Recent Advances in Additive Manufacturing, Applications and Challenges for Dentistry: A Review

Abstract

Technological advancement in the field of dentistry has to be proven in new avenues for professionals as well as laboratory programmers. An advanced type of technology is emerging based on digitalization, as a computerized three-dimensional (3-D) model, additive manufacturing also called 3-D printing, allows formation of block pieces by adding material layer-by-layer. The additive manufacturing (AM) approach has offered extreme progress in the broad choice of distinct zones, permitting the production of fragments of all possible varieties of substances such as metal, polymer, ceramic, and composites. The significant goal of current the article is to recapitulate the recent scenarios including the imminent perspective of AM techniques and challenges in dentistry. Moreover, this article reviews the recent developments of 3-D printing advancements along with the advantages and disadvantages. Herein, various AM technologies comprising vat photopolymerization (VPP), material jetting, material extrusion, selective laser sintering (SLS), selective laser melting (SLM), and direct metal laser sintering (DMLS) technologies based powder bed fusion technologies/direct energy deposition/sheet lamination centered on binder jetting technologies were discussed in detail. This paper attempts to provide a balanced view by emphasizing the economic, scientific, and technical challenges and presenting an overview of methods to discuss the similarities based on the authors' continuing research and development.

The Influence of Dental Virtualization, Restoration Types, and Placement Angles on the Trueness and Contact Space in 3D-Printed Crowns: A Comprehensive Exploration

“…Regarding the design stage, digital software and artificial intelligence can greatly save time [27]. Whether using a CAD/CAM system (subtractive processing) or a 3D printer (additive processing), relative production time must be sacrificed in order to improve accuracy [28]. A particular breakthrough in improving performance would be how 3D-printing technology can place more objects on the same plane.…”

Mechanism and application of 3D-printed degradable bioceramic scaffolds for bone repair

“…71,82 Furthermore, the high processing temperature of SLS limits the incorporation of biomaterials into the scaffolds to fabricate bioceramic scaffolds that exhibit microstructural inhomogeneity. 83 Therefore, the SLS printing parameters need to be improved to obtain bioceramic scaffolds with optimal sintering results. Laser scanning speed (LS) and laser power (LP) are critical printing parameters for SLS.…”

Influence of Proteins and Building Direction on the Corrosion and Tribocorrosion of CoCrMo Fabricated by Laser Powder Bed Fusion

“…Traditional processes for manufacturing CoCrMo implants include casting, hot forging, and subtractive processes, which are associated with various drawbacks such as solidification defects, high cost, and limited flexibility in the personalization of the implants. Additive manufacturing (AM) has grown noticeably in importance for producing highly customizable implants . Over the past few decades, laser powder bed fusion (LPBF), also referred to as selective laser melting (SLM), has been one of the dominant AM methods for implant materials .…”

Over the past few decades, laser powder bed fusion (LPBF), also referred to as selective laser melting (SLM), has been one of the dominant AM methods for implant materials . It is well-known that the manufacturing method can be a decisive factor affecting the corrosion and tribocorrosion of CoCrMo alloys because it affects the microstructure, defects, and surface properties important for the corrosion and wear mechanisms. , In recent years, electron beam melting (EBM) has also gained prominence in the production of orthopedic implants.…”
