Description
Technical Field
The utility model relates to the field of dental teaching, in particular to an oral cavity training model component capable of expanding anatomic structure functions.
Background
In the training courses of the stomatology institutions and on training classes held by the stomatology instrument companies, the physical oral training models are needed, and because the simulated operation of the training models is destructive, the models are all disposable, so that model plug-ins appear, namely, a complete full-mouth model is taken as a base, and small model plug-ins are installed on the model plug-ins, and the training operation is only aimed at the model plug-ins, so that the cost of the training can be reduced.
However, because of too many oral clinical operation types and various user demands, the model plug-ins are also various, each plug-in can only deal with one clinical operation, so that the model plug-ins are produced by adopting low-efficiency and low-precision production processes such as small batch, manual production and the like, even the small model plug-ins are high in manufacturing cost, and the delivery period is relatively long.
For example, in the field of stomatology teaching, the incision and suturing range is mainly aimed at incision and suturing of soft tissues (gingiva or mucosa) in the oral cavity, in the current market, an incision and suturing model training model insert for the incision and suturing training is made of thermoplastic materials, a hard structure is molded by injection, an oral bone is simulated, the surface of the simulated oral bone is simulated by multiple layers, soft rubber and sponge are overlapped to simulate the skin, the training model insert can only perform single incision and suturing training operation, other oral training operations cannot be performed, and cutting scraps of the oral bone structure prepared from thermoplastic materials can be drawn very long and even melt and adhere to a cutting drill, so that training interruption is greatly different from practical operation, and the training effect of students is influenced.
In the actual oral treatment operation, not only is the incision suture operation performed, but also other oral treatment operations such as oral implant, oral restoration and the like are performed, when students perform oral surgery training operation at present, the students are influenced by the single function of the oral surgery training model plug-in, only the oral surgery operation is decomposed, and one oral surgery training operation is completed through a plurality of different oral surgery training model plug-ins. Students can only train on single skills using the model plug-in with single functions, rather than systematically training skills on the whole surgical operation process by starting with incision stitching. The practical training operation training of students is greatly different from the actual oral surgical operation, which is not beneficial to improving the practical skill of the students.
Therefore, how to make the oral training model plug-in have more training functions, so that the oral training model plug-in can meet the practical training requirement of students on surgical operation system, and the oral training model plug-in becomes an urgent problem to be solved in oral training courses.

The top surface of the simulated cortical bone 21 is coated with a pre-bonding treatment agent.
In different practical training, the gingival flap surgery has different requirements on the bonding strength of the gingiva and the cortical bone, and different bonding pretreatment agents can be adopted according to the practical training requirements, so that the bonding strength of the cortical bone and the gingiva can be adjusted.
The simulated gingiva 22 is fixedly compounded with a simulated periosteum 23 towards one side of the simulated cortical bone 21, the simulated periosteum 23 is made of soft rubber with hardness and toughness both greater than those of the simulated gingiva 22, and the thickness of the simulated periosteum 23 is smaller than that of the simulated gingiva 22. By adding the simulated periosteum 23 before encapsulating the simulated gingiva 22, the hand feeling and the anatomical shape are more vivid when cutting, turning over, reducing and sewing the gingiva, the simulated periosteum 23 is made of soft rubber materials of the same type as the simulated gingiva 22 by injecting glue, however, the soft rubber materials used by the simulated periosteum 23 are required to be higher in hardness and better in toughness than soft rubber materials used for forming the simulated gingiva 22, the thickness of the simulated periosteum 23 is thinner, generally about 0.3mm, and the multifunctional plug-in unit 2 with the simulated cortical bone 21, the simulated periosteum 23 and the simulated gingiva 22, namely a "cutting and sewing training model plug-in unit", can develop training courses such as gingival cutting, turning over, reducing and sewing.
A filling cavity 211 is formed inside the simulated cortical bone 21, and the filling cavity 211 is filled with a simulated cancellous bone 24 prepared from a soft material. A filling cavity 211 is formed in the simulated cortical bone 21, and a relatively soft simulated cancellous bone 24 is filled in the filling cavity 211. When the model is adopted to carry out practical training of oral implant surgery, the hand feeling of the drill bit falling off when the drill bit breaks through from hard cortical bone and drills into cancellous bone can be simulated, and the hand feeling of the torque in the process of entering into cancellous bone is changed from tightening to loosening when implant is implanted by simulating tapping and tapping implant nails at the holes on the surface of cortical bone.
The bottom surface of emulation cortex 21 is last to be formed with the filling opening that communicates with filling cavity 211, the interval is equipped with two at least screw holes 212 on the emulation cortex 21 bottom surface, each screw hole 212 evenly distributed is in filling the opening periphery, be equipped with two at least via holes 12 on the plug-in components positioning slot 11 bottom surface on the full mouth mandibular model 1, via holes 12 and screw holes 212 on the emulation cortex 21 bottom surface are just to setting one by one, wear to be equipped with screw 3 in the via holes 12, screw 3 can with the screw hole 212 threaded connection on the emulation cortex 21 bottom surface. The threaded holes 212 are distributed on both sides of the filling opening of the simulated cortical bone 21 instead of one screw 3 hole in the center, thus allowing room for the subsequent increase in the structure required for the oral implant procedure.
The artificial mandibular duct 25 is also provided with a hollow artificial mandibular duct 25, the artificial mandibular duct 25 is filled with artificial blood or red silica gel, openings at two ends of the artificial mandibular duct 25 are closed, two ends of the artificial mandibular duct 25 are fixedly connected with the inner side wall of the filling cavity 211 of the artificial bone cortex 21, and the artificial mandibular duct 25 is buried in the artificial bone cancellous 24.
As an insert for a mandibular model, there is a bony canal, a mandibular canal, clinically in the mandible of the posterior dental area, in which there are inferior alveolar arteries, veins, nerves. According to the application, the hollow simulated mandibular duct 25 is designed, the simulated mandibular duct 25 is internally sealed with simulated blood or red silica gel to simulate blood vessels, and when the simulated mandibular duct 25 is damaged during the implant operation training, red liquid or substances are carried out, so that the simulation degree of the training can be improved. As shown in fig. 13, if the student does not implant the implant nail at a site or selects the implant nail 4 to have a too long length, the simulated mandibular duct 25 is destroyed, and a medical accident is simulated. If the implant nail is placed on the pointed position, the cortex surface of the alveolar bone at the position is very close to the mandibular canal, and even the shortest implant nail is not used, a teacher can develop a higher-order practical training course of implant bone implantation on the model plug-in unit.
A process for producing an oral cavity training model component capable of expanding anatomical functions, comprising the steps of:
Step one: the method comprises the steps of manufacturing a full-mouth mandible model 1, forming at least one plug-in locating slot 11 on the mandible model, processing a through hole 12 on the bottom surface of the plug-in locating slot 11, wherein the full-mouth mandible model 1 can be manufactured by 3d printing, silica gel mold casting or metal mold injection molding, the manufacturing method is generally determined according to the requirement of a user, and the full-mouth mandible model 1 is not a consumable product in practical training, so the requirement is generally not too great, but is required to be durable, the best silica gel mold casting is adopted, and the best used material is polyurethane or epoxy resin. If the demand is small but delivery is urgent, the printing production can be carried out in 3 d. If the demand is large, the metal mold can be opened for injection molding production, and the material can be common thermoplastics with better dimensional stability such as ABS, HIPS, PC and the like only for the supporting structural member in practical training;
step two: manufacturing a multifunctional plug-in 2:
(1) The simulated bone cortex 21 is made of hard materials, the simulated bone cortex 21 is optimally selected from modified thermosetting plastics for injection molding, a filling cavity 211 with an opening is integrally formed on the bottom surface of the simulated bone cortex 21 during molding, because the simulated bone cortex 21 is the most basic part, a mass production process of opening a metal mold and injection molding by an injection molding machine is optimally adopted, then a nut 2121 or a tapping screw is embedded on the bottom surface of the simulated bone cortex 21, the embedded nut 2121 is embedded in the molding mold to be integrally molded with the simulated bone cortex, the tapping screw is performed after the simulated bone cortex is taken out of the mold, the embedded nut 2121 or the tapping screw can form a threaded hole 212 at the bottom of the simulated bone cortex 21 according to the requirement of practical training, and then the pre-bonding treatment agents with different bonding strengths are selected according to the requirement of practical training and are coated on the top surface of the simulated bone cortex 21;
(2) The simulated bone cortex 21 is put into an encapsulation mold, a simulated bone film 23 is formed on the top end surface of the simulated bone cortex 21, the formation mode is that liquid silica gel (LSR) or thermoplastic elastomer (TPE) is injected into the encapsulation mold through an injection molding machine, the simulated bone film 23 can be formed through a liquid silica gel (LSR) coating process, then simulated gum 22 is formed on the surface of the simulated bone film 23 through the injection molding machine in a mode that the liquid silica gel (LSR) or the thermoplastic elastomer (TPE) is injected into the encapsulation mold, the edge of the simulated gum 22 is stopped at the flange of the bone cortex by utilizing the encapsulation mold, the hardness and toughness of the liquid silica gel (LSR) or the thermoplastic elastomer (TPE) used for forming the simulated bone film 23 are higher than those of the simulated gum 22, and the thickness of the simulated bone film 23 formed on the top end surface of the simulated bone cortex 21 is smaller than that of the simulated gum 22;
(3) The simulated bone cancellous 24 of the simulated bone cancellous material is filled in the filling cavity 211 of the simulated bone cortex 21, when the multifunctional plug-in 2 is positioned in the posterior tooth area, the simulated mandibular duct 25 of the simulated mandibular duct is manufactured before the simulated bone cancellous 24 is filled in the filling cavity 211, the simulated mandibular duct 25 is filled with simulated blood or red silica gel, then two ends of the simulated mandibular duct 25 are sealed by wax and then fixedly arranged in the inner side of the filling cavity of the simulated bone cortex 21, and then the simulated bone cancellous 24 is filled in the filling cavity 211 of the simulated bone cortex 21.
Step three: the multifunctional insert 2 is inserted into an insert positioning slot 11 of the full-mouth mandibular model 1 and fixed by a screw 3.
And the multifunctional plug-in 2 and the full-mouth mandible model 1 form an oral cavity practical training model assembly, and when oral cavity practical training operation is carried out, the oral cavity practical training model assembly is integrally installed on the head model imitation system for practical training operation.
The simulated gum 22 and the simulated cortical bone 21 which have the most basic functions of cutting and sewing are realized, and because the market demand is large, the simulated gum 22 and the simulated cortical bone 21 are combined by mass injection production with a metal mold injection molding machine at low cost, and the gum is molded and encapsulated at the same time. Greatly improves the production efficiency, ensures the product precision and the dimensional stability and reduces the use cost of customers. This is not achieved by conventional casting and bonding processes.
The molding material of the simulated bone cortex 21 is preferably modified thermosetting plastic such as melamine resin, urea resin, epoxy resin, polyurethane and the like, the plastic is more similar to natural bone in machinability and the appearance of hand feeling and cutting scraps is more similar to that of actual clinic compared with thermoplastic plastic, after the simulated bone cortex 21 is coated with the pre-bonding treatment agent, the bonding strength between the soft tissue and the simulated bone cortex 21 after encapsulation and the bonding strength between the soft tissue and the bone cortex of a real person, the simulated bone cortex 21 and the simulated gum 22 or the bonding strength between the simulated bone cortex 21 and the simulated bone film 23 can be different according to the requirements of customers. Some clients do not want to spend much time on the separation operation (such as flap surgery) of the simulated gingiva 22 and the simulated cortical bone 21 because of the limitation of training or examination time, so that the bonding strength is expected to be lower than the actual clinic, and thus, the oral training model can be flexibly selected according to the actual situation, and the use flexibility is better compared with the traditional single bonding strength mode.
Depending on customer needs, it may be selected whether to encapsulate the simulated periosteum 23, if this step is not required, and if desired, two processes may be used to form the simulated periosteum 23 on the simulated cortical bone 21:
a) If the customer needs a large amount or the requirement on the thickness of the simulated periosteum 23 is single and definite, a metal mold is adopted, the simulated cortical bone 21 is put into the mold in advance, LSR (liquid silica gel) or TPE (thermoplastic elastomer) with higher hardness and better toughness is injected into the metal mold by a method of injecting soft rubber for encapsulation and forming, and the simulated periosteum 23 is encapsulated on the simulated cortical bone 21, so that the production efficiency is high;
b) If the customer needs little or has special requirement to the thickness of the simulated periosteum 23, a layer of simulated periosteum 23 can be formed on the simulated cortical bone 21 by adopting a silica gel coating process, and the thickness and the texture of the periosteum can be flexibly adjusted according to the customer needs easily in the mode, and the two modes have higher efficiency than the traditional full-manual manufacturing mode.
The simulated periosteum 23 and the simulated gingiva 22 are made of similar soft rubber materials with different hardness and toughness, and are made of either silica gel or TPE (thermoplastic elastomer), the simulated gingiva 22 is made of soft rubber varieties which are more similar to the natural gingiva in texture, softer, lower in hardness and higher in toughness, and the simulated periosteum 23 is made of soft rubber varieties which are more similar to the natural periosteum in texture, higher in hardness and higher in toughness. Because of the same kind of soft rubber, the joint surfaces of the simulated gingiva 22 and the simulated periosteum 23 can be integrated. In the process, the simulated gingiva 22 is formed by using the same metal mold, and the simulated cortical bone 21 coated with the simulated periosteum 23 is subjected to the second rubber coating forming at the same time of gingiva forming, so that the production efficiency is high, and the product precision can be ensured. Compared with the production mode of sticking fiber mesh cloth on the simulated bone cortex 21 and covering a layer of soft rubber, the production mode of the simulated periosteum 23 and the simulated gum 22 has higher production efficiency and higher molding precision.
If there is a need to develop practical training for planting, it is necessary to add an anatomical structure of the simulated cancellous bone 24. The method for shaping the simulated cancellous bone 24 is: a material that is easier to cut than cortical bone is poured into the filling cavity of the simulated cortical bone 21, thereby simulating cancellous bone. The material of the simulated cancellous bone 24 can be foamed polyurethane or other materials with loose modified materials. The multifunctional plug-in 2 with the simulated cancellous bone 24 material is a 'model plug-in for practical training of incising and suturing implant', and can increase a series of practical training courses of implant and repair operations such as alveolar ridge trimming, positioning, hole preparation, implant implantation, implant repair, bone implantation and the like. When it is desired to add characteristics of the mandible so that practical training of the implant surgery in the posterior mandibular area is more realistic, the simulated mandible 25 may be installed in the filling cavity 211 of the simulated cortical bone 21, and since the mandible is shaped by 3d printing, the simulated mandible 25 may be filled with simulated blood or red liquid silica gel, and both ends thereof may be sealed with wax, or may be sealed with other structures or substances, and after the red liquid silica gel solidifies, the simulated mandible 25 assumes a vascular texture. The simulated blood is preferably made of gel materials, and is not easy to exude from the sealing part. Before the simulated cancellous bone 24 material is poured, the simulated mandibular duct 25 is assembled into the filling cavity of the simulated cortical bone 21 by bonding (or hot melting or other connecting modes such as screw 3 connection, etc.), and after bonding and retention, the simulated cancellous bone 24 material is injected. The finally formed product is the model plug-in for practical training of incisional suture planting with mandibular duct.
The oral cavity training model plug-in is completely 3d digital design, and main anatomical structures are manufactured through a metal die or 3d printing, so that the size of the anatomical structures and the distance between the structures are very accurate, the numerical values of the size and the distance position are provided for customers, and the customers can perform accurate clinical operation simulation operation without photographing CT (computed tomography) sheets on the model. And because the materials used by each part of the model plug-in unit of the utility model can be clearly developed through X rays, the practical training of the oral imaging by using the model is also completely possible for customers. The traditional model parts are assembled together after being manually formed, the dimensional accuracy is not guaranteed, the anatomical structure size and the distance between the structures can be determined only by CT (computed tomography), but the used materials are often common materials in the market, and clear development cannot be obtained by CT.
