Description

A kind of dental sample model

Technical field

The present invention relates to a kind of dental sample model and preparation method thereof.

Background technology

Dental sample model has had a change repeatedly so far from invention, develops into use industrial plastic analogue formation from initial with the Gypsum Fibrosum analogue formation, arrives now removable instance model on the market again.These changes on quality have brought nonabradable benefit, but have lost advantage originally sometimes on the contrary, illustrate comparison below, and are clear in the hope of more:

1) dental sample model of Gypsum Fibrosum material: it is that consumer's consciousness comes back in the early stage, and under the situation that the market competition becomes more fierce, Producer is for promoting product, the instance model of being done.Production method: selecting in the model of promptly fetching from dentist becomes instance model behind the tooth form model copy more attractive in appearance.Its advantage is that the tooth external form is very the same with natural teeth, but its fatal defective is easy abrasion, breaks, is prone to dirty and be difficult to find the tooth position complete in being referred to as model.

2) dental sample model of industrial plastic: it is to make a substandard tooth appearance earlier, and the complete and symmetric model in tooth position is used the silica gel duplicating model, and the use industrial plastic is irritated mould and made.This model is very dark and fall recessed greatly because of emulated tooth occlusal surface developmental groove, as easy as rolling off a logly damages silica gel.So maker is to let life-span of silica gel mould just be able to increase sting slick and sly that head repaiies to the profile of model tooth, the occlusal surface developmental groove is also done very shallowly, and is not recessed, like this, can let the life-span of silica gel model improve greatly.But above-mentioned way has but reduced the instance model simulated effect greatly.On the whole, this kind class model is difficult for damaging, is difficult for dirty, but the non-constant of outward appearance.

3) removable dental sample model: this instance model also is to adopt industrial plastics to make, and tooth contour is the same with second kind.Difference is that it partly works it out the root of the tooth of every tooth, and all teeth can be got, and independence is stronger.This class model has new meaning but the design imperfection, and model and tooth all adopt rigid plastics, very easily get loose to wear shakiness, and also be easier to get loose and break, be the improved technique direction of the present invention based on above problem.

Existing dental sample model is made up of the mold portion branch of tooth and hard independently, and the defective of its design is aspect tooth.Produce for ease and reduce cost, maker has changed the natural former state of tooth, promptly makes slyness into stinging a point, fills and leads up developmental groove, has lost the graceful originally external form of tooth.

The model part of existing dental sample model adopts the hard industrial plastic to process the position that combines with tooth.Because of tooth and model part hard material all, so tooth and mold portion can not adopt effective mechanical bond, as long as chucking slightly; Glass as two circles is built together, and access times are many, time long back easy abrasion fluffs, and turn around by model part; Tooth just falls completely, and is extremely undesirable.

Further, be provided with convex-concave maintenance draw-in groove in the tooth hole on the said model internal layer, and the corresponding place of the root of the tooth of tooth is provided with the convex-concave maintenance draw-in groove of coupling.The deep and firm more position of said draw-in groove effect is good more, and maintenance power can strengthen along with increasing of draw-in groove number; Tooth can play good maintenance effect after inserting the tooth hole, and colliding with also is difficult for falling tooth.

Further, said convex-concave maintenance draw-in groove height is greater than 1 millimeter.

For solving above-mentioned second technical problem, the manufacture method of a kind of dental sample model of the present invention comprises the steps:

1) making of tooth

1. select a cover and the prefabricated close model of sample mold of doing earlier;

2. mend the mould plaster of choosing greatly to the tooth mould, to the size of enough carving;

3. go up interlock, also mend big enough engravings to tooth and model that pattern is not up to standard with Gypsum Fibrosum,

4. the technician follows according to the anatomic form of tooth and dental bed and carves, to similar and symmetrical with natural tooth;

5. carve good back with the multiple mould of silica gel, make a set of model, on multiple mould, cut apart, cut the vertical gang mould type of all teeth together, and parallel, can not hurt the two adjacent surfaces of tooth;

6. the technician partly carves the tooth of cutting apart to root of the tooth according to anatomic form again, and at this moment, tooth promptly accomplishes;

2) making of model part

1. duplicate a cover carving good tooth with silica gel, make (then tooth and model compare easy separation) with softer Gypsum Fibrosum;

2. be applied to the tooth that duplicates in the for the first time multiple silica gel mould; Gypsum Fibrosum with harder irritates The model out;
