Guide Sleeves dictate the direction of the drill preparing the osteotomy. All inserts press fit into the guide sleeves to prevent spinning while drilling.
The surgeon (or assistant) will need to use the Insert Removal Tool to release the insert before placing the next larger size insert in a multi drill sequence. Inserts release easier when fabricated in an acrylic guide than if gripped between your fingers.
The use of the graduated size inserts for increasing drill sizes produces more accurate results. Inserts are available in 2.0mm - 4.6mm inside diameter increments and are compatible with the various drill sizes used with many implant systems.
Guide Sleeve Inserts are pressed down into a sleeve to obtain a press fit to prevent inserts from spinning while drilling.
