Description

Experimental provision and manufacture method in a kind of Dental plaque biofilm mouth

Technical field

The invention belongs to medical experiment device field, particularly relate to experimental provision and manufacture method in a kind of Dental plaque biofilm mouth.

Background technology

In the etiology and therapeutics research of oral diseases or bacterial plaque disease, in mouth, experiment is in occupation of consequence.Use mouth inner model effectively can build dental plaque biology in the specimen needing test.Enamel, dentin, dental materials etc. can be placed as specimen growth biomembrane in biological film model.Utilize mouth inner model can the cause of disease of effective study of disease and various protective agents and measure, such as various anticarious tooth paste, collutory, anticariogenic agent etc.

In desirable mouth, biological film model needs to reach following ask for something:

Simple for production, standardization: the unification being conducive to the more experiment of sample and baseline;

Subject wears's foreign body sensation is little, comfort level good, safety is good, is conducive to improving experimenter's fitness;

Material biological safety is good;

Need enough spaces and position placement specimen, in experimentation, pick and place specimen conveniently.

Current biological film model also fails to reach above requirement completely.

Summary of the invention

The object of the present invention is to provide experimental provision in a kind of Dental plaque biofilm mouth, be intended to solve that complex manufacturing technology that biological film model in existing mouth exists, comfort level are poor, poor stability, awkward problem.

The present invention is achieved in that experimental provision in a kind of Dental plaque biofilm mouth, and in described Dental plaque biofilm mouth, experimental provision is the maxillodental resin mould of experimenter; It is foursquare projection that jaw bow position in model both sides is provided with transverse section, and each projection is provided with circular hole; 3 square protrusions at He Gong position, model both sides form sample slot along jaw bow longitudinal arrangement; Sample is positioned in sample slot, uses silicone rubber to fix.

Further, the jaw bow position in model both sides respectively has 3 transverse section to be foursquare projection.

Further, each projection there is the hole that 6 circular.

The manufacture method of experimental provision in a kind of Dental plaque biofilm mouth of the present invention, is characterized in that, comprise the following steps:

Step one, using experimenter's maxillary teeth as object impression taking, makes die;

Step 2, with the die made in gypsum perfused step one, obtains the plaster model of the maxillary teeth of experimenter;

Step 3, plaster model places 6 standard aluminum molding blocks, and each aluminum module transverse section is the square of length of side 5mm, and Modular surface 6 of being evenly distributed are diameter and the column type projection being highly 1mm; The aluminum module of 6 standards is divided into two rows, is bonded in the position of the palatine arches of plaster model with glass ionomer cements;

Step 4, is placed on press by the plaster model with aluminum standard block, compacting model; The position being bonded with standard aluminum clamp dog can form the sample slot of projection, as the space that specimen is placed; Column type on standard aluminum clamp dog can form again 6 little projections, using the position as perforate;

Step 5, uses polishing sand paper to grind off 6 kicks formed in step 4, and each sample slot surface forms the hole of 6 diameters at 1mm, and Sample diameter, generally at about 4mm, is placed in sample slot and should not drops to oral cavity; Hole is conducive to communicating with oral environment, can be conducive to simulating oral cavity environment, forms Dental plaque biofilm;

Step 6, is positioned over sample in sample slot, uses silicone rubber to fix, and silicone rubber wears plasticity after in experimenter's mouth near a fixed sample groove of sample slot, another side.

The present invention can provide a mouthful inner model for needing the experiment building Dental plaque biofilm in mouth, relative to existing technology, has the advantage of the following aspects:

1, modelling is easy, manufacturing process standard criterion, and subject wears's model has personalization;

2, model wears that sense of discomfort is little, foreign body sensation is little, aesthetic property is good, does not affect daily life, talk;

3, the placement location of specimen is at palatine arches, and specimen placement space is comparatively large, and specimen places safety, and patient's sense of discomfort is little;

4, model weight very light, get and wear conveniently; Specimen picks and places conveniently, and maintenance is better, and safety is high;

What 5, modeling material was selected is the invisible orthotic device of correction employing and the material of keeper, and coordinate silicone rubber impression material, material is light, biological safety good.
