Evaluation of current additive manufacturing systems for orthodontic 3-dimensional printing
Introduction The objective of this research was to evaluate and compare linear and surface accuracy of dental models fabricated using 3 different vat photopolymerization printing units: digital light synthesis (M2 Printer;…
Comparative finite element analysis of bracket deformation in tie wings and slot region during simulated torque
Introduction Torque in orthodontics is the activation of the archwire for the third-order movement of teeth. During this force transfer mechanism from the twisted archwire, the bracket is prone to…
Missing participant outcome data in meta-analysis. Part 2
Modeling missing participant outcome data (MOD) in a meta-analysis has been advocated as conceptually and statistically advantageous to methods that manipulate the data before analysis by imputing or excluding MOD….
Retrospective comparison of dental and skeletal effects in the treatment of Class II malocclusion between Herbst and Xbow appliances
Introduction The purpose of this research was to compare dentoskeletal changes produced by Herbst and Xbow appliances in late mixed/early permanent dentition patients with Class II Division 1 malocclusion to…
Nasal cavity structural anomalies in children and adolescents at high risk of sleep-disordered breathing: An exploratory cone-beam computed tomography study
Introduction In this study, we investigated the presence of structural anomalies in the nasal cavity (deviated nasal septum [DNS] and turbinate hypertrophy [TH]) in patients at high risk or not…
Dental age estimation of young subjects with unilateral palatally displaced canine teeth
Introduction Delayed tooth eruption is often seen in patients with palatally displaced canines (PDC), but there is controversy over whether tooth formation is also delayed. This study attempts to elucidate…
Effect of microimplant assisted rapid palatal expansion on bone-anchored maxillary protraction: A finite element analysis
Introduction This study aimed to evaluate the craniofacial effects of microimplant assisted rapid palatal expansion (MARPE) on bone-anchored maxillary protraction (BAMP) through a finite element analysis. Methods A 3-dimensional finite…
A comparison of resin infiltration and microabrasion for postorthodontic white spot lesion
Introduction The objective of this research was to evaluate and compare the effectiveness of microabrasion and resin infiltration for white spot lesions (WSLs). Methods Patients with postorthodontic WSLs were enrolled…
Pharyngeal airway dimensional changes after orthodontic treatment with premolar extractions: A systematic review with meta-analysis
Introduction The objective of this research was to evaluate the effect of orthodontic extraction on the pharyngeal airway volume and Minimum cross-sectional area (MCA) in growing and adult patients. Methods…
Does maxillary yaw exist in patients with skeletal Class III facial asymmetry?
Introduction This study aimed to evaluate maxillary skeletal and dental yaw in patients with skeletal Class III facial asymmetry and investigate its correlation with menton deviation. Methods Initial cone-beam computed…
A comparative assessment of failures and periodontal health between 2 mandibular lingual retainers in orthodontic patients. A 2-year follow-up, single practice-based randomized trial
Introduction The objective of this study was to compare the survival rates and periodontal health in patients with 3-strand round twisted (RT) vs 8-strand rectangular braided (RB) fixed retainers bonded…
Occlusal stress distribution in the human skull with permanent maxillary first molar extraction: A 3-dimensional finite element study
Introduction The objective of this research was to analyze the effect of orthodontic treatment with maxillary permanent first molar extraction on the occlusal stress distribution and displacement in the human…
Maturation stages of the sutures in the median palatine evaluated with cone-beam computed tomography
Introduction This study aimed to evaluate the influence of age, sex, and facial growth patterns on the maturation stage of midpalatal sutures. Methods We selected 90 total skull cone-beam computed…
Mandibular premolar transplantation to replace missing maxillary anterior teeth: A multidisciplinary approach
One of the most challenging problems for orthodontists is that of multiple missing maxillary teeth in a growing patient. In many patients, a good treatment option is autotransplantation. This case…
Canine avulsion: An extreme complication of a fixed mandibular lingual retainer
The use of fixed retainers at the end of a course of orthodontic treatment has become standard practice. The main complication that can occur with fixed retainers is the detachment…
Missing participant outcome data in meta-analysis. Part I
Missing participant outcome data (MOD) are ubiquitous in clinical trials and may threaten the validity of the results. The risk of bias associated with MOD is carried over to the…
Is there a “write” way?
I know I’m gonna start some fights here, so let’s get to it. When you obtain a patient’s informed consent, does it have to be in writing? Apparently not in…
Effect of build angle and layer height on the accuracy of 3-dimensional printed dental models
Introduction Three-dimensional (3D) printing technologies are profoundly changing the landscape of orthodontics. To optimize treatment-oriented applications, dimensional fidelity is required for 3D-printed orthodontic models. This study aimed to evaluate the…
Geometric morphometric analysis of growth patterns among facial types
Introduction Extreme patterns of vertical facial divergence are of great importance to clinicians because of their association with dental malocclusion and functional problems of the orofacial complex. Understanding the growth…
