INTRODUCTION
Surgery involves the creation of a wound, and proper closure of this wound is usually necessary to promote optimal healing. Suturing a wound positions and secures the surgical flaps to promote healing.
Advantages of suturing:
Promotes healing Prevents complications Infection Hemorrhage Tissue necrosis Preserves the normal contour and shape
of the tissue.
Surgical instruments:
Suturing needle Suturing material Needle holder Tissue forceps Suture scissors
Patterns of the suture needle according to accessibility
Straight suture needles: > For skin closure Curved suture needles > For intraoral suturing >For deep suturing Half circle suture needles >For intraoral suturing
Types of suture material according to resorption
Non-Absorbable suture materials Absorbable suture material
