Background

High speed turbine dental handpieces are required for cavity preparation in both dental preparation and caries treatment. Tooth preparation, in which a circle of tooth of a human body is polished for sleeving ceramic teeth. In the treatment of dental caries, a cavity is prepared, the cavity on the lingual surface of a tooth is cleaned, an opening is enlarged to enter the cavity, and when a marginal ridge is damaged, a small part of healthy tooth body tissue is ground to expose a lesion area.

The machine head of the high-speed turbine dental handpiece is provided with a machine needle, and the tooth body is ground through the high-speed rotation of the machine needle. However, the needle is very sharp and may hit the tongue to cut the tongue, which may cause infection or blood disease infection, especially when treating the teeth and tongue of the lower jaw, the tongue is easily cut.

The usual methods to overcome the above difficulties are: the dentist blocks the tongue with the odontoscope and does not let the tongue close to one end of the operation. However, this operation has the following problems: 1. when one hand is used for operating the high-speed turbine dental handpiece, the other hand is needed to block the tongue by using a dental mirror, and the operation is very troublesome. 2. In case the odontoscope does not fix the tongue, the tongue touches the machine needle, and the tongue is still cut.

To this end, we propose a stop tongue device for a high speed turbine dental handpiece to well address the above drawbacks.
