The Inconspicuous Nature of COVID-19 and its Impact to Dentistry
As we strive to cope with the universal impact COVID-19 has had on all of our lives, we are all trying to reach the same destination: arresting a global pandemic. However, though that goal is shared, the path to get there may be quite varied depending on the unique situation or environment. There is no question that the COVID-19 pandemic presents unique opportunities to take disruptive innovation to levels never imagined (or desired).1,2 In this essay, the authors present different perspectives based on their experiences in various dental health care settings, following their journey and the responses they orchestrated to ...

Ways and pathways of global orthodontic postgraduate education
Education is an ongoing and self-renewing enterprise between teacher, student, and a supportive structure (mainly institution but also industry) to improve patient health. The benefits of technology permeated the global postgraduate orthodontic curriculum, which is standardized where accreditation agencies exercise oversight. Innovations, publications and online information instantly connect teacher and student. However, core issues are far ranging. Key concepts of evidence-based personalized treatment remain associated with the achievement of Class I occlusion and compromised treatment lacks recognition because of insuffi...

Orthodontic Journals and Orthodontic Meetings: Prior to, during, and after the Pandemic
Orthodontic journals and meetings are now at a crossroads. The manner that we communicate information to our readers and present education need to be examined. Factors impacting upon optimal readership of orthodontic publications before, during, and after the pandemic are explored. The caveat is to look forward and present innovative rather than derivative solutions to communicating and educating our colleagues. Some suggestions are offered to maintain readership interest are made (Source: Seminars in Orthodontics)

Deep Overbite Correction: Biomechanics and Clinical Implications
The goal of this paper is to describe and discuss the clinical use of intrusion mechanics during orthodontic therapy. The biomechanics of the classic segmented intrusion arch is explored along with modification of the appliance design to intrude and retract anterior teeth simultaneously. The advantages and limitation of intrusion mechanics are presented and the side effects analyzed to avoid undesired tooth movement and optimize clinical outcomes. The implications for the esthetic of the smile and the retention of intrusion are also discussed. (Source: Seminars in Orthodontics)

Mechanical considerations for deep-bite correction with aligners
Correction of deep-bite malocclusions with aligners is challenging for orthodontists. This review is meant to help orthodontists improve their clinical success in treating deep-bite malocclusions with aligners. Biomechanical strategies for achieving deep overbite correction need to be adapted for use in patients treated with aligners. Virtual case setup, attachment design, elastics, and bite ramp utilization are discussed in order to better equip orthodontists with a new “best practices” paradigm.

Accelerated Orthodontic Tooth Movement: Recommendations for Clinical Practice
The goal of this paper is to assess the current scientific literature on accelerated tooth movement in orthodontics and present an evidence-based guide for clinical practice. The most popular procedures currently used for accelerating tooth movement are reviewed and an evaluation of the treatment outcome is presented. The potential risks and benefits of these procedures are discussed. This information will allow clinicians to choose among protocols that are available based on individual patient needs.

Biomechanical considerations for total distalization of the mandibular dentition in the treatment of Class III malocclusion
Class III malocclusions with mild to moderate skeletal discrepancies can be camouflaged by orthodontic tooth movement. Conventional methods using Class III elastics can correct Class III into Class I molar relationships. These mechanics show side-effects such as labioversion and intrusion of the maxillary incisors, extrusion of the maxillary molars, linguoversion and extrusion of the mandibular incisors, and intrusion of the mandibular molars along with flattening of the occlusal plane. Conventional mechanics can improve occlusal relationships and some profile esthetics but may produce detrimental smile esthetics by reduci...

Mechanics to Enhance Facial and Smile Esthetics
The objectives of this paper are: 1) to review the two main principles of a beautiful and youthful smile to guide the clinician to visualize the main esthetic goals of orthodontic treatment, and 2) to present two clinical situations where appropriate orthodontic mechanics were used to obtain optimal facial and smile esthetics results.

Biomechanical considerations for total distalization of the maxillary dentition using TSADs
Class II malocclusions have traditionally been treated as nonextraction, extraction, or orthognathic surgery depending on severity of the dental and skeletal discrepancies. To enhance function and improve esthetics with nonextraction treatment, functional appliances, tooth-borne molar distalization, and Class II elastics have been used, but they require patient cooperation and have drawbacks such as mesial movement of the anchor teeth, molar extrusion, and flaring of the incisors. Recently, with the application of temporary skeletal anchorage devices (TSADs) in patients with Class II malocclusions, clinicians have been abl...

The use of finite element analysis in dentistry and orthodontics: critical points for model development and interpreting results
This paper highlights common procedures for establishing a well-constructed FEA problem using a representative dental geometry and discusses how results can be interpreted to understand the validity of methods and the scope over which the results are valid. (Source: Seminars in Orthodontics)

Introduction
Twenty-five years ago, the first volume of Seminars in Orthodontics was launched, appropriately with the very first issue entitled “Biomechanics and Appliance Design”. It was guest-edited by my mentor, Dr. Robert J Isaacson, who passed away 2 years ago (September 2018). I am proud to say that I was actively involved in creating that issue and that I was able to work alongside Bob for 12 of the best years of my life. The cur rent issue on “Contemporary Topics in Biomechanics” is dedicated to him and to the other 3 notable male mentors who influenced my career decisions and the absolutely amazing life I have been abl...

Advanced Esthetic Laser Procedures in Orthodontic Practice
The use of a soft tissue laser will not only improve the quality and speed of orthodontic treatment, it can dramatically enhance final esthetic results. To optimize the speed of treatment, esthetic considerations should be considered as part of the initial diagnosis. Using a laser allows cleaner finish lines and reduces damage to the gingival crests, with faster healing and less discomfort when compared to more conventional techniques. Even when dealing with complex altered passive eruption cases, soft-tissue laser procedures can provide significant benefits to patients. (Source: Seminars in Orthodontics)

Laser Dentistry 101: An Introduction to Wavelengths and Laser-Tissue Interaction
Lasers are excellent devices that can add significant value to orthodontic practices. Orthodontists can now perform many procedures quickly, efficiently, and bloodlessly in their offices, instead of referring them back to the general practitioner, oral surgeon or periodontist. Many different laser devices are currently on the market, with purchase prices that vary from $5000 to well over $100,000. In order to understand how to use a laser, how a laser works on oral mucosa, and how to maximize use of this device in an orthodontic practice, it is critically important that the dentist understands the basics of laser-tissue in...

Basic Laser Procedures in Orthodontic Practice
Adding a soft tissue laser to an orthodontist's technology toolbox permits performance of numerous procedures that reduce time in treatment, save valuable chair time and improve results. It is critical to know both the abilities and limitations of the device in order to maximize benefits to both patient and practice, and realize an acceptable return on investment. Important considerations to understand when treatment planning for a laser procedure include the type of laser to use, levels of keratinized tissue, an understanding of biologic width and measurement of pocket depth.
