Abstract

The present invention belongs to a teaching appliance for the experiment teaching of mouth cavities, which comprises a base support composed of an upper jaw and a lower jaw made of elastic materials, wherein gums which form the base support are provided with alveolar sockets for installing isolated teeth, and the base support is also provided with a fixed connecting device fixedly connected with a jaw rest of a metal head imitating model. The model arranged on the jaw rest of the metal head imitating model can simulate the mouth cavity of a person to ensure that students feel like operating in the mouth cavity of a patient, so that the conditions of the experiment teaching are adjacent to those of clinics so as to rule the basic operation skills and theory to practice abilities of students and train the thinking abilities of clinical judgment and the correct operation abilities.

Description

A kind of high resiliency tooth  model

The invention belongs to the teaching aid that the experimental teaching of a kind of oral cavity is used.

The subject that dentistry is a practicality, application is very strong, except that the classroom instruction of Theory Course, the experimental teaching important teaching link that is absolutely necessary.The knowwhy that it can not only be consolidated, enrich, deepen and verify on the classroom to be lectured, the more important thing is and cultivate student's connection between theory and practice, the clinical judgment thinking ability of science and correct operating ability, lay a solid foundation for working alone after bedside practice and the graduation.At present, the many sequential operation exercises that add diamond spar tooth, stripped tooth by gypsum tooth, imitative head model of oral cavity Experimental Teaching Method both domestic and external.Used gypsum tooth, diamond spar tooth lack the variation difference of sclerous tissues on the laboratory, do not have the pulp cavity structure, with the human body dermal tooth in essence difference are arranged.For a long time, the oral cavity experimental teaching all adopts the hand-held method that exsomatizes tooth to operate this teaching, experimental technique not only lacks position to be regulated, the utilization of hand fulcrum, tooth position, front and back and the variation of going up mandibular position, and illumination and mirror image operation also can't be trained, employed tooth and human body dermal tooth also have difference in essence, thereby caused laboratory operant level and bedside practice requirement seriously to disconnect, the major defect of student's dentistry structure of knowledge and ability and the deficiency of clinical basic operating technical ability have also been caused, the content that the time that causes the teacher who is with bedside practice often will take out bedside practice is mended laboratory has a strong impact on implementing and implementing of whole teaching programme.

The object of the present invention is to provide a kind of oral cavity, the teaching mould of the dermal tooth that is fit into that can the anthropomorphic dummy, with the actual effect of aspis laboratory, accelerate the student to study the science by the understanding of knowledge and intensification student's memory.

The present invention realizes like this, it comprises a base, this base is the last lower jaw made from resilient material, is provided with the tooth socket that the tooth that exsomatizes is used is installed on the gum that this base constitutes, and the fixed connection apparatus of fixedlying connected with the imitative head model jaw frame of metal also is installed on this base.During use, the stripped tooth that day chamber outpatient service is collected carries out disinfection, and be installed in the tooth socket on the base by the tooth position of tooth in the oral cavity, through fixed connection apparatus upper and lower jaw base is divided on the upper and lower jaw frame that is not fixedly mounted on the imitative head model of metal in addition then, so just constituted the experimental teaching model of similar human oral cavity.Utilize this model can finish the major part experiment of oral medicine,, also can be used for the operation trainings such as tooth extraction of Prosthodontics experiment and oral surgery as plombage, root canal, mummification of pulp, resinifying therapy, clean scaling, stabilization of loosen teeth etc.

Can thoroughly change in the experimental teaching with this tooth  model, the situation of the hand-held tooth operation of exsomatizing of student, make the student utilize the training of this model manipulation the time to feel as at the disease population transluminal operation, existing position is regulated, the utilization of hand fulcrum, the variation of tooth position, front and back and last mandibular position, illumination is arranged again, examination apparatus commonly used is (as mouth mirror, probe, tweezers etc.) operation, the actual effect of outstanding laboratory, quickening is to the understanding of scientific principle opinion and enhance memory, cultivate the student thus sturdy basic theoretical knowledge is not only arranged, also possess general stronger thinking ability and the strictness of clinical speciality, the clinical manipulation ability of standard, simultaneously also improve student's independent adaptability to changes and correct operating ability, strengthened the adaptability that the student enters bedside practice.People's dermal tooth is installed in the oral cavity of the tooth  pattern die personification made from rubber, has more the sense of reality than gypsum tooth or other emulation teeth, and it is directly perceived, lively, image, appeal are strong, for laboratory teaching has injected new vitality.This model adopts resilient material to make base, and the whole gingiva color that adopts is given the experimenter sense of reality with gum from color and elasticity, and the tooth that will exsomatize then inserts tooth socket, simulates the truly feels in oral cavity.This tooth  model can use repeatedly by changing the tooth that exsomatizes, and has stronger use value, can improve the current experiments teaching condition to greatest extent.In addition,, can also break through some difficult point and emphasis in the conventional teaching, eliminate abstractness, the content of coursesization be embarrassed easily, and can improve the specific aim of experimental teaching with the teaching that experimentizes of this model.Moreover, this model is experienced informational function owing to strengthened human organ, make the student can intuitively, clearly observe the difficult point and the main points of operation, in limited time and space, operation is formed concrete impression, the opinion of studying the science is digested in experimentation, basic skills obtain comprehensive and comprehensive training, have improved the acceptability of laboratory teachings, and also help the ideology that son is cultivated student's innovation.

Fig. 1 is a structure principle chart of the present invention;

Fig. 2 is the structure principle chart of another kind of duty of the present invention;

Fig. 3 is the A-A cut-open view of Fig. 1;

Fig. 4 is the B-B cut-open view of Fig. 2.

The present invention will be described in detail below in conjunction with accompanying drawing.

Base of the present invention 2 is made by resilient material, makes the upper jaw and lower jaw as requested, and said resilient material generally refers to rubber, or is similar to the material of rubber.If manufacture base 2, preferably use the silicon rubber (this model promptly uses this material) of high resiliency anti tear with rubber.On the gum of the base 2 that constitutes the upper jaw or lower jaw, be provided with and the corresponding tooth socket 1 of people's teeth patterning, the tooth 4 that exsomatizes is installed in this tooth socket 1.The fixed connection apparatus 3 of fixedlying connected with the imitative head model jaw frame 5 of metal also is installed on this base 2, and this fixed connection apparatus 3 can be a coupling bolt, also can be formations such as connecting thread hole or connection chuck.

In order to make the student can practise the technical ability of having tooth pulled out, also the tooth 4 that exsomatizes can be adhesively fixed in the groove nest 1 on the base 2.
