In three grafting sites, wound dehiscence was observed in the early postoperative period. In this case, mouthwash was used, and the sharp edges of the exposed graft were corrected with a round bur under saline irrigation. Patients were followed up until implant placement surgery with regression of dehiscence. In one patient, the bone block separated from the residual bone during the implant placement session. In this case, implant placement surgery was performed simultaneously with directed tissue regeneration. In five surgical sites, the mandibular nerve was exposed during block grafting. All these patients reported mild numbness of the lips at follow-up one week later. This transient numbness lasted eight weeks, and none of the patients had numbness during the implant placement session. A total of 46 implants were placed in 16 patients (4 Megagen Anyone, Megagen, Seoul, South Korea, 2 Strauman Bone Level, Straumann AG, Basel, Switzerland and 40 Megagen ST, Megagen, Seoul, South Korea). No significant differences were found between the two groups regarding the number of complications (p > 0.05). The multilevel mixed-effects model analysis confirmed the robustness of these findings, taking into account the within-patient correlations.
