BACKGROUND: CAD/CAM reconstruction plates have become a viable option for mandible reconstruction. The aim of this study was to determine whether CAD/CAM plates provide higher fatigue strength compared with conventional fixation systems. MATERIAL AND METHODS: 1.0 mm miniplates, 2.0 mm conventional locking plates (DePuy Synthes, Umkirch, Germany), and 2.0 mm CAD/CAM plates (Materialise, Leuven, Belgium/DePuy Synthes) were used to reconstruct a polyurethane mandible model (Synbone, Malans, CH) with cortical and cancellous bone equivalents...

BACKGROUND: Free fibula flap is an option for primary restoration after disarticulation mandibular resection, though literature on technique refinements is scarce. The authors hypothesized that inset of the masseter, the key mandibular elevator muscle, at the reconstructed mandible may optimize functional recovery. METHODS: All patients undergoing reconstruction of mandibulectomy-condylectomy defect (January 2009 to January 2014) by means of a fibular flap were prospectively studied...

Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry...

Several methods are available to treat mandibular tumours. This case series demonstrates the feasibility of resection and immediate reconstruction with free rib graft in limited resource settings. Innovative technical modifications are described to handle the problem of reconstruction of the angle of the mandible and to provide increased bone bulk in the centre of the mandible. Early postoperative complications are few. Follow-up demonstrates good functional results.

A fracture of the mandible is a common trauma presentation amongst young males and represents one of the most frequently encountered fractured bones within the viscerocranium. Historically, assault was the dominant contributing factor but now due to the increased number of vehicles used per capita, motor vehicle accidents are the primary cause. Mandibular fractures can be classified anatomically, by dentition, by muscle group and by severity. The fracture may also be closed, open, comminuted, displaced or pathological...

STATEMENT OF PROBLEM: Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear...

Surgical management of extensive tumors in the mandibular region leads to massive disfigurement of the face. Also the prosthetic outcome of such patients rehabilitated with free soft tissue flaps is very poor. Reconstruction of extensive defects to overcome the disfigurement is a challenging procedure and can be achieved with free fibula flap. Free fibula graft provides sufficient length of bone for the reconstruction of the postsurgical defects. Excellent vascularity of fibula flap allows for easy uptake of the graft and osseointegration of the dental implants...

Mandibular osteotomies are usually required to treat craniomaxillofacial disorders. Losses of mandibular continuity result in esthetic and functional deficiency. During the past 30 years, the spread of the computer-assisted surgery techniques, rapid prototyping, and surgical navigation technique has improved the reliability and the outcomes of mandibular resections and reconstructions, by providing realtime feedback to surgeon. Recent studies reported the feasibility and the precision of surgical navigation applied to mandibular surgical resection and reconstruction with fibula flap but none of them describes a method to navigate the jaw allowing its full motility during the operation...

BACKGROUND: Tunneled transposition of the facial artery myomucosal (FAMM) island flap on the lingual side of the mandible has been reported for intraoral as well as oropharyngeal reconstruction. This modified technique overcomes the limitations of short range and dentition and further confirms the flexibility of the flap. This paper presents a case of reconstructing secondary soft palatal defect due to flap necrosis following two-flap palatoplasty in irradiated patient with lingually transposed facial artery myomucosal island flap...

After mandibulectomy in cancer surgery, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap in patients in poor condition. However, the rate of complications for mandibular reconstruction is higher with a reconstruction plate than with vascularized bone grafts. We have developed a costal cartilage wrapping method to prevent exposure of the mandible reconstruction plate. The eighth costal cartilage was removed and split into 2 pieces to wrap around the reconstruction plate...

Osteoradionecrosis is defined as bone death secondary to radiotherapy. There is a relationship between the radiation dose received and the occurrence of osteoradionecrosis of the jaws, with the risk increasing above a dose of 60Gy. In cases of class III mandibular osteoradionecrosis, a segmental resection can be indicated. Current practice is to completely remove the affected bone up to the point where the bone looks healthy and is bleeding. Exact resection planning and the use of guided surgery based on imaging of the bone changes have not been reported so far...

Craniofacial morphology varies among individuals, which is regulated by the interaction between genes and the environment. Soft-diet feeding is a widely-used experimental model for studying the association between the skeletal morphology and muscle-related loading on the bone. Traditionally, these studies have been based on linear and angular measurements provided on two-dimensional (2D) radiographs in the lateral view. However, 2D observation is based on simplification of the anatomical structures and cannot detect three-dimensional (3D) changes in detail...

The majority of patients often have functional problems after undergoing jaw reconstruction. These patients require intense rehabilitation, including surgical and prosthodontic procedures to maximize function, esthetics, and to preserve mastication, speech, and appearance. This clinical report describes the rehabilitation of a patient who had a large tumor resection of ameloblastoma of the mandible resulting in hard and soft tissue deficiency. The mandible was reconstructed with an iliac bone graft with simultaneous tumor removal...

PURPOSE: This study develops a novel hybrid (NH) reconstruction plate that can provide load-bearing strength, secure the bone transplant at the prosthesis favored position, and also maintain the facial contour in a mandibular segmental defect. A new patient-match bending technique which uses a three-dimensional printing (3DP) stamping process is developed to increase the interfacial fit between the reconstruction plate and mandibular bone. MATERIALS AND METHODS: The NH reconstruction plate was designed to produce a continuous profile with non-uniform thickness and triangular cross-screw patterns with a locking-screw feature at the plate base...

This study investigated the correlation between the 3-dimensional changes in midfacial soft tissues, including the parasagittal area and maxilla-mandible complex, after Le Fort I maxillary posterior impaction and bilateral intraoral vertical ramus osteotomy (B-IVRO), using cone-beam computed tomography (CBCT). This retrospective study included 22 skeletal Class III patients (6 men and 16 women; mean age 21.6 years) who underwent orthognathic surgery. Three-dimensional CBCT images taken before and 1 year after surgery were superimposed based on the cranial base...

This study aimed to analyze the changes in mandibular morphology after bilateral mandibular distraction osteogenesis (BMDO) in children with Pierre Robin sequence. The positions of the condyles were analyzed in reconstructed three-dimensional craniomaxillofacial images obtained for 18 children before and 8-12 weeks after BMDO. Differences between pre- and postoperative parameters were assessed using paired t-tests. After surgery, a significant decrease in superior joint space was detected (P<0.05), but no change in anterior joint space or posterior joint space was observed...

Distraction osteogenesis for the augmentation of severe alveolar bone deficiency has gained popularity during the past two decades. In cases where the vertical bone height is not sufficient to create a stable transport segment, performing alveolar distraction osteogenesis (ADO) is not possible. In these severe cases, a two-stage treatment protocol is suggested: onlay bone grafting followed by ADO. An iliac crest onlay bone graft followed by ADO was performed in 13 patients: seven in the mandible and six in the maxilla...

BACKGROUND: The vascular fibula flap is an ideal choice for function and appearance reconstruction of mandible. Despite the high success rate, "late complications" such as Ti plate exposure and local infection related to osteosynthesis are not uncommon. PATIENTS AND METHOD: A retrospective cohort of patients who received vascular fibula reconstruction for mandible from January 2011 to December 2013 from the Department of Oral and Maxillofacial Oncology in a tertiary hospital were charted: clinical, pathological, and therapeutic factors were analyzed for late complications in univariate and multivariate analyses...
