As a relatively new material deployed in additive manufacturing (AM), silicone and its composites have the potential to realize tunable functionality heterogeneous, architected properties for number of applications requiring low modulus, elastic materials. Continuous fiber reinforced been developed AM achieve various complex structures that are lightweight with high mechanical properties. silic...

The efficacy of computer-aided technologies in the design and manufacture of maxillofacial prostheses has not been fully proven. This paper presents research into the evaluation of direct and indirect additive manufacture of a maxillofacial prosthesis against conventional laboratory-based techniques. An implant/magnet-retained nasal prosthesis case from a UK maxillofacial unit was selected as a...

BACKGROUND/AIMS High viscosity silicone oils are used as tamponade agents to increase the resistance to emulsification; however, this makes the oils more difficult to inject. Increasing the extensional viscosity is one way to reduce emulsification. This study aimed to evaluate how silicone oils with increased extensional viscosity behave in terms of their ease of injection. METHODS The shear ...

Objectives: Cuspids migrated medially into the position of lateral incisors create unpleasant esthetic appearances. This kind of a situation and the related disturbances such as the diastemas and the positional and/or proportional irregularities, create major challenges in front of the dental practitioners. Materials and Methods: The diagnostic additive wax-up, gingival esthetic recontouring, v...

Medical devices, such as silicone-based prostheses designed for soft tissue implantation, often induce a suboptimal foreign-body response which results in hardened avascular fibrotic capsule around the device, leading to patient discomfort or implant failure. Here, it is proposed that additive manufacturing techniques can be used deposit durable coatings with multiscale porosity on surfaces pro...

BACKGROUND Peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. Use of silicone may improve outcomes of these repairs. In this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. METHODS This experimental stud...

PURPOSE The purpose of this study was to verify the clinical-feasibility of additive manufacturing by comparing the accuracy of four different manufacturing methods for metal coping: the conventional lost wax technique (CLWT); subtractive methods with wax blank milling (WBM); and two additive methods, multi jet modeling (MJM), and micro-stereolithography (Micro-SLA). MATERIALS AND METHODS Thi...
