Abstract

Abstract A taxidermic specimen and a method of formation thereof is disclosed. A preliminary negative mold (28) is formed by applying an alginate material to the jaw structure of the animal carcass. Fibers (50) are disposed within the depressions (30, 32 and 34) to provide tooth stains. Tooth-colored acrylic material is alternately poured in layers into the teeth depressions (30, 32 and 34) of the preliminary mold (28). The hardened acrylic teeth (44, 46, 48) are removed and chamfered around the gingival line (40). The teeth are reinserted into the preliminary mold (28) and covered by palate and gum forming fiberglass. Natural appearing colorations are provided comprising selected colored threads (52) near the surface of the gum structure. The composite tooth, gum and palate structure forms the master mold (54). From the master mold (54) a final rubber production mold is formed which is used to construct additional production taxidermic specimens in the same manner in which the master mold (54) was formed.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 99 words
A method of fabricating a specimen of a body part, comprising the steps of: forming a preliminary mold having a negative impression of the body part; forming a master mold using the preliminary mold, and forming said master mold as a replica of said body part having substantially all the color and contour characteristics of the body part; forming a final negative impression mold using said master mold; and forming a plurality of specimens of the body part using the final negative mold and forming said specimens in accordance with the color and contour characteristics of said master mold.
Claim 2
Independent Claim 99 words
A method of fabricating a specimen of a body part, comprising the steps of: forming a preliminary mold having a negative impression of the body part; forming a master mold using the preliminary mold, and forming said master mold as a replica of said body part having substantially all the color and contour characteristics of the body part; forming a final negative impression mold using said master mold; and forming a plurality of specimens of the body part using the final negative mold and forming said specimens in accordance with the color and contour characteristics of said master mold.
Claim 3
Dependent Claim 15 words
The method of claim 1 wherein the preliminary mold is formed using an alginate material.
Claim 4
Dependent Claim 31 words
The method of claim 1 wherein the final negative mold is formed by pouring a liquified rubber over sadi master mold, and allowing the rubber to cure to a resilient state.
Claim 5
Dependent Claim 39 words
The method of claim 1 further including forming said master mold using a colored acrylic material and an epoxy material, and forming said specimen substantially identical to said master mold using a colored acrylic material and an epoxy material.
Claim 6
Dependent Claim 31 words
The method of claim 4 further including forming a jaw part by forming the teeth thereof with the colored acrylic, and forming the palate and gum material with the epoxy material.
Claim 7
Dependent Claim 17 words
The method of claim 1 further including freezing the body part before forming the preliminary mold therefrom.
