Definitions
- the invention relates to the field of medicine and medical technology, namely to bone implants. These are implants that replace or complement the bone tissue, fully or partially fixed in the bone tissue or connect parts of the bones.
- Implants from inorganic materials which are most often used as bone tissue implants, can be divided into two large groups - metal implants and implants made from materials based on oxides, in particular aluminum oxide, zirconium oxide, silicon oxide.
- Metal implants are widespread after the discovery of osteointegration of titanium (Branemark, 1969). Pure titanium and its alloys (Ti with V, Al, Nb, Zr additives) are still used as the basis for implants most often. To improve the biological compatibility of the surface of titanium implants are often modified. Sandblasting, etching and oxidation increase the microroughness and hydrophilicity of the surface of the titanium implant and lead to an increase in the rate of integration of the implant with bone tissue.
- the advantage is chemical resistance.
- ceramics containing polycrystalline alumina Heimke, 1975.
- monocrystalline aluminum oxide is also known (Hirabayashi, 1978). The compressive and tensile strength and chemical resistance of monocrystalline alumina is very high.
- Implants made of oxide ceramics based on ZrO2 have high strength and high aesthetic qualities; they are second in frequency after titanium implants.
- Yttrium-stabilized zirconia-based materials have high chemical and biological resistance, high strength, relatively low Young's modulus (Yilmaz, 2007).
- Bone implants based on silicon oxide have been known since the use of 45S5 bioglass of the composition SiO2-P2O5-CaO-Na2O (Hench, 1971).
- Bio-glass can be used in the form of powder, as a filler for bone plastics when filling bone defects.
- the osseointegrated bioglass is replaced with live bone tissue. Initially it was assumed that osteointegration induces the presence of P2O5 and CaO in the bioglass composition, which approximates the bioglass composition to the bone hydroxyapatite composition, but later it was found that phosphorus-free and calcium-free silicate glasses also have high osteoinductive properties (Hench, 1979).
- Silicate bioceramics of such compositions have excellent compatibility with surrounding tissues and higher strength than that of bioglass.
- bone implants are made in whole or in part from silicate rocks or natural or artificial mineral aggregates with a dense, tangled-fibrous or fine-crystalline structure, commonly known as “jade”.
- titanium implants strength, ability to osseointegration, well-established medical protocols, long experience of use.
- the disadvantage of metal, including titanium implants, is the electrochemical activity of metals, which can cause various complications when using implants made of titanium and its alloys (Pozhitkov, 2015).
- compositions with hydroxyapatite or bioglass to titanium implants improves the osteoplastic properties of the implant and can reduce the electrochemical activity, but this effect is not long due to resorption of the applied surface layer.
- Aluminum oxide is very durable, but biologically inert, has a high Young's modulus of elasticity and a positive zeta potential at physiological pH. This can lead to difficulties in osseointegration and bone resorption over time with prolonged use of the implant.
- Silicate bioglasses have a high osteoinductiveness and osteoconductiveness, however, they have low strength, are brittle and are susceptible to resorption during prolonged stay in the bone tissue. These properties make it difficult to use them as a base for non-resorbable bone implants. Lithium-disilicate and apatite-wollastonite silicate bioceramics have a higher strength than that of bioglass, but at the same time have a reduced ability to osteointegration.
- bone implants are made of silicate mineral aggregates and rocks with a dense tangled-fibrous or fine-crystalline structure, commonly known as “greed” ( jade).
- jadeite jade Na (Al, Fe) Si2O6, jade (jade jade) Ca2 (Mg, Fe) 5Si8O22 (OH) 2, xonotlite (xonotlite jade) Ca6 (Si6O17 (OH) 2), vesuvianite (California jade) Ca10 (Mg, Fe) 2Al4 ((OH) 4 (SiO4) 5 (Si2O7) 2), bovenite (new greed) (Mg, Fe) 3 (OH) 4Si2O5, pectolite (Alaskan Jade) NaCa2 (Si3O8 (OH)), hydrogrossular (Transvaal Jade) Ca3Al2 (SiO4) 2 (OH) 4.
- jads are hydrosilicates. They are translucent, appear through in a thin layer, during processing they acquire a characteristic rough matte surface. Since ancient times, jads were highly valued in the stone-cutting business; tools were made of them (knives, axes) and objects of art (cameos, figurines, jewelry). By mechanical properties, these mineral aggregates can compete with titanium and steel, and surpass many alloys in compressive strength. However, the properties of greeds related to the possibility of integration into bone tissue did not attract the attention of researchers.
- the structure of the jades includes silicon oxide, which makes them promising in terms of biocompatibility and osteointegration capabilities.
- the fibrous structure of these silicates provides the elasticity and micro-rough surface necessary for the formation of a strong bond with the bone tissue.
- Jads are dielectrics, are not involved in electrochemical reactions, are hydrophilic, have a negative zeta potential under physiological conditions. It is precisely the complex of properties that made it possible to hope for the high quality of bone tissue implants from greases in accordance with the present invention.
- Implants of bone tissue from greases according to the present invention have high mechanical characteristics, high hydrophilicity, high biological compatibility, ability to osseointegration, low electrochemical activity, high aesthetic characteristics.
- An additional advantage of implants from greases are their dielectric properties. The lack of electrical conductivity reduces problems during MRI, CT and other medical and other procedures related to the transmission of electrical signals. The complex of properties allows the use of bone tissue implants from greeds in surgery, orthopedics, and dentistry.
- An exemplary and non-exhaustive list of implants made according to the present invention made from jade includes implants for bone substitution, bulk bulk fillers in the form of granules for inclusion in the composition for filling bone defects, bone screws, implants for bonding bones, fixing implants or for implants, implants for reconstruction of the skull, as well as orthopedic implants, percutaneous osseointegrable implants, dental implants.
- the group of orthopedic implants includes implants of the hip joint, implants of the hip joint, and implants spine, including vertebral and intervertebral disc implants, radial head implants, thumb implants, implant you for osteotomy (high tibial osteotomy).
- Particularly preferred orthopedic implants are joint implants, in particular the hip joint implant and the knee joint implant.
- a hip joint implant may be a head prosthesis and a diaphysis prosthesis (a leg of an endoprosthesis or a diaphysis of a femur) and an acetabulum prosthesis.
- the tibial and femoral components of the knee joint may enter the knee implant.
- the next group of implants from greases according to the present invention is percutaneous osseointegrable implants (endo-prostheses), which are integrated on one side into the bone of the distal part of the joint, their extraosseous part extends beyond the body through the patient’s tissues and skin, and the external part of the implant is used to fix external exoprostheses.
- endoexoprostheses as well as for orthopedic implants, the high strength of implants from greases is of decisive importance.
- a significant advantage for enoekzoprostheses from greases is the low electrochromic activity and the electrically insulating properties of such implants.
- the group of percutaneous osseointegrable implants includes endo-prosthesis for the legs, endo-prosthesis for the hands, endo-prosthesis for the fingers, endo-prosthesis for cosmetic operations.
- the group of medical devices related to dental implants includes a dental implant (screw, cylindrical, conical or plate), a dental abutment, a dental implant with an integrated abutment, a dental crown, a dental implant with an integrated abutment and a crown, a dental beam, a dental insert, a dental pin.
- a dental implant screw, cylindrical, conical or plate
- a dental abutment a dental implant with an integrated abutment
- a dental crown a dental implant with an integrated abutment and a crown
- a dental beam a dental insert
- a dental pin a dental pin
- the dental implant from the jade can be screw, cylindrical, conical or plate-shaped, collapsible or combined with an abutment.
- a collapsible implant the attachment of the dental abutment to the implant is done with an internal screw.
- the dielectric and mechanical properties of the implant from the jade provide electrochemical isolation of the internal mounting screw from biological body fluids. This allows the use of various materials, not only titanium, but also steel and other alloys, for fastening parts of a collapsible dental implant.
- Dental products made from the jaw are also capable of osteointegration with bone tissue of the tooth and / or jaw, such as a dental crown, dental insert, and dental pin.
- Both a tooth root implant, an abutment, and a crown can be made from white jade or matched to the patient's teeth. Consumer, in particular cosmetic, characteristics of such implants for the smile zone surpass the consumer characteristics of metal implants, all other conditions being equal.
- a preferred dental implant is an osteointegrable bead made of a jade for attachment to the alveolar process.
- the shape and dimensions of the beam are selected for the patient, on the alveolar process they prepare a platform for contacting the beam with bone tissue, a recess can be made corresponding to the shape of the lower part of the beam.
- a beam in which there are holes for fastening can be attached to the bone through the holes provided with the help of a prepared set of one or more screw endosseous implants or bone screws. Occurring osseointegration leads to subperiosteal or endosseum-subperiosteal implantation of a combined complex of a beam and a screw implant or bone screw.
- the combined implant is securely attached to the alveolar process, and bone grafting can be minimized.
- This implant is later used as a basis for fixing dentures, it evenly distributes the chewing load on the contact area of the beam with the bone.
- the use of such constructions is justified for the case of implantation in the area of the molars, or for the case of bone tissue of 3 or 4 types, or for the case of an alveolar bone volume insufficient for endosseous implantation.
- a particularly preferred dental implant is a dental implant combined with an abutment, which can be used in a single-stage implantation protocol.
- the crown is fixed immediately after implantation or after successful implant engraftment.
- the use of an integrated implant increases the convenience for the doctor and the reliability of the dental prosthesis for the patient.
- a further simplification of the implant design is a single monoblock artificial white tooth tooth, in which the endosseous implant, the abutment and the dental crown are combined into a single medical product. It can be a product from a standard size range for further turning in place, or it can be individually made to order according to patient sizes.
- Example 1 Made from pectolite jade granules bulk bulk filler for osteoplasty. Granules are sterilized, mixed with autologous bone chips, implanted in a bone defect according to an agreed protocol.
- Intervertebral disc implant It is made according to the required shape and size from vesuvianite, otherwise called Californian jade, sterilized, implanted according to an agreed protocol.
- Example 3 Implant for reconstruction of the skull. It is made according to the required shape and size from bovenite, or new jade, using CAD / CAM technology, sterilized, implanted according to an agreed protocol.
- Example 4 Acetabular endoprosthesis of the hip joint. It is made according to the required shape and size from jade, or jade jade, sterilized, implanted according to an agreed protocol.
- Example 5 Made a combined head and leg of the hip joint endoprosthesis. It is made according to the required shape and size from jade, sterilized, implanted according to an agreed protocol.
- Example 6 The femoral component of the knee joint endoprosthesis. It is made according to the required shape and size from xonotlitic jade, sterilized, implanted according to an agreed protocol.
- Example 7 Screw subgingival endosseous dental implant. It is made according to the required shape and size from hydrogaster, sterilized, implanted according to an agreed protocol. It is used as an artificial tooth root when implanted into the alveolar process using a 2-step protocol.
- Example 8 Dental screw endosseous implant with an integrated abutment. It is made according to the required shape and size of white jade, sterilized, implanted according to an agreed protocol for use in a single-stage dental implantation in the smile area.
- Example 9 A single monoblock artificial tooth cutter, in which an endosseous screw implant, an abutment and a dental crown are combined. It is made according to the required shape and size of white jade, sterilized, implanted according to an agreed protocol for use in a single-stage dental implantation in the smile area. The crown is ground in place.
- Example 10 Osteointegrable beam from white xonotlite, attached to the alveolar process through the holes in the beam using a screw implant from xonotlite.
- the beam is attached endoosally-subperiostally, on the seat in the bone tissue, prepared according to the shape of the lower part of the beam.
- the beam compensates for the lack of bone tissue in the smile area, serves as the basis for dentures.
- Bone implants made by their jade, can be used in such areas of medicine as surgery, orthopedics, traumatology, and dentistry.
