Description
Technical field
The invention belongs to dentistry technical field, is related to a kind of method for activating surface of tooth implant.
Background technology
Oral implantology grows up from eighties of last century five, the sixties, popularizes very much abroad, and is sent out in China
Exhibition is horizontal relatively low.Dentistry plantation is that a plantation nail is planted at the position of patient's agomphosis, then installs corona, equivalent to growing
One new tooth, convenience attractive in appearance, is comfortable on.Will not be as installation fixed denture abrasion healthy tooth, it is not required that activity justice
The hook of tooth and the auxiliary of denture fixing device.Domestic dentistry implant market is monopolized by foreign countries substantially, and price is high.And restrict state
One key factor of production tooth implant development is exactly the process of surface treatment of planting body.Surface treatment work for tooth implant
Skill, people attempted a variety of methods, such as polishing, spraying hydroxyapatite, spraying titanium slurry etc..After in planting body implantation tooth
Be brought into close contact with dentale, Gegenbaur's cell still in chemotactic, therefore people have generally received to be processed into mat surface in implant surface, from
And planting body and synosteosis are more beneficial for certain chemotactic space to Gegenbaur's cell.It is threaded with the development of dentistry implantology
Rough surface structure planting body be more beneficial for synosteosis turn into dentistry plantation circle common recognition.Wherein with Nobled's
TUniteTM (the porous titanium oxide structure of differential arc oxidation processing) and ITI (bulky grain sandblasting-two level nest hole knot caused by acid etching
Structure) it is most representative.The surface of planting body is modified the focus for also turning into studies in China, it is desirable to improves planting body by being surface-treated
Surface bioactive, with accelerometer facial bone sedimentation rate and form firm chemical bonding.But they have technical process
Complexity, production cycle length, cost is high, the deficiencies of bioactivity difference.Experiment is much also rested on to current, domestic handling process
The room stage.
The content of the invention
It is an object of the invention to provide a kind of method for activating surface of tooth implant, solves existing dental implant surface
The problem of bioactivity difference.
The technical solution adopted in the present invention is a kind of method for activating surface of tooth implant, tooth implant is carried out clear
Wash, sandblasting, acid treatment, clean again after, dental implant surface forms bioactivity, porous structure.
The features of the present invention also resides in,
Specifically include following steps：
Step 1, tooth implant is cleaned by ultrasonic oil removing；
Step 2, blasting treatment is carried out to the dental implant surface obtained through step 1 with bulky grain diamond dust, form micron
The big pit of level, then tooth implant is sequentially placed into acetone, 75% ethanol and distilled water and is cleaned by ultrasonic, dry；
Step 3, by through the tooth implant that step 2 obtains 0.09mol/L~0.13mol/L HF and 0.07mol/L~
0.11mol/L HNO3Mixed liquor processing 5min~15min of formation, distilled water are rinsed, dried, and surface is formed submicron order
Small rut；
Step 4, the tooth implant obtained through step 4 rinsed by purified water successively, 5%NaHCO3 solution ultrasound it is clear
Wash, purified water is rinsed, Micro90 degreasers are cleaned by ultrasonic, running water rinses, purified water is rinsed, water for injection is rinsed and given birth to
The tooth implant of the active porous structure of thing.
Oil removal process is cleaned in step 1 to be included：Respectively it is cleaned by ultrasonic 2 times using acetone, absolute ethyl alcohol, purified water, every time
4min~10min.
In step 2：Pressure during blasting treatment is 0.4MPa；A diameter of 10 μm~30 μm of big pit.
In step 3：A diameter of 0.2 μm~0.7 μm of small rut.
In step 4：5%NaHCO3 solution is cleaned by ultrasonic 2 times, and each time is 5min~10min.
Tooth implant is cylindricality or the threaded pure titanium implant of taper.
The device have the advantages that it is：
(1) method for activating surface of the invention, present invention hydrochloric acid and sulfuric acid mixing acid treatment, make use of mixed acid to titanium
Corrosion of metal acts on, there is provided good sandblasting dental implant surface pattern so that good rough surface is presented in tooth implant
Characteristic, further improve tooth implant bone junction interface bond strength.50%~75% sulfuric acid and 8%~20% salt
Acid concentration proportioning acid etching effect is preferable, and the acid etching step more than twice for making currently generally to use is reduced to once with regard to that can reach mesh
, shorten processing time, improve operating efficiency, reduce cost so as to fit in commercially producing；
(2) method for activating surface of the invention, without additional coating, avoiding introducing foreign substance, there may be biology danger
Evil, finds mainly to contain tetra- kinds of elements of Ti, O, C, N, no other impurities using X-ray photoelectron spectrum (XPS) analysis；And eliminate
After planting body implantation human body, risk that coating may come off.
Embodiment
