Dewaxing Autoclaves--In support of net or near net investment casting, WSF Dewaxing Autoclaves are custom-designed to meet customers' production specifications.
In some cases, dewaxing by winterisation can also be required before bottling.
Xylene solution was used for dewaxing. The procedures for hematoxylin-eosin staining were as follows: hydration for 10 s with anhydrous ethanol, 95% ethanol, and 80% ethanol; wash with water for 2 min; hematoxylin staining for 8 min; wash with flowing water for 1 min; 1% hydrochloric acid ethanol for 5 s; wash with flowing water for 20 s; 1% eosin staining for 2 min; wash with water for 2 min; dehydration of gradient ethanol for 3 min; dehydration of xylene for 5 min; and seal with neutral gum.

Contaminants at the tooth-denture base interface such as wax, cold-mold seal, tin-foil substitutes and petroleum jelly also affects the bond strength significantly.1,11 Different studies indicated, the residual wax to be the principal contaminant responsible for adhesive failure.6,11,12 The reasons of improper wax elimination during acrylic denture processing includes greater surface roughness of acrylic teeth at RLSA4, low dewaxing temperature4 and ignoring the need of using wax removing solvent following dewaxing.4,12

The following steps were taken to prepare the specimens for study: (1) fixation: Specimens collected from the above patients were immersed in 10% formalin; (2) dehydration and clearing: Tissue samples were dehydrated gradually by graded ethanol (low to high concentration) and cleared in xylene; (3) paraffin embedding: Samples were embedded in paraffin and cooled to solidified blocks; (4) sectioning: The tissues were sectioned into 5–8 [micro]m sections and placed onto glass slides to dry in a 45[degrees]C incubator; and (5) dewaxing: Paraffin was removed by xylene, rehydrated in gradient ethanol (high to low concentration), and washed in distilled water.
