Abstract
The invention relates to a preparation method of an oral impression material, and belongs to the technical field of preparation of oral impression materials. In allusion to the problems that the oral impression material prepared with the conventional preparation method has poor antibacterial performance, and soaking disinfection may change impression weight and surface roughness and cause dissolution of a surfactant contained in the impression material, resulting in significant reduction in wettability of the impression after disinfection, the invention provides the preparation method of the oral impression material, which comprises the following steps: cutting bitter gourd leaves, extracting and collecting antibacterial proteins, modifying an inorganic filler by the antibacterial proteins, and compounding. The oral impression material prepared with the preparation method provided by the invention has the antibacterial efficiency as high as 99.5%; meanwhile, the contact angle is 65%, so that the wettability of the oral impression material is effectively improved; the preparation process is simple; the antibacterial oral impression material is prepared from the bitter gourd leaves, so that the oral impression material is green, safe and pollution-free.
Description
Technical field
The present invention relates to a kind of preparation method of oral cavity impression material, belong to oral cavity impression material preparing technical field.
Background technology
Die is the former of object, and buccal impression is the former of oral cavity related organization, takes the material adopting during seal carving mould to claim
For moulage.In clinical position, accurate die to be obtained, except the qualification with doctor's operating technology has outside the Pass, also
Relevant with the selection of moulage.In the selection of material, need the species to moulage, feature, composition, performance, application
Scope is made sufficiently to understand, so could be required according to different reparations, select corresponding moulage, makes to take the die of system accurate
Really reflect the situation of oral cavity related organization.The operation first taking system, being in oral restoration work of buccal impression, its quality is straight
Connect and be related to final repairing effect.
Since eighties of last century fifties, the advantage that room temperature vulcanized silicone rubber is used as oral cavity impression material is recognized it by people
Afterwards, room temperature vulcanized silicone rubber has just obtained fast development in oral cavity impression material field.Silicon rubber in developed country at present
Moulage has become a kind of clinical essential moulage, although vps moulage is considered to connect most at present by many scholars
The oral cavity impression material that closely " preferable " requires, but in its application process, but there is a problem of that one is made us perplexing: due to oral cavity
Often with the presence of pathogenic microorganism in environment, and silicone rubber impression material is stronger to the adsorption capacity of microorganism, and in silicon rubber certain
A little compositions possibly even become the culture medium of growth of microorganism, therefore when die transmits between patient, medical personnel and skilled worker
When, easily cause pathogenic microorganism cross-infection.The disinfectant that vps moulage is commonly used includes sodium hypochlorite solution, iodoform, benzene
Phenol, glutaraldehyde etc..These disinfectants the dimensional accuracy of die is affected less, but, soaking disinfection may cause die weight,
The change of surface roughness, causes the surfactant dissolution contained by moulage, thus causing wetability after impression disinfection bright
Aobvious decline, so it is stronger prepare a kind of antibiotic property, necessary on the scantling less material of impact.
Content of the invention
The technical problem to be solved: the oral cavity impression material antibiotic property for existing preparation is poor, and immersion disappears
Poison may cause the change of die weight, surface roughness, causes the surfactant dissolution contained by moulage, thus causing
The problem that after impression disinfection, wetability is decreased obviously, there is provided one kind is by being cut momordica charantic leaf and being extracted collection antibacterial
Albumen, is modified to inorganic filler by antibacterial protein, is combined the method preparing oral cavity impression material simultaneously, efficiently solves
Material anti-microbial property is poor, and soaking disinfection leads to the defect that material wetability declines.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) collect fresh bitter blade, be divided into the momordica charantic leaf strip of 0.5cm length along vein, subsequently 1:5 in mass ratio, by hardship

Modified filler, 20～25 parts of vinyl mq silicones be placed in kneader, stirring mixing 25～30min after, 155～160
2～3h is dried at DEG C, is prepared into base resin material；
(5) count by weight, choose the base resin material of 45～50 parts of above-mentioned preparations, 5～10 parts of containing hydrogen silicone oils, 0.1～
0.5 part of polyoxyethylene aliphatic alcohol ether and 0.1～0.2 part of dimethyl polysiloxane are placed in beaker, be stirred at room temperature mixing 1～
2h, subsequently after standing 6～8h, collects compound and uses 300 mesh screen, the slurry after collection filtration, still aging 6～8h,
A kind of oral cavity impression material can be prepared into.
The oral cavity impression material tensile strength of present invention preparation is 2.5～3.0mpa, tearing strength is 4.5kn/m, contact
Angle, up to 65 °, is effectively improved the wetability of material, simultaneously after the oral cavity impression material using present invention preparation, with material
The no abnormal response such as hyperemia, bleeding, erosion, ulcer of the mucous membrane at position, antibiotic rate is up to 99.5%.
Compared with additive method, Advantageous Effects are the present invention:
