Definitions
- the present invention relates to a biocompatible monomaterial dental implant having a particularly rapid integration with the surrounding bone.
- the present invention more particularly relates to a dental implant that can be adapted to a dental prosthesis.
- the present invention thus relates to a dental implant that can be used for purposes of reconstructive surgery, in particular as a maxillofacial implant that can be put in place in certain cases, as well as its prosthesis, during the same surgical procedure.
- a dental implant is used to make a removable and / or fixed dental prosthesis, in order to restore to a patient, partially or totally edentulous, a chewing function, oral comfort, and aesthetics.
- the implant creates stable, resistant, effective, non-iatrogenic and durable anchors in the maxillary or mandible of a patient.
- the implant is a cylindrical or frustoconical sleeve-shaped piece, provided with an external thread, a bore or well provided with an internal thread, and a head with an imprint to one from its ends.
- the external thread is optionally self-tapping and directly allows the insertion of the implant by screwing into the bone of the upper or lower jaw of the patient.
- the internal bore allows positioning on the implant a prosthetic system, also called abutment, by screwing into the internal thread. The abutment then receives the dental crown protruding into the oral cavity.
- Patent FR 2,747,031 describes implants, buried or not buried, solid titanium whose more or less elaborate model is intended to improve the consolidation in the bone of the maxillary or the mandible. Radial holes and flats are made on the side of the end implanted in the bone. Such implants make it possible to have a good laying accuracy but are not very favorable to good bone consolidation.
- Another design of an implant is based on the presence of a structuring and resistant axis, for example in shape memory alloy, surrounded by various coatings, including a rough external coating, for example from projected metal, by example in hydroxyapatite. But the lack of cohesion of the different layers between them leads frequently, during the establishment, to a deterioration of the outer coating rough or porous.
- the patent FR 2 796 265 describes an implant made in particular of solid shape memory NiTi metal alloy, coated with an outer layer of a second porous metal.
- nickel may be toxic in case of release.
- the object of the invention is to overcome the disadvantages of the prior art by providing a dental implant quickly integrable into the bone system of the upper jaw and the mandible, to perform the installation of this implant, and possibly that of the corresponding prosthesis, during the same surgical procedure.
- the object of the invention relates to a dental implant comprising a biocompatible porous mass in which is arranged at least one receiving bore for an intermediate piece on which the dental prosthesis is fixed.
- the biocompatible porous mass consists of a single material with trabecular structure providing communication between the exterior of said porous mass and the interior of said porous mass.
- the biocompatible porous solid is made of porous titanium.
- the biocompatible porous solid is made of porous tantalum
- the biocompatible porous solid consists of porous NiTi.
- the biocompatible porous solid has an open porosity of between 17% and 87% with pore sizes ranging from 75 ⁇ m to 500 ⁇ m.
- the external dimensions of the porous mass, buried in the bone mass correspond to those of the bore made in the bone mass of the maxilla or the mandible.
- the porous mass comprises an external thread intended to block said implant in the bone receptacle.
- the porous mass comprises a penetration end facilitating the penetration of said implant into the bone mass.
- the dental prosthesis 1 is intended to replace a totally missing tooth.
- This dental prosthesis 1 comprises a dental implant 2 according to the invention on which is fixed a connecting piece 3 ensuring the positioning of a abutment and a crown 4, for example ceramic or enameled metal , corresponding to the shape of the tooth to be replaced.
- the dental implant 2 has a generally cylindrical or frustoconical shape by having an end of penetration 6 which enters first into the bone of the jaw during the surgical placement of the implant 2.
- the penetrating end 6 has, for example, a rounded, oblong, frustoconical or pointed shape.
- the dental implant 2 comprises at least one well or a blind central bore 8 intended to receive the connecting piece 3 and opening at the opposite end of the perforation end 6.
- the connecting piece 3 is provided with a polygonal head 9 for the positioning of the crown 4.
- the dental implant 2 is made of a biocompatible porous mass consisting of a single material with a trabecular structure. It should be understood that such a biocompatible porous mass thus has a network of intercommunicating channels that provide communication between the outside and the inside of the porous mass.
- the trabecular structure opens between the outer surface of the dental implant and the central bore 8. It thus turns out that this open porosity trabecular structure accelerates colonization of the implant for tissues. bone and after consolidation, creates an intimate link between the bone mass and the heart of the dental implant. Osteoblastic colonization is very fast.
- the biocompatible porous mass 2 is made of porous titanium.
- the biocompatible porous mass 2 is made of porous tantalum.
- the biocompatible porous mass 2 is made of porous NiTi.
- the porous material constituting the biocompatible porous mass 2 has an open porosity of between 17% and 87% with pore sizes ranging from 75 ⁇ m to 500 ⁇ m.
- the porous material may be obtained in various ways, in particular by plasma spraying, by compacting and / or sintering techniques allowing the use of powders or by deposition, either in the vapor phase (physico-chemical vapor-phase process by plasma spraying), or in electrolytic solution (electroplating or electroplating process).
- honeycomb constitution of the material itself confers on the implanted part characteristics with sculpting effect filling, at the time of implantation, the self-tapping function.
- the body of the implant 2 can be provided with an external thread which facilitates the screwing of the implant into the bone mass, which will facilitate the blocking thereof in the correct position so that a prosthesis can be mounted in the same surgical time while a definitive consolidation takes place in the weeks following said intervention.
- the external dimensions of the porous mass 2, buried in the bone mass correspond to those of the bore made in the bone mass of the maxillae or the mandible.
- the shape of the porous mass 2 is adapted to each patient.
- the biocompatible porous mass 2 comprises a bore 8 threaded or not, adapted to receive the connecting piece 3 provided with a thread to ensure the attachment of the implant with the prosthesis.
