via the outer surface of the second sleeve, the surface being adapted to the inner surface of the recess.
An apparatus comprising an instrument for preparing or executing insertion of a dental implant, a template configured to be placed on a bone or tissue surrounding the bone, said template or a first sleeve arranged in said template having a through-recess configured for passage therethrough of at least part of said instrument, an axially displaceable second sleeve that in a basic position is axially fixed with pre-specified retention force by means of automatically releasable connecting elements and wherein when the retention force is exceeded said connecting elements are automatically releasable whereupon said second sleeve is axially displaceable on said instrument, and said instrument together with said axially fixed second sleeve being insertable into said through-recess and thereupon being guided and/or oriented in said template via the exterior surface of said second sleeve.
