- The hardest wordby Peter M. Greco on 01/03/2021 at 12:00 am
“Sorry seems to be the hardest word”Elton John (1976)If it werent for the delay in eruption of his mandibular canines, you would have never seen Steven. His mother was referred because she didn't trust the previous orthodontist, who claimed that Steven needed full orthodontic correction. Yet his occlusion requires minimal, if any, modification. The panoramic film discloses almost total root formation of both normally positioned mandibular canines. The left canine will soon emerge, and the right needs only minor soft tissue exposure to hasten its eruption.

- Corporate responsibility through apparent agency?by Laurance Jerrold on 01/03/2021 at 12:00 am
Orthodontics has been good to you. You've made a good deal of money and invested it wisely. One of your financial forays was buying a professional building you have named the “Mytown Smile Center” (MSC). You decided to create a multidisciplinary environment with cosmetic dentists, orthodontists, a plastic surgeon, an orthognathic surgeon, and anyone and everyone who has something to do with smiles. Your idea was a hit, every office is rented for top dollar, and you are the poster child of an entrepreneurial landlord.

- Authors’ responseby Oscar Stangherlin Gomes, Roberta Martinelli Carvalho, Renato Faco, Marilia Yatabe, Terumi Okada Ozawa, Hugo De Clerck, Hilde Timmerman, Daniela Garib on 01/03/2021 at 12:00 am
Thank you for your concerns regarding our article and for the pertinent questions. All patients in our study were treated at the same center, and preorthodontics were performed similarly in both groups. Most patients from both groups underwent rapid maxillary expansion (RME) before grafting. The age for secondary alveolar bone grafting (SABG) procedure was similar in both groups: during the late mixed dentition before cleft-side canine eruption. RME is not necessarily performed right before bone-anchored maxillary protraction (BAMP).

Thank you very much for reading and criticizing our study in such detail.1 Because measurements were taken from the same subjects from dependent groups, many genetic and even epigenetic factors were eliminated. When the simulation is made from dependent groups according to the effect width stated before, the following results are obtained. Probably, the situation you are criticizing may be due to other package programs or different factors.2-5

- Finite element analysis: Is it justifiable?by Manuel Lagravère on 01/03/2021 at 12:00 am
In recent years, more specifically in the recent months, I have received a large number of articles to review that rely on the finite element method (FEM) or finite element analysis (FEA) to study different matters related to orthodontics. Some of these are excellent works, but the vast majority are of very low quality and present neither a proper justification for using FEA nor a correct method of execution. Thus, I write this editorial to give some insight to researchers and clinicians who might be planning or attempting a study in which FEM is used as an analysis tool.

- In situ rotation surgery for correction of growing, inversely impacted maxillary central incisorsby Ruisi Shi, Zhifei Zhou, Pan Li, Liqiang Shi, Hua Sun, Yudi Bai on 07/02/2021 at 12:00 am
Treatment of an impacted incisor with a dilacerated root is challenging for clinicians because of the position of the impacted incisor, the abnormality of the root, unfavorable prognosis, and, especially, the long treatment duration. We report on 2 young patients who had inversely impacted maxillary central incisors with developing labially dilacerated roots. Both patients were treated by a novel surgical approach, in situ rotation, by which the crowns of the inversely impacted incisors were carefully rotated to a relatively normal position, whereas the apical location remained relatively unchanged.
