What is mucoperiosteal flap

Silk is easy to handle, ties with a slip knot, and is relatively inexpensive compared with other nonabsorbable suture materials currently available. However, there are distinct disadvantages associated with silk. First, it is nonabsorbable so must be removed, usually a week or so later. Second, silk specifically is a multifilament that "wicks" or pulls bacteria and fluids into the wound site. Therefore silk is not the suture material of choice when any sterile materials are placed under a mucoperiosteal flap.
