Description
Technical field
The invention belongs to oral cavity titanium alloy tooth implant technical field, and in particular to a kind of titanium alloy dental implant surface changes
The processing method of property.
Background technology
Tooth implant, it is to be implanted into by way of surgical operation in the upper mandibular at human body agomphosis position, treats its hand
After art wound healing, the device of artificial tooth is repaired in installation at an upper portion thereof, plants root of the tooth of the body portion equivalent to dermal tooth, therefore Dental implantion
Fixation of the body for whole tooth serves vital effect, because artificial root of the tooth will be implanted in the alveolar bone of people,
So tooth implant must have good bio-compatibility, intensity and manufacturability, in order to which the bone tissue with people is incorporated in one
A bit, enduringly using heavy burden.
Dental implant materials mainly has Metal and Alloy material class (gold, 316L stainless steels (iron-chromium-nickel alloy), casting
Vitallium, titanium and alloy etc.) and two kinds of ceramic material class, generally use is medical pure titanium at present, and titanium has good
Good bio-compatibility, is referred to as biological metal, can be firmly combined together with the bone of people, this characteristic of titanium is claimed
It is to be taught to find 50 years last century by scientist Bu Luonei marks of Sweden for " synosteosis ".Then, titanium is applied to
Tooth implant, and other field is extend to, such as field of orthopaedics etc.；Allow titanium is more preferable, is quickly done with people's synosteosis, people
Substantial amounts of research and practice.The tooth implant of early stage is not surface-treated especially, maintains machining surface, Zhi Houwei
The more preferable bioactivity of tooth implant and osseointegration character are assigned to meet the Treatment need for shortening healing cycle, starts to apply
Surface coated treatment technology, by the material with bioactive properties it is attached to it (such as：Titanium starches sprayed surface and hydroxyl phosphorus ash
Stone coating surface).By this method obtain tooth implant have micron-nanometer multi micro-structural concurrently, solve surface texture with
The problem of base adhesion deficiency；But because planting body preserves Clinical practice to the end from being fabricated into, generally have one intersegmental
Every the time, tooth kind bigger by the chance of hydrocarbon pollution in air with the extension dental implant surface of holding time
The biological activity of implant is lower；Having research surface, newly its ratio of bone contact (BIC) of planting body of the processing without pollution can reach
To more than 90% and the pure titanium implant BIC of aging only less than 60%, and orthopedic implant is in mechanical environment and biofluid
Erosion collective effect under, coating easily comes off, dissolved, cause the bioactivity of material to reduce, service life shorten；In addition
One problem is additional interfaces between coating and matrix be present, makes Integrated implant maintain to complicate for a long time.Therefore, the surface of non-coating
Roughening attracts people's attention, surface texture technology, to obtain certain coarse surface, to increase surface area, can make bone with
Bonded area between planting body greatly increases, for example, patent " CN102232876 " is processed to tooth by way of sandblasting and acid etching
The surface of planting body is handled, and forms the multi level pit reduced step by step, improves the adhesion of tooth implant and alveolus.
The content of the invention
To overcome problems with present in prior art：In dental implant surface coating technology, face coat easily takes off
Fall, dissolve, causing the bioactivity of material reduces, the problem of with alveolar bone contact force difference；The invention provides a kind of Dental implantion
Surface treating method, by carrying out the processing such as acid etching, pickling and cleaning to dental implant surface, there is table so as to obtain one kind
Face is the tooth implant of the coarse structure of nanometer, tooth implant is obtained more preferable hydrophily, protein adsorption ability, has more preferable
Biological activity.
