Suture materials are classified as either resorbable (absorbable) or non-resorbable (non-absorbable).

Non-resorbable sutures are made of materials that are not broken down by the body's tissues and remain in place until manually removed or permanently integrated.

Polypropylene is a synthetic, monofilament, non-resorbable material known for its low tissue reactivity and strength.

Resorbable sutures are designed to be absorbed by the body over time.

Polyglactin 910 (Vicryl) is a synthetic, braided, resorbable suture.

Catgut is a natural, resorbable suture derived from purified collagen.

Polyglycolic acid (Dexon) is also a synthetic, resorbable suture.

• Diatomaceous earth (an inert filler) is the largest component of alginate impression material by weight percentage. It makes up approximately 60% of the material.
• Potassium alginate (the reactive component) is the next largest component, usually around 15-20%.
• Calcium sulfate (the reactor) and sodium phosphate (the retarder) are present in smaller quantities.
