3D Metal Printing in Orthodontics: Current trends, Biomaterials, Workflows and Clinical Implications
Three-dimensional (3D) metal printing of customized orthodontic appliances is at the cutting edge of orthodontic technology. Different additive techniques, as well as materials, have been employed in order to directly 3D metal print an orthodontic appliance. The potential advantages of 3D metal printed appliances include greater treatment efficiency, increased patient's comfort, reduced orthodontic appointments, and reduced workflow steps, thus reducing the chances of error and resulting in a more accurate fit and better standardization.

3D printed aligners: Material science, workflow and clinical applications
Clear aligner orthodontic treatment is not a new treatment modality. Treatment with the use of plastic invisible removable appliances counts more than 80 years when Kesling introduced the tooth positioner, Sheridan introduced the Essix aligner and Align technology its aligners. In-house designing and aligner fabrication has been around for more than 10 years. The last years a digital techonological and material advancement has changed the process of aligner manufacturing from the plastic foil thermoforming procedure to a direct aligner printing one.

3D printing of in office custom-made brackets: Concept, Design, Production and Evidence
During the last few years, digital technology has been the main cause of many changes in dentistry and orthodontics. The ability to digitization of the oral cavity, the invention of CAD software, 3D printers, and printing materials helped the formation of the in-office designing and printing appliances concept. Fixed appliance customization on the other hand is a concept that could only be applied in special manufacturing companies. The installation of a digital laboratory in the orthodontic office allowed the production of customized fixed appliances. (Source: Seminars in Orthodontics)

Complex case treatment: Is there a limit for Surgery-first approach?
Are there any limits for Surgery-first approach? the article strives to identify the tenets of effective management of complex cases, such as facial asymmetry, with surgery-first approach. The main purpose of the article is in attempting to itemize prerequisites or determining factors, through various degrees of facial asymmetry severity, for the successful management of facial asymmetry cases. The key factors such as (1) assessment of chin deviation, (2) quantification or discernment of transverse occlusal plane canting, (3) spatial orientation evaluation of differential anterior and posterior region transverse occlusal c...

CAD-CAM workflows for palatal TAD anchored appliances
Mini-implants inserted in the anterior palate are showing the very high success rates of 91.5% - 99%. Compared to other insertion sites they can be used effectively for molar distalization, space closure, rapid maxillary expansion and protraction, molar intrusion and alignment of impacted upper teeth. In recent years, CAD-CAM techniques such as printed insertions guides and 3D metal printing were integrated into full digital workflows. These new procedures allow mini-implant insertion and appliance fitting in one appointment and may give orthodontists more confidence to insert in the optimum site. (Source: Seminars in Orthodontics)

Biomaterial testing in contemporary orthodontics: scope, protocol and testing apparatus
The domain of biomaterials as an entity encompasses a wide variety of materials that are found in nature and the surrounding environment. In line with the ever-increasing demand of biocompatible and esthetic alternatives, technology has evolved with contemporary times to list out a wide spectrum of substances1,2. Variations in their generative properties as well as their inherent range of actions provide the modern practitioner with a huge array of armamentarium to choose from3. It is in these widely-broadening landscapes that the field of Orthodontics is also engineered into to serve a variety of purposes. (Source: Seminars in Orthodontics)

Digital workflows in Orthodontic postgraduate training
Digital technology has completely reshaped the way we diagnose, treat, and follow-up our orthodontic patients. Tools such as digital models from intraoral scanners, 3D facial images and CBCTs have enlarged our diagnostic possibilities, still with some limitations. Following diagnosis, orthodontic treatments can now benefit largely from CAD/CAM approaches. These completely new workflows need to be integrated into postgraduate teaching, at the cost of certain challenges, which will be discussed. (Source: Seminars in Orthodontics)

The improved superelastic Ni-Ti alloy wire in orthodontic treatment: Characteristics and clinical application
Orthodontists usually use Ni-Ti alloy wires for leveling and aligning of teeth without bending the wire. However, Japanese Ni-Ti alloy wires, which are bendable and retain their unique characteristics even after bending, have been developed. After several decades, improved superelastic Ni-Ti alloy wires (ISW) were introduced and have been found to be useful in the leveling stage owing to their superelasticity, shape-memory effect, and low hysteresis. Moreover, despite its low stiffness, the ISW has been used in all treatment stages and in many cases, except in patients with a strong occlusal force and immediately before an...

Evaluating the accuracy of automated orthodontic digital setup models
Orthodontic tooth setup provides the orthodontist insight into the possibilities and limitations of treatment and enables visualization of the final goal of treatment. Lately, artificial intelligence techniques have been applied to the digital setup softwares to automate the process of tooth segmentation and alignment. The purpose of this study was to evaluate the accuracy and efficiency of automated digital setup softwares. The diagnostic digital impression data of 30 patients (mean age, 29.8 ± 14.4 y) who underwent non-extraction orthodontic treatment from 2020 to 2022 were collected. (Source: Seminars in Orthodontics)

Skeletal anchorage in Surgery First orthognathic surgery
Surgery First is an orthodontic technique, not a surgical technique, in which the orthodontic appliances are placed on immediately before surgery. The orthodontic dental decompensation is performed after surgery, being the orthognathic surgery itself fundamentally the same.Surgery First has several advantages for patients. For instance, the total treatment time drops significantly, and patients have better oral health-related quality of life scores during treatment.Several patients require skeletal anchorage miniplates for the post surgery orthodontic treatment.

Clinical Application of Clear Aligner Treatment (CAT) in the Surgery-First Orthognathic approach (SFOA)
Recent digital technological advancements in the orthodontic field, in general, and orthodontic-surgery domain, in specific, in terms of design, simulation, and fabrication of appliances have not only boosted the management of orthodontic practise, but also, has enhanced the streamlining of novel technique such as surgery-first orthognathic approach (SFOA). Currently, it is amply evidentiary to digitally simulate complex surgical movements, coordinate dental arches, and subsequently 3D-print thermoplastic splints as result of the digital simulation.
