开展牙外科正畸术,理想的截骨工具是手术取得满意效果的重要条件之一。目前市面上不易购到满意的薄刃骨凿,用一般骨凿改制也难以做出兼备足够长度和一定硬度的薄刃。我们利用工业用钢锯,设计制作了一套厚仅0.6mm的简易薄刃骨凿(见附图)。从1985年3月至1986年6月进行了30例牙外科正畸术(共44牙),使用效果良好,尤在凿开重叠错位牙时不易损伤牙周膜或牙齿而特别显示其优越性,现介绍如下: 选柄长约10cm、宽约1cm、厚约0.5cm之旧单头刮匙,于变细处截断,磨平刮匙柄断端使成长方形条状,并将断端1/3的宽度磨窄为0.8cm;顺长度的方向用钢锯在中央锯出—长7cm的夹槽;于槽内套进钢锯条,据钢锯条小孔的实际位置和大
To carry out orthodontics orthodontics, the ideal osteotomy tool is one of the important conditions for satisfactory surgical results. Currently available on the market is not easy to buy a thin blade osteotome, osteotomy with the general restructuring is difficult to make both thin enough to have a certain length and hardness. We use the industrial hacksaw, designed and manufactured a set of simple thin bone chisel thickness 0.6mm (see photo). From March 1985 to June 1986, 30 cases of orthodontics (44 teeth in total) were performed with good effect, especially in the case of overlapping dislocation of teeth, which is not easy to damage periodontal ligament or teeth , Are introduced as follows: Select a handle length of about 10cm, width 1cm, thickness of about 0.5cm of the old single-head curette, cut off at the thinning, grinding flat end of the handle handle to make a square bar, and the broken end 1 / 3 width narrowed to 0.8cm; along the length of the direction of sawing in the center with a hacksaw - 7cm long slot folder; set in the slotted hacksaw blade, according to the actual location of hacksaw holes and large
