Black Gum is a novel thermoreversible polymer both for duplications in all types of investments ( including phosphate-bonded ones) and in gypsum and for the creation of full or partial dentures.

Black Gum can be melted both in duplicating machines and in microwave ovens. Black Gum is a liquid between 95 °C (203 °F) and 50 °C (122 °F) and an elastic, but tough gum under 40 °C (104 °F).

Its high tear resistance and optimal hardness allows a single Black Gum mold to be remelted more than 40 times without losing its technical features and to be used for many successive duplications.

Remelting the same mold more than 40 times allows to reduce duplication costs by at least 99 % when compared with silicone : 1 Kg of Black Gum = 40 Kg of liquid addition silicone.

Black Gum is more precise and more accurate than the duplicating gel and the RTV addition silicone:

Acrylic resin casting

Black Gum is poured insed the specific flask. Mold made in Black Gum with all teeth ac-curately settled.

The resin is poured into the flask contain-ing the mold made in Black Gum.

Denture ready to be delivered.

Duplications in phosphate-bonded investment ; duplications in gypsum

Black Gum is poured into the flask and on the master model.

Our phosphate-bonded investment Framevest is poured into the Black Gum mold.

Final work. Note both the accurate reproduction of the space between the lingual bar and the mucous membrane (created with a 0.3 mm calibrated wax) and the tight fit of both the model to the occlusal rest and of the clasps to the teeth.
