Abstract
The utility model relates to a teaching-used periodontal surgery model former. The former comprises a cavity wall made of elastic material, and a cavity enclosed by the cavity wall. The upper end of the cavity wall is opened. The cavity includes an upper base chamber and a lower molding chamber. The base chamber is polygon shaped, and the lower end of the base chamber is provided with a vestibule. The molding chamber is internally provided with a teeth and mandible seat on which teeth holes adaptive to a corresponding dentition are arranged. The beneficial effects of the utility model are that the former can be used for making a gypsum model by repeatedly pouring, and the gypsum model obtained by pouring can be conveniently taken out of the former; the model made by pouring can represent the characteristics of periodontal symptoms, providing intuitive and ideal effects for teaching, for example, while being combined with artificial gums, the model can be used to carry out operation simulation by students and teachers; besides, the model can be seen clearly and is healthy and convenient while being used for teaching, so that the former is applicable to the teaching of various periodontal surgery operations.
Description
Technical field
The utility model relates to pedagogical model, relates in particular to a kind of teaching periodontal surgery model former.
Background technology
Periodontal surgery is in periodontal treatment, to eliminate a kind of methods for the treatment of that oral pocket the most extensively adopts.The method adopts operative incision, gum is separated with organizing of below, form gingiva tissue lobe, expose root face and the alveolar bone of diseased region, strike off pathological tissues and bacterial plaque dental calculus to facilitate, and sew up on gingival flap is resetted in place, reach the object of eliminating oral pocket or oral pocket being shoaled.
So periodontal flap surgery is the key content of Periodontics course teaching, particularly otch technology and suturing skill are the emphasis of simulation teching.Owing to lacking suitable simulation teching material, general some householder methods that adopt at present, such as model demonstration method, but static demonstrating model differs greatly with the requirement of analogue technique training; Adopt in addition pig jaw sham operated, but with pig jaw the simulated object as conventional teaching, because the reasons such as quantity, cost exists certain difficulty in actual use; In addition, the pig many places that are suitable for slaughtering, in for the tooth phase, are generally deciduous teeth, in the sham operated of imparting knowledge to students, are easy to come off, and inconvenience is scraped and controlled, and field of operation cannot be simulated people's osseous lesion symptom form.Make like this, in periodontal Surgical Teaching, to lack suitable simulation material.
Summary of the invention
The purpose of this utility model is to provide a kind of convenience to prepare and have the former of human body periodontosis symptom structure.Its concrete technical scheme is as follows.
Described former, comprises that Bi Heyou chamber, the chamber wall of being made up of resilient material crowds around the cavity forming, and wall upper end, described chamber is open, and described cavity comprises the pedestal chamber on top and the forming cavity of bottom, and described pedestal chamber is polygon cavity, and lower end, pedestal chamber is provided with vestibular ditch; In described forming cavity, be provided with tooth jaw pedestal, this tooth jaw pedestal is provided with the tooth hole suitable with corresponding denture.
The further setting of described former, also comprises that upper end is provided with full denture or the part denture of alveolar bone, and the some teeth in described full denture or part denture are placed in corresponding tooth hole.
The further setting of described former, described at least one, the alveolar bone of tooth upper end is provided with the periodontosis symptom structure that bone is damaged.
The further setting of described former, described polygon cavity be there is certain angle by multiple and vertical direction plane successively having of forming of handing-over between two move back the polygon ring plain that pulls out tapering.
The further setting of described former, described resilient material is silicon rubber.
The beneficial effects of the utility model are, owing to adopting high strength elastic material to make, can repeatedly fill with plaster cast; Move back the polygon ring plain that pulls out tapering and can facilitate plaster cast to take out from former due to elastic deformation groove and having being set on the step surface of lower end, pedestal chamber; The model of recording can be expressed periodontosis symptom characteristic, intuitively satisfactory for result in teaching, then after combining use with artificial gum, student and teacher all can carry out surgical simulation easily on model, get a clear view, hygienic and convenient.Can be conveniently used in various periodontal operation teaching.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model former.
Fig. 2 is the schematic diagram of the A-A of former shown in Fig. 1 section.
Fig. 3 is the model of making of former shown in Fig. 1.
In figure: the 1st, chamber wall, 2 cavitys, 21 pedestal chambeies, 211 planes, 212 vestibular ditches, 22 forming cavity, 221 tooth jaw pedestals, 222 tooth holes, 3 teeth, 31 alveolar bones, the periodontosis symptom structure that 32 bones are damaged, 4 pedestals.
Embodiment
Contrast Fig. 1,2, former of the present utility model comprises the chamber wall 1 of being made up of resilient material and is crowded around the cavity 2 forming by chamber wall.The upper end of chamber wall 1 is open, comprises the forming cavity 22 of pedestal chamber 21 and the bottom on top, and pedestal chamber 22 is polygon cavity, and lower end, pedestal chamber is provided with vestibular ditch 212; In forming cavity 22, be provided with tooth jaw pedestal 221, this tooth jaw pedestal is provided with the tooth hole 222 suitable with some teeth in corresponding denture.
Above-mentioned periodontal surgery model former also comprises full denture or part denture, can express the damaged symptom structure of bone on alveolar bone in order to make this former institute mold type, tooth 3 upper ends in full denture or part denture arrange alveolar bone 31, and the periodontosis symptom structure 32 that bone is damaged is set at least one tooth, incorporated by reference to referring to Fig. 3.The tooth of full denture or part denture is placed in corresponding tooth hole 222.
Further, for the ease of the demoulding easily of former institute mold type, the polygon cavity in pedestal chamber 22 is to be formed to have by 7 planes 211 that have certain angle with vertical direction successively handing-over between two to move back the heptagon ring plain that pulls out tapering.
Former of the present utility model adopts silicon rubber elastic material to make, and has certain thickness, can tolerate certain pressure, has good toughness, is convenient to record Reusability after model.
During with former analogue formation of the present utility model, inject gypsum to cavity 2 by the open port in chamber wall 1 upper end, after gypsum solidifies, plaster cast is peeled off out from former the periodontal surgery plaster cast forming as shown in Figure 3.On this model, be provided with full denture, the complete all teeth of denture upper end arranges respectively alveolar bone 31, and periodontosis symptom structure is set on alveolar bone, this symptom structure mainly contains the absorption of alveolar bone horizontal type and vertical-type absorbs symptom structure, and example is provided with respectively the periodontosis symptom structure 32 that vertical-type bone is damaged as shown in Figure 3 on a labial teeth and a backteeth.
