Dental extraction forceps commonly used on teeth in the maxillary arch. Extractions are often categorized as "simple" or "surgical". Simple extractions are performed on teeth that are visible in the mouth, usually with the patient under local anaesthetic, and require only the use of instruments to elevate and/or grasp the visible portion of the ...
The fulcrum is usually the crest of the socket bone; however, adjacent teeth can be used if they are also to be extracted. The contact point on the tooth or root surface where force is delivered is described as the purchase point, and the position of this can be idealised by cutting bone or sectioning teeth. With root picks especially, a slot ...

Accordingly, the nomenclature of surgical instruments follows certain patterns, such as a description of the action it performs (for example, scalpel, hemostat), the name of its inventor(s) (for example, the Kocher forceps), or a compound scientific name related to the kind of surgery (for example, a tracheotomy is a tool used to perform a ...
