The Tudor-Edwards retractor is an instrument for expanding the oral cavity and introducing various medical instruments into the oral cavity during dental operations. It was developed by American dentist William Tudor and his colleague Edward Edwards in 1911.
The Tudor-Edwards retractor consists of two parts: a handle and a working part. The handle is shaped like a pistol and has several finger holes. The working part consists of four parts: a base, two levers and a movable blade. The base is crescent shaped and is attached to the handle. The levers are shaped like hooks and are connected to the base and blade. The blade is shaped like a semicircle and can move up and down.
The principle of operation of the Tudor-Edwards retractor is that it allows you to expand the oral cavity and introduce various medical instruments into the oral cavity. At the same time, thanks to the movable blade, you can adjust the width of the opening of the oral cavity.
This instrument is used in various dental procedures such as tooth extraction, denture installation, gum disease treatment, etc. It is also used for oral surgery such as implant placement, tumor removal, etc.
One of the advantages of the Tudor-Edwards retractor is its safety. It allows the dentist to control the width of the patient's mouth opening and avoid tissue damage. Additionally, this instrument can be used to perform a variety of procedures at different levels of the mouth, making it a versatile tool for dentists.
