Implant Removal Kit Instructions

This topic provides instructions on how to properly use the Implant Removal Kit, which helps remove failed implants without compromising surrounding bone or damaging neighboring structures.

Sterilize​ ​all​ ​needed​ ​components​ ​ before​ ​use.

Choose​ ​a​ ​Fixture​ ​Remover​ ​screw​ ​(FRS)​. ​3​ ​Screws​ ​are​ ​included​ ​with​ ​each​ ​kit and​ ​they​ ​are​ ​each​ ​designed​ ​to​ ​work​ ​with​ ​any​ ​threaded​ ​and​ ​self-tapping​ ​implant system.​ ​The​ ​fixture​ ​remover​ ​screws​ ​are​ ​available​ ​in​ ​small,​ ​medium,​ ​and​ ​large sizes.​ ​The​ ​small​ ​fixture​ ​removal​ ​screw​ ​is​ ​indicated​ ​for​ ​3mm-4mm​ ​diameter implants,​ ​the​ ​medium​ ​screw​ ​indicated​ ​for​ ​4mm​ ​-​ ​5mm​ ​diameter​ ​implants,​ ​and​ ​the larger​ ​screw​ ​is​ ​indicated​ ​for​ ​5mm​ ​-​ ​8mm​ ​diameter​ ​implants.​ ​Although ​ ​you​ ​can use​ ​the​ ​small-sized​ ​screw​ ​to​ ​remove​ ​large​ ​diameter​ ​implants​ ​(the​ ​screw​ ​will engage​ ​the​ ​implant),​ ​it​ ​may​ ​be​ ​difficult​ ​to​ ​disengage​ ​the​ ​implant​ ​from​ ​the​ ​screw after​ ​removal,​ ​when​ ​using​ ​a​ ​smaller​ ​screw​ ​for​ ​a​ ​larger​ ​implant.

Turn the Fixture Removal Screws Counterclockwise for Removal Counter-Clockwise​ ​Movement: Manually​ ​insert​ ​the​ ​Fixture​ ​Remover​ ​Screw​ ​in the​ ​implant​ ​thread,​ ​using​ ​the​ ​handle-adapter,​ ​ensuring​ ​it​ ​fits​ ​in​ ​a counter-clockwise​ ​direction.​ ​Connect​ ​the​ ​counter-torque​ ​remover​ ​wrench​ ​and turn​ ​it​ ​counter-clockwise.

Applying​ ​Torque:​​ ​Apply​ ​torque​ ​gently​ ​in​ ​an​ ​anti-clockwise​ ​direction​ ​until​ ​the implant​ ​is​ ​fully​ ​extracted.​ ​Note:​ ​Torque​ ​over​ ​200​ ​Ncm​ ​is​ ​not​ ​recommended,​ ​due to​ ​possible​ ​complications.​ ​If​ ​implant​ ​does​ ​not​ ​become​ ​mobile​ ​at​ ​200​ ​Ncm,​ ​use optional​ ​trephine​ ​technique​ ​as​ ​per​ ​below.

Optional​ ​Trephines:​​ ​Some​ ​patients​ ​experience​ ​pain​ ​under​ ​high​ ​reverse​ ​drive, and​ ​some​ ​implants​ ​may​ ​require​ ​these​ ​high​ ​torques​ ​for​ ​removal.​ ​In​ ​these​ ​rare cases,​ ​trephines​ ​are​ ​used​ ​in​ ​combination​ ​with​ ​the​ ​FRS​ ​(​see​ ​Froum​ ​S, Compendium.​ ​2011;32(7):2-24)​.​ ​Trephine​ ​drilling​ ​to​ ​just​ ​2-3mm​ ​reduces maximum​ ​torque​ ​to​ ​less​ ​than​ ​half,​ ​to​ ​break​ ​the​ ​implant-bone​ ​connection​ ​with extraction​ ​success.​ ​However,​ ​do​ ​NOT​ ​use​ ​the​ ​trephines​ ​all​ ​the​ ​way​ ​to​ ​the​ ​end​ ​of the​ ​implant.​ ​Instead,​ ​use​ ​the​ ​trephines​ ​for​ ​1/2​ ​or​ ​1/3​ ​(just​ ​2-3mm)​ ​and​ ​then​ ​use the​ ​specialized​ ​fixture​ ​remover​ ​screws​ ​and​ ​​​reverse​ ​remover​ ​wrench,​ ​as​ ​per above,​ ​to​ ​remove​ ​the​ ​rest​ ​of​ ​the​ ​implant.

Removing the Removal Screws after Extraction

It’s important to remember that the implant are removed using Counter-Clockwise​ ​Movement! So you would manually insert the Fixture Remover Screw in the implant thread, using the handle-adapter, ensuring it fits in a counter-clockwise direction. Connect the counter-torque remover wrench and turn it counter-clockwise.

The video below, shows how to remove the screws from the implant after it is extracted. It is important to remember that when you used the implant remover screws to remove the implant, you reverse torqued into the implant, by turning counterclockwise. So to remove the remover screw from the implant, you must remove it by turning CLOCKWISE. Use a wrench to help with removal, as the screw will be tightly engaged with the implant.

(Note: This video is for an implant removal screw from the Gen2 Kit, but it is the same concept for the removal screws from the MCT Bio kit, as both screws function in the same manner).
