 4.Purpose
This study retrospectively analysis the survival rate of dental implants and risk factors in patients undergoing oral functional reconstruction with vascularized fibula bone flap.
 
 5.The method and the result
From 1992 to 2017. total 109 patients, Oral cancer 42 cases 137 pcs dental implants ,non-cancer (benign but advanced bone destructed ,osteomyelitis, facial trauma. etc) 67 cases 261 pcs dental implants placement in vascular fibula bone flap reconstructed patients. A stereolithographic (STL) 3D model of the jaw was produced, the econstruction plate was then pre-bent before-operative .

After tumor resection, and obtaining negative margins confirmed by frozen section, the reconstruction plate was fixed to the mandible. A bundle of wooden tongue depressors ( 5 pieces) were stacked on each other and used as a template to determine the umber of bone struts, and guide the fibula bone osteotomies.

After harvesting the fibula osteoseptocutaneous flap and completing the boneosteotomies as planned by the wooden template, dental implants positions were
determined according to the opposing dentures. The implantation into the fibula
construct was done on a side table. After that, a vector guider(10mm length) was
mounted on the construct, and the whole unit (fibula-dental implants-vector guides)
was transferred to the recipient mandible and fixed in the best inter-arch relationship
possible with the upper jaw.

In non-cancer patients taken palatal keratinized mucosa
graft around the dental implants. The fibula vertical distraction osteogenesis method
or double barrel technique method solved the fibula bone height discrepancy with
neighboring native mandible problem.
 
6. Discussion
 
7. Conclusion

Vascularized fibula bone flap combine with dental implants not only esthetic profile was maintain but also oral chewing function was acquired. The cost-effective problem must be consideration to patient.
