Abstract

Thank you for reading and evaluating our article. Regarding your first point, the lower bound was −0.33, and the upper bound was 1.32. We apologize for the typographical error in writing the bounds. Your second comment is interesting. We could not do any measurements on the first molars at the beginning of the treatment (T0) because the cephalometric radiographs were taken before starting the orthodontic treatment. So, there were no molar bands to be able to do any measurements on the first molars. We started the measurements on the first molars at the end of leveling and alignment phase and before starting the en-masse retraction phase (T1). When we first submitted the manuscript for review to the American Journal of Orthodontics and Dentofacial Orthopedics, we included a Table reporting the measurements before starting the en-masse retraction phase (T1), but 1 of the reviewers asked us to delete this Table to decrease the number of tables included in the article. We are happy to provide the measurements now so that you can see the exact amounts on the intrusion and distalization of the first molars at the end of the en-masse retraction phase.TableDescriptive statistics of the maxillary first molar positions in the horizontal and vertical planes at 2 assessment timesMeasurementsFlapless corticotomy groupTraditional corticotomy groupT1T2T1T2MeanSDMeanSDMeanSDMeanSDMUM-H (mm)42.326.2942.196.2042.225.2742.105.32MUM-V (mm)68.855.0468.204.9468.773.4368.103.45 Open table in a new tab Thank you very much for your important final point. When we did the statistical analysis for our study, we got 3 digits after the decimal point. So, the calculated value for the mean difference in the SNA angle at the end of en-masse retraction of maxillary anterior teeth (T2) was −0.445. We preferred to include only 2 digits after the decimal point; the final rounded value was −0.45. This is the same situation for the other mentioned variables in your query. Traditional vs flapless corticotomyAmerican Journal of Orthodontics and Dentofacial OrthopedicsVol. 160Issue 1PreviewAn article in the November 2020 issue of the American Journal of Orthodontics and Dentofacial Orthopedics by Khlef et al1 evaluated the efficacies of traditional corticotomy and flapless corticotomy in accelerating en-masse retraction. The authors assessed skeletal, dental, and soft-tissue variables, and the external apical root resorption of the maxillary anterior teeth. Full-Text PDF
