title: [The reliability of class A alginate impressions].
abstract: The class A alginates present very good properties of dimensional precision and reproduction of details, comparable to those of the reversible hydrocolloïdes and certain elastomeres used for the realization of secondary prints of precision in fixed prosthesis and in removable prosthesis. Besides, their application is easier and they are costless. The valorization of these print materials could certainly contribute to reduce the cost of comes back of prostheses in countries under developed where the weak power economic populations constitute a brake to the access to cares of health. To exploit qualities of these print biomaterials well, it agrees to manage correctly the parameters of their application. To this effect, the present survey puts in evidence that the maximum delay of stream that guarantees the good dimensional stability of these class A alginates is of 45 minutes in the hot and humid climatic tropical country conditions.
