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…
