Abstract
A technique has been described in which the form of the polished surfaces is developed in an impression paste at the try-in, and this form is carried through into the finished dentures. The polished surfaces of dentures are as important as the occlusal and impression surfaces in the construction of successful dentures. A method for determining the correct arch form and buccolingual position of the posterior teeth has been described. This position is called the neutral zone. A method of forming the contours of occlusion rims with soft modeling compound and establishing the vertical and centric relations by the swallowing method, and a procedure for developing and recording the smile line and the inclination of the anterior teeth has been described.
