In general, removable orthodontic appliances fall in the category of interceptive orthodontic treatment and are mostly used in mixed dentition period. Basically, they can either resolve dental mal alignment or diminish its severity(¹). Either way, this is definitely beneficial to the patient. However, this is a patient-dependent protocol and stability of the appliance in place is vital(2). Both the active tooth movements and the stability of the appliance are accomp/lished mainly by active components (springs) and retentive components (clasps) attached to the appliance respectively. Fulfillment of the treatment objectives requires a substantial mechanical concept and robust design.
