Changing the dynamics of alveolar molding using a modified single cantilever spring

Abstract

Deviated premaxillary segment commonly seen in bilateral cleft lip and palate causes difficulty during surgical procedures. Modifications in the conventional feeding plate appliance design by incorporation of a single cantilever spring can enable shifting of the deviated premaxillary segment and facilitate alveolar molding. Thus reducing the tissue tension and in turn preventing the prospect of further scarring which can have severe detrimental effects on maxillary growth and as a result aid in achieving better surgical outcome on lip closure.This article presents a case of a 27 day old infant with a deviated premaxilla which was repositioned for better retraction using a modified cantilever spring design in the molding plate. Reduction in cleft gap while shifting of the premaxillary segment on the right side was seen after full time wear of only 5-6 weeks.
