    Exploring Tooth Movement – The Hycon Precept
    Written by: Dr. Winfried Schütz
Fig. 1: The Hycon is inserted in the lower jaw. The patient was told to turn the Hycon 2x 1/2 turn per week. Additionally he had to wear Class III elastics blue heavy from 26 to 33 during the nighttime.
Fig. 2: State of treatment after the Hycon has worked 3/4 of its range. The Hycon is reactivated, activation order/ intermax. as before.
Fig. 3a: The Hycon has worked another 3/4 of its range. The space in the the lower jaw has become significantly smaller, the overjet and the midline shift are improved. Time has come also to install the Hycons in the upper jaw. All the three Hycons have to be activated simultaneously 2x 1/2 a turn per week, class III elastics to be continued.
Fig. 3b, 3c: Occlusal view of same state.
Fig. 4: State of treatment about four weeks later.
Fig. 5a/ 5b: After another 3/4 range action of the Hycon, space closure is carried out. The midline is correct.
The bolts of the Hycon are removed. Now the occlusion has to be adjusted, finishing has to be done.

HYCON™ DEVICE - Fast, easy and precise space closure

 Picture



​


Controlled, predictable, safe and successful space closure was our aim, and the simple mechanics of a screw was the answer.  The movement of the tooth is determined solely by the advancement of the thread of the screw.  The thread has been precisely engineered to a pitch of 0.014”, now you can calculate this pitch by the number of turns to precisely advance the screw and close spaces with complete success.
“ When I started working as an orthodontist, I was not sure of the force generated by my closing loops. I was concerned about the periodontium tissue. The idea to close the space by means of screw mechanics eased my mind. Since 1984 all my space closing has been done by the Hycon - it has never failed me. Sometimes my colleagues tell me, they are able to treat cases with the Hycon device, that before would have been beyond therapy. This is especially important for the periodontal compromised adult patients.“
