Abstract

The utility model discloses a basic mode, which can be used for common users by themselves to make a tooth mode without special appliance during the mode-forming process. The utility model comprises a cambium made of low temperature thermoplastic material, and a propping layer is arranged on the surface or in the cambium. The propping layer can support the cambium between 45 Deg C and 100 Deg C and deform thermoplastic into a chip with the cambium. The cambium of the basic mode has thermo plasticity at certain temperatures. During the thermoplastic tooth mode-forming process, the propping layer on the surface remains the matching shape with tooth radian on upper jaw or lower jaw, and deformation and conglutination are avoided. The mode is made in the mouth directly without the special appliance, therefore, the dentistry doctors or common users can make the tooth mode conveniently, and the cost of the customers during the tooth mode-making process is reduced.

Description

A kind of basic mode that is used to make the tooth mould

Technical field

This utility model relates to a kind of basic mode that is used to make the tooth mould, is applicable to the rapid shaping of Buccodental model.

Technical background

At present, the making of tooth mould normally utilizes one-tenth mold materialss such as alginate or silicones to obtain the tooth mould that is used for prefabricated artificial tooth in the oral cavity, this process need be finished by means of the utensil of special use by surgeon dentist or professional people usually, because its complex procedures, so price is also relatively more expensive.Disclose a kind of fixing material for surgery among the patent CN99117171.3 of my application, this kind material has certain mechanical strength at normal temperatures, has certain plasticity under the plastotype temperature.Utilize this shape-memory properties, also can be used as the one-tenth mold materials of tooth mould with it, the length that this material is made approximates into the lamellar basic mode that mould tooth beam overall, width approximate twice tooth height, after in hot water, making it softening, be coated on the tooth, after treating its solidifying and setting, in the oral cavity, take out, promptly form the tooth mould.But also just because the low-temperature thermoplastic that this material has, after this basic mode was softening, the operator was difficult to keep its original shape and size, and distortion or be pasted together under external force easily is stretched, cause operating difficulties, common user also is difficult to easily by oneself making the tooth mould.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of in operating process, the basic mode that is used to make the tooth mould that can keep its original shape and size, become in the mold process, need not be convenient to common user easily by oneself making the tooth mould by the utensil of special use.

The technical solution of the utility model is: a kind of basic mode that is used to make the tooth mould, comprise the film forming layer of making by low-temp thermoplastic material, and it is characterized in that: described film forming layer surface and/or inside are provided with supporting layer.

Especially, described supporting layer also can be with the thin slice of film forming layer plastic deformation for can support film forming layer in 45 to 100 temperature ranges Celsius.Wherein optimum temperature is 60 to 80 degrees centigrade.

Specifically, described supporting layer is a metal forming, or the nonmetallic slices suitable with its performance, is covered in the upper surface or the lower surface of film forming layer.

As further improvement of the utility model, described film forming layer is the curved body that matches with the upper jaw or mandibular teeth gabarit radian, and supporting layer is suitable with the film forming layer geomery.

Further improve as of the present utility model, the longitudinal cross-section of described curved body is " V " shape, and supporting layer is covered in the lower surface of " V " shape curved body.

In the technical program, described metal forming can be aluminium foil or Copper Foil or tinfoil paper.

In the technical solution of the utility model, the film forming layer of basic mode has thermoplasticity at a certain temperature, in the process of molding gear mould, be subjected to thermal softening, because its surface is provided with supporting layer, can keep its original " V " shape curved body shape that matches with the upper jaw or mandibular teeth gabarit radian, avoid its distortion and adhesion, need be by the utensil of special use, just can directly in the oral cavity, make, like this, surgeon dentist or common user all can be made the tooth mould easily, reduce the cost of consumer in making the tooth mold process.

Description of drawings

Below in conjunction with drawings and Examples the basic mode that this utility model is used to make the tooth mould is described further.

Fig. 1 is the axonometric chart of this utility model basic mode;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Shown in accompanying drawing 1,2, this basic mode that is used to make the tooth mould, the film forming layer 1 and the supporting layer 2 that is covered in its lower surface that comprise V-shaped curved body, the radian of curved body and the upper jaw or mandibular teeth gabarit radian roughly coincide, the consistent size of the size of supporting layer 2 and film forming layer 1 or be slightly less than the size of film forming layer 11 keeps the geomery of film forming layer 1 to be as the criterion under low temperature thermoplastic condition playing.Supporting layer 2 is made by aluminium foil, also can be Copper Foil or tinfoil paper or the material similar to its performance, as some producing high-molecular condensation material, is characterized in that itself has certain rigid, has good plasticity under the effect of slight external force.And film forming layer 1 can adopt disclosed among the CN99117171.3 is that the cold plasticity material of main component is made with the using trans-polyisoprene, utilizes this material to have certain mechanical strength at normal temperatures, have the film forming layer 1 that good plastic characteristics are made basic mode under 45-100 degree temperature Celsius.Basic mode is put into about 65 degrees centigrade hot water, treat film forming layer 1 become fully transparent after, take out, hold basic mode " V " shape lower surface supporting layer 2, the inner surface of " V " shape film forming layer 1 is fitted on the tooth, press...with one's finger and press supporting layer 2 surfaces, film forming layer 1 and tooth gabarit are fitted fully, treat just to form the tooth mould that fits like a glove with tooth after film forming layer 1 sclerosis.Wherein supporting layer 2 can not only keep film forming layer 1 original shape and size in film forming layer 1 softening back, and, in the process of molding gear mould, avoid finger and film forming layer 2 adhesions, make surgeon dentist, or even common user all can be made the tooth mould easily.

The supporting layer of this utility model basic mode not office also can be arranged on the inside of film forming layer or is clipped between two film forming layers in the outer surface that is arranged on film forming layer, all belongs to the equivalent variations of technical solutions of the utility model.And supporting layer also is not limited to metal forming, and all can support the technique effect that film forming layer also can all can be realized the technical program with the material of film forming layer plastic deformation in the moulding temperature range of film forming layer.
