Description
Technical field
The present invention relates to a kind of preparation methods of dental implant, are a kind of low elasticity film amount high strength titanium conjunctions specifically
The preparation method of the one-part form Immediate prosthesis dental implant of gold.
Background technique
Since Branemark the 1960s establishes synosteosis theory, restorative procedure of the Dental implantion as anodontia
It is developed rapidly, Dental implantion has become a kind of clinical repair technology of maturation, and the dental implant that the whole world uses every year reaches
30000000 sets or more, early stage is mostly European and American developed countries, developing country such as Brazil, China, with the rapid development of economy, tooth
Explosive growth is also presented in the usage amount of planting body.
Planting body production material experienced the development from gold-stainless steel-casting vitallium-titanium alloy and pure titanium
Journey, the pure titanium generally used currently on the market have many advantages, such as high intensity, low heat conductivity, nonmagnetic, good biocompatibility, simultaneously
Pure titanium also has preferable mechanical property such as elasticity modulus low compared with other materials, and fatigue strength and yield strength are higher.But it is pure
Titanium material also has disadvantage, and containing harmful substances such as micro aluminium, vanadium, (people is close with the elastic membrane amount mismatch of body bone tissue
Matter flexible bone film amount is 20-30Gpa, and the elastic membrane amount of pure titanium is 110Gpa), it be easy to cause " the stress screen of bone regeneration around implant bone
Cover " effect, masticatory force etc. concentrates on Dental implantion, and bone tissue is led to bone resorption or osteanabrosis, finally drawn by less than stimulation
It plays planting body fracture or loosens, Dental implantion is caused to fail.Therefore, selecting suitable planting body to prepare material is also that plantation is successful
It is crucial.
Summary of the invention
It can be used in that edentulous space is less than normal or the low elasticity film amount of labial teeth gum bone the purpose of the present invention is to provide a kind of
The preparation method of the one-part form Immediate prosthesis dental implant of high strength titanium alloy.
The present invention is realized using following technological means: a kind of preparation side of titanium alloy one-part form Immediate prosthesis dental implant
Method includes the following steps:
1) long 3.0m is used, the β type TLM titanium alloy material of diameter 6.0mm is machined into length 10mm, diameter 3.0mm
One-stage dental implant, the TLM titanium alloy material is grouped as by each group of following weight ratio example: Ti30%, Nb12%:
Surplus is Zr；
2) SLA surface treatment is carried out through over mechanical processing One-stage dental implant by above-mentioned, aperture is big after processing on surface
Small is 1-3 microns.
Preferably, the SLA surface treatment process in the step 2) includes the following steps:
A) silica of 40 mesh being placed in sand-blasting machine, adjusting pressure is 0.4Mpa, abrator head and implant surface are protected
That holds vertical 45mm or so sprays 25s apart from uniform rotation；
B) after sandblasting, dental implant is placed in purified water and dehydrated alcohol, respectively ultrasonic wave 15min., then will
Dental implant is put into air dry oven and is dried 105 DEG C, 30min.
C) dried dental implant acid etching: is placed in the hydrochloric acid that mass concentration is 19% and the sulphur that mass concentration is 49%
In acid blend, in 60 DEG C of heating water bath acid etching 30min, it is then put into ultrasonic cleaning 15min in purified water, uses purified water
After repeated washing 4 times, dental implant is put into air dry oven and is dried 105 DEG C, 30min.Implant surface morphosis
It is one of the factor for influencing Osseointegrated implants, because a large number of studies show that rough surface is more advantageous to than smooth surface promotes bone knot
It closes, shortens planting body clinic bone healing time.The sandblasting and acid etching that the present invention takes, planting body obtain under bulky grain sandblasting
10-30 microns of hole is obtained, this some holes, which has, to be promoted into ostosis, and acid etching rear surface forms 1-3 microns of micropore, and acid etching is also
Implant surface impurity can be cleaned, hydrophily, more conducively synosteosis are increased.
The invention also discloses the titanium alloy one-part form Immediate prosthesis dental implant that above-mentioned preparation method is made, dental implants
The base station being arranged by implant and thereon is integrally formed, and the surface of the implant is uniformly arranged equidistant isosceles trapezoid external screw thread,
The dental implant rear end top center is equipped with a round platform hole, and a hexagonal hole is arranged in the lower section of the round platform hole,
A blind screw hole is equipped with below the hexagonal hole.
Preferably, the isosceles trapezoid external screw thread screw pitch is 0.6-0.8mm.
Planting body of the invention is for edentulous space to be less than normal or the one-part form planting body of labial teeth gum bone, patient only need one
Secondary operation avoids the pain of patient's second operation；Implant surface uses sandblasting and acid etch technique, through surface roughening treatment
Aperture be 1-3 micron, be conducive to that early stage is stable and quickly healing, to reach energy early stage load after planting body implantation, at once
The purpose of reparation.
