Patient-Specific Mandibular Reconstruction Plates Increase Accuracy and Long-Term Stability in Immediate Alloplastic Reconstruction of Segmental Mandibular Defects

Customized mandibular reconstruction plates improve mechanical performance in a mandibular reconstruction model

The purpose of this paper was to analyze the biomechanical performance of customized mandibular reconstruction plates with optimized strength. The best locations for increasing bar widths were determined with a sensitivity analysis. Standard and customized plates were mounted on mandible models and mechanically tested. Maximum stress in the plate could be reduced from 573 to 393 MPa (-31%) by i...

Toward patient specific long lasting metallic implants for mandibular segmental defects

Reconstruction of Lateral Mandibular Defects with Soft Tissue Loss: The Role of the Submental Flap

Introduction: Mandibular continuity defects after pathologic resections or traumatic events are difficult cases for reconstruction. Defects involving both hard and soft tissue loss are more challenging, because of problems in soft tissue coverage. The role of the submental flap in this regard is presented.   Materials and Methods: In a retrospective study from the archived files of Ghaem Hospi...

A Three Dimensional Analysis of Reconstruction Plates Used in Different Mandibular Defects

In this study, the reasons of breaking of the reconstruction plates used in mandibular continuity or mandibular defects were investigated. The study was conducted on 3 cases in which reconstruction plates were used for tumor resection or invasive wound. The objective was to evaluate the mechanical stress in reconstruction plates by means of the finite element method. Three dimensional model of ...

Reconstruction plates used in the surgery for mandibular discontinuity defect

OBJECTIVES The purpose of this study was to analyze the survival rate of reconstruction plates that were used to correct mandibular discontinuity defects. MATERIALS AND METHODS We analyzed clinical and radiological data of 36 patients. Only discontinuous mandibular defect cases were included in the study. Reconstruction plate survival rate was analyzed according to age, gender, location of de...
