Saline or silicone gel implants are another option. In some cases, an implant is added after autologous reconstruction. A study done by researchers at the University of Texas MD Anderson Cancer Center suggests that silicone breast implants are associated with a higher risk of certain autoimmune disorders, as well as stillbirth and melanoma.
The difference between impression materials
Silicone impression material consists of a base and alyst in a putty consistency. Silicone impressions are classified according to their method of polymerisation on setting. They are available in a range of viscosities including light, medium, heavy and very high viscosity (or putty) material.
Silicone Sealant vs Acrylic Sealant | …
Silicone sealants are more flexible and have a longer lifespan than acrylic sealants. In addition when applied externally acrylic sealants are ruled by the climate, conditions must be dry and preferably warm to avoid the curing sealant being washed out of the joint.

Choisir un Mastic : Silicone, Polyuréthane (PU), MS …
Contrairement au silicone, l’acrylique est inodore et peut être peint. Plusieurs couches peuvent en outre être superposées. L’acrylique est toutefois moins adhérent et moins élastique que le silicone et il n’est que partiellement hydrofuge, de sorte qu’un mastic silicone est préférable dans les pièces humides.
