Characteristics of miniscrews related to primary stability

The resistance to extraction of temporary anchorage devices (TADs) depends on various factors, including miniscrew design, shear strength, and bone density. This research introduces the thread shape factor (TSF) as a new factor for the evaluation of TAD mechanical properties. The authors evaluated three TADs for a total of 27 tests:...

DOSSIER SULLE CARATTERISTICHE DELLE MINISCREWS IN COMMERCIO

Recently, miniscrews have been planned and produced in order to strengthen anchorage during orthodontic treatment and to make patient's cooperation unnecessary; this is particularly important in adult patients, when it is not possible to use typical anchorage devices, such as extra-oral traction. In this article miniscrew types now available...

The aim was to evaluate impacted canines movement during traction, through superimposition of three-dimensional models acquired from Cone Beam CT (CBCT) before traction (T0) and three months after (T1), in order to highly precisely measure the movement of impacted canine.

Purpose: The aim of this study was to evaluate the outcome of a guided surgery protocol versus a conventional protocol. Materials and Methods: Twenty-six patients were randomly assigned to Guided Surgery or Conventional Surgery. In test group implants were placed in the maxilla using a tooth supported model-based surgical guide with a minimally...

The aim of this study is to evaluate the changes in sphenooccipital synchondrosis features 1-year after rapid maxillary expansion (RME) therapy, in order to assess the influence that these changes, if any, have on sagittal and vertical skeletal cephalometric variables. The results of this study indicated that RME had statically significant...
