Patient-specific Reconstruction Plate for Segmental Mandibular Defects

The mandible's horseshoe-shaped anatomy makes the reconstruction of segmental defects a challenging procedure. Conventional reconstruction typically relies on alloplastic plates to bridge bony stumps; however, these require extensive intraoperative bending, often resulting in imperfect adaptation, press-to-contact fixation, and residual stresses that increase the risk of hardware fatigue and fracture. Recent advances in computer-aided design and manufacturing (CAD/CAM) and virtual surgical planning (VSP) have improved precision in maxillofacial reconstruction. Patient-Specific Reconstruction Plates (PSRP), developed from virtual planning and patient-specific anatomical data, offer a bespoke contour adaptation, predictable screw positioning, and elimination of press-fit deformation. This customization improves alignment, mechanical stability, and long-term outcomes.

Stryker's Surgeon iD Mandible Reconstruction Plates: A Retrospective Post Market Follow Up

A retrospective post market follow up to confirm safety and performance of Stryker's Surgeon iD Plates (SMRP) medical device. The study is performed to confirm the product's performance and safety by systematically collecting clinical data on its use.

Registry to Collect Data on Patients Undergoing Segmental Mandibular Defect Reconstruction Following Oral Squamous Cell Carcinoma Resection and Drugs-induced Osteonecrosis

Prospective will be collected in a minimum of 300 patients presenting with an acquired segmental mandibular defect ≥ 2 cm secondary to OSSC removal and drugs-induced osteonecrosis, and who require mandibular reconstruction.

Evaluation of an Universal Surgical Device for Mandibular Reconstruction.

Fibula free flap is the gold standard for mandibular reconstruction. The shape of the fibula requires osteotomy that can be performed with a custom surgical guide. The use of surgical guide shorten surgical time, enhances the precision of the surgeon and reduces morbidity. Since 2008 custom surgical guide have been used in the hospital department and the clinical team have noticed a number of elements, which leads investigator to think that it would be possible to perform this kind of procedure using an universal guide. The aim of this study is to assess the possibility to perform mandibular fibula free flap reconstruction with an universal guide.

Standardized Osteotomy Guides for Free Flap Reconstruction of Continuous Defects of the Jaws - a Simplified Method

The aim of the present project is to evaluate the outcome from reconstruction of the jaws, with a standardized simplified technique, after a continuous defect. The primary objective is to measure recurrence of the tumour is present as a marking for insufficient resection margins. Secondary objectives are measures of survival of transplanted tissues, registered complications at follow-up and measures of healing between segments of transplanted bone (bone bridging).

Validation of the O-bridge Protocol: a Prospective, Multicenter Trial

Surgical reconstruction to restore oral function and aesthetics after major ablative surgery in the oral cavity forms a challenge to maxillofacial surgeons, and greatly impacts patient' quality of life (QOL). The "Oncological-bridge (O-bridge®)" protocol, which offers (immediate/delayed) fixed prosthetic rehabilitation in a minimum of sessions and a strongly reduced two-week treatment time.
