ABSTRACT

Extractions are a recurrent dental surgical procedure. Occasionally, tooth extraction is not easy, and there is the possibility of several complications, including the fracture and migration of instruments, especially during surgery of third molars. Such conditions can be triggered by several factors, such as defective manufacturing, stress, fatigue, rust, poor handling, and the use of worn burs or inadequate irrigation. The aim of the present review is to discuss the fracture of the surgical bur Zekrya, mainly associated with the lower third molar section. Sometimes, fragments of burs not seen during the surgery can cause complications, such as discomfort and infection after the procedure. Metal fragments left in situ can also be encapsulated by fibrous tissue and gain access to adjacent spaces when recognized by the host as a foreign body. Breakage of any instrument implies searching for the fractured fragment and removing it since the trapped foreign body material is also capable of affecting the nerve and causing paroxysmal pain, continuous pain, or paresthesia, which can be felt in the nerve distribution area. According to the ethical code, if an unexpected accident occurs during the surgical procedure, such as the fracture of the instruments mentioned above, the patient must be informed, and the necessary measures must be taken to solve the problem.
