Description
Technical field
The utility model relates to a kind of dentistry training pattern of imparting knowledge to students for dentistry and practising.
Background technology
Stomatologic teaching requires very high to operability, so practical operation is requisite link in teaching, therefore, dentistry training pattern is widely used in the teaching field of each high dentistry universities and colleges.
Chinese patent 200420113615.7 discloses a kind of root canal therapy simulated teaching aid, simulation head body is provided with the upper and lower gnathode of emulation, emulation mandible model is connected with simulation head body by adjusting knob, emulate upper and lower gnathode and be provided with emulation denture, each pathology tooth movement be plugged on emulate upper and lower gnathode alveolus in.Pathology tooth is two lobe combined types.During training root canal therapy, first root pipe is pulled out, pathology tooth is being opened determine whether to look for right pathology tooth.The shortcoming of this model is: can only practise judging which is root pipe pathology tooth.And the process of the root canal therapy of reality is: 1. clap X-ray photographs, determine affected part structure and operation plan.2. impose local anaesthesia.3. bore and open tooth, remove the dentine addled.4. open pulp cavity, take out downright bad dental pulp.5. expand root pipe with pulp canal drill.6. rinse root pipe with thimerosal (such as sodium chlorate solution) inner.7., with special material filling root pipe, ensure to be in germ-free condition for a long time.8. fill up getting into the cave of tooth, or corona is installed.As can be seen here, this model cannot simulate the implementation step of actual root canal therapy.
Summary of the invention
There is to overcome prior art the shortcoming of the implementation step cannot simulating actual root canal therapy, the utility model provides a kind of implementation step of the actual root canal therapy that can do simulated exercises, and can the root canal tooth model of replaceable bone block of repeated multiple times use.
The root canal tooth model of replaceable bone block, comprises base, alveolar bone, gum and denture, and alveolar bone comprises fixing bone block and interchangeable movable bone block, and fixing bone block is fixed on base, and base is provided with the slot coordinated with movable bone block; Gum covers fixing bone block and movable bone block; Movable bone block, gum and denture are replaceable; The quantity at least 1 of movable bone block, movable bone block is provided with the groove of simulation tooth socket, and tooth model is fixed in groove, is provided with pulp cavity and root pipe in this tooth model, is filled with the soft bar for analog neuron in pulp cavity and root pipe.This soft bar is made up of the soft material such as rubber or silica gel.Root canal model is upper gnathode, or mandibular model, or has upper gnathode and the mandibular model of occluding relation for a pair.
Further, tooth model is bonded and fixed in the groove of movable bone block.
Or be provided with extension bottom tooth model, screw thread has been attacked in extension, the bottom portion of groove of movable bone block is provided with the screw engaged with extension.
Further, in the cone with Morse's taper bottom movable bone block, base is provided with the taper hole with Morse's taper, and base is fixed in the grafting of movable bone block.
Further, denture comprises conventional tooth model and pathology tooth model, and the tooth model being fixed on movable bone block is pathology tooth, and conventional tooth is fixed on fixing bone block, and the root of the tooth of conventional tooth model is Morse's taper, and the root of the tooth of pathology tooth model is nature root of the tooth shape; Fixing bone block is provided with the tooth socket structure with Morse's taper, and conventional tooth model is coordinated by Morse's taper with tooth socket structure.
Further, movable bone block is provided with at least one pathology tooth model.
Further, movable bone block is made up of the weaker zone of outer field tight zone and internal layer, and weaker zone is porous structure.Tight zone is for simulating the cortex bone of human body, and weaker zone for simulating the cancellous bone of human body, thus makes training pattern more close to real dentale mechanical property.
The utility model in use, when carrying out root canal teaching mode, first on the occlusal surface of the pathology tooth model of movable bone block, bore a hole with high speed handpiece, make apparatus can enter root of the tooth smoothly, then with broach, " dead dental pulp " is removed, then carry out the expansion of root pipe, sterilization, envelope medicine etc. follow-up from operation, finally use packing material to fill canalis radicis dentis, complete the teaching process of root canal.
The utility model has the advantage of: 1, the module of training is made movable bone block, when repeatedly training causes bone block to damage, only need change bone block, fixing bone block and base still can continue to use.2, movable bone block and base can make respectively, standardization can be adopted to produce in batches for the base and fixing bone block part that do not carry out training and operation, personalized customization is carried out to needing the movable bone block carrying out training and operation, multiple movable bone block use and a base can be arranged in pairs or groups, both improve production efficiency, and can individual operation training be carried out again.3, the mechanical property of movable bone block is close to the mechanical property being really dentale, and the authenticity of simulation is good.The bone block of 4, dentistry being trained makes movable bone block, can exchange with the movable bone block of other training functions, as kind of a movable bone block for tooth training, and the movable bone block etc. of periodontosis training.5, various activities bone block can be made according to the reality situation of having tooth pulled out, multiple real exodontia situation can be simulated.
