Abstract

Abstract: PURPOSE: To investigate the effect of increasing vertical bone height for patients of mandible defects reconstructed with vascular fibular flap. METHODS: A total of 12 patients with mandibular defects were selected who wanted to receive dental implantation repairment after vascularized fibular reconstruction. Vertical bone augmentation was performed using the residual fibula segment, and dental implants were implanted in the same stage or second stage, and finally the dentures retained with implants were completed. Postoperative bone level, implant stability and survival rate were statistically analyzed using SPSS 19.0 software package. RESULTS: The bone loss of segment A and B were (0.94±0.18) mm and (0.89±0.15) mm 6 months after surgery, and (1.16±0.21) mm and (1.07±0.17) mm 12 months after surgery, respectively. ISQ values were (67.25±6.43) and (71.08±4.89) 6 and 12 months after implant implantation, respectively. Marginal bone level was (0.65±0.12) mm and (0.76±0.18) mm 6 and 12 months after implantation, respectively. The implant survival rate was 87.1% 1 year after surgery. CONCLUSIONS: Non-vascularized fibula has reliable anti-absorptive capacity, which can provide sufficient bone mass for implant implantation and maintain its long-term stability and survival rate in cases of insufficient vertical bone height after mandibular reconstruction.
