口腔科常用的小器械很多,有时由于质量较差或使用不当也易折损。我们为了节约,尽量采取翻新、改造等方法来利用这些废物。现将点滴经验介绍出来共同研究)1.牙挺尖端折断或卷曲形,可用砂轮或磨石尖磨改,大致恢复其原来形状再使用。2.挖器、釉质凿、洁牙器的工作端折损后可用砂轮或磨石尖磨改成原来形状再用,或磨扁作为牙龈分离器用,再或磨改成单斜面的尖端作为根尖剔出器,(根尖挺)用。3.棉花鑷尖端折断或卷曲变形,可用技工论矫正之,同时亦可用砂轮或磨石尖磨改修正再用。若尖端折损过甚,可从鑷子两臂的联合部搬断,分成两片,再磨扁尖端作为牙龈分离器用。4.冲洗根管用的弯针头,可利用废针头放在酒精灯火焰上烧红,弯成适当的弯度使用。5.探针弯曲变形,可放在酒精灯火焰上烧红(火),用技工钳矫正,恢复其原来形状,然后再烧红并立即浸入冷水中,以恢复其原来硬度。6.充填后牙邻面洞用的橘木尖,在市面上不 Stomatology often used a lot of small devices, sometimes due to poor quality or improper use is also easy to damage. We save, try to take renovation, renovation and other methods to make use of these wastes. Now bit by bit to introduce the experience of common research) 1. Denture sharp tip broken or curly shape, available grinding wheel or grindstone sharp change, roughly restore its original shape and then use. 2 digging, enamel chisel, scalpel working end can be damaged after the grinding wheel or grindstone tip into the original shape and then reuse, or grinding flat as a gingival separator, or modified into a single bevel tip as a root Tip out of the device, (apical) with. 3. The tip of the cotton tweezers is broken or curled, which can be corrected by the technician. At the same time, it can also be modified with a grinding wheel or a grinding stone tip. If the tip is damaged too much, from the joint of the forceps two arms off, divided into two, and then grinding the flat tip as a gingival separator. 4. Flush the root canal with a curved needle, waste needle can be used on the alcohol lamp flame burning red, curved into the use of appropriate camber. 5. Probe bending deformation, can be placed on the flame of alcohol lamp burn red (fire), with a mechanic clamp correction, restore its original shape, and then red and immediately immersed in cold water to restore its original hardness. 6. Filling the posterior face of the hole with the orange tip, not on the market
