The choice of instruments depends on the correct choice of scaler according to the treatment site. Sickle scalers are different in size and shape and neck design, and are used in different parts of the mouth.
For front teeth: there are right-angle scalers and sickle scalers. Its working end, neck and handle are on the same plane.
For posterior teeth: curved sickle-shaped dental scalers are paired, and their necks form a certain angle, so that the working end can adapt to the shape of posterior teeth. Because its 44 degree is like a horn, it is also called a horn-shaped dental scaler. Use one of the paired instruments on the buccal side and lingual side respectively. The key to selection is that the working surface of the instrument can form an angle of 80 with the tooth surface when it is used. Sickle scaler can also be used for posterior teeth scaling. Pigments on the buccal and lingual surfaces of the posterior teeth can also be removed by a pair of hoe-shaped dental cleaners.
Introduction:
Scaling is an important means to remove dental calculus and plaque and prevent and control the occurrence and development of periodontal disease. The instruments used in clinical scaling are mainly ultrasonic scalers. The types of ultrasonic scalers vary from manufacturer to manufacturer, but their working principles are basically the same, that is, the host sends out oscillation and transmits it to the working head through the mobile phone, and the working head generates oscillation to remove the stones attached to the tooth surface!
