Comparative Analysis Of 3d Printed Denture Resins With Traditional Denture Materials At The Micro Level, Aneeza Hussain, Caleb Beckwith, Gaffar Gailani

Publications and Research

The aim of this experiment was to evaluate and identify compression strength between traditionally manufactured acrylic dentures and additive manufacturing resin dentures. Specifically, the dentures produced by Uhler Dental, its Reveal line were compared against samples produced on the Formlabs Form 2 SLA, Stereolithography, 3D printer using their Denture Teeth A2 resin to test compression strength to assure they are compatible with the occlusal forces in the oral cavity. Using the ZwickRoell tensile testing machine, it appeared that the acrylic dentures were half as strong as the resin dentures. Then we went ahead to and did a comparative analysis under …

Retention Of Rapid Prototyped Complete Dentures Using Two Different Types Liquid Resin, Lina Khalaf Ismail, Mohammed Farouk Abdullah, Mohammed Mahmoud Dohiem

Future Dental Journal

Objectives: Comparing the retention of upper complete denture manufactured using two different denture base materials, both of them were manufactured using rapid prototyping method.

Methods: Nineteen patients were selected. For both groups, the dentures were manufactured using Rapid prototyping method following the next steps, a preliminary impression was made & trial denture bases were constructed on the primary casts for the upper & lower arches for a jaw relation record. A facebow record was used to mount the upper cast, while the lower cast was mounted using a centric relation record. Setting of artificial teeth was performed, then the denture …

The Influence Of Cbct-Derived 3d-Printed Models On Endodontic Microsurgical Treatment Planning And Confidence Of The Operator, Shreyas Oza, Johnah C. Galicia

Orthodontics and Endodontics Theses

Aims Use of 3D printed models in Endodontics has been gaining popularity since the technology to create them became more affordable. Currently, there are no studies that evaluate the influence of 3D models on endodontic surgical treatment planning and on operator confidence. Therefore, aims of this study were to: (i) Determine whether the availability of a 3D printed analogue can influence treatment-planning and operator confidence; and, (ii) Assess which factors of operator confidence are influenced, if any.

Materials and Methods Endodontists were asked to analyze a pre-selected CBCT scan of an endodontic surgical case and to answer a questionnaire that …

3d Printing Of High Viscosity Fluids And Its Application In 3d Printing Of Prosthetic Teeth., Abhilash Aditya

Open Access Theses & Dissertations

The advancement in technology has brought forward non-conventional manufacturing methods that are efficient and advantageous for specific applications. 3D printing is one such outcome, whose applications stretch from biomedical applications to daily products. 3D printing is a rapidly growing technology, and innovative research developments have proven versatility in creating physical objects. Simplification and constant improvement in Fused Deposition Modeling (FDM) operation result from decades of research. However, 3D printing is material-specific and contributes to shortcomings in the technology. The build-material dictates the extrusion parameters, including the material discharge rate and head speed for a continuous flow. Customization being the prime …

Fabrication Of Chemically-Functionalized 3dprinted Porous Scaffolds For Biomedical Applications, Eiman Hamed Matar Atalla Alblooshi

Theses

Hard tissues, such as bone and teeth, are natural composites of collagen nanofibers that are reinforced by inorganic calcium phosphate Nano crystallites, in the form of nanocomposites. The interlocking between these components in hard tissues explains their unique characteristics. Bone is mainly classified into two major types; compact and cancellous depending on the extent of porosity. Fractures in the compact bone can be treated using bone fixation implants, such as rods, screws, and plates, or can be totally replaced by bone implants if complete substitution is required. Cancellous bone, on the other hand, is highly porous and its substitution with …

Impact Of Grain Orientation And Phase On Volta Potential Differences In An Additively Manufactured Titanium Alloy, Jake T. Benzing, Olivia O. Maryon, Nik Hrabe, Paul H. Davis, Michael F. Hurley, Frank W. Delrio

Materials Science and Engineering Faculty Publications and Presentations

This work introduces a method for co-localized multi-modal imaging of sub-μm features in an additively manufactured (AM) titanium alloy. Ti-6Al-4V parts manufactured by electron beam melting powder bed fusion were subjected to hot isostatic pressing to seal internal porosity and machined to remove contour–hatch interfaces. Electron microscopy and atomic force microscopy-based techniques (electron backscatter diffraction and scanning Kelvin probe force microscopy) were used to measure and categorize the effects of crystallographic texture, misorientation, and phase content on the relative differences in the Volta potential of α-Ti and β-Ti phases. Given the tunability of additive manufacturing processes, …

Advances In Metal Additive Manufacturing: A Review Of Common Processes, Industrial Applications, And Current Challenges, Ana Vafadar, Ferdinando Guzzomi, Alexander Rassau, Kevin Hayward

Research outputs 2014 to 2021

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. In recent years, Additive Manufacturing (AM), also called 3D printing, has been expanding into several industrial sectors due to the technology providing opportunities in terms of improved functionality, productivity, and competitiveness. While metal AM technologies have almost unlimited potential, and the range of applications has increased in recent years, industries have faced challenges in the adoption of these technologies and coping with a turbulent market. Despite the extensive work that has been completed on the properties of metal AM materials, there is still a need of a robust understanding of processes, …

Rapid Prototyping Of Surgical Staples, Osama Al Takhayneh

University of Wollongong Thesis Collection 2017+

There is a current need for the development of new bone implant materials to overcome a variety of surgical, biological, and manufacturing drawbacks. There are several techniques used in the manufacturing of bone implants such as 3D printing. Rapid prototyping/3D printing is an important process in the development of implants used in bone fixation surgeries, its importance lies within the ability to customize and create patient specific systems to increase the efficiency of bone fixation surgeries. The main aim of this study is to develop and test new materials for the purpose of internal fixation implants, such as bone staples, …
