The embodiments described below are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. The "left" and "right" positions mentioned in the utility model are the "left" and "right" positions in human anatomy.
[0035] Please refer to Figures 1 to 9 The utility model provides a kind of comprehensive tooth grinding training model, technical scheme is as follows:
[0036] A kind of comprehensive tooth grinding training model, including maxilla 1 and mandible 2, maxilla 1 includes upper alveolar 3, and upper alveolar 3 is installed with upper teeth 4, mandible 2 includes lower alveolar 5, and lower alveolar 5 is installed with lower teeth 6, upper alveolar 3 and the alveolar fossa 7 of corresponding tooth shape, size consistent with corresponding tooth of the lower alveolar 5 corresponding position are all set up, the through hole 71 of each alveolar fossa 7 bottom is set up, to facilitate the dismounting upper teeth 4 and lower teeth 6, the through hole 71 of each alveolar fossa 7 bottom can reduce the suction generated when tooth is pulled out tooth and lower alveolar 5 and reduce the pressure generated when tooth is installed tooth and lower alveolar 5, facilitate dismounting tooth.
[0037] Refer to Figures 1 to 9The upper teeth 4 include upper posterior teeth 41 and upper anterior teeth 42, and the lower teeth 6 include lower posterior teeth 61 and lower anterior teeth 62, the problematic upper posterior teeth 41 include right upper second molar 411, right upper first molar 412, right upper second premolar 413, right upper first premolar 414, left upper second molar 415, left upper first molar 416, left upper second premolar 417 and left upper first premolar 418, and wisdom teeth are installed behind the right upper second molar 411 and the left upper second molar 415, the upper anterior teeth 42 are two normal-shaped central incisors, two normal-shaped lateral incisors and two normal-shaped canines, each tooth corresponds to a corresponding tooth position one-to-one, and each tooth is installed on the upper alveolar arch 3 through a corresponding alveolar socket 7.
[0038] The lingual tooth part of the right upper first molar 412 and the right upper second molar 411 of the upper posterior teeth 41 does not form a correct occlusion relationship with the corresponding teeth of the mandible 2, and the tooth part of the right upper first molar 412 and the right upper second molar 411 on the lingual side bears the wear of the entire right upper first molar 412 and the right upper second molar 411, so the right upper first molar 412 and the right upper second molar 411 present significant wear and lose the normal tooth shape, and look like there is no tooth tip and are relatively flat;
[0039] The buccal tooth tip of the right upper first molar 412 and the right upper second molar 411 of the upper posterior teeth 41 protrudes significantly, and the tooth protrudes into a sharp tooth tip or a conical protrusion, because the buccal tooth of the right upper first molar 412 and the right upper second molar 411 does not form a correct occlusion relationship with the corresponding teeth of the mandible 2, so the buccal tooth of the right upper first molar 412 and the right upper second molar 411 does not have corresponding wear teeth, so the buccal tooth part of the right upper first molar 412 and the right upper second molar 411 wears less, and the tooth tip protrudes significantly;
[0040] The lingual tooth part of the left upper second molar 415 and the left upper first molar 416 of the upper posterior teeth 41 does not form a correct occlusion relationship with the corresponding teeth of the mandible 2, and the tooth part of the left upper second molar 415 and the left upper first molar 416 on the lingual side bears the wear of the entire left upper second molar 415 and the left upper first molar 416, so the left upper second molar 415 and the left upper first molar 416 are both flat and have no tooth tip shape, and the interdental gap width between the left upper second molar 415 and the left upper first molar 416 exceeds the normal range of the gap width between adjacent teeth, for example, the gap between normal adult teeth is less than 0.2 mm, but the gap between the left upper second molar 415 and the left upper first molar 416 is greater than 0.2 mm, and may be 0.2 to 0.5 mm;
[0041] The buccal side part of the left upper second premolar 417 and the left upper first premolar 418 of the upper posterior teeth 41 does not form a correct occlusion relationship with the corresponding teeth of the lower jaw 2, so the buccal side teeth of the left upper second premolar 417 and the left upper first premolar 418 have no corresponding wear teeth, and the buccal side teeth of the left upper second premolar 417 and the left upper first premolar 418 are less worn, and the cusps are significantly high, and the cross section of the cusps of the left upper second premolar 417 and the left upper first premolar 418 is a high triangular shape;
[0042] And the edge ridge height of the left upper second premolar 417 and the left upper first premolar 418 is inconsistent, and exceeds the edge ridge height of the adjacent teeth, the normal edge ridge height of the left upper second premolar 417 and the left upper first premolar 418 is 0.8mm to 1.2mm, when the edge ridge height of the left upper second premolar 417 is higher than the normal edge ridge height of the left upper first premolar 418, it will cause the adjacent contact point to be too tight or occlusion interference, similarly, when the edge ridge height of the left upper first premolar 418 is higher than the normal edge ridge height of the left upper second premolar 417, it will also cause the adjacent contact point to be too tight or occlusion interference, and the interdental space width between the left upper second premolar 417 and the left upper first premolar 418 exceeds the normal range of the interdental space width commonly existing between adjacent teeth, for example, the interdental space between normal adult teeth is less than 0.2mm, but the interdental space between the left upper second premolar 417 and the left upper first premolar 418 is greater than 0.2mm, and may be 0.2 to 0.5mm.
[0043] Reference Figures 1 to 9 The lower posterior teeth 61 include the right lower second molar 611, the right lower first molar 612, the right lower second premolar 613, the right lower first premolar 614, the left lower second molar 615, the left lower first molar 616, the left lower second premolar 617 and the left lower first premolar 618, the right lower second molar 611 and the left lower second molar 615 are installed with wisdom teeth at the back, the lower anterior teeth 62 are two normal shaped incisors, two normal shaped lateral incisors and two normal shaped lateral incisors, each tooth corresponds to the corresponding tooth position one by one, and each tooth is installed on the lower alveolar arch 5 through the corresponding alveolar fossa 7;
[0044] The lingual side part of the right lower second molar 611 and the right lower first molar 612 does not form a correct occlusion relationship with the corresponding right upper second molar 411 and right upper first molar 412 of the upper jaw 1, and the lingual side part of the right lower second molar 611 and the right lower first molar 612 does not form a correct occlusion relationship with the right upper second molar 411 and the right upper first molar 412, so the cross section of the cusps of the right upper second molar 411 and the right upper first molar 412 is a high triangular shape;
[0045] The buccal side part of the right lower second molar 611 and the right lower first molar 612 bears the abrasion of the whole right lower second molar 611 and the right lower first molar 612, so the buccal side part of the right lower second molar 611 and the right lower first molar 612 is in the shape of low flat without cuspid;
[0046] The marginal ridge height of the right lower second molar 611 and the right lower first molar 612 is inconsistent, exceeding the marginal ridge height of the adjacent teeth. The marginal ridge height of the right lower second molar 611 and the right lower first molar 612 of the normal lower jaw 2 is about 0.8mm to 1.5mm. When the marginal ridge height of the right lower second molar 611 is higher than the normal marginal ridge height of the right lower first molar 612, it will cause the tight interproximal contact point or occlusal interference. Similarly, when the marginal ridge height of the right lower first molar 612 is higher than the normal marginal ridge height of the right lower second molar 611, it will also cause the tight interproximal contact point or occlusal interference. In addition, the interproximal width between the right lower second molar 611 and the right lower first molar 612 is wider, and the normal range of the interproximal width is less than 0.2mm, but the interproximal width between the right lower second molar 611 and the right lower first molar 612 exceeds the normal range;
[0047] The lingual side part of the right lower second premolar 613 and the right lower first premolar 614 does not form the counter bite relationship with the right upper second premolar 413 and the right upper first premolar 414, so the cuspid cross section of the right lower second premolar 613 and the right lower first premolar 614 is in the shape of high triangle. Therefore, the buccal side part of the right lower second premolar 613 and the right lower first premolar 614 bears the abrasion of the whole right lower second premolar 613 and the right lower first premolar 614, so the buccal side part of the right lower second premolar 613 and the right lower first premolar 614 is in the shape of low flat without cuspid;
[0048] The marginal ridge height of the left lower second molar 615 and the left lower first molar 616 is inconsistent, exceeding the marginal ridge height of the adjacent teeth. The marginal ridge height of the left lower second molar 615 and the left lower first molar 616 of the normal lower jaw 2 is about 0.8mm to 1.5mm. However, when the marginal ridge height of the left lower second molar 615 is higher than the normal marginal ridge height of the left lower first molar 616, it will cause the tight interproximal contact point or occlusal interference. Similarly, when the marginal ridge height of the left lower first molar 616 is higher than the normal marginal ridge height of the left lower second molar 615, it will also cause the tight interproximal contact point or occlusal interference. In addition, the lingual side part of the left lower second molar 615 and the left lower first molar 616 does not form the counter bite relationship with the left upper second molar 415 and the left upper first molar 416 of the upper jaw 1, so the lingual side part of the left lower second molar 615 and the left lower first molar 616 has less abrasion, so the cuspid cross section of the lingual side part of the left lower second molar 615 and the left lower first molar 616 is in the shape of high triangle;
[0049] The marginal ridge height of the left lower second premolar 617 and the left lower first premolar 618 is inconsistent, exceeding the marginal ridge height of adjacent teeth. The normal marginal ridge height of the left lower second premolar 617 and the left lower first premolar 618 is about 0.8-1.2 mm, but if the marginal ridge height of the left lower second premolar 617 is higher than the normal marginal ridge height of the left lower first premolar 618, it will cause tight interproximal contact points or occlusal interference, and vice versa. In addition, the interproximal gap width between the left lower second premolar 617 and the left lower first premolar 618 exceeds the normal range of adjacent interproximal gap width.
[0050] Referring to Figures 1 to 9 Because of the abnormal occlusal relationship between the upper and lower jaws 2, the flat teeth on the lingual side of the right upper second molar 411 and the flat teeth on the buccal side of the right lower second molar 611 fit each other, the flat teeth on the lingual side of the right upper first molar 412 and the flat teeth on the buccal side of the right lower first molar 612 fit each other, the flat teeth on the lingual side of the right upper second premolar 413 and the flat teeth on the buccal side of the right lower second premolar 613 fit each other, and the flat teeth on the lingual side of the right upper first premolar 414 and the flat teeth on the buccal side of the right lower first premolar 614 fit each other.
[0051] Referring to Figures 1 to 9 The flat teeth on the lingual side of the left upper second molar 415 and the flat teeth on the buccal side of the left lower second molar 615 fit each other, the flat teeth on the lingual side of the left upper first molar 416 and the flat teeth on the buccal side of the left lower first molar 616 fit each other, the flat teeth on the lingual side of the left upper second premolar 417 and the flat teeth on the buccal side of the left lower second premolar 617 fit each other, and the flat teeth on the lingual side of the left upper first premolar 418 and the flat teeth on the buccal side of the left lower first premolar 618 fit each other, forming an abnormal occlusal curve, which needs to be restored to normal by the student through grinding operation.
[0052] Referring to Figures 1 to 9Since the comprehensive tooth adjustment training model is used for students to train operation, in order to facilitate repeated practice, the standard head mold interface of the utility model makes the utility model be able to be seamlessly installed on the standard dental training head mold, the student is convenient to simulate the clinical actual scene, and each upper tooth 4 and lower tooth 6 are designed into a detachable style, since the buccal side tooth cusps of the left upper first premolar 418, the left upper second premolar 417, the right upper first premolar 414 and the right upper second premolar 413 (premolar) and the left upper first molar 416, the left upper second molar 415, the right upper first molar 412 and the right upper second molar 411 (posterior molar) of the maxilla 1 are high and towering, the lingual side part of teeth is low and flat, and the lingual side tooth cusps of the left lower first premolar 618, the left lower second premolar 617, the right lower first premolar 614 and the right lower second premolar 613 (premolar) and the left lower first molar 616, the left lower second molar 615, the right lower first molar 612 and the right lower second molar 611 (posterior molar) of the mandible 2 are high and towering, the buccal side part of teeth is low and flat, forming the occlusion problem opposite to the maxilla 1, therefore, the student can practice adjusting the morphology and height of the high and towering tooth cusps, grinding the teeth to overflow the groove, improving the occlusion function and tooth morphology, adjusting the height of the marginal ridge, making the height of the marginal ridge between two teeth consistent, increasing the lateral space, forming the reasonable lateral space through the practice and adjustment, and also adjusting the longitudinal jaw curve and the transverse jaw curve through the adjustment and repair, so that the longitudinal jaw curve and the transverse jaw curve return to normal, and the correct occlusion curve is established, the model tooth material of the utility model is wear-resistant material, for example, resin material, the resin material includes polyurethane resin, the polyurethane resin has excellent wear resistance and toughness, high strength, and restores the tooth texture and is easy to process and color, the utility model can withstand the adjustment for many times, and the model tooth shape is lifelike and conforms to the anatomical characteristics.
