Anterior open bite correction with hybrid FLOWJAC® system devices, patient with previous Chin bone resorption. Case report.


The orthodontic minitubes system (FLOWJAC ® System, Bogotá, Colombia) is an innovating system that blend the selfligating philosophy techniques and a lowprofile appliance. The FLOWJAC® System works with low orthodontic forces, same as selfligation devices. The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi. The clinician in each appointment must modify the minitube location to the clinical desire teeth position. The present report blend FLOWJAC® devices in the upper arch and clear selfligation in the lower arch. The patient treated has mandibular bone resorption due a alloplastic chin augmentation. The root apex from first right premolar to the first left premolar seen to be near to the resorption area using Cone Beam Computer Tomography. That´s the reason why we use a pre-adjust devices in the lower arch, to avoid pulpar and periodontal counter effects. This case was finished with proper functional and aesthetics objectives; such as molar and canine class I, anterior open bite closure with 20% of overbite, coincidence of dental smile arch with lower lip, and without root and pulpar counter effects. The porpoise of this report is to present an orthodontic case with bone resorption on right premolar and incisors area of the mandible. The case was treated with selfligation orthodontics system; FLOWJAC® System in the upper arch and Empower Clear® (American Orthodontics Shebboyiang, USA) in the lower arch and could be done with a precise diagnosis and adequate treatment planning.
