Shear bond strength of orthodontic brackets bonded to various esthetic pontic materials
Introduction In this in-vitro study, we compared the shear bond strengths of orthodontic brackets bonded to various commonly used esthetic pontic materials. Methods Prefabricated denture teeth (acrylic resin, Trubyte, Dentsply,…
Palatal configuration in Class II Division 1 malocclusion: A longitudinal study
Introduction The purpose of this study was to evaluate palatal contours in nonextraction orthodontic treatment and long-term stability in patients with Class II Division 1 malocclusions. Methods Data were obtained…
Mechanical behavior and clinical application of nickel-titanium closed-coil springs under different stress levels and mechanical loading cycles
Introduction The main advantage of superelastic nickel-titanium (NiTi) products is their unique characteristic of force plateaus, which allow for clinically precise control of the force. The aims of this study…
Optimum conditions for parallel translation of maxillary anterior teeth under retraction force determined with the finite element method
Introduction In this study, we used the finite element method to examine the optimum conditions for parallel translation of the anterior teeth under a retraction force. Methods Finite element models…
Effective en-masse retraction design with orthodontic mini-implant anchorage: A finite element analysis
Introduction The strategic design of an appliance for correcting a bialveolar protrusion by using orthodontic mini-implant anchorage and sliding mechanics must take into account the position and height of the…
Effect of saliva contamination on bracket failure with a self-etching primer: A prospective controlled clinical trial
Introduction The aim of this study was to evaluate in vivo the effect of saliva contamination at different stages of the bonding procedure on the bond failure rate and the…
Motivational factors and future life plans of orthodontic residents in the United States
Introduction The purposes of this study were to investigate factors influencing career choice and identify future life plans of orthodontic residents in the United States. Methods Program chairs and directors…
In-vitro study of cellular viability and nitric oxide production by J774 macrophages stimulated by interferon gamma with ceramic, polycarbonate, and polyoxymethylene brackets
Introduction Ceramic brackets are chemically inert in the oral cavity, whereas polycarbonate and polyoxymethylene brackets can degrade and release bisphenol-A and formaldehyde, respectively. More reliable tests are needed to assess…
Noncompliance maxillary molar distalization with the First Class Appliance: A randomized controlled trial
Introduction The aim of this study was to evaluate the treatment effects of the First Class Appliance (FCA) (Leone, Firenze, Italy) used for the distalization of maxillary first molars in…
