定位板的制作:在模型外科已拼对好的石膏模型上,经涂分离剂,以自凝塑料捏成条状,铺在下颌牙弓(牙合)面,咬合上下牙弓模型,修整唇颊侧,形成全牙弓的双面(牙合)板。待塑料凝固后取下打磨备用。(牙合)板的厚度要求约2mm,距离切缘2mm～2.5mm,便于钻孔供术中固定使用。 由于已将模型外科上拼对的牙位记录在定位(牙合)板上,术中只要将各已分离的牙、骨块在定位板上就位固定,使手术变得简单,易于掌握而缩短了手术时 Positioning plate: the model surgery has been spell good plaster model, coated with a separating agent, self-curing plastic kneading into strips, laying in the mandibular arch (occlusal) face, bite the upper and lower dental arch model, trim the lip Buccal side, the formation of the entire arch double-sided (occlusal) board. Remove the plastic solidification after grinding aside. (Occlusal) board thickness of about 2mm, from the cutting edge 2mm ~ 2.5mm, easy to drill for the operation of the fixed use. Since the model has been surgical pairs of teeth recorded in the position (occlusal) board, intraoperative as long as the teeth have been separated in place on the positioning of the bone plate fixation, the surgery becomes simple and easy to grasp and Shorten the operation time
