Description
Technical field
The present invention relates to a kind of oral cavity lower jaw practice models, are specifically related to a kind of lower jaw oral cavity mould with mandible incisor
Type and injection moulding method.
Background technique
Mandible incisor be clinical oral treatment in important feature, lower molar, premolar teeth position operative treatment before
Doctor must confirm the position of mandible incisor with various means (mainly x piece), could start to perform the operation, to avoid surgical procedure
Middle intrusion mandible incisor damage mandibular nerve and blood vessel.So the lower jaw oral cavity model of most of simulation bedside practices requires
There is mandible incisor feature.
The mandible incisor forming method of existing lower jaw oral cavity model is: the part of preforming mandibular canal form,
It fixed in silica gel former, is then cast into former, is formed after waiting solidification, the defect of this forming method is with liquid resin
Need manual implementation, the silica gel former service life short price of casting is the liquid resin price of casting, therein solid
Agent smell weight is toxic, and the time for being cured to dimensionally stable is long, and a set of casting mold can only at most produce 5 sets within 24 hours one day
Model, such final production low efficiency, high production cost.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention proposes a kind of lower jaw oral cavity model with mandible incisor and is injected into
Type method can be improved the production efficiency of lower jaw oral cavity model, and under the premise of guaranteeing the use function of client, production efficiency can be mentioned
Height is to plastic 500 sets of daily 24 hours of one group of mold, the general moulding resin of model charge.
The technical scheme of the present invention is realized as follows:
A kind of lower jaw oral cavity model with mandible incisor, including soft tissue, several teeth, mandibular, tongue bottom and lower jaw
Nerve channel, the mandible incisor is looped around the front side and left and right sides at the tongue bottom, and passes through several connection strengthening ribs and institute
It states tongue bottom to be fixedly connected, the tongue bottom, the mandible incisor and the connection strengthening rib pass through a tongue bottom injection molding one
It is injection molded into tongue bottom parts；The mandibular surround and is wrapped on front side and the left and right sides at the tongue bottom, and wraps described
Mandible incisor, the mandibular top surface have needed to form several tooth sockets, the tongue bottom parts and the lower jaw according to practice
Bone is mandibular tongue bottom combiner by a mandibular injection molding integral injection molding；The soft tissue wraps the tongue
Bottom and the mandibular top surface and front side and left and right sides, it is periodontal which, which extends to the part on the tooth socket inner wall,
Film, mandibular tongue bottom combiner and the soft tissue are soft tissue packet by an encapsulated injection molding integral injection molding
Glue component；The tooth is solidly plugged on the parodontium in the tooth socket.
Further, tongue bottom bottom surface is formed with for being fixed to the mandibular injection molding or the encapsulated injection
Positioning connection structure on the die cavity of mold or on imitative head mould is formed at bottom surface on front side of the mandibular and on left and right sides
Encapsulated slot.
Further, the mandible incisor include the supervisor that the second premolar teeth position is extended forwardly to from backteeth position,
The thick branch and ramuscule separated from the second premolar teeth position, the thick branch are chin pipe, and upper outside extends and is pierced by mandibular backward in direction；
Ramuscule is mandibular incisors nerve channel, and direction extends to front lower inside, is converged with the mandibular incisors nerve channel of opposite side.
Further, the material not phase of the material of the tongue bottom parts, the material of the mandibular, the soft tissue
Together, by there is the color of obvious color difference to distinguish, and position differentiation can be carried out by shooting X-ray film.
A kind of injection moulding method of the lower jaw oral cavity model with mandible incisor, includes the following steps:
A the front side and left and right sides at tongue bottom) are looped around by mandible incisor, and solid by several connection strengthening ribs and tongue bottom
Surely the form connected makes a set of tongue bottom injection molding；
B) tongue bottom injection molding is installed on injection moulding machine, chooses the dedicated plastic cement in tongue bottom, is injection moulded tongue bottom parts；
Injection pressure when the tongue bottom parts injection molding is in 20~200Mpa, and forming temperature is at 180~300 degree, and mold temperature is 20
~180 degree.
C it) surround and is wrapped on front side and the left and right sides at tongue bottom by mandibular, and wrap mandible incisor, mandibular top
Face is formed with the form of several tooth sockets, and Mandibular Morphology superposition Chong Die with both tongue bottom parts forms, under production is a set of
Jawbone injection molding；
D) mandibular injection molding is installed on injection moulding machine, the tongue bottom parts of forming are fixed on mandibular note
It penetrates in the die cavity of mold, chooses the dedicated plastic cement of mandibular, be injection moulded mandibular tongue bottom combiner；Mandibular tongue bottom combination section
Injection pressure is in 10~150Mpa when part injection molding, and forming temperature is at 180~300 degree, and mold temperature is at 20~100 degree；
E tongue bottom and mandibular top surface and front side and left and right sides) are wrapped by soft tissue, soft tissue extends to tooth socket inner wall
On part be parodontium form, make a set of encapsulated injection molding；
F) encapsulated injection molding is installed on injection moulding machine, the mandibular tongue bottom combiner of forming is fixed on
In the die cavity of encapsulated injection molding, the dedicated plastic cement of soft tissue is chosen, is injection moulded the encapsulated component of soft tissue；The encapsulated component of soft tissue
Injection pressure is in 10~150Mpa when injection molding, and forming temperature is at 180~260 degree, and mold temperature is at 20~100 degree；
G) the tooth insertion of forming is fixed in the tooth socket of the encapsulated component of soft tissue.
Further, tongue bottom bottom surface is formed with for being fixed to the mandibular injection molding or the encapsulated injection
Positioning connection structure in the die cavity of mold or on imitative head mould is formed at bottom surface on front side of the mandibular and on left and right sides
Encapsulated slot.
Further, the material not phase of the material of the tongue bottom parts, the material of the mandibular, the soft tissue
Together, by there is the color of obvious color difference to distinguish, and position differentiation can be carried out by shooting X-ray film.
The beneficial effects of the present invention are: the present invention proposes a kind of lower jaw oral cavity model with mandible incisor, can sufficiently expire
The needs of sufficient bedside practice simulation.
Lower jaw oral cavity model of the present invention is formed using injection molding, rather than the silica gel pouring mold of prior art forms,
It can only at most form within a set of silica gel mould of the prior art average 24 hours 1 day 5 set of model, and average 1 day of the invention 24 is small
When at least plastic 500 set of model.
90% or more the stock utilization that the present invention uses, and the stock utilization of the prior art is less than 70%.
The material that the present invention uses does not have volatile smell, and the curing agent group of the liquid resin of existing placingJi Shu
Point, have volatile flavor generation.
As long as product of the present invention cuts cast gate after forming out, and the prior art is also wanted after taking out in silica gel mould
There are a large amount of amendment overlap work, production efficiency is lower.
