Abstract
A dental implant for anchoring in a bone structure comprising a head intended to support a dental prosthesis and a threaded root of cylindrical substance, in which the threaded root has an internal cavity and a lateral orifice through which this internal cavity opens out on the external lateral face of the root. The axial position of this orifice is such that when the implant is in position, this orifice opens out on a medullary zone of the bone structure
Claims15
Dental implant for anchoring in a bone structure, comprising a head intended to support a dental prosthesis and a threaded root of cylindrical substance, wherein the threaded root has an internal cavity and at least one lateral orifice through which this internal cavity opens out on the external lateral face of the root , the axial position of this orifice being such that when the implant is in position, this at least one orifice opens out on a medullary zone of the bone structure
Kit designed for fitting a dental implant in place, comprising:
- an implant according to any one of the preceding claims;
- a biocompatible hardenable fluid;
- a device for indicating the position of the lateral orifice of the implant;
- a hollow needle injection device with which, when the implant is in place, it is possible to inject the biocompatible hardenable fluid through the bone and into the internal cavity of the implant.
Method for fixing a dental implant in a jaw bone, which method comprises the following operations:
- drilling a hole in the jaw bone from its cortical wall as far as a medullary zone in such a way as to form an alveolus with the dimensions of an implant;
- screwing into place an implant whose threaded root has an internal cavity, at least one lateral orifice connecting this internal cavity and the external lateral face of the root, the axial position of this orifice being such that when the implant is in position, this at least one orifice opens out on a medullary zone of the bone structure;
- inserting a hollow needle through the jaw bone as far as the alveolus;
- injecting a biocompatible hardenable fluid into the internal cavity of the implant;
- distributing the hardenable fluid in the volume around the prosthesis, in the lateral orifices and in the internal cavity of the implant;
- partially withdrawing the hollow needle;
- distributing the hardenable fluid in the medullary zone of the jaw;
- leaving the hardenable fluid to harden.
