Appreciation of the soft-tissue profile is important in orthodontic diagnosis and treatment. However, are the patients themselves aware of their profile appearance? We aimed to evaluate if age influences self-perception of the soft-tissue profile in children.

This article reports the interdisciplinary treatment of a girl born with a complete bilateral cleft lip and palate. She had congenitally missing maxillary lateral incisors and canines and mandibular incisors, canines, and second premolars in addition to third molars. At age 11 years 2 months, she was treated with rapid maxillary expansion followed by bonding of the maxillary arch. Cranial harvested alveolar bone graft surgery was done at age 17 years 2 months. Mandibular arch treatment was started at age 19 years using single tooth implants initially as orthodontic anchorage devices and secondarily as prosthetic abutments.

Recently, an abundance of case presentations, clinician's corner articles, and opinion pieces have appeared in professional periodicals and regional orthodontic journals, which, coupled with the flooding swamp of related entries on social media, solidifies the impression that the do-it-yourself method of fabricating orthodontic appliances through 3-dimensional (3D) printing is the dominant trend in appliance fabrication. Interestingly, the apparent contradiction between the large quantity of information on this topic and the striking absence of evidence published in the scientific literature on the properties of printed utilities and auxiliaries, their intraoral aging profile, as well as the release of compounds in vitro or in vivo, has not been brought into the discussion yet.

Thank you for your interest in our article. We appreciate your comments and questions, which contributed to the revision of the statistical analysis.

We appreciate the comments raising several questions. We hope that our reply will prompt the readers to consider the best treatment option for each patient in the future.

Your relationship with Dr Green seemed to be a throwback from the good old days. Aside from 1 other orthodontist in the vicinity, you and Green were the only orthodontists within a 15 mile radius 20 years ago. However, no competition rose between you, and you shared an enduring trust and respect for quality from referring dentists. You covered each other's offices when either of you were absent from the office. In the few instances of second opinion consultations between your 2 offices, you were equally respectful of the perspective that there are more ways than 1 to treat a malocclusion.

The authors are to be commended for accepting the error in the text and submitting their raw data. I have reviewed the data and now have additional concerns.

Correction to: Costa MVC, Calderan MF, Cruvinel T. Could orthodontic fixed appliances and excess weight affect gingival health in adolescents? Am J Orthod Dentofacial Orthop 2020;157(2):172-7.

I read with great interest the paper by Costa et al (Costa MVC, Calderan MF, Cruvinel T. Could orthodontic fixed appliances and excess weight affect gingival health in adolescents? Am J Orthod Dentofacial Orthop 2020;157:172-7). The authors conclude that weight, as assessed specifically by body mass index, is related to gingival inflammation. Their results include a scatter plot of body mass index (%) variation with the gingival index and a very high correlation coefficient between these variables (ρ = 0.97, P <0.001).

Thank you, Dr Halazonetis, for your interest in our article. We appreciate the comments and questions, which have contributed to our revision of the statistical analysis and interpretation of these results.

An article published in July 2020 by Massaro et al shows a case of an 8-year-old boy in the early mixed dentition with Class II, Division 2 malocclusion, and ectopic eruption of the mandibular right lateral incisor. (Massaro C, Janson G, Yatabe M, Calil L R, Marchini T O, Garib D. Dental anomaly pattern and multiple ectopic teeth. Am J Orthod Dentofacial Orthop 2020; 158:102-113).

There is evidence that studies that report statistically significant results are more likely to get published compared with studies with nonsignificant results.1 Systematic reporting of studies on the basis of the direction and size of the results is a threat to the integrity of systematic reviews because it can lead to biased treatment effects.1 The potential bias emerging from such practices is known as publication bias and falls under the reporting bias umbrella. There is a preponderance of publication with statistically significant results across fields, including dentistry and orthodontics.

Your patient's particular condition could have been treated in one of a few different ways. However, from your perspective, there was only 1 clear way. So, when it came to the informed consent discussion, you did everything you were supposed to. You, or your treatment coordinator, informed the patient what their particular problem was, how you recommended treating their condition, why you were proposing whatever it was you were proposing, and the risks and benefits of the procedure you were recommending, along with the administrative requisites (time, money, appointments, etc.), and finally offered to answer any questions the patient might have.

An article published in July 2020 by Okihara and Onoto shows a case of a 21-year-old woman exhibiting maxillary anterior crowding, deviation of the maxillary midline, and deeply impacted mandibular second molars bilaterally with Class II malocclusion (Okihara H, Ono T. Correction of bilateral heavily impacted second molar with improved super-elastic nickel-titanium alloy wires. Am J Orthod Dentofacial Orthop 2020;158:114-25).

A request was submitted by a member of the American Association of Orthodontists for an assessment on efficacy and current evidence on accelerated tooth movement approaches by the Rapid Assessment of Evidence Panel (RAE) of the American Association of Orthodontists Foundation. The RAE panel undertook a review of current evidence on the efficacy of accelerated tooth movement approaches such as piezocision, corticotomies, photobiomodulation, and a wide variety of surgically assisted approaches. The primary outcomes examined in the review included: tooth movement (typically canine retraction within the first 3 months) after interventions for accelerated tooth movement and duration of orthodontic treatment.

Surgically assisted rapid maxillary expansion is a widely used surgical procedure for resolving transverse maxillary occlusal changes in patients with bone maturity. However, few studies about the postoperative morphologic alterations in the nasal cavity in its inferior portion and the nasal septum positioning exist.

To evaluate the influence of compensatory tipping of maxillary and mandibular incisors on the anterior arch length ratio and canine relationship in skeletal Class II malocclusion.

Patients undergoing clear aligner therapy (CAT) report muscle tenderness and produce wear facets on their aligner trays. However, little is known about the masticatory muscle response to clear aligners. Here, we measured the activity of the masseter during CAT using ambulatory electromyography. We also explored whether psychological traits modulate the masticatory muscle response to CAT.

This study aimed to associate 2 indexes for evaluating malocclusion in the mixed dentition.

This research aimed to determine whether Class II malocclusion can be treated with clear aligners after completing treatment with the initial set of aligners.

Computer-aided design and manufacturing (CAD-CAM) systems have assisted orthodontists to position brackets virtually. The purpose of this study was to evaluate if a CAD-CAM system could predict the orthodontic treatment outcome of patients with Angle Class I malocclusion with mild crowding or spacing and with no need for orthodontic extraction.

The purpose of this clinical report is to illustrate an innovative treatment plan for a patient with Class III malocclusion. The plan combined the versatility of computer-aided design and manufacturing technology with miniscrews. Maxillary and mandibular fully customized metal framework anchored to 4 miniscrews was digitally designed and constructed for a growing patient with midface hypoplasia and a skeletal Class III malocclusion. The patient wore Class III elastics between hooks on the maxillary and mandibular frameworks full time for 10 months.

Structural or anatomic differences may arise during the development of the maxillary sinus and the process of fusion of the palate in the presence of cleft lip and palate. The present study aimed to compare the maxillary sinus volume of patients with unilateral cleft lip and palate and a control group (noncleft patients).

The primary objective of the study was to quantitatively analyze the width and height of the mandibular buccal shelf area (MBS) at 3 different potential locations for mini-implant placement. In addition, we aimed to compare and contrast the bone parameters of the MBS to study the correlation between different growth status (growing or nongrowing), facial types (hypodivergent, normodivergent, and hyperdivergent), and sex differences (male or female).
