This paper introduces the Continuous Crossing Mattress Periosteal Suture Technique (CMPST), designed to enhance flap adaptation, and maintain the established apical displacement of the flap during various periodontal resective surgeries, particularly restorative-driven (or functional) crown lengthening in multiple teeth at anterior or posteriors areas. This suture technique securely positions the flap apically, just coronal to the bone, anchored at the periosteum, combining the advantages of both continuous and cross-compression sutures without compromising the esthetic results. By eliminating flap mobility, it ensures stable and intimate contact with underlying tissues. Further controlled studies are needed to assess the clinical applicability of this technique compared to other suture techniques.
