A moldable dressing for facial skin grafting: polysiloxane.

Impression materials are used in the various phases of denture construction, and polysiloxane is one of the elastic impression materials, which are also known as ‘‘condensation-cured (condensation-reaction) silicones.’’ These products are manufactured in a wide spectrum by different companies (e.g., Kerr, 3M/ESPE, Dentsply Caulk, Ivoclar Vivadent) and have interesting physical characteristics. Polysiloxane is a low-viscosity liquid and when mixed with a catalyzer (metallic organic ester) it solidifies within a few minutes and transforms into elastic form. Once polysiloxane is elastic, its consistency resembles a silicon gel sheet. This new form is available also for new shaping procedures, and this feature is attractive to users (Figure 1). In the presented study, polysiloxane was used for the fixation of facial skin grafts.
