A Non-Compliant Slow expansion devise in orthodontics: A case report on NiTi palatal expansion appliance.

Abstract

Normal palatal growth is nearly complete by age 6 and increasing inter-digitation of the suture makes separation difficult to achieve after puberty. Palatal expansion can be done with either slow/ rapid maxillary expansion. In this case report, maxillary expansion was done with NiTi palatal expander by making use of its unique properties like temperature transition and shape memory to produce an expansion of the maxilla. Keywords: NiTi palatal expansder, shape memory, temperature transition
