Bone implant eyebolt which is intended on the one hand to form an artificial tooth root and on the other hand to reduce bone fractures, and which can be used in ear, nose and throat treatment

摘要

Device for fixing an implant eyebolt to the bone in order to hold in position a tooth prosthesis, a hearing aid, and to reduce bone fractures. It consists of a cylinder 1 made of metal of the "Pure titanium for medical use" type, provided in its upper part with a flat-headed screw 4 having a slot 5 so that it can be manoeuvred by a screwdriver, and provided in its lower part with two cylindrical pins 2 for locking the implant to to bone. Prior to the positioning of this implant eyebolt, a bore is drilled with a bone-drill bur of the dimension of the eyebolt with a stop, a grinding bur with stop for the lateral and circular grinding/burring of the lower part 9, and a bone fissure bur with a stop for burring two small lateral walls. The device makes it possible to hold in position, by means of implant 12, a tooth prosthesis, a hearing aid, and to reduce bone fractures by locking the implant eyebolt to the bone, and the device permits osteointegration in the parts left empty by the burring and grinding.
