Description
技术领域technical field
本实用新型涉及口腔医疗器械，尤其涉及一种柔性根管塑形器械。The utility model relates to an oral medical instrument, in particular to a flexible root canal shaping instrument.
背景技术Background technique
根管治疗是目前治疗各种牙髓炎、牙髓坏死、牙齿折断等疾病比较理想和成熟的治疗方法。根管治疗一般分为五个主要步骤；术前的诊断、冠部的准备和预备、根管的塑形和清洁（预备和冲洗）、根管的充填和检查、冠方封闭及复查。其中根管的塑形和清洁，是利用根管锉等器械对病变根管内部和根管壁进行彻底清理，去除病变组织，塑造出完整、光滑的根管内腔，然后在已成型的根管内填充其他材料，如牙胶尖等，以达到根管修复和治疗的目的。Root canal therapy is an ideal and mature treatment method for various pulpitis, pulp necrosis, tooth fracture and other diseases. Root canal treatment is generally divided into five main steps; preoperative diagnosis, crown preparation and preparation, root canal shaping and cleaning (preparation and irrigation), root canal filling and inspection, coronal sealing and review. Among them, the shaping and cleaning of the root canal is to thoroughly clean the inside of the diseased root canal and the root canal wall with instruments such as root canal files, remove the diseased tissue, and shape a complete and smooth root canal cavity. The canal is filled with other materials, such as gutta-percha, to achieve the purpose of root canal restoration and treatment.
根管塑形是利用根管锉等器械，机械式完成根管腔的塑造过程。目前临床使用的根管锉均采用金属材料制成，如不锈钢和镍钛合金。金属根管锉的工作部上分布有螺旋状切削刃，外轮廓有一定的锥度，如图1所示。工作时根管锉是以一定的转速在根管内做旋转运动，利用切削刃去除根管内表面感染组织，以达到根管塑形的目的，如图2所示。Root canal shaping is the use of root canal files and other instruments to mechanically complete the shaping process of the root canal cavity. The root canal files currently in clinical use are all made of metal materials, such as stainless steel and nickel-titanium alloys. There are helical cutting edges distributed on the working part of the metal root canal file, and the outer contour has a certain taper, as shown in Figure 1. When working, the root canal file rotates in the root canal at a certain speed, and uses the cutting edge to remove the infected tissue on the inner surface of the root canal to achieve the purpose of root canal shaping, as shown in Figure 2.
由于传统金属材料制成的根管锉刚度大、弹性差，且有一定的锥度，又由于根管一般呈弯曲状，所以金属根管锉要实现对根管底部的清理与塑形，往往需要在根管上段预备出较大尺寸和大锥度的过渡段。这些因素将导致使用金属根管锉预备成型的根管直径较大，在根管成型时会有大量无感染的牙本质组织被切削去除。Because root canal files made of traditional metal materials have high rigidity, poor elasticity, and a certain taper, and because root canals are generally curved, metal root canal files often need to be cleaned and shaped at the bottom of the root canal. A transition section with a larger size and a larger taper is prepared in the upper part of the root canal. These factors will lead to a larger diameter of the root canal prepared with the metal root canal file, and a large amount of non-infected dentin tissue will be cut and removed during root canal shaping.
最新的研究认为，根管治疗的目的是修复和保留已被感染的牙齿，并使其能继续长久地发挥使用功能；而过多的牙本质去除，会严重影响治疗后牙齿的使用寿命，导致治疗后的牙根管过早的发生开裂，过早地失去使用功能，这是与根管治疗的目的相违背的。如何在根管治疗时尽可能地少去除无感染牙本质组织，成为了目前根管治疗牙科学所关注的焦点。According to the latest research, the purpose of root canal treatment is to restore and preserve the infected tooth, and to enable it to continue to function for a long time; however, excessive dentin removal will seriously affect the service life of the tooth after treatment, resulting in The treated root canal cracks prematurely and loses its function prematurely, which is contrary to the purpose of root canal treatment. How to remove as little non-infected dentin tissue as possible during root canal treatment has become the focus of current root canal treatment dentistry.
