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.‏
