ObjectiveTo introduce a novel method of split-thickness labial flap in maxillary anterior ridge horizontal augmentation and to evaluate its efficacy and morbidity.Materials and Methods230 patients were selected to receive either particulate or onlay grafting. A split-thickness labial flap was applied to cover the grafted area and close the wound. The incidence of postsurgical complications and the level of patient discomfort were evaluated. A visual analog scale was used to quantify the amount of pain and swelling in the patients.ResultsIn all 375 surgical sites, passive primary closure was achieved with the split-thickness labial flap method. Membrane exposure after surgery was seen in 6 cases in the onlay group and in 4 in the particulate group. No long-lasting pain (>1week), paresthesia, or signs of infection occurred during the follow-up period of 6 months. The mean pain and swelling scores in the particulate graft group (2.75 ± 3.01 and 2.02 ± 2.51, respectively) were lower than the scores in the onlay graft group (3.18 ± 2.79 and 3.85 ± 2.25, respectively).ConclusionsThe flap advancement technique presented in this study facilitates clinically passive primary closure. This technique can be used successfully in both particulate and onlay horizontal graft procedures.
