Abstract: Objective:?To analyze the clinical effect of implant-supported prosthetic rehabilitation after reconstruction with fibular muscle flap for mandibular defect. Methods:?Fifteen patients who underwent mandibular defect reconstruction with fibular muscle flap due to tumor or inflammation were included. Evaluate the retention rate of implants, marginal bone level of implants, depth of soft tissue exploration, and modified sulcus bleeding index 2 years after implant restoration. Results: A total of 62 implants were included, and the implant retention rate was 100% after 2 years of functional use. There was no statistically significant difference in the marginal bone level of the implant, and there was no statistically significant difference in the depth of soft tissue exploration around the implant and the modified sulcus bleeding index (P＞0.05). When the depth of implant probing is greater than 4 mm, the modified sulcus bleeding index significantly increases (P＜0.05). Conclusions:?The reconstruction of mandibular defect with fibular muscle flap and implantation of dentures has achieved good clinical efficacy. Implants with a soft tissue depth of less than 4 mm around the implant exhibit better stability.
