Mesh Plate for Dental Implant and Dental Implant Structure Having the Same. US Patent: US20100112522A1
Provided is a dental implant structure for recovering or improving function of a lost or damaged tooth. A mesh plate for a dental implant with a plurality of holes is loaded and fixed on an alveolar bone from which a tooth is lost. A barrier for preventing proliferation of an epithelium and a gingival connective tissue covers the mesh plate at a predetermined height from the mesh plate then, an alveolar bone can be regenerated from a blood clot flowed through the plurality of holes into a space defined by the mesh plate and the barrier as such, the mesh plate can be strongly fixed to the alveolar bone with the help of the regenerated alveolar bone. Furthermore, an upper implant structure fixed on an abutment protruding from the mesh plate can be strongly fixed to the alveolar bone.
This invention is about making bone for putting implant In this way, using the plate mesh mechanism and creating a pit for blood supply to texture, It is faster to repair, which in this case is similar to our invention however in my plan, the implant itself is in meshed form and its kind is titanium, pit of the mesh cause increasing osteoporosis with bone; afterwards, this matter causes more blood to go forth.
Titanium-mesh umbrella device for bone grafting. US Patent: US20060008773A1
A titanium-mesh umbrella for bone grafting used to combine with conventional implant and to hold bone graft in proper position during dental implant placement procedure, comprises: a titanium metal shank with one end as implant end and the other end having a pin hole at its center to form a mounting portion; a titanium-mesh with its surface having a plurality of screen meshes, wherein said titanium-mesh encircles an area with a diameter in horizontal direction and forms a projecting umbrella surface with a curvature in perpendicular direction, a rough surface being formed on said projecting umbrella surface, said umbrella type titanium-mesh being able to position quickly on the mounting portion of said metal shank to form an umbrella structure. Thus, the titanium metal umbrella can be positioned quickly during dental implant placement procedure, so that the guide tissue membrane can be securely attached, a space for bone graft growing can be maintained, and the operation duration can be shortened.
Use the base and enhance the resistance using a mesh plate titanium umbrella with pores, the invention is intended to bind, maintain, and repair bone growth in its place are the features of this invention; however, the point of similarity of the invention is the use of titanium as mesh; still, in my plan, the mesh is of titanium, but in this invention the mesh material is tantalum. Meanwhile, only one third of the median in this implant is mesh, also, my plan uses a 3D printer to build. The dimensions of the central part and the holes also differ, which causes blood supply and ultimately reparation more.
Dental implant and method for producing a dental implant. US Patent: US20140302460A1
In a dental implant comprising an implant body for the insertion into the jaw of a patient, and comprising a mounting section with a through-passage recess for a bolted connection that may be screwed into the implant body for the releasable attachment of the mounting section to the implant body, a superstructure, in particular a crown, is provided that at least forms the major part of an outer surface of at least one dental restoration. The mounting section and the implant body releasable mesh with one another via engagement elements that have at least one inclined plane departing from the circular shape, in particular a multi-sided profile or polygon. The superstructure and the mounting section are formed as an integral structural member made from the same material.
The implant body has an upper structure (crown) which forms the bulk of the external surface of the tooth restoration. Inclined curve, circular shape and polygon or polygon profile. The upper part and the installed unit are made as an integrated structural part for tooth restoration. Structurally, this inventive plan with my plan in regard of design is in this way, (the central part 1.5 mm of the upper is filled to full form a stronger implant, mesh hole dimensions are 0.05.), the sex, mesh and mechanism of the holes are different in our invention.
Dental implant with a trabecular porous structure. WIPO Patent: WO2010106241A3
The invention relates to a biocompatible dental implant having a trabecular porous structure and made of shape memory metal materials, capable of being quickly and completely colonised by the surrounding bone. Said implant consists of a solid main structure, a porous cylindrical sheath covering the main structure, a solid covering pad that covers the lower end of the main structure, and a solid removable pad that covers the upper end of said structure.
This dental implant is composed of porous and trabecular structures of metallic materials and covers the replaceable solid pad in the upper part of the structure. This invention has a structural difference in comparison with my plan and its different feature is in titanium holes and inside it, is full.
Implant surface with increased hydrophilicity. US Patent: 8309162
A method of increasing the hydrophilicity of an implant to be implanted into living bone. The method comprises the act of depositing non-toxic salt residuals on the surface of the implant by exposing the surface to a solution including the non-toxic salts. The method further comprises the act of drying the implant.
In the present invention, an implant hydraulic technique for live bone communication via moving non-toxic salts onto the surface of the implant by placing the surface, in the solution of non-toxic salts, it is used to dry the implant. This method is not in my invention and communication for repairing tissues has done through the pit on the mesh.
The invention relates to dental prosthodontics and is used in dentistry to perform dental implants in dental clinics. Implant components includes: center core or solid part, the place of abutment attachment, External implant surface which up to a depth of 0.8 mm is mesh and porous that are on the outer surface and are mesh like. Titanium mesh to a depth of 0.8 mm with an outer surface and porous form, the outer surface of the mesh has pores at a depth and width of 0.1. Also in the central part and 1.5 mm upper for more strength and integrity, implants are designed in full shape and solid. This implant is made via a three-dimensional printer using Titanium powder grade 5; As a result of, the laser welding between particles, this shapes of mesh acts as a scaffold; as a result of blood and osteoblastic cells penetrate into the mesh due to the pit in the mesh and the bone is tied to the implant in a grid-like manner.
Dental implants are designed to play the role of the missing tooth root, the base of the implant is placed directly into the jaw bone and a suitable replacement for artificial teeth and bridges. Problems related to the treatment of dental implants may be referred to as osteoporosis of the implant, which in fact forms a functional and structural relationship between the individual jawbone and implant. This process requires a few months after the surgery. When the integration is not done correctly, the implant is animated, that is to say, either it is completely disconnected or signs reveal of bone loss of 1 mm in the first year and up 2 mm in the second year.
Many factors may cause the implant to fail, including: incorrect implant placement, volume or low jaw bone density, damage to the tissue of around the implant, severe blow and ... In fact, the main concerns in the production of implants, increasing the implant surface to further bone osteoporosis, to this end, up to now, implant blasting and acid etching have been used, there is also a lack of primary stability in the implant. Another problem is the heat resistance created by screwing the implant in the bone. Ultimately, another issue is the low resistance to Unscrewing after several months of implant implantation. Maximum fracture of the implant in the abutment bolt to the implant and in the abutment collar, also at the edge of the collar implant, none of these areas are not component of meshed parts.
The components of this implant include: center core or solid part, the place of abutment attachment, External implant surface which up to a depth of 0.8 mm is mesh and reticular threads that are on the outer surface and are porous mesh like. Titanium mesh to a depth of 0.8 mm with an outer surface and pitted form. In practical terms, this dental implant is similar to other specimens and replacement for defective and missing teeth. The placement method of this implant in jaws is not different from conventional methods in general.
This fixture is implanted inside the jaw bone. This fixture is made according to the patient's jaws in several diameters and lengths; afterwards, reassuring of osseointegration, prosthetic stages of the implant begins, which is called the prosthetic phase. Other implants have disadvantages, including the poor connectivity and the integration of living tissue and bone with implants (poor osseointegration) that cause implants to lose or fail in some cases after a while. The way to build this plan is to use the technology of 3D printing via titanium material, the mesh implants are made up to a depth of 0.8 mm from the implant surface. The central part and the 1.5 mm upper are designed to strengthen implant in full shape and mesh holes are 0.1 mm. As mentioned, this implant is made using a titanium 3D printer.
Materials for making this implant are Titanium Grade 5 powder particles; As a result of, the laser welding between the particles, a scaffold is created, in describing the use of this type of titanium; in fact, grade5 is non-plated titanium, but via the combination of aluminum and vanadium into a hard alloy which it is much more harder than grade4, the higher the grade, the more titanium will be harder and It is more resistant to the occlusal stresses. The mesh status in this design makes the mesh play the role of a scaffold that blood and osteoblastic cells penetrate through the pores. In fact, the bone is integrating with implant in reticular form that implant's contact surface is greater by the ingestion of living tissue within the cavities and this matter increases the strength of the implant in bone and decreases the percentage of implant failure.
The effect of lack of bone resorption, due to increased surface area and bone remodeling inside the mesh; hence the outer surface is full of macrophages and inflammatory cells and osteoclastic cells, bone resorption decreases. It should be noted that this method reduces the Unscrewing of implant fixture rate after 2 months, as well as the final load time of the implant.
Increased implant contact with blood and bone-making cells, thereby increasing the implant contact surface with bone.
An increased of primary Implant Strength in the bone due to increased contact level and live tissue dipping decompressed into the pit.
Reducing the waiting time for the final load of the implant.
Via integrating the bone inside the implant grid, the ultimate strength of the bone in the implant is increased.
Decrease the percentage of implant failure due to lack of osteoporosis, which is due to increased surface area and bone deflection made inside the implant mesh, because the surface is full of macrophages and inflammatory cells of the bone-eater.
With the involvement of reticulated bone in the implant, the possibility of unscrewing disappears after 2 months.
Due to the perforated threads (screws) (heat, damage and press in the tissue) diminish and threads are like a piercing knife and it's easier to screw in the tissue and resist in front of it then decline heat and trauma.
