Management of impinging “Nickel titanium palatal expander” in cleft palate cases by “Soft flow” (temporary mucosal protector)

The temperature-activated Arndt nickel titanium palatal expander has been a good choice for cleft palate applications because it creates transverse maxillary expansion, uprights and rotates the maxillary molars, and allows a smooth transition to fixed retention with no requirement for patient compliance and little manipulation by the clinician. But the clinical problem sometimes encountered is the impinging of “Nickel-Titanium” metal component of the Nickel titanium palatal expander on the soft palate. “Soft Flow” is a Temporary Mucosal Protector introduced recently in the orthodontic market which prevents the impinging of micro- implants or hooks of the molar buccal tubes. The following article highlights the clinical problem encountered after placement of Nickel Titanium Palatal Expander and how “Soft Flow” helps to overcome it.
