Long-Term Outcomes of Dental Implants Placed in Fibula-free Flaps Used for Reconstruction of Maxillo-Mandibular Defects.

The use of dental implants and prostheses in the oral rehabilitation process after maxillofacial ablation procedures is now regarded as standard practice. Numerous donor sites for free vascularized bone transfer in head and neck reconstruction have been well-documented in the literature including the ribs, ilium, fibula, scapula, and radius. Among these, the fibula is the most commonly used and studied for placing endosseous implants and for rehabilitation purposes. There are benefits and drawbacks to the fibula flap. This paper aims to provide a review of the current research on the long-term

Customed 3D-printed Polyetheretherketone (PEEK) Implant for Secondary Salvage Reconstruction of Mandibular Defects: Case Report and Literature Review.

Given the insufficient height of single-barrel fibula and inadequate bone volume of double-barrel vascularized fibula in mandibular reconstruction, it is a better choice to combine the upper full-thickness vascularized fibula with the lower half-thickness nonvascularized fibula. However, the nonvascularized fibula may fail due to complications, affecting the facial shape and occlusal function. Polyetheretherketone is a thermoplastic polymer used for bone defect reconstruction due to its good mechanical properties and biocompatibility. This case report mainly presents a secondary salvage recons…

Methods: Three patients underwent mandibular reconstructio…

Management of Progressive Mandibular Fibrous Dysplasia With Radical Resection and Immediate Reconstruction Using Autoclaved Autograft: A Case Report.

Fibrous dysplasia is an uncommon condition in which fibrous elements and immature bones progressively replace normal skeletal tissue. When the mandible is involved, patients may develop swelling, asymmetry, and functional difficulties, which require careful differentiation from other jaw pathologies to avoid misdiagnosis. This report describes the case of a 48-year-old man who presented with a slowly enlarging, painless swelling of the lower jaw accompanied by mobile teeth and impaired chewing ability. Clinical and radiographic investigations revealed a diffuse lesion with a characteristic gro

Mandibular reconstruction using an iliac bone flap with perforator-supported external oblique abdominal muscle island: a pilot study.

The deep circumflex iliac artery (DCIA) flap is one of the bone flaps commonly used for mandibular reconstruction. Observation of the skin paddle and Doppler ultrasound are methods that are usually used to monitor DCIA flaps after mandibular reconstruction surgery. The aim of this study was to introduce a novel DCIA flap with a perforator-supported external oblique abdominal muscle (EOAM) island for postoperative flap monitoring. This study included five patients who underwent mandibular reconstruction using this modified technique. The DCIA flap and the EOAM island supplied by the ascending b…

Patient-Specific Bioimplants and Reconstruction Plates for Mandibular Defects: Production Workflow and In Vivo Large Animal Model Study.

A major challenge with extensive craniomaxillofacial bone reconstruction is the limited donor-site availability to reconstruct defects predictably and accurately according to the anatomical shape of the patient. Here, patient-specific composite bioimplants, consisting of cross-linked poly(trimethylene carbonate) (PTMC) networks and β-tricalcium phosphate (β-TCP), are tested in vivo in twelve Göttingen minipigs in a large mandibular continuity defect model. The 25 mm defects are supported by patient-specific titanium reconstruction plates and receive either osteoconductive composite bioimplants

Reconstruction of Complex Oro-Mandibular Defect Using Free Fibula Flap and Lateral Sural Artery Flap: A Case Series.

Although it has been shown that polymorphisms in one-carbon metabolism (OCM) pathway are associated with gastric cancer (GC), their interactions and contributions for patients' survival are elusive. In this study, we investigated the effects of polymorphisms and their interactions on the survival of GC patients, including genes of Methylenetetrahydrofolate reductase (MTHFR 677C > T, 1298A > C), Methionine synthase reductase (MTRR 66A > G), Methionine synthase (MTR 2756A > G), and Thymidylate synthase (TS 3'-UTR ins6 > del6, 5'-UTR 2R > 3R). We recruited 919 GC patients from 1998 to 2006. The K

Chimeric LSMAP Double-barrel Fibula Free Flap: Goal-oriented Surgical Technique and Tips for One-stage Mandibular Reconstruction.

Composite oromandibular defects involving jaw bones, intraoral and skin/soft tissues, or dynamic structures such as the tongue, soft palate, and pharynx are real reconstructive challenges even today. Despite improvements in oral dental rehabilitation, another complex task to deal with in young patients with dentate or nonatrophic mandible is correcting a too large vertical occlusal dimension, which makes the prosthodontic rehabilitation very challenging. Instead of using more complex and time-consuming methods such as simultaneous free flaps and to avoid further bone graft and second-stage rev

Application of optimized digital surgical guides in mandibular resection and reconstruction with vascularized fibula flaps: Two case reports.

RATIONALE: Currently, digital surgical techniques have been widely used in the precise treatment of mandibular resection and reconstruction with fibula flaps. Utilizing these innovative techniques in surgical planning and hardware fabrication before surgery has shown to provide great help. However, it is difficult for even experienced surgeons to place the preformed reconstruction plate in the same position as its preoperative design, causing surgical results to differ from preoperative planning. This study aims to solve these acknowledged challenges by creating newly designed equipment. PATI
