SUTURE

• Needle – 3/8th curved, reverse cutting edge is commonly used in dentistry for perio, surgical extraction etc.
• Needle should be held at 2/3rd from the tip or 1/3rd from the eyelet
• In 3rd M surgery, most commonly used needle holder intra orally — curved hemostat or artery forceps

SUTUTRE MATERIALS:-

• Most commonly used material intra orally — 3.0 black braided silk

Resorbable
Eg: Catgut – 8 days
      o Shouldn’t sterilize in autoclave because cattle protein will get denatured
      o Sterilize using 70% isopropyl alcohol
         ◾ Best % /concentration of alcohol for sterilization purpose
      o Normal catgut will completely resorb by 70 days
      o Eg: chromium catgut (12-15 days)
         ◾ Catgut coated with chromium layer
         ◾ Advantages — increase tensile + increase life span
         ◾ Main use in oro antral fistula suture

Eg: Vicryl
       ◾ Made of polyglycolic acid

Non – resorbable
       ◾ Eg: nylon
       ◾ Silk (BBS)
       ◾ Prolene
