Full Definition
PVS (polyvinyl siloxane), also called addition silicone or vinyl polysiloxane (VPS), is a dimensionally stable elastomeric material used to record tooth preparations, soft tissue, and implant positions for laboratory fabrication. It is noted for its excellent detail reproduction, low dimensional change, and ease of handling. Editors will encounter 'PVS' in materials sections of case reports, laboratory prescriptions, and product specifications. The abbreviations VPS (vinyl polysiloxane) and A-silicone are synonymous and may appear in the same document, requiring consistent editorial handling.
Usage
Usage note: On first use in a document, expand to 'polyvinyl siloxane (PVS).' Note that 'VPS' (vinyl polysiloxane) is an equivalent abbreviation; standardise to whichever form the author or house style prefers.
