Thermoplastic material is a material that can flow and deform when heated and can maintain a certain shape after cooling, and the thermoplastic material has the performance of repeatedly heating, softening and cooling to harden in a certain temperature range, such as polyethylene plastic and polyvinyl chloride plastic.
The tooth model 13 and the alveolar bone model 11 of the application are connected through the connecting film 12 made of the thermoplastic material, when the connecting film 12 is softened in a heating state, the tooth model 13 can move on the connecting film 12, and then the tooth model 1 can be adjusted in a mode of finely adjusting the tooth model 13 or replacing part of the tooth model 1 in the heating state, so that the adjusted tooth model 1 is suitable for forming of an orthosis in a subsequent corresponding treatment course, and further the tooth model 1 can be repeatedly used for multiple times without manufacturing a plurality of tooth models according to the orthopedic treatment course, and time and material cost are effectively saved.
Specifically, the alveolar bone model 11 has a U-shaped configuration and has a first end 111 and a second end 112, and the first end 111 and the second end 112 are oppositely disposed. The connection film 12 is provided on a part of the surface of the first end portion 111, and the root of the tooth of the dental model 13 is connected to the connection film 12. The present application connects a tooth model 13 with an alveolar bone model 11 through a connection membrane 12. When the connecting film 12 is in a heat-softened state, the relative position between the tooth model 13 and the alveolar bone model 11 can be changed, and at this time, the orientation of the moving tooth model 13 can be adjusted on the connecting film 12, thereby adjusting the relative position and relative angle between the tooth model 13 and the alveolar bone model 11. When the connecting film 12 is solidified in a cooling state, the tooth model 13 and the alveolar bone model 11 are fixedly connected through the connecting film 12, so that the dental model 1 can be modified by moving and adjusting the orientation of the tooth model 13 arranged on the connecting film 12 in a heating state, and the dental model can be rapidly cooled after the adjustment is completed.
Further, the first end portion 111 is provided with a plurality of recesses 113, the plurality of recesses 113 are sequentially arranged along the longitudinal direction of the alveolar bone model 11, and the shape and size of the recesses 113 are set to correspond to the shape and size of the tooth root of the dental model 13. The connection film 12 is provided on the inner surface of each recess 113. The plurality of tooth models 13 are provided, and the roots of the teeth of the plurality of tooth models 13 are respectively provided in the concave portions 113 and connected to the connection film 12. This application is through the setting of concave part 113 to carry on spacingly to tooth model 13, make tooth model 13 and alveolar bone model 11 connect more stably when using.
It can be understood that as a dental mold, the alveolar bone model 11 and the dental model 13 do not need to be identical to the alveolar bone and teeth in the real oral cavity, i.e., the root of the tooth model 13 does not need to go deep enough into the alveolar bone model 11, and therefore, the concave portion 113 of the alveolar bone model 11 does not need to be designed too deep, and the root of the tooth model 13 does not need to be designed too long, as long as the concave portion 113 of the alveolar bone model 11 can be fitted with the root of the tooth model 13 to achieve a simple limit action.
In the embodiment, the thickness of the connecting film 12 is D, and D is more than or equal to 0.5mm and less than or equal to 2 mm. This application will be connected the thickness of membrane 12 between 0.5mm-2mm for the thickness size of connecting membrane 12 is just in time moderate, because, the connection membrane 12 in this application need not to establish too thickly, only need can make tooth model 13 move on connecting membrane 12 under the heating state, makes tooth model 13 can be through connecting membrane 12 and alveolar bone model 11 fixed connection under the cooling state can.
Further, the tooth model 13 and the alveolar bone model 11 are respectively made of a hard material, and the alveolar bone model 11, the connection membrane 12 and the tooth model 13 are integrally printed and molded. Among them, the type of the hard material is different depending on the curing (changing the material from a liquid state to a solid state), and for example, when a three-dimensional object is formed by ultraviolet light curing, the hard material may be a light-curable resin material. In the present embodiment, the hard material refers to a material with a high hardness after being cured by a curing device, and specifically, the hard material may be a material with a hardness higher than 70A, and preferably a material with a hardness of 70-90A; for example, the hard material may be a material including, by weight, 5 to 50% of a vinyl oligomer, 50 to 95% of a vinyl monomer, 0.5 to 10% of a photoinitiator, 0 to 0.5% of a colorant, and 0.05 to 8% of an additive. It is understood that the hard material in this embodiment may be a single hard material, or may be a mixture of multiple materials that is hard. In order to ensure that the tooth model 13 and the alveolar bone model 11 are not softened by heating when the connecting membrane 12 is softened by heating, it is only necessary to ensure that the melting temperature of the hard material used to make the tooth model 13 and the alveolar bone model 11 is higher than the melting temperature of the connecting membrane 12 regardless of which hard material is.
The utility model provides a dental model 1 is by alveolar bone model 11, connection membrane 12 and the integrative shaping of printing of tooth model 13, and then can avoid the error that produces when each position passes through mechanical assembly in dental model 1 to relative position relation between each position is close the true condition in patient's oral cavity more in can guaranteeing dental model 1.
Referring to fig. 3, fig. 3 is a perspective view of a dental mold according to an embodiment of the present disclosure. The tooth mould also comprises a base 2, the base 2 is used for fixedly placing a dental model 1, and the dental model 1 is detachably connected to the base 2. This application is through the setting of base 2 to make things convenient for the storage of dental cast 1, and the health.
Specifically, the base 2 has a first surface 21, the first surface 21 is provided with a limiting groove 211, and the shape and size of the limiting groove 211 are matched with the shape and size of the alveolar bone model 11. The second end 112 of the alveolar bone model 11 is connected to the limit groove 211 in a clearance fit (clearance fit means fit with a gap) manner, so that the dental cast 1 and the limit groove 211 can move relatively after being matched, and the alveolar bone model is convenient to detach and beneficial to compensating various errors.
In this embodiment, the second end 112 of the alveolar bone model 11 is connected to the stopper groove 211 in a clearance fit manner.
