Materials Used for Border Molding: low fusing compound with putty consistency
Final Impression: representation of the completed registration of a dental surface or object, also called master impression
Materials Used for Final Impression: Zinc Oxide Eugenol Impression Paste and Elastomeric Impression Materials
Definitive Cast: replica of residual ridge areas or other parts of the dental arch used to fabricate a prosthesis
Making Final Casts: methods include Alpha hemihydrate (dental stone), Inversion Method (for preliminary casts), and Beading and boxing method (for master casts)
Wax boxing Method: creating a container for the impression using wax and plaster or pumice
Maxillary Impression: applying wax, creating lands using beading wax or plaster and pumice, and pouring yellow stone into the impression
Mandibular Impression: applying rubber base adhesive or hot sticky wax, creating lands using red beading wax or plaster and pumice, and pouring yellow stone into the impression
Pouring the Cast: preparing a mixture of yellow stone and carefully pouring it into the impression
Retrieving the Cast: separating the cast from the impression after heating it in a water bath
Trimming the Cast: flattening the base, trimming the sides, and reducing the depth of the peripheral roll
