- Class II malocclusion treatment with a customized dual force distalizerby Aron Aliaga-Del Castillo, Luciano Soldevilla, Marcelo Vinicius Valerio, Silvio Augusto Bellini-Pereira, Lorena Vilanova, Luis Ernesto Arriola-Guillén, Guilherme Janson on 28/07/2021 at 12:00 am
Intraoral distalizers associated with skeletal anchorage provide the major benefit of promoting molar distalization with minimum anchorage loss and patient cooperation. This case report presents the treatment of a 17-year-old female with Class II Division 2 malocclusion, maxillary dentoalveolar protrusion, mild mandibular retrusion, increased overjet, deepbite, and lip incompetence. The treatment plan involved initial maxillary molar distalization with a customized version of the skeletally anchored dual force distalizer (DFD).

- The clinical management of orthodontically-induced external root resorption: A questionnaire surveyby Scott Derek Currell, Peter Donald Blackmore Grant, Adrian Esterman, Alan Nimmo on 25/07/2021 at 12:00 am
With more dentists performing orthodontics, identifying and managing patients at risk or affected by orthodontically-induced external root resorption (OIERR) is paramount.
- A surgery-first approach using single-jaw rotational mandibular setback in low-angle mandibular prognathismby Gyeong-Su Kim, Sung-Hoon Lim, Seo-Rin Jeong, Jae Hyun Park on 14/07/2021 at 12:00 am
For the treatment of low-angle mandibular prognathism, rotational mandibular setback surgery is usually performed with Le Fort I maxillary osteotomy to rotate the maxillomandibular complex simultaneously. However, this maxillary surgery can be replaced with the orthodontic intrusion of maxillary posterior teeth. Single-jaw rotational mandibular setback surgery can be done with a surgery-first approach by planning orthodontic rotation of the maxillary occlusal plane with the simulation of the postsurgical forward mandibular rotation.
- Retrospective comparison of dental and skeletal effects in the treatment of Class II malocclusion between Herbst and Xbow appliancesby Natalia Martins Insabralde, Marcio Rodrigues de Almeida, Renata Rodrigues de Almeida-Pedrin, Carlos Flores-Mir, José Fernando Castanha Henriques on 14/07/2021 at 12:00 am
The purpose of this research was to compare dentoskeletal changes produced by Herbst and Xbow appliances in late mixed/early permanent dentition patients with Class II Division 1 malocclusion to an untreated control group.
- Occlusal stress distribution in the human skull with permanent maxillary first molar extraction: A 3-dimensional finite element studyby Safiya Sana, Rony T. Kondody, Ashok Kumar Talapaneni, Asma Fatima, Sayeeda Laeque Bangi on 14/07/2021 at 12:00 am

- Where is the center of resistance of a maxillary first molar? A 3-dimensional finite element analysisby Vaibhav Gandhi, Bill Luu, Rebecca Dresner, David Pierce, Madhur Upadhyay on 13/07/2021 at 12:00 am
The center of resistance (CRes) is regarded as the fundamental reference point for predictable tooth movement. Accurate estimation can greatly enhance the efficiency of orthodontic tooth movement. Only a handful of studies have evaluated the CRes of a maxillary first molar; however, most had a low sample size (in single digits), used idealized models, or involved 2-dimensional analysis. The objectives of this study were to: (1) determine the 3-dimensional (3D) location of the CRes of maxillary first molars, (2) evaluate its variability in a large sample, and (3) investigate the effects of applying orthodontic load from 2 directions on the location of the CRes.

Thank you for taking an interest in our article and for your thoughtful comments. We agree with your thoughts regarding the shortcomings of our published method; the report was one of our initial attempts at using nasoalveolar molding aligners, and we have been making efforts to refine, simplify, and optimize our approach since then.
- Diversity, engagement, and inclusion: The great joys of teachingby Eric Ploumis on 01/07/2021 at 12:00 am
I have been a clinical instructor of orthodontics at New York University for over 30 years. Participating in this diverse and stimulating environment has been immensely satisfying. Among the many benefits of the graduate program is interacting with a broad universe of students, faculty, staff, and patients. Teaching in this environment has taught me as much as I have taught my students—lessons that aren't in any textbook and have nothing to do with clinical skills.

Thank you for reading and commenting on our article. The article you cite by Chate1 is a valuable article about the effect of using special disinfectants on reducing biofilm in the waterline of dental units. In our article, if we meant flushing without disinfectant, we would use the phrase “flushing without disinfectant,” as Chate1 did in his Conclusions. This sentence is written under the “disinfection and sterilization” section, and flushing without disinfectants was not mentioned. According to the new Centers for Disease Control and Prevention guidelines, flushing alone cannot be relied on as the only way to improve the unit's water quality.
- More ways than oneby Peter M. Greco on 01/07/2021 at 12:00 am
You truly enjoy the Tuesdays you devote to teaching at a local university. Despite the numerous continuing education courses you've completed, your experience as a part-time educator has enriched your knowledge more than you could ever imagine. As you've often said to your residents, their interaction with you gives you much more than you bring to them. And the best residents are those who are insatiable when it comes to knowing why, when, and how. But you notice an increasing trend over the years you've been teaching.

- The sins of the pastby Laurance Jerrold on 01/07/2021 at 12:00 am
Wolf v Rothstein, No. 26859 (Ohio Ct. App. Second Dist., August 19, 2016) presented an all too common scenario. The defendant, an employee of a surgical group, performed surgery on the plaintiff that did not end well. The plaintiff filed suit claiming negligence and lack of informed consent on the part of the surgeon; and negligence in overseeing the defendant surgeon by the surgical group that employed him. This article will only deal with the issue of the plaintiff’s motion to the court to be allowed to present evidence of a number of other malpractice suits that the defendant had been the subject of as well a number of proceedings by the state medical board concerning the defendant’s past practice history.

The understanding of how orthodontic movement of the teeth can assist other dental specialties and benefit the patients should be a major concern of orthodontic clinicians and researchers, hence the prominent role of the articles published by the American Journal of Orthodontics and Dentofacial Orthopedics over more than 100 years. The critical analysis of these papers contributes to the improvement of scientific evidence associated with the American Journal of Orthodontics and Dentofacial Orthopedics content.

- Correction of a gummy smile and lip protrusion by orthodontic retreatment with lingual appliances and temporary skeletal anchorage devicesby Ryoon-Ki Hong, Jang-Hoon Ahn on 30/06/2021 at 12:00 am
A 28-year-old woman desired orthodontic retreatment for lip protrusion and excessive gingival display in both the anterior and posterior areas on full smiling. She had previously undergone an extraction orthodontic treatment for correction of open bite. She was diagnosed with skeletal Class Ⅱ hyperdivergence. To mimic LeFort Ⅰ maxillary impaction surgery, posterosuperior movement of the maxillary whole dentition was planned, and bodily distalization of both the maxillary and the mandibular whole dentitions to improve lip protrusion.

Extreme patterns of vertical facial divergence are of great importance to clinicians because of their association with dental malocclusion and functional problems of the orofacial complex. Understanding the growth patterns associated with vertical facial divergence is critical for clinicians to provide optimal treatment. This study evaluates and compares growth patterns from childhood to adulthood among 3 classifications of vertical facial divergence using longitudinal, lateral cephalograms from the Craniofacial Growth Consortium Study.

- Canine avulsion: An extreme complication of a fixed mandibular lingual retainerby Parmjit Singh on 23/06/2021 at 12:00 am
The use of fixed retainers at the end of a course of orthodontic treatment has become standard practice. The main complication that can occur with fixed retainers is the detachment of the wire from one or more teeth. A less common complication is unwanted tooth movement. This article presents a patient with extreme tooth movement associated with a mandibular fixed retainer. Ten years after orthodontic treatment, a 26-year-old male sought treatment for post-orthodontic movement of the mandibular anterior 6 teeth.
