Customized Titanium Mesh for Repairing Cranial Defects

Abstract

Titanium cranioplasty is one of the well-established and widely used techniques for repairing cranial defects. In this paper, we present an improved way to design and create titanium meshes with more evaluation process. Computed tomography scan data of patients were used to create three-dimensional virtual models. Implants were designed with NX ImageWare 13.2 (Siemens PLM Software, Plano, TX). Final titanium meshes were assessed by Geomagic Studio 12 (Geomagic, Inc., Morrisville, NC) and NX ImageWare 13.2.Titanium meshes were designed and applied to cranioplasty surgery on 8 patients. Postoperative results were evaluated by computed tomography scanning and further analyzed with rainbow difference tomography. All patients were satisfied with the outcome. With this method, surgeons, engineers, and patients work together to evaluate and edit implant design. Our method provides better communication and comprehensive evaluation, which result in a satisfying outcome.

The 3D printed titanium mesh with high porosity has better repair effects than that with low porosity

“…In oral implant surgery, titanium mesh plays an important role in the bone reconstruction in patients with large area or multiple tooth position jaw defects. Titanium mesh acts as a mechanical barrier membrane and it essentially acts as a "tent" to provide a su cient low pressure space for the formation of new bone in alveolar ridge incremental surgery, which is conducive to the regeneration and repair of large-area bone defects [13,14]. Recent studies have shown that titanium mesh effectively ensures that patients with bone defects obtain su cient bone increment.…”

Product Lifecycle Management Strategy for the Definition and Design Process of Face Implants Oriented to Specific Patients

“…Therefore,functional restorationis achieved through those devices [1]. From those is obtained a surer, shorter and timepredictable surgery [2].…”

“…Third, evaluatethe accuracy of the PSI compared with the biological surface. Fourth, piece evaluation [2]. The development of those steps in the process of PSI deviceinvolve tools such asreverse engineering (RE), computer-aideddesign -manufacturing-engineering (CAx), 3D modeling, and rapid prototyping (RP) techniques [6], [7].…”

“…Implant design process is complex.To achieve medicalrequirementit demands lots of time and effort. That is why a specialized staff is mandatory, as well a complete evaluation of skull condition, soft tissue bundle, greater accuracy, and time during trauma treatment [1], [2].The use of specialized software allows reducing the vagueness in precision and accuracy [5]. This implies thata multidisciplinary team must articulate different profiles in the organized structured way insidea collaborative workflow,defining roles and activities atPSI development.…”
