Regarding a recent publication in the February issue of the American Journal of Orthodontics and Dentofacial Orthopedics (Moradinejad M, Yazdi M, Chaharmahali R, Araghbidikashani M, Bagheri S, Rakhshan V. Efficiency and side effects of a novel method for maxillary central root torque (a horizontal box loop of round wire) in comparison with the conventional rectangular wire: a finite element study. Am J Orthod Dentofacial Orthop 2022;161:e172-86), we would like to congratulate the authors on their interesting study; however, we also raise several questions.
- Direct printed removable appliances: A new approach for the Twin-block applianceby Simon Graf, Nour Eldin Tarraf, Sivabalan Vasudavan on 01/07/2022 at 12:00 am
Removable appliances are an important part of orthodontic treatment. The Twin-block is widely used for Class II correction. Traditionally, an impression, bite registration, and mounted plaster casts are required to fabricate the acrylic appliance, which usually requires a specialized laboratory. This makes the process expensive and also time-consuming.This paper aims to present an innovative approach for the virtual design and direct printing of removable orthodontic appliances, particularly the Twin-block, that can be done in-office without the need for casts or a specialized laboratory.
- Systematic reviews in orthodontics: A fresh look to promote renewal and reduce redundancyby Declan T. Millett, Philip E. Benson, Susan J. Cunningham, Grant T. McIntyre, Padhraig S. Fleming, Farhad B. Naini, Aliki Tsichlaki on 01/07/2022 at 12:00 am
Systematic reviews are intended to collate and analyze the evidence regarding a specific aspect of clinical practice in a drive for evidence-based health care.1 Unfortunately, many systematic reviews in medicine and dentistry2,3 conclude by stating that further evidence is required through well-designed randomized clinical trials.4-6 It has been mooted that within orthodontics, systematic reviews considerably outweigh the number of clinical trials7 with evidence that a substantial proportion of the former is limited or inconclusive.

- Crazy 8’sby Laurance Jerrold on 01/07/2022 at 12:00 am
One of our readers called me the other day and posed an interesting question. He opined that it might be of interest to the rest of you, so I decided to share both his query and my response.Larry: The other day I interviewed for the clinical director’s position of a large multi-office practice (20+ offices). The owner told me that none of the doctors were permitted to order the extraction of third molars because if something went wrong regarding the extractions, then the orthodontist who made the referral as well as he, the owner/employer, could potentially incur some degree of liability; something he did not wish to expose himself to.
- Missing data, part 2. Missing data mechanisms: Missing completely at random, missing at random, missing not at random, and why they matterby Tra My Pham, Nikolaos Pandis, Ian R. White on 01/07/2022 at 12:00 am
In the first article,1 we demonstrated that any analysis with missing data makes untestable assumptions about the missing values. The use of different statistical methods rests on different missing data assumptions, and it is important to be transparent about which assumption we are making when implementing a given method. As we will see in article 5, multiple imputation,2 a popular approach for handling missing data, is typically performed assuming data are missing at random (described below).
- Effect of pulsed electromagnetic field on the duration of orthodontic treatmentby Nida Nayyer, Jitendra Sharan, Ashok Kumar Jena on 01/07/2022 at 12:00 am
We congratulate the authors for their investigation exploring the utility of pulsed electromagnetic field in accelerating orthodontic tooth movement (Bhad Patil WA, Karemore AA. Efficacy of pulsed electromagnetic field in reducing treatment time: a clinical investigation. Am J Orthod Dentofacial Orthop. Epub 2022 Jan 15). We seek to clarify a few aspects of the investigation that may add value to the current study and future studies on the subject.
- Fundamental consistencyby Peter M. Greco on 01/07/2022 at 12:00 am
You would call Dr Scott your A-level referrer. She’s your town’s most acclaimed pedodontist, does little tooth movement herself, and as far as you know, sends you the majority of her patients who need orthodontic treatment. But the parents of almost every young patient referred by Dr Scott mention that they were told that their child is tongue-tied and requires a lingual frenectomy as soon as possible. You know that the topic of frenectomies for ankyloglossia is controversial, as confirmed by your recent review of the literature and via your communication with your dental and medical colleagues.

- An unusual extraction pattern for retreatment in a patient with dental protrusion and a deficient soft-tissue chinby Johnny J.L. Liaw, Shin Huei Wang, Betty M.Y. Tsai on 23/06/2022 at 12:00 am
A patient with dental protrusion and deficient soft-tissue chin, previously treated with maxillary first premolar extraction, sought retreatment to improve his facial profile. Orthognathic surgery was proposed as the ideal treatment option, but the patient declined. Therefore, other orthodontic options were considered. The combined intrusion and retraction force systems supported with skeletal anchorage on both arches and a midpalatal miniscrew successfully reduced the protrusion and rotated the mandible counterclockwise to improve the facial profile and chin projection.

Optimal treatment for an adult patient with hyperdivergent facial morphology, Class III malocclusion, bilateral posterior crossbite, and skeletal disharmony usually requires comprehensive orthodontics combined with extractions, orthognathic surgery, or both. However, treatment becomes more challenging when the patient rejects surgery because of fear or cost. This case report presents the orthodontic treatment of a 24-year-old woman with a Class III malocclusion and bilateral posterior crossbite without surgery using orthopedic and comprehensive orthodontic approaches.
- Stability of first and second premolars extraction space closureby Guilherme Janson, Mayara Rizzo, Marcelo Vinicius Valerio, Rodrigo Oyonarte, Daniela Garib on 06/05/2022 at 12:00 am
Premolars are the teeth most often extracted to provide space to correct crowding, excessive dental and/or labial protrusion, and to compensate for the sagittal discrepancy. After treatment, the extraction spaces have to remain closed. Nevertheless, several studies have shown a tendency for some relapse even in patients finished with an adequate occlusion. Thus, the objective of this study was to compare the stability of extraction space closure of the first and second premolars.
