    Abstract:
    The insertion and removal of an obturator in large maxillary defects with or without trismus is difficult. Fabrication of a two-piece obturator in such cases overcomes this problem. This article describes rehabilitation of large maxillary defects with two piece maxillary obturator of three types. All these obturators have a maxillary plate and a bulb component, which are approximated together by various techniques namely, silicone cover, embedded magnets, and press studs. Prosthetic rehabilitation of large maxillary defects with two-piece obturators offers the possibility of adequate oral rehabilitation by fabricating light weight prosthesis, which is easy to use. The bulb covers the undercut areas of the defect enhancing the facial contour and retention. It facilitates easy examination of underlying tissues, recreation of the anatomic barrier between the oral and nasal cavities and restoration of the function and esthetics. Thus, it adds to the quality of life.
