I received the following e-mail from a general dentist who heard me lecture on interdisciplinary orthodontics. Dear Dr Kokich: I am hoping that you might provide me with some insight…
Local osteoprotegerin gene transfer inhibits relapse of orthodontic tooth movement
Introduction In orthodontic treatment, teeth can relapse after tooth movement without retention. The aim of this study was to evaluate the inhibition effects of local osteoprotegerin (OPG) gene transfer on…
Relapse of a maxillary median diastema: Closure and permanent retention
The purpose of this article was to describe the closure of a maxillary median diastema of a 26-year-old woman that had been corrected before during orthodontic treatment but reopened after…
Is traditional treatment a good option for an adult with a Class II deepbite malocclusion?
The Tweed-Merrifield directional force technique is a useful treatment approach for a patient with a Class II malocclusion with dentoalveolar protrusion. The purpose of this case report was to present…
One-phase vs 2-phase treatment for developing Class III malocclusion: A comparison of identical twins
Despite the known influence of early treatment on the facial appearance of growing patients with skeletal Class III malocclusion, few comparative reports on the long-term effects of different treatment regimens…
Digital live-tracking 3-dimensional minisensors for recording head orientation during image acquisition
Introduction Our objective was to test the value of minisensors for recording unrestrained head position with 6 degrees of freedom during 3-dimensional stereophotogrammetry. Methods Four 3-dimensional pictures (3dMD, Atlanta, Ga)…
Eagle’s syndrome in an orthodontic patient
This purpose of this article was to report the clinical case of a patient with Eagle’s syndrome. She was referred to the orthodontic clinic by her general clinician, with the…
Vertical alveolar growth in subjects with infraoccluded mandibular deciduous molars
Introduction Our objective was to compare vertical alveolar growth in areas adjacent to infraoccluded deciduous molars with growth in areas of deciduous molars and normal occlusion for a period of…
Analysis of stress in bone and microimplants during en-masse retraction of maxillary and mandibular anterior teeth with different insertion angulations: A 3-dimensional finite element analysis study
Introduction The proper angle of microimplant insertion is important for cortical anchorage, patient safety, and biomechanical control. However, the actual impact of different insertion angulations on stability is unknown. Methods…
Orthognathic treatment for a patient with facial asymmetry associated with unilateral scissors-bite and a collapsed mandibular arch
Subapical mandibular surgeries have been used to correct vertical malocclusion and interdental problems associated with mandibular deformity. Subapical surgery to the anterior part of the mandible is applicable in many…
Randomization. Part 3: Allocation concealment and randomization implementation
Randomization consists of 3 steps: generation of the random allocation sequence, allocation concealment, and implementation of the random allocation sequence. In the previous 2 articles, we discussed the methods to…
Long-term skeletal and dental stability of mandibular symphyseal distraction osteogenesis with a hybrid distractor
Introduction The purpose of this study was to examine the long-term skeletal and dental stability of mandibular symphyseal distraction osteogenesis (MSDO) with a tooth-borne and bone-borne hybrid distractor. To differentiate…
