The interface bonding strength of the coating reaches 13 MPa.
Description
This utility model is the facial active titanio tooth implant of a kind of combination table, belongs to the dental prosthetic medical domain, relates to novel subperiosteal dental implant, is used for the dentition defect reparation that causes because of odontopathy, wound.
Anodontia directly has influence on the healthy and attractive in appearance of people, hinders pronunciation, and modern's work post tooth implantation technology makes the mistake tooth replantation become possibility.Tooth implant is made of hat stake and root of the tooth two parts, does substrate with pure titanium metal or titanium alloy, and root of the tooth is implanted in the alveolar bone, and short-term is installed the hat stake after stablizing maintenance, and edge is joined corona, finishes and loses the tooth reparation.Very complicated with the chimeric structure of fixedlying connected of root of the tooth convex-concave to the hat stake abroad, accessory is quite various, and the cost height is not easy to operate.Chinese patent CN1064610 is at titanium tooth substrate surface; with high-temperature plasma spraying hydroxyapatite bioactive ceramic coating; because of the intensity and the sinterability of hydroxyapatite all very poor; Bond Strength of Coating undesirable (being generally about 10MPa); show as coming off of coating clinically; influence serviceability, also need the equipment and the special atmosphere protection of large-scale costliness during making, the cost height.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and provides a kind of embedded structure simple, and antitorque commentaries on classics performance is good, anchoring strength of coating height, the good active titanio tooth implant in combination type surface of biology performance.
The purpose of this utility model can reach by following measure: combined bio activity glass ceramic coating titanio tooth implant, its substrate is made by pure titanium metal or titanium alloy, to be that convex-concave is chimeric with root of the tooth fixedly connected for hat stake, the interior six square groove tablings on hexagonal prism and root of the tooth top outside the bottom of hat stake, screw by the center is connected to an integral body by bolting, be the transition zone of thermal coefficient of expansion between titanium metal substrate and coating between the biological active glass ceramic porous coating of root surface and the titanium metal substrate interface, the threaded area of root of the tooth outer surface has at least two anti-grooves that reverse that axially are symmetrically distributed.
The purpose of this utility model can also reach by following measure: the form of thread of root of the tooth outer surface is that the main chemical compositions of rectangle biological active glass ceramic cellular face coat is CaO-P
2O
5-SiO
2-MgO, the main chemical compositions of transition zone is K
2O-Na

5-F.The thickness of implantation body's coating is the 30-10 micron, and pore diameter range is the 10-100 micron.
Description of drawings: Fig. 1 is this utility model structure chart
Fig. 2 is this utility model A-A profile
This utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2: combined bio activity glass ceramic coating titanio tooth implant, its substrate is made by pure titanium metal or titanium alloy, the interior six square groove tablings on hexagonal prism and root of the tooth (2) top outside the bottom of hat stake (1), screw by the center is fixedly connected as an integral body by bolt (3), the form of thread of the lower external face of root of the tooth (2) is rectangular teeth (8), and threaded area has three anti-grooves (7) that reverse that axially are symmetrically distributed.The surperficial agglomerating cellular coating of root of the tooth (2) is biological active glass ceramic coating (4), and main chemical compositions is CaO-P
2O
5-SiO
2-MgO, its sintering character is good, and the interface combination has good biology performance based on chemical bond.But coating (4) does not match with the thermal property of pure titanium metal or the titanium alloy-based end (5), and for solving this contradiction, adding a chemical constituent between coating (4) and pure titanium metal or the titanium alloy-based end (5) is K
2O-Na
2O-SiO
2-MgO-Al
2O
3-CaO-P
2O
5The transition zone of-F (6).High temperature sintering is sprayed on the transition zone of surface of metal titanium, and high temperature sintering is sprayed on the biological active glass ceramic coating on transition zone surface again, and its implantation body's coating layer thickness is the 30-100 micron, and pore diameter range is the 10-100 micron, more than the interface bond strength 13MPa.
During use, earlier root of the tooth is implanted in the alveolar bone, osseous tissue can grow into coating hole and anti-reversing in the groove, the boundary zone can form firm synostosis, plants physical ability and stablizes maintenance in a short time.After three months, the hat stake is installed, edge is joined corona, finishes and loses the tooth reparation, can exercise the masticatory function of normal tooth.
The utility model is compared prior art and is had following advantage:
1, the stake of planting body tooth and root of the tooth adopt that six sides are chimeric, radially right on screw fixed structure and the root surface rectangular thread The anti-groove structure of reversing that claims, the ability that has increased the bond strength of tooth-implanting and prevented reversing.
2, adopting biological active glass ceramic is face coat, and main component is fluorine voelckerite, wollastonite and a small amount of glass The glass phase, its sintering character height, the existence of element silicon and Trace Fluoride element makes planting body have higher biologically active. Biological active glass ceramic is not degraded in vivo simultaneously. Coating is durable, difficult drop-off.
3, between the biological active glass ceramic cellular coating of root surface and the substrate titanium interface, be to have the intermediate layer that good biological is learned performance, its thermal coefficient of expansion is between substrate titanium and coating, coating and substrate can be mated on thermal property mutually, can make the counterdiffusion of the various element phase of coating interface in sintering process, form the chemical bond combination by the boundary zone, Bond Strength of Coating is up to more than the 13MPa, help the stable and firm of coating structure, increased interface bond strength, can not peel off because of the local defect occurrence of large-area.
4, structure and making sintering process are simple, do not need the equipment and the special atmosphere protection of large-scale costliness, and be with low cost.
