Direction.
A kind of denture manufacturing process, as shown in Figure 1, including the following steps:
A, design and tooth mould 8 is made；
A1, design tooth mould 8；
Tooth mould 8 is placed on the platform of conducting wire analyzer, observation model, according to the line of observation of each abutment, agomphosis distribution and clinic
Data carries out the design of bracket 9, snap ring 92 etc. and determines common path of insertion, then draws each abutment card with crayon on tooth mould 8
The trend of ring 92, the position of inner step, connecting plate each structure member of brackets 9 such as shape figure；
A2, undercut and lining wax are filled up；
According to 9 figure of casting frame drawn, undercut and buffer area are filled up with undercut wax, with the sheet wax pair with a thickness of 0.5mm
Reticular structure region is padded, and forms apparent inner step.
A3, delineation connecting plate trim line；
The fine groove that a depth is 0.2-0.3mm is delineated along the trim line of connecting plate with sharp keen instrument or suitable bistrique.
B, after 8 adequate preparation of tooth mould, refractory material model is replicated with agar on tooth mould 8, refractory material can be phosphoric acid
Salt refractory material.
C, wax pattern is made on refractory material model, wax pattern is with the blank of the bracket 9 of waxed work, also referred to as artificial tooth
Thick embryo；
As shown in Fig. 2, simply being illustrated the structure of bracket 9 first, usually before the production method for specifically introducing wax pattern
Bracket 9 includes base 91, the netted connector 93 for the snap ring 92 of maintenance and for connecting with reparation tooth, snap ring 92
It is arranged on abutment, snap ring 92 and connector 93 are by one entirety of formation after the connection of base 91.
Step c specifically comprises the following steps:
C1,92 wax pattern of snap ring is made first, the size of snap ring 92 is determined according to the size of abutment；
C2, then production base 91；
C3, netted connector 93, complete ceroplastic production are finally made.The wax pattern stable structure to complete, is conducive to increase
The success rate for adding bracket 9 to cast.
D, sprue-way is assigned, sprue-way is assigned in wax pattern and fills founding materials alloy mixture.
E, filled wax pattern is placed in casting circle and carries out embedding treatment in pressure cooker, the embedded material in casting circle can
Material is embedded for phosphate；
Step e specifically comprises the following steps:
Cleaning and ungrease treatment first are carried out to wax pattern before e1, embedding, water or alcohol gently brushing wax pattern surface is dipped in writing brush, washes away
Grease, then cleaned up with clear water, finally dry up；By cleaning wax pattern, it can prevent impurity subsidiary in wax pattern from bringing casting circle into
It is interior, to improve wax pattern surface to embedding material adsorption capacity and lubricity, to form clear, smooth casting mold inner wall；
E2, the center that wax pattern is placed in casting circle, the side wall of wax pattern distance casting circle will have at least gap of 5mm, the top of distance casting circle
Portion will have the gap of 8-10mm, to accommodate embedded material；
E3, the phosphate for modulating paste embed material, pour into casting circle；
E4, it will fill in the merging pressure cooker of the casting circle after embedding material, and adjust pressure to 4-10Pa, so that the embedding material of emulsus exists
Interior coagulation forming is enclosed in casting, completes embedding；The bubble generated when embedding is discharged using the air pressure generated in pressure cooker, solves bracket
Caused bubble is difficult to the problem of being discharged when 9 embedding, and bracket 9 is not allowed to be also easy to produce metal tumor in surface in casting, so that bracket 9 is in
Existing inside and outside clean smooth surface, prevents the deformation of bridge and bracket 9.
E5, it is taken out after 3-5 minutes in pressure cooker, completes embedding.Since the setting rate of the embedding material of emulsus takes
Certainly in the height of ambient temperature, temperature is higher, and setting rate is faster, therefore is 3 minutes when summer, is 5 when winter
Minute, it can not only make to embed material solidification sufficiently in this way, and pressing time can be prevented too long, destroy the knot of embedding material
Structure.
F, casting is enclosed and casts the wax pattern in circle and baked, made the fusing of melt film material, overflow, form mold cavity.
G, it casts in 9 casting device of casting mold Stent Implantation after baking, while being passed through into 9 casting device of bracket
Inert gas.
9 casting device of bracket can be high frequency centrifugal casting machine, and high frequency centrifugal casting machine is to melt metal using electromagnetic heating,
Molten metal in crucible is got rid of in the mould cavity in wax pattern using centrifugal force simultaneously, so that bracket 9 is formed, in the present embodiment
Bracket 9 used in material be cobalt chromium, nickel chromium triangle and precious metal alloys.
Inert gas can be nitrogen, can also all have protective effect to metal for other inert gases, the two such as argon gas, this
Nitrogen is used in embodiment.
Step g specific steps are as follows:
G1, will bake after 9 casting device of casting mold Stent Implantation in；
G2, it is passed through inert gas into 9 casting device of bracket, enables the casting and forming under the protection of inert gas of bracket 9；
And the pressure that is passed through of inert gas makes the concentration of the inert gas in device if the hypotony for 0.5 Pa-1Pa
Too low, the protective effect of generation is smaller, if pressure is too big, be easy to cause the waste of inert gas；
G3, casting mold is taken out after the completion, and naturally cool to room temperature, complete the production of bracket 9.
It is passed through nitrogen into 9 casting device of bracket when due to casting, nitrogen drives the air in crucible away, in metallic perimeter
Protection gas is formed, so that the ingredients such as contained chromium, molybdenum, silicon, nickel, beryllium, cadmium are not easy to be oxidized in metal, is maintained intrametallic each
Content of material does not change, and enhances the ductility for the bracket 9 to be formed, so that metal fatigue is less likely to occur bracket 9, thus
So that the intensity of bracket 9 is higher, it is not easily broken, increases its service life.
H, it is polished with sander bracket 9, to correct the tubercle and overlap on bracket 9.
I, bracket 9 is electrolysed with electropolisher, polished, so that the surface of bracket 9 is more smooth.
