Broken instrument retrieval with indirect ultrasonics in a primary molar

European Archives of Paediatric Dentistry, 2015
The separation of a file during pulpectomy is a rare incident in primary teeth due to inherently wider and relatively straighter root canals. A broken instrument hinders the clinician from optimal preparation and obturation of the root canal system invariably leading to failure, although in such teeth, an extraction followed by suitable space ...

The effect of the apical dentinal plug on broken endodontic instruments

Journal of Endodontics, 1979
This study was concerned with the leakage that occurs around broken endodontic instruments when they are left in the apical third of the root canal. Dissociated single-rooted human teeth were used after the crowns were removed. One hundred specimens were prepared by filing and filling according to accepted clinical standards, except that various sizes ...

Failure analysis of broken pedicle screws on spinal instrumentation

Medical Engineering & Physics, 2005
Revised spinal surgery is needed when there is a broken pedicle screw in the patient. This study investigated the pedicle screw breakage by conducting retrieval analyses of broken pedicle screws from 16 patients clinically and by performing stress analyses in the posterolateral fusion computationally using finite element (FE) models.

Instrument Set for Removal of Broken Screws

1981
In the united fracture, a broken screw is usually well tolerated for a long period of time. The bone damage resulting from the heat generated by reaming out the screw fragment can be considerable. For this reason, a broken screw should be removed only if this is possible without extensive bone damage.

A method for the removal of broken endodontic instruments from root canals

Journal of Endodontics, 1983
In this study, a different armamentarium for the removal of fractured endodontic instruments from tapered root canals was used. The advantages of the method in comparison with conventional techniques are discussed.

An intraoperative method of localizing a missing piece of a broken laparoscopic instrument

American Journal of Obstetrics and Gynecology, 1997
Missing a laparoscopic needle or a dislodged broken piece of a laparoscopic instrument presents a challenge in localizing it. A fragment of a broken instrument is often confined in an area remote from the primary operative side and entrapped in the bowel loop or in the omentum.

Modified Usage of the Masserann Kit for Removing Intracanal Broken Instruments

Journal of Endodontics, 2003
The Masserann kit is a hollow tube device specially designed for the removal of intracanal metallic objects. This report describes some modifications in the usage of this device for effective removal of tightly bound intracanal broken instruments whose diameter is relatively large at the coronal end.
