Problems solved by technology

[0003] Commercially available bioresorbable screws, such as those used for bone plates, are mostly not suitable for anchoring implants in the jaw region
In particular, most commercially available screws are designed to hold solid and strong parts and are therefore less suitable for holding thin, flexible, flat structures such as foils or membranes made of collagen, or for porous molding

Embodiment Construction

[0085] figure 1 A side view of a screw 1 according to a first embodiment of the invention is shown.

[0086] The overall length of the screw (including head 2 with drive 7) is generally preferably 3 to 20 mm. shown here with Figure 5 and 6 The shorter version preferably has an overall length of 5 to 10 mm.

[0087] The screw 1 has a head 2 consisting of a cap 5 and a drive 7 . Adjacent to the head 2 is a shaft 4 which, in the exemplary embodiment, merges directly into the thread 3 .

[0088] The cap 5 is formed in the shape of a plate and, in this embodiment, is rounded on the top side 9 .

[0089] The bottom side forms a preferably planar contact surface 6 which fixes the implant during normal use.

[0090] The drive portion 7 is adjacent to the cap 9 .

[0091] By means of the drive part 7, the screw 1 can be inserted into a handling tool (not shown). The drive 7 is preferably fixed here by means of a handling tool so that it cannot fall out.

Abstract

The invention relates to a screw which is used in particular in oral dental surgery. The screw is made of a bioresorbable material and has a drive that can be broken off by means of a predetermined breaking point and / or has a thickened shank below the bearing surface of a cap of the head of the screw.

Description

technical field [0001] The invention relates to a bioabsorbable screw for fixing implants, which is used in particular in the field of dentistry. In particular, the invention relates to screws for fixing bioabsorbable membranes and implants for filling bone defects. The invention also relates to a kit with an implant and at least one bioabsorbable screw. Background technique [0002] In practice, bioabsorbable implants, such as collagen foils, are usually fixed with nails or wires, which have to be removed in a complex manner after fusion of the implant. [0003] Commercially available bioabsorbable screws, such as those used for bone plates, are mostly not suitable for anchoring implants in the jaw region. In particular, most commercially available screws are designed to hold solid and strong parts and are therefore less suitable for holding thin, flexible, flat structures such as foils or membranes made of collagen, or for Porous moldings.
