A wound is a disruption in tissue continuity which then undergoes the process of healing. Healing is a normal, coordinated and complex physiological process that includes a whole series of chemical and physiological reactions aimed at restoring the normal function and structure of the tissue after an injury. This process consists of four overlapping distinct phases that take place sequentially: hemostasis, the inflammatory phase, the proliferation phase, and the remodeling phase. Wound healing can occur through three mechanisms: primary, secondary and tertiary healing. In the case of wounds on the oral mucosa, primary healing is the preferred method without complications. Several factors, both local and systemic, influence the healing of oral mucosal wounds. These factors include wound size and depth, infection, gender, age, smoking, alcohol consumption, corticosteroid therapy, diabetes. Suturing the wound achieves the rejoining of separated tissue layers which is a prerequisite for primary healing, protecting against wound infection, reducting postoperative pain, and creating a smaller, more aesthetically pleasing scar. The oral surgeon's selection of appropriate instruments, materials, and suturing techniques is crucial. Suture materials can be natural or synthetic, resorbable or non-resorbable, and monofilament or polyfilament. Sutures can be continuous, spanning the entire wound length, or interrupted, with each individual suture tied separately. The most commonly used sutures in oral surgery include single sutures, cross sutures, vertical mattress sutures, horizontal mattress sutures, Gottlow sutures, continuous sutures with and without locking, relief sutures, combined sutures, suspended encompassing vertical sutures, suspended encompassing horizontal sutures and suspended periosteal sutures.
