This report describes the first use of a novel workflow for in-house computer-aided design (CAD) for application in a resource-limited surgical outreach setting. Preoperative computed tomography imaging obtained locally in Haiti was used to produce rapid-prototyped 3-dimensional (3D) mandibular models for 2 patients with large ameloblastomas. Models were used for patient consent, surgical education, and surgical planning. Computer-aided design and 3D models have the potential to significantly aid the process of complex surgery in the outreach setting by aiding in surgical consent and education, in addition to expected surgical applications of improved anatomic reconstruction.

3D Printing refers to a class of technology that can automatically construct 3-dimensional physical models from Computer Aided Design (CAD) data. Reduction of product development cycle time is a major concern in industries for achieving competitive advantage. Endodontic dentistry is the dental specialty concerned with the study and treatment of the dental pulp, and generally diagnose tooth pain and perform root canal treatment and other procedures relating to the interior of the tooth. This article, therefore, aims on being an assistive methodology in endodontics by applying 3D printing in order to reduce the strain involved in the tooth restoration process.

Objectives: Immediate post-operative reconstruction of calvarial bone by cranioplasty prosthesis in calvarial bone fibrous dysplasia. An easy and economical method for reconstruction of the defect. Methods: Surgical excision of right parietal cranial space occupied lesion was performed followed by fabrication of immediate postoperative period cranioplasty prosthesis by using clear heat polymerized polymethylmethacrylate. Results: The cranial defect created during excision of calvarial bone fibrous dysplasia was immediately replaced by cranioplasty prosthesis which was fabricated in the immediate post-operative period using heat polymethylmethacrylate. Conclusions: Polymethylmethacrylate is a very reliable thermoplastic material that can be prefabricated or even placed immediately after post-operative period to produce a suitable prosthesis. Polymethylmethacrylate implants have been outmoded by computer-aided design and computer-aided manufacturing and newer 3-dimensional printed implants, but these newer methods are accompanied by higher expenses and timing issues.

This clinical report describes a digital process of using a 3-dimensional (3D) virtual patient at an exaggerated smile view for the pre-treatment simulation of the prosthetic outcome. In addition, the virtual patient can be used to assist with the formulation of a prosthetically - driven surgical plan for static computer-aided implant surgery (s-CAIS) and the design of the computer-aided design and computer-aided manufacturing (CAD-CAM) prostheses.

This paper explains and demonstrates how to reduce time for preparation of 3-dimensional (3D) geometrical Computer-Aided-Engineering (CAE) model from 3D Computer-Aided-Design (CAD) data. In generally, CAE model preparation is labor intensive and takes long time. Main part of preparation work is simplification of 3D-CAD data to decrease mesh scale and without impacting the solution accuracy. The purpose of this study is to create automatic CAE model preparation technology for reduction of preparation time. In this study, automatic model preparation method is developed by using of geometrical and topological information of 3D-CAD data. Benchmark test is performed to proof the efficiency of the method.

A unique machining knowledge has led to several different perspectives between planners and operators as regards in designing a machining process plan. All precedents have shown the need to maintain a suitable machining process plan. Commercial Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) systems have facilitated the manipulation of 3D models to generate a machining process plan. The open Advanced Programming Interfaces (APIs) are also helpful in tailoring decision support systems to determine process plans. This study proposes an emergent system to generate flexible machining process plans. The proposed system considers the integration between design and manufacturing perspective to produce relevant machining process plan. The generation of process plans begins by considering the total removal volume of the raw material, estimating the removal features, thus analyzing and ordering several candidates of machining process plans. The total machining time and number of setups from each machining process plan candidate is analyzed and evaluated. Eventually, the proposed system is tested using several prismatic 3D models of a workpiece to show the outcomes.
