Definitions
- the invention relates to dental implants.
- Titanium dental implants have good mechanical characteristics and very good osseointegration, but one of their most annoying drawbacks is the complexity of the operating technique, which is also carried out in two stages, and the delay of six months before setting in office. These difficulties arise from the establishment of a metallic electrogalvanic bridge between the intraoral environment and the endosseous environment. Putting the implant in place and then putting it into operation therefore constitute two real surgical procedures, increasingly performed by specialists and no longer by the dentist.
- the problem is solved according to the invention which provides a mixed dental implant in which the transmucosal head is made of high density sintered ceramic, or bio-glass, or titanium isolated by a coating of ceramic or any other bio-inert material or bio-active, this head thus being electrogalvanically insulating, and the endosseous body is made of titanium, this body being extended so as to also constitute the transmucosal head, when the latter is made of titanium isolated by said coating.
- the electrogalvanic insulation of the titanium infrastructure in its superosseous part will therefore be either a transmucosite head made of high density sintered ceramic or bio-glass, mechanically assembled with titanium and bonded, for example, using medical glue. of the cyano-acrylate type, or a coating of titanium by a plasma projection of ceramic, for example alumina, or zirconium oxide, or any other bio-inert or bio-active material (bio-glass for example) , or by an application on titanium of these same materials, followed by a firing transforming them into enamel.
- Another object of the invention is an accessory for fitting and fitting the implant, which will be described later.
- Figure 1 is an enlarged perspective view of a first embodiment of the dental implant according to the invention.
- FIG. 2 is a view in axial vertical section of this implant in place in the gum and the maxillary bone of a patient.
- Figure 3 is an axial vertical sectional view of a second embodiment of the implant.
- Figure 4 is a perspective view of a fitting accessory and implant equipment.
- the implant 1a shown in FIGS. 1 and 2 comprises a transmucosal head 3a, for example made of high density sintered ceramic, such as aluminum oxide or zirconium oxide or a mixture of these oxides, and a body endosseous 2a made of titanium intended to be screwed or impacted in the maxillary bone 10 of the patient, after having crossed the gum 11 in which said head will be housed.
- a transmucosal head 3a for example made of high density sintered ceramic, such as aluminum oxide or zirconium oxide or a mixture of these oxides
- a body endosseous 2a made of titanium intended to be screwed or impacted in the maxillary bone 10 of the patient, after having crossed the gum 11 in which said head will be housed.
- a hole 4 of polygonal, for example triangular, section, open in the intraoral environment 16 is provided in the central part of said head, above an axial housing 5a provided in said body and of the same polygonal section. that the hole 4.
- the hole 4 and the housing 5a are intended to receive the tool for placing the implant by screwing or impacting as well as, subsequently, the pivot of the prosthetic suprastructure.
- the section of the hole 4 is slightly greater than that of the housing 5a so that the head 3a does not risk being damaged by the fitting tool, the section of which is adapted to that of the housing 5a.
- a hole (not shown) can be drilled in the lower part of the implant, in a conventional manner, and the formation of bone tissue through this hole will ensure the non-rotation of the implant after bone healing, but it is preferable that the The implant does not have such an orifice, so that it can, if necessary, be removed and replaced.
- the hole 4 drilled in the head 3a ends in a larger cavity 7, of circular section for example, in which is housed an element 6 of the same section as the cavity 7, in one piece with the body 2a in titanium and protruding above it, and the element 6 is drilled, in line with the hole 4, to constitute the top of the housing 5a of polygonal section.
- the connection between the cavity 7 and the projecting element 6 can be ensured by a layer 8 of glue, for example a cyano-acrylic glue, or by any other suitable means.
- the protruding element 6 has a height less than the height of the cavity 7 to form an expansion space 9 intended to compensate for the difference in the coefficients of thermal expansion of the titanium and the sintered ceramic.
- the titanium body 2a penetrates into the maxillary bone 10 while the head 3a crosses the mucosa 11.
- We therefore benefit from the mechanical and osseointegration qualities of titanium while the head in ceramic provides the excellent electrical, chemical, galvanic, and aesthetic characteristics (absence of black stripe at the base of the tooth) of a ceramic implant, allowing remarkable tolerance of the gum as well as the electrochemical isolation of titanium compared to intraoral environment 16.
- the presence of a ceramic head flush with the mucosa also makes it possible to use the operating techniques for placing a ceramic implant, much less long and heavy than those for a titanium implant.
- Figure 3 illustrates a variant 1b of the implant.
- the titanium body 2b is extended upwards so as to also form the head of the implant.
- This titanium head has a ceramic coating 3b, for example a coating obtained by a direct plasma projection of alumina, or a coating of any other bio-inert or bio-active material, of bio-glass for example. With the coating 3b, the titanium head becomes the equivalent of a head 3a made of sintered ceramic or bio-glass and it allows the same electrogalvanic and chemical protection to be obtained.
- the hole 4 and the housing 5b are, in this variant, in direct extension of one another.
- the implant fitting and equipment accessory shown in FIG. 4 fulfills the function of positioning and screwing key (for example) of the implant.
- This faceted part 15 serves as a gripping means for engaging the rod
- Said accessory is however mainly used to equip the implant in place, since the part 15 of its head, after the implant has been placed, can be cut in any suitable manner to become a parallel abutment or inlay-core with the other elements of the prosthetic or dental suprastructure of the patient and who will receive the prosthetic tooth, and the fact that its rod 12, reintroduced into the housing 5a or 5b, will then constitute the pivot of the tooth.
- the neck 14 of the head 13 by its lower face with an icy polish, forms a perfect seal with the upper emerging face of the implant; its side, also in glossy polish, opposes fixing of dental plaque.
- the whole of the head 13 participates in the isolation of the body 2a or 2b in titanium, by removing any electrogalvanic bridge between the implant and the prosthetic or dental suprastructure.
