Impressions of the hand and legs of the donors were made using irreversible hydrocolloid impression material in the same manner explained above and modeling wax
was melted and poured into the impression material.
* The ability to mill a variety of non-proprietary materials, including acrylic, ABS, wood, and modeling wax
The modeling wax
results demonstrated that the removal process compromised the clarity of the resulting Sylgard tube.
At the laboratory, master models of both arches were prepared and occlusal wax rims were prepared using extra hard modeling wax
(TruwaxA Baseplate Wax, Dentsply Caulk, Milford, DE).
A ring of modeling wax
was built around the area to be recorded.
An impression was made of the mid facial region in irreversible hydrocolloid (alginate impression material) using modeling wax
sheets as the limiting boundaries.
On the cast a pattern was prepared in modeling wax
. Carving and finishing process was carried out on the model and surface texture of skin was incorporated using a brush (figure 4).
On the duplicated cast two sheets of modeling wax
prevented the denture from being placed too deep into the plaster.
MATERIALS: Cylindrical metallic die having 8mm diameter and 45mm length for the preparation of wax pattern, modeling wax
, elastomeric impression material (addition silicone putty consistency), dental stone type III gypsum product, type II gypsum product, silane treated E glass fibers
Then softened modeling wax
; Dental Products of India, Mumbai, India) with an approximate thickness of 3mm was adopted over the cast and the retentive clasps are added to the waxed up cast which was subsequently polymerized with heat cured acrylic resin ( DPI-Heat cure; Dental Products of India, Mumbai, India) by wax elimination technique.
