3D Printing Part 1 - A History and Literature Review Of 3D Printing in Dentistry

Abstract

Introduction: The term 3D printing is commonly used to depict an assembling method whereby the final form of an object is the result of the addition of different layers to build the frame of an object. This procedure is more accurately portrayed as additive manufacturing and is likewise alluded to as fast prototyping. The term 3D printing, in any case, is generally new and has been an active part of current developments in Dentistry. Much publicity encompasses the evolution of 3D printing, which is hailed as an innovation that will perpetually change CAM manufacturing, including in the dental sector. This review is the first part in a 3D Printing series that looks at the history of 3D Printing, the technologies available and reviews the literature relating to the accuracy of these technologies. Conclusions: The recent advancement in digital dentistry to incorporate these tools has modernised dental practices by paving the way for computer-aided design (CAD) technology and rapid prototyping. The use of 3D printing has led to 3D digital models produced with intraoral scanners (IOS), which can be manipulated easily for diagnosis, treatment planning, mockups, and a multitude of other uses. Combining 3D Printing with a 3D intraoral scan eliminates the need for physical storage but makes it to retrieve a 3D models for use within all dental modalities.

A Review of the Stereo lithography 3D Printing Process and the Effect of Parameters on Quality

“…Polymers make up the majority of the 3D printing materials used in dental restorations, which replace lost teeth and tooth structure. In contrast to ceramics and metals, the chemical and physical properties of polymers are characterized by elasticity and tensile strength, which may offer the high-performance and longlasting qualities required for use as a dental restorative material [11]. The transverse strength and elastic modulus of the resin were both significantly impacted by a change in the polymerization temperature [17].…”

“…Threedimensional printing technology have created a variety of dental prosthesis using polymer materials in orthodontic treatment, including denture bases, fake teeth, temporary crowns, bridge and crown facings, and implant caps. Studies have shown that polymers are used in 3D printing technology for dental applications, such as the manufacturing and intervention of implant fixtures, maxillofacial reconstruction, and metal bridges [11]. The majority of resin compositions contain inert dyes, which absorb incoming light and improve polymerization control.…”

“…Based on computer-aided design (CAD) digital model, a group of techniques that permit the layer by layer construction of complex 3D shapes out of a variety of standardized materials, including solid, liquid, and powder [1,2]. The flexible design of such a process increases its capacity for manufacturing a wide range of functional products [3]. Additionally, it can quickly produce one-off and small-batch components, fresh samples, and goods with complicated shapes, molds, and models [4].…”

“…An increasing number of materials have been created by SLA for a wide variety of applications, including soft robotic actuators, sensors, microfluidics devices and energy storage components [1,10]. Medical implants are the most important applications of SLA such as dental prostheses [11]. This review discusses the stereo lithography process including its technology, material overview, advantages, disadvantages, SLA printer parameters.…”
