Chapter 1 provides a historical review of extraction therapy in orthodontics before describing the evolution of the coordinated arch development technique of nonextraction treatment. The coordinated arch development technique is…
The introductory chapter discusses the increasing awareness and need for orthodontic treatment among all age groups and the desirability of inconspicuous tooth alignment with an occlusion correction system that meets…
Introduction Although attractiveness and acceptability of orthodontic appliances have been rated by adults for themselves and for adolescents, children and adolescents have not provided any substantial data. The objective of this…
Introduction This study was conducted to determine whether variations in the morphology, size, or shade of maxillary canines would influence perceptions of smile attractiveness in patients with canines substituted for…
I got this e-mail the other day, and it prompted this article. Larry: Is malpractice dependent upon on a bad outcome, or is it a free-standing bad act? In discussing…
Introduction Mice with brachymorphism (bm) have defective chondrogenesis, including abnormal growth of the spheno-occipital synchondrosis. Malocclusion (anterior transverse crossbite) sometimes spontaneously occurs in inbred BALB/c- bm/bm mice, before the mandibular…
Introduction Our aim was to evaluate the effects of staining solutions on the discoloration of orthodontic adhesives. Methods Six orthodontic adhesives were investigated (Transbond XT [3M Unitek, Monrovia, Calif, USA],…
Introduction Our purpose was to study the mechanical properties and phase transformations of orthodontic wires submitted to in-vivo exposure in the mouth for different periods of time. Methods Stainless steel…
Introduction Mice with brachymorphism (bm) have defective chondrogenesis, including abnormal growth of the spheno-occipital synchondrosis. Malocclusion (anterior transverse crossbite) sometimes spontaneously occurs in inbred BALB/c- bm/bm mice, before the mandibular…
Introduction The purpose of the study was to examine the changes in stability of pharyngeal airway space (PAS) and hyoid bone position after 2 types of mandibular osteotomies in comparison…
Introduction In this study, we assessed the effects of age and sex on quality-of-life recovery after third-molar surgery. Methods Healthy subjects scheduled for removal of third molars were recruited at…
Introduction One common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. Bio-available minerals…
Introduction This study was conducted to determine whether variations in the morphology, size, or shade of maxillary canines would influence perceptions of smile attractiveness in patients with canines substituted for…
To prevent development of white spot lesions, orthodontists should assess each patient’s risk factors before and during treatment. Oral hygiene instruction is important, but patients might need to be assisted…
Introduction In this study, we assessed the effects of age and sex on quality-of-life recovery after third-molar surgery. Methods Healthy subjects scheduled for removal of third molars were recruited at…
Introduction En-masse sliding mechanics have been typically used for space closure. Because of friction created at the bracket-wire interface, the force system during tooth movement has not been clarified. Methods…
Introduction Although attractiveness and acceptability of orthodontic appliances have been rated by adults for themselves and for adolescents, children and adolescents have not provided any substantial data. The objective of…
