15Internal 3 Dental Equipment Fixation & Instrumentation Insert Sleeves Countersinks If the screw is destined to screw down onto the surface of the bone without a plate, it is helpful to contour the top of the screw hole to fit the screw head. This procedure is especially important when lag screwing relatively small fragments. Failure to countersink may lead to fracture of the bone fragment. Our premium countersinks provide best fit to screw head when using AO type screws. Drill Sleeves centre smaller drills in the placement of lag screws.

Use of tissue protection sleeves minimises such damage. The teeth at the top of the guide locate on the bone whilst the stainless tube provides a barrier between soft tissue and implant equipment.

A more reasonably priced option is to use a drill stop which is tightened onto the drill bit at the required depth. The Set includes 4 Stops to cover all the standard drill sizes. Premium Countersinks The drawbacks of using standard countersinks is that cone shaped recesses are created that only allow point contact with the hemi-spherical underside of AO type screw. This may contribute to premature screw loosening and in some cases the wedge effect created may predispose to split propagation from the hole. Optimal screw stability and force transfer is only achieved if the shape of the countersink recess matches the size and shape of the screw-head. This is achieved with our range of premium countersinks. Available only with AO quick release coupling. 2.0, 2.5, 2.7, 3.2, 3.5 & 4.5mm The stop is tightened onto the drill bit using the hex driver provided.
