The history of orthodontic education: A century of development and debate
The history of orthodontic education in the United States spans more than 100 years. A number of exhortations have been repeated over the years by some of the best minds in…
Integration of 3-dimensional surgical and orthodontic technologies with orthognathic “surgery-first” approach in the management of unilateral condylar hyperplasia
Recent innovations in technology and techniques in both surgical and orthodontic fields can be integrated, especially when treating subjects with facial asymmetry. In this article, we present a treatment method…
Effectiveness and efficiency of a CAD/CAM orthodontic bracket system
Introduction The first straight-wire appliance was introduced over 40 years ago to increase the consistency and efficiency of orthodontic treatment. More recently, computer-aided design and computer-aided manufacturing (CAD/CAM) technology has been…
Class III malocclusion treated with distalization of the mandibular dentition with miniscrew anchorage: A 2-year follow-up
This case report describes the orthodontic camouflage treatment for a 16-year-old Chinese girl with a Class III malocclusion. The treatment included extractions of the mandibular second molars, fixed appliance therapy, and…
Short-term effects of strain produced on a split palatal screw-type hyrax appliance after rapid maxillary expansion: A clinical trial
Introduction The aim of this study was to establish an accumulated strain pattern in different parts of rapid maxillary expansion appliances and relate them to different vertical growth patterns. A…
Antibacterial orthodontic cement to combat biofilm and white spot lesions
Introduction White spot lesions are an undesired side effect of fixed orthodontic treatment. The objective of this research was to develop an antibacterial resin-modified glass ionomer cement (RMGIC) containing nanoparticles…
Selecting subjects with high craniofacial shape homogeneity for clinical trials
Introduction Morphologic homogeneity is desirable in sample selection of clinical studies that evaluate methods of treating craniofacial discrepancies in orthodontics. The purposes of this study were to assess sample selection…
Two-way analysis of variance: Part 1
In the previous article, I discussed 1-way analysis of variance (ANOVA) when we are interested in comparing the generated forces from 3 types of wires. In that example, we considered…
Biology of biomechanics: Finite element analysis of a statically determinate system to rotate the occlusal plane for correction of a skeletal Class III open-bite malocclusion
Introduction In the absence of adequate animal or in-vitro models, the biomechanics of human malocclusion must be studied indirectly. Finite element analysis (FEA) is emerging as a clinical technology to…
Bone remodeling during orthodontic tooth movement in rats with type 2 diabetes
Introduction Type 2 diabetes is known to affect bone metabolism. In this study, we aimed to determine the effects of type 2 diabetes on bone remodeling during orthodontic tooth movement….
