case_images: Five to six screw-like patterns were placed along the cameo surface of the custom trays as a guide for occlusion rim placement along the alveolar ridge, with an average tooth height of 4 mm and 10 mm for the posterior and anterior teeth, respectively (Figure 1(a)).

The posterior palatal seal was marked using a water-soluble colored pencil and transferred to the final impression, and flowable composite resin (Filtek  Supreme Flowable Restorative; 3M, Minnesota, USA) was directly applied onto the polymerized impression material without dental adhesive use (Figure 2(b)).

case_images: Because there was a discrepancy in the maxilla-mandibular relation, the occlusal surfaces of the maxillary posterior teeth were grinded with acrylic carbide burs and the maxilla-mandibular relation was rerecorded with Aluwax (Aluwax; ALUWAX DENTAL PRODUCTS CO., Michigan, USA) (Figure 3(a)). The final dentures were delivered at the fourth clinical appointment (Figure 3(b)).

case_images: At the second appointment, the duplicate dentures were tried in the patient's oral cavity (Figure 4(a)). The maxillary and mandibular final impressions were poured with type IV dental stone to fabricate the master casts, which were mounted on an articulator (Hanau  Modular Articulator; Whip Mix, Kentucky, USA) (Figure 4(b)). Notches were made on the land area of the master casts as an index for overlapping the tissue surface and tooth position after removing the duplicated denture (Figure 4(c)).
