COURSE OUTLINE
Abutment and prosthetic screw fractures have become increasingly a common place due to the increasing use of third party manufacturers and to the mix and matching of various systems that claim cross compatibility. Even labs have started to outsource many of the abutments and the screw tolerances are not being evaluated. In addition passivity of frameworks and restorations seem to be overlooked with avoidance of verification jigs and trial prosthesis. The increasing use of full arch restorations necessitates use of prosthetic screws over multi unit abutments. This has led to increasing number of screw fractures and loosening. This course will illustrate step by step removal of broken screws from implants and retrieval of screw fragments within the implants. When the abutment screw assembly is quite rigid and when there is an overload, implants may sometimes fracture or the crest module that supports the prosthesis could flower. The only option in the past to remove fractured implants was to trephine these implants out. The technique of removing fractured implants in an atraumatic manner will be illustrated with videos and step-by-step demonstration.
 
LEARNING OBJECTIVES
To recognize screw fractures and stripped screws and identify the cause of these occurrences.
To create a plan to retrieve and remove broken abutment and prosthetic screws
To illustrate the use of  the Screw removal kit
The removal of any fractured implant either at the crest module  level  or at the body level of implants.
To learn the atraumatic way to remove fractured implants.
How to place implants immediately after removal of fractured implants.
