Reconstructionof Human Mandibular Continuity Defects with Allogenic Scaffold and Autologousmarrow Mesenchymal Stem Cells
Background Mandibular continuity defects occur after tumor resection, maxillofacial injury, or osteomyelitis. Despite the current availability of a plethora of treatment modalities, bone substitutes, and various clinical adjuncts, an exact reconstructive recapitulation of large bony defects continues to be beyond reach. In this clinical pilot study, we report a novel method for reconstruction ...
متن کاملRegenerating Mandibular Bone Using rhBMP-2: Part 1-Immediate Reconstruction of Segmental Mandibulectomies.
OBJECTIVE To describe a surgical technique using a regenerative approach and internal fixation for immediate reconstruction of critical size bone defects after segmental mandibulectomy in dogs. STUDY DESIGN Prospective case series. ANIMALS Dogs (n = 4) that had reconstruction after segmental mandibulectomy for treatment of malignant or benign tumors. METHODS Using a combination of extraor...

OBJECTIVE To describe a surgical technique using a regenerative approach and internal fixation for reconstruction of critical size bone defect non-union mandibular fractures. STUDY DESIGN Case series. ANIMALS Dogs (n = 6) that had internal fixation of defect non-union mandibular fracture. METHODS In 5 dogs, the repair was staged and extraction of teeth performed during the initial procedu...
متن کاملBridging Plate Development for Treatment of Segmental Bone Defects of the Canine Mandible: Mechanical Tests and Finite Element Method.
With regard to the canine mandible, a mistaken concept of application is to assume that systemic plate-bone resistance is provided by the implant so that biomechanical position could be ignored. Because the alveolar border of the mandible is a tensile zone, the plate would ideally be positioned near this area while avoiding important structures. The aim of this study was to develop 2 bridging p...
متن کاملRehabilitation of an Auricular Defect Using Surgical Stent
Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient’s expectation. Loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sound...
