Dordick, B, Coslet, J, Seibert, J. Clinical evaluation of free gingival graft placed on alveolar bone. Part I. Clinical predictability. J. Perio. 47:660, 1976

60 cases requiring free autogenous gingival grafts were selected. The indications for grafting included inadequate zones of attached gingiva and/or gingival crevices that could be probed to the MGJ. Patients were randomly assigned to 2 groups. Group A had grafts placed on denuded alveolar bone. Group B had grafts placed on periosteum an/or connective tissue. Incisions were beveled. periosteum were performed by sharp dissection. The palate was used as the donor site. Grafts were sutured into place. Coe pak used. Measurements at 7, 14, 21, 42,60, and 120 days.

• All 60 grafts were successful.
• No statistically significant difference between the pain levels in Group A and B, although on the average.
• No sequestration or infections.
• Healing lagged in the grafts placed on denuded bone. At about the 2nd or 3rd post-op week visit, the delayed healing caught up.
• On examination of grafts for mobility showed that in the cases placed on periosteum more than 17 of 30 exhibited post-op graft mobility in either an anterior-posterior or apico-coronal direction or both, while none of the denuded bone demonstrated this clinical finding. Mobility was not usually observed in grafted tissue until 2, 4 or 6 months post-op.
• Improved hemostasis in the recipient site in the direct osseous technique has significant clinical application.

The tables showed a of fenestrations and dehiscences (soft tissue) which were not mentioned
