Primary wound coverage, and tension-free wound closure are considered important principles for successful GBR procedures (1). Essentially, we want to make sure the graft material and the membrane are not exposed to the oral cavity. Proper suturing techniques, including avoiding excessive tension on sutures, are essential to achieving, and maintaining, primary closure (2).
This video reviews two cases to provide some tips on how best to suture sites for larger grafting cases with significant defects that might prove challenging for primary closure. Sutures employed in the cases are Chromic Gut or Vicryl (PGA). One quick tip from the second case is that it is important to make sure you enter the buccal flap below the mucogingival junction so you can take advantage of the elasticity.
