We thank Drs Kailasam, Jagdish, and Chitharanjan for taking a keen interest in our article, “Comparative assessment of alignment efficiency and space closure of active and passive self-ligating vs conventional…
Self-ligation and faster treatment time—a myth?
We read with great interest the article in the May issue entitled “Comparative assessment of alignment efficiency and space closure of active and passive self-ligating vs conventional appliances in adolescents:…
Three-dimensional cephalometric superimposition of the nasomaxillary complex
Introduction Two-dimensional maxillary superimposition techniques have been routinely used in clinical practice, but a 3-dimensional plane has yet to be introduced and validated. The purposes of this study were to…
Adverse responses to products or treatments
Orthodontists are blessed in many ways. One of our blessings involves the safety and high quality of the products that are now available for our use. Another is the relative…
Interpretation of observational studies
Ideally, the objective of a clinical trial is to determine with a high degree of certainty whether the intervention of interest is truly effective. In high-quality randomized trials, if the…
Dimensions of central incisors, canines, and first molars in subjects with Down syndrome measured on cone-beam computed tomographs
Introduction The literature on tooth dimensions in subjects with Down syndrome (DS) is scarce. To our knowledge, no studies have yet been published in which the morphometry of the teeth…
Surgically assisted rapid maxillary expansion: Cone-beam computed tomography evaluation of different surgical techniques and their effects on the maxillary dentoskeletal complex
Introduction The aims of this study were to evaluate and compare skeletal, dentoalveolar, dental, and periodontal changes in surgically assisted rapid maxillary expansion (SARME) patients with and without pterygomaxillary disjunction….
Three-dimensional monitoring of root movement during orthodontic treatment
Introduction A significant objective of orthodontic treatment is to achieve proper and stable tooth positions that involve not only the crowns, but also their roots. However, the current methods of…

Fundamentals of orthodontic treatment mechanics
The coauthors of Fundamentals of Orthodontic Treatment Mechanics are eminent figures in orthodontics: Drs John Bennett and Richard McLaughlin. Their book covers all aspects of the “McLaughlin Bennett System 4.0,”…
Interexaminer and intraexaminer reliabilities of 3-dimensional orthodontic digital setups
Introduction The use of digital orthodontic setups has grown quickly. The purpose of this study was to test the interexaminer and intraexaminer reliabilities of 3-dimensional orthodontic digital setups in OrthoCAD…
Separate but equal
“One way or another, I’m gonna find ya, I’m gonna getcha getcha getcha getcha…” So begins Debbie Harry’s hit song “One way or another.” It started me thinking about the…
Variability of the inclination of anatomic horizontal reference planes of the craniofacial complex in relation to the true horizontal line in orthognathic patients
Introduction The purpose of this study was to assess the reliability of the Frankfort horizontal (FH), sella-nasion horizontal, and optic planes in terms of their variabilities in relation to a…
A more accurate soft-tissue prediction model for Class III 2-jaw surgeries
Introduction The use of bimaxillary surgeries to treat Class III malocclusions makes the results of the surgeries more complicated to estimate accurately. Therefore, our objective was to develop an accurate…
Treatment outcomes after extraction and nonextraction treatment evaluated with the American Board of Orthodontics objective grading system
Introduction A controversy exists regarding better treatment outcomes when patients treated with extractions and without extractions are evaluated. The aims of this study were to use the American Board of…
