Apicoectomy
A Root End Surgery, also known as "apicoectomy" (L. apex, apicis: a summit or a tip), is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material. This is usually necessitated when a conventional root canal therapy had failed and a re-treatment was already unsuccessful or is not advised. State of the art procedures make use of microsurgical techniques, such as a dental operating microscope, micro instruments, ultrasonic preparation tips and calcium-silicate based filling materials.
