Outcomes and influential factors in functional and dental rehabilitation following microvascular fibula flap reconstruction in the maxillomandibular region: a systematic review and meta-analysis. Maxillofac Plast Reconstr Surg 2023; 45:24.

Abstract
BACKGROUND This systematic review and meta-analysis aimed to evaluate the factors influencing and success rates of dental implants for functional and dental rehabilitation following microvascular fibula flap reconstruction in the maxillomandibular region. MAIN TEXT We conducted a comprehensive search of electronic databases, including MEDLINE, Web of Science, Embase, Scopus, and Cochrane's CENTRAL, as well as gray literature sources and manual searches of notable journals. The search was performed from inception until February 2023. Studies were included if they examined functional and dental rehabilitation outcomes in patients receiving maxillofacial reconstruction using microvascular fibula flaps and were retrospective or prospective cohort studies involving human subjects. Case-control studies, research involving other reconstruction methods, and animal-based studies were excluded. Data was extracted and confirmed by two independent researchers, and risk of bias was assessed using the Newcastle-Ottawa Scale. Meta-analyses were conducted for dental implant and graft success rate, with separate analyses for different factors affecting the outcome. Heterogeneity was evaluated using Cochran's Q test and the I2 test. The pooled success rate for implants was 92% and for grafts, 95%, with significant heterogeneity. Implants in fibular grafts had a 2.91 times higher failure rate than those in natural bones. Radiated bone and smoking were identified as factors influencing implant failure, with radiated bone having a 2.29 times higher risk and smokers having a 3.16 times higher risk compared to their respective counterparts. Patient-reported outcomes showed improvements in key areas such as dietary intake, mastication, speech, and esthetics. The success rates declined over time, emphasizing the importance of long-term follow-up. CONCLUSIONS Dental implants in free fibula grafts generally have favorable success rates, with minimal bone resorption, manageable probing depths, and limited bleeding on probing. Implant success is influenced by factors such as smoking and radiated bone.

Simultaneous Implant Placement in a Mandibular Defect Reconstructed With a Free Fibula Graft and Fabrication of a Fixed Metal Porcelain Prosthesis. J Craniofac Surg 2018; 29:1307-1311.

Abstract
This clinical report presents the multidisciplinary treatment approach for a 23-year-old male patient who underwent a total mandibular reconstruction due to trauma in the past and experienced postoperative complications. For his retreatment, exposed fixation plate was removed and infected bone was debrided and then a free fibula graft augmentation with simultaneous implant placement procedure was performed. After an osseointegration period of 6 months, a screw-retained porcelain fused to metal fixed prosthesis was fabricated and delivered.
