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.
Quotations are invited for Procurement of Dental Material for Dental Care Clinic, Hand held assorted endo preparation NITI files progressive taper, GP Points, Multilayered gold plated diamond points,
Modeling wax no.
* 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 were adopted.
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 (
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.
