“…To introduce this technique, the polymer cantilever should have similar mechanical properties to TMA alloys. According to Guerrero-Gironés et al, the assessment of the biocompatibility of 3D printing and conventional resins revealed no major differences [ 70 ]. Possibility to produce the tooth-shade or transparent cantilevers would increase aesthetics.…”

Cantilevers: Multi-Tool in Orthodontic Treatment

This review aims to discuss and illustrate various uses of cantilevers to solve multiple clinical issues and prove their versatility. Cantilevers are commonly used in the segmented arch technique, and they can be designed to solve various clinical problems with highly predictable results. Its design and shape can modify the various combinations of vertical and horizontal forces. The novel trend is to combine cantilevers with skeletal anchorage. Cantilevers offer a very simple and statically determined force system. The advantage is the control over side effects, which normally occur on the anchor teeth and the occlusion. The disadvantages include possible side effects on the anchorage unit, when the anchorage is poorly controlled. The review highlights the clear benefits of cantilever use in complex corrections of single teeth, segments, and entire arch with a diminished effect on the dentition, also with the use of skeletal anchorage. With their simple and easily tailored design, these springs can be called an orthodontic multi-tool.

“…To evaluate the metabolic activity of the cells, various biological tests, including cell movement assays, cell apoptosis, scanning electron microscopy (SEM) and formation of intracellular reactive oxygen species (ROS), were conducted. The study concluded that except Freeprint Splint, which was highly cytotoxic to hGFs, the biocompatibility of the traditional resin and the resin used in 3 D Printing was comparable (Guerrero-Gironés et al , 2022).…”

“…3D printable splint materials are anticipated not to drain out any hazardous toxins that could cause unpleasant systemic or local reactions and not induce any emergent problems as an intra-oral equipment material (Iijima et al , 2015). Guerrero-Gironés et al (2022) evaluate and contrast the in vitro biocompatibility of advanced resins for dental splints (NextDent Ortho Rigid, Free print Splint and keysplint Soft from Keystone Industries, Detax and Detax, respectively), as well as conventional resins (Orthocryl, Dentaurum). Standard disc extractions of the inspected materials were created.…”

Purpose This study aims to cover the overall gamut of rapid prototyping processes and biomaterials used for the fabrication of occlusal splints in a comprehensive manner and elucidate the characteristics of the materials, which are essential in determining their clinical efficacy when exposed to oral surroundings. Design/methodology/approach A collective analysis of published articles covering the use of rapid prototyping technologies in the fabrication of occlusal splints, including manufacturing workflow description and essential properties (mechanical- and thermal-based) evaluation of biocompatible splinting materials, was performed. Findings Without advances in rapid prototyping processes and materials engineering, occlusal splints would tend to underperform clinically due to biomechanical limitations. Social implications Three-dimensional printing can improve the process capabilities for commercial customization of biomechanically efficient occlusal splints. Originality/value Rapid technological advancement in dentistry with the extensive utilization of rapid prototyping processes, intra-oral scanners and novel biomaterial seems to be the potential breakthrough in the fabrication of customized occlusal splints which have endorsed occlusal splint therapy (OST) as a cornerstone of orthodontic treatment.

“…They have been used chiefly for interim prostheses and flippers for surgical and occlusal guides. Its clinical applications also extend to working models and main applications in the fields of oral implantology, with the benefits of high material utilization (Guerrero-Girones et al 2022) and the ability to manufacture complex geometries (Shen et al 2020). Nevertheless, 3D printing has expanded to more permanent applications as the technology and materials developed.…”

Change in our world is happening quickly. For dentistry, this is no exception, and now is the time to foster new opportunities. Advances in the foundational science of dental, oral, and craniofacial health are expanding and enabling personalized care built on strong discoveries in the fields of microbiology, immunology, and neuroscience. Digital communication through electronic health records, patient portals, and teledentistry is emerging as vital new armamentarium for contemporary dental practice. Wearables linked with smartphone apps are trending to monitor pain levels, postoperative symptoms, wound healing, and home oral health habits. Oral fluid diagnostics are rapidly surfacing for use in diagnostics, drug testing, and hormone detection. Manipulation of the oral microbiome is under investigation for caries management and for potential impact on systemic conditions. Resolving mediators of inflammation are promising for addressing the chronic inflammation that plagues periodontal patients. New imaging modalities paired with digital approaches and 3-dimensional printing are formulating disruptions in the technical aspects of dentistry. Augmented reality and virtual reality are providing great potential as teaching tools for dental students and bear promise for lifelong learning for providers. Optimization of information technology and the incorporation of data science partnered with artificial intelligence and machine learning to improve patient care in a learning health care system approach will benefit large numbers of patients. These are exciting times for our profession, yet we need to navigate these paths carefully. Technology needs to significantly and positively change the experience of those involved (patients, dentists, staff, payors). New technologies need to be backed with solid research and implementation science. Automation should focus on improving care with attention to expanding care to the underserved and not lose the critical human connection that our patients need. There is great potential in the emerging innovations yet also great responsibility to ensure they are evidence based on rigorous science and deployable with equity and sensitivity. Knowledge Transfer Statement: This article discusses innovations in technology and treatments that have enormous potential to revolutionize our dental care, including novel concepts in electronic health records, communication between dentists and patients, biologics around diagnosis and treatment, digital dentistry, and, finally, the real-time optimization of information technology. The early implementation and validation of these innovations can drive down their costs and provide better dental and medical services to all members of our society.
