Wing Bib Multihelix Maxillary Expander (Patent 422140) is a maxillary expansion appliance to increase the width of the palate at its anterolateral slopes, including the depths, by bone remodeling. The idea is that if space is needed in the cuspid- first bicuspid region chiefly to accommodate their roots during alignment, a direct force projecting out at the cuspid- first bicuspid root area should do the needful. A force which is perpendicular, not to the mid-palatine raphe but to the bony surface covering the cuspid- first bicuspid roots. Such force which falls at the anterolateral slopes of the palatal vault at its depth to attempt bone remodeling in the area. A force free, i.e, independent of any other anterior midline attachment to eliminate any interference to its action.
The posterior part can be activated laterally as well as distally to move the expanding maxillary arch in the distal direction during alignment and eliminate proclination of the anterior segment.
Another feature is a braking mechanism between the anterior and posterior active portions to keep the anterior and posterior activations separate and titrable.
Wing Bib MME has three parts
Anterior active part consisting of the laterally positioned Wing bibs
Intermediate helical assembly consisting of a wire assembly connecting respective lateraly positioned the anterior active parts (Wing Bibs) to the posterior active part
The posterior active part consisting of a wire formation connecting the lateral parts and only part of the appliance crossing the palatal midline
Wing Bib MME is a slow maxillary expansion appliance made from a beta- titanium wire, provides light continuous forces and flexibility of adjustments.
