Title: Controlled lingual orthodontics with KommonBase
KommonBase is characterized by a large bonding base which can acquire the best fitting and a precise bracket position, and maximize bond strength. There is no need to use transfer trays because of its self-positioning shape. In addition, by using reference jig, brackets can be rebonded in case of bond failure and repositioning.
First generation of KommonBase has utilized flowable composite resin which was developed for restorative treatment, however, have potential risks for enamel fracture and discomfort on debonding. KommonBase require some features: more lower wear resistance, lower compression strength, and higher bond strength. Newly developed KommonBase resin supported above-mentioned features. Even in the case of occlusal interference, interfered resin can be ground automatically according to the function of occlusion. It is advisable to bond KommonBase with hybrid ionomer because the bond strength of hybrid ionomer is not affected by contamination of saliva and water. Furthermore, hybrid ionomer shows low film thickness, which lead to precise bracket position.
KommonBase also can be utilized unique appliance for the preparation of lingual orthodontics. In case of impacted upper canine, extruding canine followed by comprehensive treatment with only lingual brackets may be hard work. This appliance was enabling to control canine with three dimensions, which may make complicated case to simple case. Research-based bonding procedure and effective preparation will be presented for controlled lingual orthodontics.
