Description
Technical field
The present invention relates to dentistry teaching mode field, more specifically relate to the application of a kind of super hard gypsum in preparation anthropomorphic dummy alveolar bone, for dentistry teaching teaching and operation training.
Background technology
At present, adopt rigid plastic simulation alveolar bone both at home and abroad mostly.The major advantage of rigid plastic is, enough hardness and intensity are arranged, and is easy to moulding; Its major defect is that complex process needs the particular process facility, has penetrating odor to produce in the process.Rigid plastic can not be degraded under field conditions (factors) voluntarily, easily causes environmental pollution, and the processing of discarded object causes difficulty.Not seeing the application of a kind of super hard gypsum in preparation anthropomorphic dummy alveolar bone by retrieval is disclosed or uses.
Summary of the invention
The objective of the invention is to be to provide the application of a kind of super hard gypsum in preparation anthropomorphic dummy alveolar bone.This material has the form of simulating normal alveolar bone preferably, and the damaged profile of various bones under the pathological state, and can be used for making with the simulation alveolar bone is the various teaching modes of support.
Because alveolar bone is the important component part of periodontal support tissue, therefore, alveolar bone also is that one of indispensable parts of tool are touched in each section's teaching of dentistry.Selecting suitable material is the key of making the alveolar bone model.Desirable cast material should possess following pacing items:
(1) source is abundant
(2) low price
(3) be easy to moulding
(4) easy to operate
(5) enough hardness and intensity are arranged
(6) nontoxic, have no irritating odor
(7) indeformable
(8) be easy to store
Super hard gypsum is mainly used in the preparation of gypsum tooth in the Oral Repair therapeutic process, not yielding because of its intensity height, plasticity is good, can simulate the variation of tooth fine structure, and clinical practice is increasingly extensive.
In order to achieve the above object, the present invention adopts following technical measures: at first make the alveolar bone die with silicon rubber, again the perfusion of super hard gypsum paste is formed the alveolar bone model.This method comprises the following steps: in order successively
(1) alveolar bone rigid plastic model is fixed in model box base central authorities;
(2) will answer mould with silicon rubber A, B component by 1: 1 mass ratio mixing 40-60 second on de-airing mixer;
(3) on bobbing machine with in the slow injection model box of silicon rubber, until the rigid plastic model is flooded fully;
(4) room temperature (20-25 ℃) was solidified 20-30 minute;
(5) pull out plastic pattern, prune profile;
(6) the super hard gypsum powder is pressed gouache ratio: 7ml: 30g slowly adds gesso in rubber cup and is modulated into paste in the tap water;
(7) this paste is poured in the alveolar bone die, the limit is with the vibration of paste limit, to remove the bubble in the paste, in order to avoid influence mold surface form and quality;
(8) room temperature (20-25 ℃) was solidified 6-30 minute down, and general set time in summer is short, and set time in winter is long;
When (9) treating that the model surface temperature is reduced to room temperature (20-25 ℃) plaster cast is pulled out;
(10) aeration-drying place is preserved under the room temperature.
The present invention compares with existing material, has following advantage and effect: color, hardness are similar to people's alveolar bone; Cheap, be easy to apply; Processing technology is easy, does not need special process equipment; Plasticity is good, can embody local trickle metamorphosis; But long preservation is indeformable; The recyclable processing of discarded object is beneficial to environmental protection.
Embodiment
(1) makes the alveolar bone silicone rubber impression
1. alveolar bone rigid plastic model is fixed in model box base central authorities;
2. will answer mould with silicon rubber A, B component by 1: 1 mass ratio mixing 50 or 55 or 60 seconds on de-airing mixer;
3. on bobbing machine with in the slow injection model box of silicon rubber, until the rigid plastic model is flooded fully;
4. solidified under the room temperature 30 minutes;
5. pull out plastic pattern, prune profile.
(2) make super hard gypsum alveolar bone model
1. the super hard gypsum powder is pressed gouache ratio: 7ml: 30g slowly adds powder in rubber cup and is modulated into paste in the tap water;
2. this paste is poured in the alveolar bone die of making by certain form and requirement, the limit is with the vibration of paste limit, to remove the bubble in the paste, in order to avoid influence mold surface form and quality;
3. solidified 30 minutes under the room temperature, general set time in summer is short, and set time in winter is long;
When treating 4. that the model surface temperature is reduced to room temperature (20-25 ℃) plaster cast is pulled out;
5. aeration-drying place is preserved under the room temperature.
