The attainment of primary wound closure is one of the major determining factors of success in oral surgery. Especially when dealing with regenerative or augmentative procedures, healing in a submerged environment is crucial to achieving the desired treatment result. In this context, the use of a microsurgical approach and layered suturing techniques is of utmost importance for precise and meticulous wound closure. However, microsurgical wound closure using both mattress sutures and interrupted sutures is very time consuming and may be detrimental to wound healing because of trauma and extended surgical time. The double-sling suture, a modified suture technique that combines two interrupted sutures that have different bite sizes and engage different tissue layers, is able to predictably and efficiently close the surgical site for improved wound healing. This article describes this new technique and presents two case examples.
