“…During and subsequent to surgical trauma the blood supply of gingival tissues is critical to their healing. This has been well established by histologic studies in dogs after vessel perfusion (Staffileno et al 1962. Oliver et al 1968, Kon et al 1969, Novaes et al 1976).…”

Capillary blood circulation following experimental wounding was observed by fluorescein angiography. Contralateral punch wounds 1.5 mm in diameter were made in healthy mandibular labial attached gingiva of 31 volunteers. Areas of ischemia were clearly visible angiographically 6 hours after wounding and were significantly greater in area (P less than 0.05) and wider (P less than 0.01) for wounds in the long axis of mandibular incisors (N = 14) than those on the vertical midline of the gingival papillae (N = 17). The ischemic changes occurred exclusively cranial to the experimental wounds. By the third day the epithelium adjacent to the wound margin in the central part of the ischemic area had necrotized, thus extending the wound coronally. By the seventh day the axial wounds were significantly (P less than 0.001) larger than the papillary wounds. The data strongly suggest that the blood supply of mandibular labial attached gingiva is preferentially oriented in an apico-coronal direction and that the capacity for collateral circulation is dependent upon local differences in vascular structure. The findings are applicable to flap design in periodontal surgery.

“…Attached gingiva was created first by denuding an extensive area of alveolar bone; however, this procedure resulted in protracted and painful postoperative periods and some loss of crestal bone 2,3 . Periosteal retention and periosteal fenestration procedures also have been used to create gingiva, but they were reported to be unpredictable 4‐6 . With the continued refinement of mucogingival surgery, emphasis has been placed on conserving and repositioning the existing gingiva; therefore, the apically positioned flap was introduced 7 .…”
