Prosthodontic principles in the framework design of maxillary obturator prostheses.
The Aramany classification system of postsurgical maxillectomy defects is a useful tool for teaching and developing obturator framework designs and enhancing communication among prosthodontists. This article describes a series of Aramany-obturator design templates and discusses the relevant considerations for each. In all situations, a quadrilateral or tripodal design is favored over a linear design because this allows a more favorable leverage design application that will aid in the support, stabilization, and retention of the prosthesis.
