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…
Agreement between mothers and children with malocclusion in rating children’s oral health-related quality of life
Introduction The aim of this study was to compare the assessment of oral health-related quality of life (OH-QoL) between children with malocclusion and their mothers, by using responses to the…
Comparative analysis of traditional radiographs and cone-beam computed tomography volumetric images in the diagnosis and treatment planning of maxillary impacted canines
Introduction In this prospective study, we compared differences in the diagnosis and treatment planning of impacted maxillary canines between 2 imaging modalities. Methods Twenty-five consecutive impacted maxillary canines were identified…
In-vitro orthodontic bond strength testing: A systematic review and meta-analysis
Introduction The aims of this study were to systematically review the available literature regarding in-vitro orthodontic shear bond strength testing and to analyze the influence of test conditions on bond…
Intraexaminer and interexaminer reliabilities of landmark identification on digitized lateral cephalograms and formatted 3-dimensional cone-beam computerized tomography images
Introduction The purposes of this study were to determine and compare the intraexaminer and interexaminer reliabilities of commonly used cephalometric landmarks identified on digitized lateral cephalograms and formatted cone-beam computerized…
Editor’s Comment and Q&A
Introduction The placement and removal torques of mini-implants were evaluated as an index of implant stability. We examined factors affecting the initial and long-term stability of mini-implants. Methods We measured…
