Have you ever shared treatment of a patient with another colleague? For example, maybe you practice in an office that has several partners and associates, and all the doctors treat…
Placement angle effects on the success rate of orthodontic microimplants and other factors with cone-beam computed tomography
Introduction The purpose of this study was to evaluate the effect of placement angles on the success rate of orthodontic microimplants and other factors with cone-beam computed tomography images. Methods…
Cortical bone thickness of the alveolar process measured with cone-beam computed tomography in patients with different facial types
Introduction The purpose of this study was to determine the cortical bone thickness of the alveolar process in the maxilla and the mandible on cone-beam computed tomographs of adults with…
Factorial analysis of variables affecting bone stress adjacent to the orthodontic anchorage mini-implant with finite element analysis
Introduction Mini-implants are now widely accepted as anchorage for orthodontic tooth movement because of the convenience of the placement procedure, their comparative low cost, and the fact that they can…

Is there justice in generosity?
Your downtown practice is growing slowly but surely despite the stagnated economy. One consistent referral source has been a large manufacturing plant, many of whose employees and families you have…
Author’s response
It is gratifying to know that others are carefully reading the orthodontic literature, especially when it is one of your own articles. Dr Cao is correct in noting that the…
Cortical bone thickness for miniscrew placement in adults
We read with great interest the article that documents cortical bone and ridge thickness (Horner KA, Behrents RG, Kim KB, Buschang PH. Cortical bone and ridge thickness of hyperdivergent and…
Statistical treatment of the sample
With interest, we read the article entitled “How does orthodontic treatment affect young adults’ oral health-related quality of life?” by Palomares et al in the June 2012 issue of the AJO-DO…
It’s worse than we thought!
The current AAO Consumer Awareness Program is targeting adults over the age of 30 years. It is hoped that this new initiative will make adult consumers more aware of the…
Authors’ response
We were very pleased by the interest of Drs Wang, Yi, and Bai in our article. We have carefully read their letter. We are grateful for the opportunity to offer…
Application of a new viscoelastic finite element method model and analysis of miniscrew-supported hybrid hyrax treatment
Introduction In this study, we aimed to assess the ability of a new viscoelastic finite element method model to accurately simulate rapid palatal expansion with a miniscrew-supported hybrid hyrax appliance….
Combining traditional techniques to correct anterior open bite and posterior crossbite
The treatment of anterior open bite often requires the use of skeletal anchorage to prevent excessive eruption of the posterior teeth and consequent downward rotation of the mandible. However, this…
Correction of bilateral impacted mandibular canines with a lip bumper for anchorage reinforcement
Multiple treatment options are available to patients with impacted manibular canines in addition to a retained deciduous canine. This article describes the treatment of a prepubertal girl, aged 10 years…
Orthodontic treatment of a patient with dentin dysplasia type I
Dentin dysplasia is a genetic disorder of the teeth that affects the dentin and the pulp. Type I is sometimes called “rootless teeth,” because of the loss of organization of…
Bilateral craniofacial microsomia: Orthognathic treatment for an advanced dentofacial deformity
In this article, we report the combined surgical and orthodontic treatment for a patient with bilateral craniofacial microsomia and facial asymmetry. The patient, a 24-year-old woman, sought treatment with a…
Effect of surgical exposure technique, age, and grade of impaction on ankylosis of an impacted canine, and the effect of rapid palatal expansion on eruption: A prospective clinical study
Introduction This study had 2 aims: (1) to assess whether the surgical exposure technique, the patient’s age, and the grade of impaction are associated with ankylosis of the impacted canine;…
Factors affecting the accuracy of buccal alveolar bone height measurements from cone-beam computed tomography images
Introduction The reasons for inaccuracies in alveolar bone measurement from cone-beam computed tomography (CBCT) images might be multifactorial. In this study, we investigated the impact of software, the presence or…
Multiplicity 1: Subgroup analyses
In orthodontics, as well as other fields, the simplest trial would involve a single outcome measure with a comparison of 2 treatments and no subgroup analyses. However, this is not…
