Straight wire systems are effective in many orthodontic cases but not in
all ones because some unpredictable movements and side effects can
happen and in complex cases they can become really inefficient. We
will describe various custom-made orthodontic auxiliary devices very
useful to overcome the limits of straight wire systems.
This course includes theory-based training, clinical case presentations
and hands-on exercises on typodonts.Each lecture will be broken up
into an initial theoretical introduction and a subsequent practical
session.After the course participants will be able to simplify and solve
complex cases applying properly orthodontic biomechanics and how to
model and activate correctly auxiliary appliances for challenging
orthodontic movements.
We will learn how to manage properly difficult impacted
canines,transpositions and trasmigrations,asymmetrical cases,canting
of occlusal plane,incisors and molars intrusion without
miniscrews,canine and premolar root uprighting,huge
derotations,mesialization and distalization of posterior teeth, bodily
incisors advancement and retraction, palatal root torque correction of
ectopic teeth,molar uprighting with and without intrusion,”en masse”
extraction spaces closure.

Roberto Ciarlantini was born in Recanati(Italy) in 1964 and got his MSD degree with honors at Bologna University, in 1989. In 1992 he received his orthodontic education in Denmark,at Aarhus University , mentored by prof. Birte Melsen.He is a member of EOS,SIDO,SIBOS and AIOL.

He lectured nationally and internationally and published in various international orthodontic journals(American Journal of Orthodontics, Journal of Clinical Orthodontics,European Archive of Paediatric Dentistry, Orthopédie
Dentofaciale). He was reviewer of Seminars in Orthodontics.He is mentioned in American Board of Orthodontics Reading List since 2018.

He was awarded from Italian Orthodontic Society in 2006 and was finalist in 2012 at Young Chel Park Award during World Implant Orthodontic Congress in Sidney. He was the winner of Simply Ortho Case Contest in 2018. He was invited speaker at American Association of Orthodontists meeting in Atlanta in 2020.

His main fields of interest are biomechanics,skeletal anchorage, adult orthodontics and lingual orthodontics (he is certified in Incognito TM Lingual System and Alias TM Lingual System). He held courses on biomechanics both in Italy and abroad (Poland, Lithuania,Croatia.Bulgaria, Marocco,Denmark, Arab Emirates, Switzerland, Albania).He has a private practice limited to
orthodontics in Recanati(Italy) since 1991. Other information are available in the website www.studiociarlantini.it
