Monofilament sutures:

  • Smooth and strong
  • Less chances of bacterial contamination
  • Knot tied may become loose

Polyfilament/Multifilament sutures:

  • Easier to handle and knot tied doesn’t slip
  • Bacteria may lodge in crevices of sutures – not suitable in presence of infection

Natural sutures:

  • Ingredient: Proteins
  • Degradation: Proteolysis
  • Strength distribution: Uneven
  • Inflammatory reaction: High
  • Absorption rate: Rapid

Synthetic sutures:

  • Ingredients: Copolymers
  • Degradation: Hydrolysis
  • Strength distribution: Even
  • Inflammatory reaction: Low
  • Absorption rate: Slow

Absorbability:
