TissueDB/Materials/Dental Impression Material
Dental impression material is an elastomeric material — commonly a vinyl polysiloxane supplied in light, medium and putty consistencies — used in dentistry to take impressions of the teeth and mouth. In surgical simulation it is used as a low-cost, quick-setting material: the softer light and medium consistencies give a rubbery, skin-like surface with acceptable resistance to a suture needle, while the stiff putty consistency forms a firm base.[1]

| Skin | Partial | Partial | Suturing Simulator (Kumaresan) | Light or medium elastomeric impression material forms the "skin" top layer of the suturing pad; its rubbery texture and tear strength simulate the elasticity and keratinised texture of skin and give acceptable resistance to a suture needle (Kumaresan et al. 2014).[1] |

Overview
[edit source]Dental impression materials are elastomeric materials, typically vinyl polysiloxane, that set within minutes at room temperature and are supplied in light, medium and putty consistencies. They are readily available in any dental institution. In simulation their quick set and rubbery, tear-resistant texture make the light and medium grades a low-cost skin analogue, while the putty grade serves as a firm base.
