Description
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, in the hope of more clear:
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: promptly selecting in the model of 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 be easy wearing and tearing, break, easily dirty and be difficult to find the tooth position complete to being referred to as model.
2) dental sample model of industrial plastic: it is to make a substandard tooth sample 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 log silica gel is damaged.So maker is to allow life-span of silica gel mould just be increased the profile of model tooth is stung slick and sly that head repaiies, the occlusal surface developmental groove is also done very shallowly, and is not recessed, like this, can allow 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 convenience and reduce cost, maker has changed the natural former state of tooth, promptly makes slyness into stinging a point, and developmental groove is filled and led up, and has lost the graceful originally external form of tooth.
The model part of existing dental sample model adopts the hard industrial plastic to make 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, wear and tear easily in long back of time fluffs, and turns around by model part, tooth just falls completely, and is extremely undesirable.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of dental sample model.That this model has is not fragile, it is dirty to be difficult for, tooth is worn and just can be played good maintenance effect on the model, can be when not using external force, and tooth can not come off, and has improved the deficiency of old style instance model, makes dental sample model more perfect.
Another technical problem that the present invention will solve provides a kind of manufacture method of dental sample model.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: it comprises tooth and model part, and described model part comprises model skin, model internal layer and model base; The outer coupling of described model wraps the model internal layer, and is provided with the tooth hole of settling tooth on model skin and model internal layer, and described tooth is inserted in the tooth hole; Described model base wraps the edge of model skin and model internal layer.
Further, the outer material that adopts hard of described model is to possess wear-resistant function attractive in appearance; Described model internal layer adopts the soft plastic with high resiliency, high reminiscence; Described model base adopts hard material, and can wrap the inside and outside layer of model, and having has wear-resistant and be difficult for functions such as dirty, forms complete modelling.
Further, described model base adopts ABS plastic, PC (Merlon) or PP (polypropylene) material; Outer PVC (polrvinyl chloride), PE (polyethylene) or PU (polyurethane) material of adopting of described model; Described model internal layer adopts rubber or silica gel material; Described tooth adopts resin, PU (polyurethane) or glass material.
Further, be provided with convex-concave maintenance draw-in groove in the tooth hole on the described 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 described 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, described 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 pre-close model of sample mold of making earlier;
2. the mould plaster of choosing is mended the tooth mould greatly, to the size of enough carving;
3. go up interlock, tooth and model that pattern is not up to standard also mended big enough engravings with Gypsum Fibrosum,
4. the technician follows according to the anatomic form of tooth and dental bed and carves, to similar and symmetrical to natural tooth;
5. carve good back with the multiple mould of silica gel, make a set of model, on multiple mould, cut apart, the vertical gang mould type of all teeth is cut 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 is easier to separate with the model ratio) with softer Gypsum Fibrosum;
2. the tooth that duplicates is applied in for the first time multiple silica gel mould; With harder Gypsum Fibrosum whole model is irritated out;
3. again the tooth than soft gypsum on the model is dug out, can obtain the model that matches with tooth;
3) production method of described model internal layer
1. the silica gel that duplicates of tooth is recorded a cover with anhydrite, at the suitable groove of place mill of the labial surface of all roots of the tooth, the tongue side is also ground a groove by top, a Lower Half mill maintenance plane;
2. the better tooth of mill is applied in first silica gel model that duplicates by the tooth position, wears firm; The resilient plastics of reuse are irritated into;
3. after treating that glue is hard, can obtain a soft model that coincide with the tooth draw-in groove.
4) various piece is fitted together, both got the inventive method products obtained therefrom.
That the present invention has is not fragile, it is dirty to be difficult for, tooth is worn and just can be played good maintenance effect on the model, can be when not using external force, and tooth can not come off, and has improved the deficiency of old style instance model, makes dental sample model more perfect.
