281 P loss of the mandibular second premolars and first molars due to caries or periodontal disease can lead to mesioinclination of the second molars. Various orthodontic methods have been used to upright the lower molars for prosthetic rehabilitation,1-8 but these generally involve molar extrusion and reciprocal movement of the anchorage unit.9 Conventional flexible alloy or rectangular stainl...

(1) Background: Miniscrew insertion, using a surgical guide, aims to avoid possible adverse effects or complications. With the higher availability of both 3D imaging and printing, guides have been used more frequently in orthodontics. The aim present systematic review was find scientific clinical evidence concerning precision guided insertion miniscrews for temporary orthodontic anchorage. (2) ...

Corrosion of orthodontic miniscrews or temporary anchorage devices (TADs) has been proposed as a contributor to inflammation, which in turn is a factor in the clinical success of miniscrews. The purpose of this study was to measure the electrochemical properties of orthodontic miniscrews in artificial saliva with and without fluoride. The corrosion properties of three miniscrew products (Vector...

The aim of this study was to evaluate the effect of the direction and magnitude of the rotation moment to loaded orthodontic miniscrews on stability. In six adult male beagle dogs (12 months old), 36 orthodontic miniscrews were inserted into the mandibular buccal alveolar bone without drilling. Immediately after insertion, 24 miniscrews were loaded with 1- and 2-Ncm nickel titanium (NiTi) coil ...

OBJECTIVE To assess bone thickness for miniscrew placement in the mandible during mixed dentition by using digital volumetric tomograph (DVT). MATERIAL AND METHODS A total of 15 healthy patients aged 8-10 years old, with early exfoliated mandibular second deciduous molar, were included. DVT images of one quadrant of the mandible were obtained using Kodak extraoral imaging systems and analyzed...
