Ammonium-based methacrylate in an experimental dental adhesive
I read with great interest the article by Nascimento et al in the May 2017 issue on the effects of adding an ammonium-based methacrylate to an experimental dental adhesive for bonding…
Promoting ethical minds in orthodontics
Howard Gardner, author of the multiple intelligence theory, supports the idea that ethics is fundamental in order to do a “good work.” Someone with unethical behavior can have an intelligent…
Impacted and transposed canine
I appreciate the efforts of Lee et al, who wrote a fantastic case report on an impacted and transposed canine in the June 2017 issue. Treatment planning as well as execution…
Upper airway differences between Class II and Class III children
We read the article by Dr Tomonori Iwasaki et al (Iwasaki T, Sato H, Suga H, Takemoto Y, Inada E, Saitoh I, et al. Relationships among nasal resistance, adenoids, tonsils, and tongue…
Bisphenol A and orthodontics: An update of evidence-based measures to minimize exposure for the orthodontic team and patients
The purpose of this editorial is to present an update of the evidence on bisphenol A (BPA) in orthodontics by critically reviewing the available evidence, which often shows variable validity…
Miniscrew-assisted multidisciplinary orthodontic treatment with surgical mandibular advancement and genioplasty in a brachyfacial Class II patient with mandibular asymmetry
This article describes the complex dental treatment of a 43-year-old man with skeletal Class II, mandibular asymmetry, severe brachyfacial pattern, Class II Division 2, canting of the occlusal plane, and…
Long-term stability of Class II treatment with the Jasper jumper appliance
Introduction Treatment of Class II Division 1 malocclusion with orthopedic devices combined with fixed orthodontic appliances has shown excellent results when used in growing patients. We aimed to evaluate the…
Numeric simulation model for long-term orthodontic tooth movement with contact boundary conditions using the finite element method
Introduction Although many attempts have been made to simulate orthodontic tooth movement using the finite element method, most were limited to analyses of the initial displacement in the periodontal ligament…
Nonsurgical treatment of an adult with a skeletal Class II gummy smile using zygomatic temporary anchorage devices and improved superelastic nickel-titanium alloy wires
Patients with a severe gummy smile and a skeletal Class II profile are difficult to treat. This case report describes an effective treatment alternative for improving a gummy smile in…
In-vivo determination of critical force levels using an intraoral electromechanical device to measure nonpathologic tooth mobility
Introduction An electromechanical device was used to experimentally characterize the movement of a single tooth within the periodontal ligament space. The force magnitude leading to the complete compression of the…
Effects of low-level laser irradiation on the rate of orthodontic tooth movement and associated pain with self-ligating brackets
Introduction The aim of this study was to evaluate the effect of low-level laser irradiation applied at 3-week intervals on orthodontic tooth movement and pain associated with orthodontic tooth movement…
Survival analysis, part 3: Cox regression
Another approach to analyze survival data is to use regression analysis. This can be accomplished by applying Cox regression, which allows us to calculate a special form of rate ratios…
ENPP1and ESR1genotypes associated with subclassifications of craniofacial asymmetry and severity of temporomandibular disorders
Introduction We investigated whether ACTN3 , ENPP1 , ESR1 , PITX1 , and PITX2 genes which contribute to sagittal and vertical malocclusions also contribute to facial asymmetries and temporomandibular disorders…
Effect of temporomandibular joint articular disc repositioning on anterior open-bite malocclusion: An orthodontic-surgical approach
An anterior open bite is a challenge to orthodontic treatment; it has a multifactorial etiology and a wide range of intervention options. Temporomandibular joint (TMJ) disorders are a risk factor…
Protein and mRNA expressions of IL-6 and its key signaling factors under orthodontic forces in mice: An in-vivo study
Introduction The purpose of this study was to investigate the mechanical loading-induced changes in protein and mRNA expressions of interleukin-6 (IL-6) and its key signaling factors glycoprotein 130 (gp130), signal…
Strategies for improved interdisciplinary care and communication in orthodontics
Interdisciplinary care and communications with other doctors require meticulous management. It is frequently difficult to oversee a collaborating doctor’s work, thoughts, and risk management practices. Professionals from different disciplines often…
Possible alternative treatment for mandibular asymmetry by local unilateral IGF-1 injection into the mandibular condylar cavity: Experimental study in mice
Introduction The purpose of this study was to investigate whether a local unilateral IGF-1 injection into the mandibular condylar cavity can induce unilateral endochondral mandibular growth without any systemic adverse…
Adverse clinical events reported during Invisalign treatment: Analysis of the MAUDE database
Introduction The objectives of this study were to examine adverse clinical events after the use of the Invisalign system and to provide an overview of the actions taken by the…
