Periosteal Sutures for Connective Tissue Stabilization

The test group underwent the same surgical approach, except that a periosteal simple interrupted suture was put in place prior to the continuous interlocking sutures. This vertical simple, interrupted suture was used in locations with strong connective tissue or frenal attachments. It was placed by commencing the needle 2 mm coronal to the base of the connection and moving it apically by crossing the connective tissue attachment up to 6 mm before tying the knot. The thick connective tissue attachments were supposed to be moved and stabilized by this suture in a more coronal position. Vicryl 4-0 resorbable sutures were used for all periosteal sutures (VICRYL RAPIDE™ (polyglactin 910) Suture, Ethicon US, LLC, Irvine, CA, USA). Per surgery site, 3 to 4 periosteal sutures were typically inserted (Figure 2). Finally, the same skilled periodontist conducted all of the procedures.
