Among the factors claimed to affect the retention of full dentures is the shape of the supporting structure. Parametric evaluation through the adaption of Fourier Analysis to the surface of maxillary edentulous jaw is described in this study. lt has been established that alteration in the cosine coefficient of the expanded equation affects both the right and left ridges symmetrically. Alteration of the sine coefficient affected the two sides of the ridge asymmetrically. The analysis furnished in this study will be necessary to study the relationship between jaw shape or the symmetry of such shape and the retention of full dentures.
