Duplicatable maxillary denture materials, e.g., partial or complete dentures, wax-ups and bite blocks, are prepared employing the relator assembly and process of the invention. The process involves forming the maxillary denture materials from a rough maxillary cast of the patient's mouth that has a base and an expression of the maxillary alveolar ridge including the anterior palatine papilla and hamular notches. In the process, the cast is suspended over a horizontally extending, flat occlusal base member at a predetermined height corresponding to the proposed incisal length of the denture materials with members of substantially equal height, located on the occlusal table, that contact the cast at the palatine papilla and hamular notches. The base of the suspended rough cast is luted to a maxillary base member that is located over and substantially parallel to the occlusal base member to form a cast whose base is parallel to the hamular-incise plane. Thereafter denture elements, individual artificial teeth or bite-block elements are arranged on the occlusal base member in a predetermined location relative to the cast luted to the maxillary base member and corresponding to the proposed labial drape of the patient. The aforesaid denture elements, individual teeth or bite-block elements are then luted to the alveolar ridge of the cast mounted on the maxillary base member.
