Class II malocclusion treatment with a customized dual force distalizer
Intraoral distalizers associated with skeletal anchorage provide the major benefit of promoting molar distalization with minimum anchorage loss and patient cooperation. This case report presents the treatment of a 17-year-old…
Effect of print orientation on the dimensional accuracy of orthodontic aligners printed 3-dimensionally
Introduction Fabrication of orthodontic aligners directly via 3-dimensional (3D) printing presents the potential to increase the efficiency of aligner production relative to traditional workflows; however tunable aspects of the 3D-printing…
Mandibular condylar remodeling characteristics after simultaneous condylectomy and orthognathic surgery
Introduction The objectives of this study were to evaluate postsurgical condylar remodeling using a radiographical interpretation, quantify condylar volumetric asymmetry, and assess soft tissue symmetry after simultaneous unilateral high condylectomy…
Predictability of overbite control with the Invisalign appliance
Introduction Control of overbite is considered essential in achieving ideal orthodontic outcomes. Questions have been raised regarding the accuracy of ClinCheck software (Align Technology, Santa Clara, Calif) in predicting posttreatment outcomes…
Orthodontic treatment after intrusive dislocation and fracture of the maxillary central incisors
The treatment for intrusive dislocation is a clinical challenge and must be started soon after the intrusion injury. The affected tooth or teeth must be extruded by using light forces….
Occlusal changes in orthodontically treated subjects 40 years after treatment and comparison with untreated control subjects
Introduction The objective of this study was to compare the aging changes of the dental arches in orthodontically treated and untreated subjects after a 4-decade follow-up period. Methods This retrospective…
Comparison of 2 Invisalign tray generations using the Peer Assessment Rating index
Introduction This study aimed to establish if there is a significant difference in effectiveness between 2 generations of Invisalign trays in terms of Peer Assessment Rating (PAR) score reduction for…
Analysis of nasal airway symmetry and upper airway changes after rapid maxillary expansion
Introduction The objectives of this study were to assess the changes in right vs left nasal cavity volumes and minimum cross-sectional width, nasopharyngeal, and oropharyngeal volumes of the upper airway…
Comparison of enamel surface roughness and color alteration after bracket debonding and polishing with 2 systems: A split-mouth clinical trial
Introduction This split-mouth randomized clinical trial aimed to compare the enamel surface roughness (SR) and color alteration after bracket debonding and polishing using 2 systems. Methods After removal of excess…
Outcomes used in trials regarding the prevention and treatment of orthodontically induced white spot lesions: A scoping review
Introduction The objective was to identify and summarize the outcomes and evaluation methods used in clinical trials regarding the prevention and treatment of orthodontically induced white spot lesions (WSLs). Methods…
Why using a paired ttest to assess agreement is problematic?
In a study including cephalometric or dental model measurements, investigators often wish to examine the reliability of those measurements. Therefore, a percentage of the original measurements are repeated a few…
A randomized, 3-month, parallel-group clinical trial to compare the efficacy of electric 3-dimensional toothbrushes vs manual toothbrushes in maintaining oral health in patients with fixed orthodontic appliances
Introduction The aim of this single-blinded, parallel-group, randomized clinical trial was to compare the efficacy of electric 3-dimensional (3D) toothbrushes and manual toothbrushes in removing plaque and reducing gingival inflammation…
Correction of a gummy smile and lip protrusion by orthodontic retreatment with lingual appliances and temporary skeletal anchorage devices
A 28-year-old woman desired orthodontic retreatment for lip protrusion and excessive gingival display in both the anterior and posterior areas on full smiling. She had previously undergone an extraction orthodontic…
A surgery-first approach using single-jaw rotational mandibular setback in low-angle mandibular prognathism
For the treatment of low-angle mandibular prognathism, rotational mandibular setback surgery is usually performed with Le Fort I maxillary osteotomy to rotate the maxillomandibular complex simultaneously. However, this maxillary surgery…
Risky business
You are being sued for malpractice. The plaintiff said your treatment was negligent and caused significant injury. There is no claim for lack of informed consent. At trial, your defense…
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….
