Rationale of Total Arch Intrusion for Gummy Smile Correction
Excessive gingival display during smile, also referred to as gummy smile, is often perceived as esthetically unpleasant. While different etiological factors are known to be associated with gummy smile, it eventually results from an imbalance between the dentoalveolar hard tissue and the covering soft tissue. There are a number of different approaches to gummy smile correction. They range from a relatively simple and quick injection of Botulinum-toxin in the hyperactive lip elevator muscles to more invasive procedures such as maxillary impaction by orthognathic surgery.

Maxillary incisor position-based orthodontic treatment with miniscrews
Traditionally, orthodontic diagnosis and treatment have primarily involved the assessment of skeletodental relationships, with a particular focus on the mandibular dentition. Recently the focus has shifted towards the maxillary incisors as a starting point for facial esthetics with growing demands for facial esthetics. Three-dimensional maxillary incisor position (MIP) plays a pivotal role in improving facial esthetics in smiling and resting positions. With the advent of miniscrews, biomechanical force application in orthodontic treatment has become simpler due to absolute anchorage. (Source: Seminars in Orthodontics)

TAD driven Class III Camouflage: Eight Point Protocol to Optimize Efficiency, Aesthetics and Stability
Although Class III malocclusions are the least frequent amongst sagittal malocclusions, they tend to be challenging to treat and more likely to need orthognathic surgery for the best treatment. The reported incidence of this malocclusion ranges below 20%, with Asian groups experiencing the greatest prevalence and Caucasian populations experiencing the lowest. Class III malocclusions can be divided into two groups: developing and non-developing. With children (ages 7 to 9) benefiting more orthopedically, early intervention is typically advised for Class III malocclusions that are still developing. (Source: Seminars in Orthodontics)

Asymmetric Dental-Alveolar Transversal Corrections with Skeletal Anchorage
Transversal asymmetries of the dental arches are common orthodontic problems. Significant asymmetries needed a surgical approach for their correction before the introduction of skeletal anchorage. This paper presents two different approaches to correct dental transversal asymmetries, using skeletal anchorage both directly and indirectly. The direct use of skeletal anchorage requires a careful planning of the desired dental movement and the estimation of the line of action of the needed force to achieve it.

Improved facial profile with non-extraction treatment of severe protrusion using TSADs
Extraction has traditionally been necessary to correct bimaxillary and lip protrusion with proclined maxillary and mandibular incisors. However, non-extraction treatment using temporary skeletal anchorage devices (TSADs) is now an option for severe overjet or full-step Class II malocclusions. It is possible to treat bimaxillary protrusion with non-extraction, but for successful non-extraction treatment in bimaxillary patients, the amount of total arch distalization of the mandibular dentition is crucial.

Torque and vertical control of maxillary incisors for an esthetic smile using TSADs implanted in various areas: Biomechanical considerations
Esthetic smiles are an increasingly important focus of orthodontic treatment. Factors related to maxillary incisors, such as smile arc, maxillary gingival exposure, and maxillary crown torque, are related to esthetic smiles. It is very important to consider these factors during orthodontic treatment. However, with conventional orthodontic treatment using traditional anchorage, torque and vertical control of maxillary incisors, which are closely related to esthetic smile, were significant challenges, but with the introduction of temporary skeletal anchorage devices (TSADs), control of maxillary incisors has become easier to...

Essential factors in developing an efficient in-office aligner system
Aligner therapy has significantly changed from its inception in the 1970s. Mass produced CAD/CAM aligner fabrication process transformed aligner treatment in early years of the 2000s. Multiple aligner systems are available to treat patients with various complexity of care. Advances in digital software packages to move teeth along with access to user-friendly desktop 3D printers incentivized providers to revisit fabricating aligner in-office. Hence the outset of an in-office aligner (IOA) system. (Source: Seminars in Orthodontics)

3D printing digitally planned in-direct bonding tray
Indirect bonding (IDB) of brackets was introduced over half a century ago. Orthodontists are polarized on adopting this technique mostly because of tedious process of fabricating trays and technique sensitive nature of this protocol. Integration of digital treatment planning software packages along with user-friendly desktop 3D printing solutions transformed the traditional IDB technique into the digital indirect bonding technique with 3D printed trays. The main advantages of digital IDB technique are positioning brackets based on a simulated treatment outcome and eliminating many tedious steps in fabricating IDB trays. (S...

Introduction
Over the past few decades, significant advances have been made in the application of 3D imaging and 3D printing technology in contemporary orthodontic practice. Techniques and protocols describing the application of digital technology in orthodontics are collectively called digital orthodontics. These protocols facilitate customization of therapeutic orthodontic devices. In addition to therapeutic orthodontic devices, other appliances like splints or indirect bonding trays are digitally designed by the orthodontist and fabricated using a variety of insourcing/outsourcing combinations.

Education using clear aligners and Digital workflows in Graduate Orthodontic Residency Programs
Traditional fixed appliances have had a long history of achieving predictable results in Orthodontics. However, the aesthetic limitations of fixed appliances during orthodontic treatment led to the creation of clear aligners. 1 Kesling first proposed the idea of using clear aligners to straighten teeth using a piece of flexible rubber from laboratory wax models of teeth.2 Limitations of the original idea were solved over the years by combining the clear aligner concept with interproximal tooth reduction (IPR) techniques.

The Application of In-office Aligners in the Combination Treatment Protocol
Orthodontists often choose either braces or clear aligners when treatment planning. However, with combination (combo) treatment, which uses both fixed and removable appliances for the same case, orthodontists take advantage of what each treatment modality does best. Fixed appliances provide initial forces to initiate orthodontic tooth movement, while removable devices administer the finishing stages.Technology for in-office clear aligner therapy improves the practice workflow for combo treatments.

Use of optical scanning and 3D printing to fabricate customized appliances for patients with craniofacial disorders
This paper presents a concept and methodology of biocompatible 3D printing in combination with intraoral and extraoral 3D surface scans for individualized appliances in patients with craniofacial disorders. The concept arises from the clinical problem of rapid growth and minimal compliance of infants with such disorder and the urgency to effectively treat the often severe, life-threatening symptoms such as airway obstruction. Methodology and interdisciplinary cooperation are explained in a real case of Pierre Robin sequence – infant with micrognathia and airway obstruction. (Source: Seminars in Orthodontics)
