Abstract
Removable appliance should be considered as a method of interceptive orthodontic treatment and is mostly used in the mix dentition period. It basically either resolves the imminent dental problem or diminishes its severity. This is undoubtedly beneficial to the patient, in either way. However, since it is a patient-dependent, stability of the appliance in the place is very imperative. The stability is fulfilled by retentive clasps located on the appliance. This fulfillment has a substantial mechanical concept for designing. This article is a scrutiny on the retentive perspective of the appliance based upon principles of mechanics.
