Abstract
The invention discloses a method for preparing a porous structure on the surface of a pure titanium dental implant, which comprises the following steps of sand blasting on the surface of the pure titanium dental implant and double acid treatment so that a layer of multistage porous structure is formed on the surface of the pure titanium dental implant. By using the method, the porous structure prepared on the surface of the pure titanium dental implant has good bone tissue compatibility, and the combination intensity of the dental implant and bone tissue can be improved, so that long-term clinical success rate of the dental implant is improved, and the method has the characteristics of being simple in technology, easy in equipment machining, and capable of reducing the cost greatly.
Description
Technical field
The present invention relates to a kind of bioactive artificial tooth implant, be specifically related to a kind of method for preparing loose structure on the pure-titanium tooth implantation surface.Belong to A61C8/00 (2006.01) the I technical field in the International Patent Classification (IPC).
Background technology
The existence of the dentistry implantable bioartificial material loose structure that uses clinically can improve the interfacial effect between embedded material and the host bone, if the soft or hard tissue of near interface can both be grown in the hole, thereby make fibrous tissue and freshman bone tissue form the bonding state that interweaves.Like this, it can not only promote the interface to carry out normal metabolism, and has greatly improved the bond strength between timbering material and the osseous tissue.Studies show that, when the aperture of porous embedded material during at 15～40 μ m, can the grow into inside of implant of fibrous tissue; When the aperture was 40～100 μ m, the bone sample of non-mineral can be grown into; The aperture is when 150 μ m, for growing into of osseous tissue provides desirable place.Therefore, microcellular structure is one of focus of in recent years mouth cavity planting body biomaterial research to the Bioabsorbable of biomaterial.For example,
Publication number is " a kind of method at the fluorine-containing multistage pore space structure of pure-titanium tooth implantation surface preparation " that the application for a patent for invention of CN1985774 provides, it carries out sandblast with pure titanium implant, after the surface modifications such as the corrosion of sulphuric acid hydrochloric acid mixed solution burn into Fluohydric acid. nitric acid mixed liquor and immersion sodium fluoride, implant surface can form the pattern of the multistage pore space structure of one deck.
Publication number is " method that has bioactivity, porous structure in the preparation of pure-titanium tooth implantation surface " that the application for a patent for invention of CN1817319 provides, after it at first carries out the surface modifications such as sandblast, dual acid treatment, hydrogen peroxide and heat treatment with pure titanium implant, implant surface can form the pattern of the multistage pore space structure of one deck, the TiO on surface
2Layer is the anatase phase structure.
The preparation method that above technical scheme provides though can both shorten implantation body's one osseous tissue healing time, has obtained certain clinical efficacy, improves the clinical success rate of tooth implant.But the shortcomings such as its treatment process is complicated, and inconvenient operation and cost are higher.
Summary of the invention
The object of the invention is to solve the above-mentioned technical problem that prior art exists, pass through Improvement, a kind of method for preparing loose structure on the pure-titanium tooth implantation surface is disclosed, comprise pure titanium implant surface sand-blasting, dual acid treatment step, form the pattern of the multistage pore space structure of one deck on the pure titanium implant surface.Has good bone biocompatibility with method provided by the invention at the loose structure of pure-titanium tooth implantation surface preparation, can improve the bond strength of implantation body and osseous tissue, thereby improve the Long-term clinical success rate of tooth implant, it is simple to have technique, apparatus processing is easy, and characteristics that can the decrease cost.
The technical scheme that the present invention provides is: this method for preparing loose structure on the pure-titanium tooth implantation surface, it is characterized in that comprising the dual acid treatment step of implant surface blasting treatment and implant surface, wherein:
Described pure-titanium tooth implantation surface sand-blasting treatment step, at normal temperatures with bulky grain corundum piping and druming dental implant surface, described pure-titanium tooth implantation surface is through the sandblast of bulky grain corundum, pressure is 3-7bar, time 5-30s, apart from 20-200mm, make dental implant surface form irregular matsurface and micron-sized pit, for next step dual acid treatment provides a suitable pattern basis;
Described pure-titanium tooth implantation surface double acid treatment step is that pure-titanium tooth implantation is placed certain density mixed acid solution, heats 40-70 ℃ of processing, and the time is 5-20min; The taking-up distilled water flushing is dry, again puts into mixed acid solution, heats 40-70 ℃ of processing, and the time is 5-20min; The taking-up distilled water flushing is dry, makes its unfavorable defective of transforming the sandblast rough surface, forms simultaneously the pit of submicron order, the surface that obtains having bioactivity, porous structure, and this structure has the ability of inducing hydroxyapatite deposition.
The mixed acid solution of dual acid treatment pure-titanium tooth implantation of the present invention is the mixed solution of 20-30% sulphuric acid and 5-10% hydrochloric acid.
The optium concentration of dual acid treatment pure-titanium tooth implantation mixed acid solution of the present invention is: sulphuric acid 30%, hydrochloric acid 10%.
Dual acid treatment pure-titanium tooth implantation of the present invention, best treatment temperature is 60 ℃.
Compared with prior art, the invention has the beneficial effects as follows: the loose structure in the preparation of pure-titanium tooth implantation surface has good bone biocompatibility, can improve the bond strength of implantation body and osseous tissue, thereby improve the Long-term clinical success rate of tooth implant, it is simple to have technique, apparatus processing is easy, and characteristics that can the decrease cost.
