Bone stress and strain after use of a miniplate for molar protraction and uprighting: A 3-dimensional finite element analysis
Introduction The aim of this study was to use the finite element method to evaluate the distribution of stresses and strains on the local bone tissue adjacent to the miniplate…
Interdisciplinary treatment for an adult with a unilateral cleft lip and palate
A young man, age 18 years 4 months, with a concave profile, a skeletal maxillary deficiency, and a severe alveolar cleft with an unesthetic appearance of the maxillary anterior teeth was referred…
Biomechanical effectiveness of cortical bone thickness on orthodontic microimplant stability: An evaluation based on the load share between cortical and cancellous bone
Introduction The aim of this study was to determine the appropriate range of cortical bone thickness (CBT) for supporting an orthodontic microimplant. Methods Analysis of an orthodontic microimplant subjected to…
Case-control studies: Part 1
In a case-control study, a group of subjects from a specified study population who have the outcome of interest (the cases)—eg, patients with temporomandibular joint (TMJ) pain—is identified, and a…
Effect of bracket slot and archwire dimensions on anterior tooth movement during space closure in sliding mechanics: A 3-dimensional finite element study
Introduction It has been found that controlled movement of the anterior teeth can be obtained by attaching a certain length of power arm onto an archwire in sliding mechanics. However,…
Disparaging disparagement
Many of us worry about how to handle disparaging comments or posts made by disgruntled patients about us or our office on the Internet. Although there are many ways to…
Interlot variations of transition temperature range and force delivery in copper-nickel-titanium orthodontic wires
Introduction The manufacturing process for copper-nickel-titanium archwires is technique sensitive. The primary aim of this investigation was to examine the interlot consistency of the mechanical properties of copper-nickel-titanium wires from…
Efficacy of a fluoride-releasing orthodontic primer in reducing demineralization around brackets: An in-vivo study
Introduction A new, highly filled primer is currently marketed as a fluoride delivery system effective in reducing white spot lesions in orthodontic patients. However, no studies in the literature support…
Mandibular posterior anatomic limit for molar distalization
Introduction The purpose of this study was to investigate the mandibular posterior anatomic limit for molar distalization. Methods Three-dimensional computed tomography scans were obtained on 34 adults with a skeletal…
