Abstract
In an arrangement for anchoring a threaded implant (1) in jawbone (2) by means of a screwing instrument (6), use is made of an implant which, at its upper part, is provided with an anchoring hole (1c) for a screw (5) intended to secure an element or fixture holder (4) that can be attached to the implant. The centre axis of the anchoring hole is inclined in relation to the longitudinal axis (1b) of the implant. The element is provided with means (4d) for cooperation with the instrument (6). The element and its means of cooperation permit application of the instrument in a way which ensures that the axis of rotation (6d) of the instrument essentially coincides with a continuation of the longitudinal axis (1b) of the implant.
Claims11
A threaded implant, anchoring device, comprising:
- an implant having a threaded anchoring hole at an upper end for securing an element attached to said implant by a securing unit, the center axis of said anchoring hole being inclined in relation to the longitudinal axis of said implant;
- and
- a screwing instrument, wherein
- said element has a means for cooperating with said screwing instrument so that said screwing instrument rotates about the longitudinal axis formed by said implant.
A threaded implant, anchoring device, comprising:
- an implant having a threaded anchoring hole at an upper end for securing an element attached to said implant by a securing unit, the center axis of said anchoring hole being inclined in relation to the longitudinal axis of said implant;
- and
- a screwing instrument, wherein
- said element has a first portion anchored by said securing unit of said implant,
- said element has a second portion, separate from said first portion, cooperating with said screwing instrument.
A method of using an element to screw an implant into a bone, comprising the steps of:
- attaching an element to a threaded implant by means of an anchoring hole in said implant and a securing unit, wherein the center axis of said anchoring hole is inclined in relation to the axis of rotation of said implant;
- using the cooperation between said element and a screwing instrument to screw said implant into the bone;
- applying said instrument so that its axis of rotation essentially coincides with the axis of rotation of said implant;
- and
- screwing said implant into the bone.
