The biomechanics of Kansal Separator: A ‘2 in 1’ self-secured orthodontic spring separator

BACKGROUND: An important stage at the very beginning of orthodontic therapy is the separation of teeth where space is created for banding of the molars. A dislodged separator may create problems if ingested or it may get wedged between the adjacent teeth causing acute localized periodontitis. In order to overcome these shortcomings of conventional separators, the Kansal Separator was conceptualized. This separator has been designed as a single device that acts simultaneously on both mesial and distal aspects of tooth, causing adequate separation. In addition to separator's independent 2 in 1 action, the self-locking connecting bar prevents the premature dislodgement of the separator. AIM: To determine the force vectors produced by Kansal separator. MATERIALS AND METHODS: A prototype model was created to study the forces produced. RESULTS: The separator's unique design is based on sound biomechanical principles that explicate the proof of concept and allows the separator to be distinctly effective and efficient in variable clinical situations, thus amplifying its uniqueness. DISCUSSION: The Kansal Separator, a 2 in 1 orthodontic tooth separator, has a unique design enabling the device to simultaneously separate the teeth on the mesial and distal aspect of the tooth to be banded. CONCLUSION: Kansal Separator's unique design is based on sound biomechanical principles that explicate the proof of concept and allows the separator to be distinctly effective and efficient in variable clinical situations, thus amplifying its uniqueness.
