Abstract

Abstract A surgical drill (1) made of metal, for instance made of surgical grade stainless steel or carbon steel, intended for use when implanting cylindrical implants into bone tissue, preferably dental implants made of titanium. The body (3) of the drill (1) is coated by a thin layer of titanium nitride (TiN). A circumferential band is etched on the body for indicating the depth of the hole bored. The implant has a predetermined insertion length.

Claims Analysis

Total Claims: 1
Claim 1
Independent Claim 145 words
In combination, a metallic surgical drill (1) adapted in use to drill a bore into a bone tissue structure and a cylindrical implant for insertion into the bore characterised in that the implant has a predetermined insertion length and that the drill has a body (3) with an envelope surface which is coated with a thin, brightly coloured layer of titanium nitride on which there is etched a circumferential band (8; 9; 10; 11) which is of a colour which is darker than the titanium nitride layer and which further has a boundary line disposed at a predetermined distance from a predetermined datum point on the body corresponding to the predetermined insertion length of the implant whereby drilling of the bore by the drill into the bone tissue structure up to the boundary line results in the bore having a correct depth for the implant.
