The present application relates to a kind of personalized orthodontic bite gum, the bite gum is used to cooperate with the use of invisible aligner, the bite gum is horseshoe structure in horizontal plane view, it is wedge structure of back thin front thick in sagittal plane view;The bite gum includes bite gum pad, buccal side, lingual side, the buccal side and the lingual side extend to dental arch buccal side and lingual side from the bite gum pad;The bite gum is provided with the avoidance of corresponding arrangement with the invisible aligner, the avoidance is used to avoid weak position on the invisible aligner.The bite gum provided by the present application is mainly aimed at the cases of tooth extraction, tooth defect, replacement tooth period, tooth occlusal surface design, etc.Special device case, by setting avoidance, the bite gum can avoid weak position on the invisible aligner, prevent the deformation of aligner due to the use of bite gum, affect the treatment effect, reduce the use requirement to patient, improve the use efficiency of bite gum, save time.

The utility model relates to a hot-rolled flat-bulb steel embedded detachable hole pattern guide plate device, which comprises a first guide plate, a second guide plate, a wear-resisting plate and a fastener, the first guide plate and the second guide plate are arranged on two sides of a rolled piece running channel at an inlet of a rolling mill, a groove is arranged on the inner side of the first guide plate, the wear-resisting plate is arranged in the groove, and the wear-resisting plate is contacted with one side of a rolled piece ball head. And the wear-resisting plate is fixedly connected with the guide plate I through a fastener. The guide plate has the advantages that the detachable wear-resisting plate structure is adopted, after the wear-resisting plate is damaged, the guide plate does not need to be detached, only the wear-resisting plate needs to be replaced, and guide plate consumption and replacement frequency are reduced. And the wear-resisting plate is adopted, so that the biting of the rolled piece can be more accurately guided, steel clamping accidents are reduced, the product yield is improved, and the production efficiency is improved.

The utility model relates to medical forceps technical field, concretely relates to an improved bone rong, including the bone rong formed by the two forceps body connected through hinge screw, still include: mounting screw, recess, the recess sets up in the mouth position of bone rong, and the mouth position occlusal surface is set into dentate; Two The forceps body is fixedly connected with elastic member through mounting screw. The jaw recess can be increased by widening the jaw of bone rong, so it can accommodate larger, more bone block, in addition, the blade on both sides of the jaw does not easily form interference when trimming large bone block; The jaw is toothed, the tooth tip contacts the bone surface when using, reduces the contact area, under the condition of equivalent force, the contact area reduces, and the pressure increases, so the bone rong can be more smoothly bitten into the bone surface and cut off the bone block, in other words, this design can save the effort, and prevents skidding when using.
