The innovation

rootEX® instruments enable fast and efficient extraction of root fragments without additional surgical intervention thus avoiding weakening of the jaw bone.
Pre-drilling cleans and opens a hole enabling the retentive plug to be pressed into the root fragment. Unlike conventional tools, which are screwed into the root fragment, pre-drilling and subsequent pressing prevents the rootEX® root tip extractor from being overtightened and thus further breakage.
As soon as the plug is pressed deep enough into the fragment, the retentive elements of the rootEX® plugs connect with the root fragment. This allows for safe extraction of the fragmented root from the socket in one piece. For simple cases, a one-step system is also available in which the retentive elements are applied directly onto the drill.

2 Steps Procedure

Step 1

Perforating the root fragment using the rootEX® drill at the lowest possible speed (contra-angle handpiece). The rootEX® drills are sterilizable and can be used several times.

Step 2

The corresponding plug is pressed into the predrilled hole with a slight clockwise rotation. The laser-milled retentive barbs generate an extractive force of over 80 N, which exerts sufficient grip to remove the root fragment. The rootEX® plugs are suitable for single use only, as the retentive barbs do not develop sufficient extractive strength after inital use. The specially developed rootEX® forceps can be used if root fragments remain stuck.

One-step rootEX® system

For simple cases, a one-step rootEX® system is also available, in which the retentive barbs have already been laser-milled onto the drill so that the root fragment can be pulled directly after drilling. Slight tilting (pulling force slightly angled in relation to the drill hole) increases the adhesive force of the instrument. If the root fragment is firmly anchored, the extraction can be performed using the rootEX® forceps (to loosen the desmodontium, it is recommended to allow some time for this procedure).
