Alveolar corticotomies for accelerated orthodontics: A new mini-invasive technique
Publication date: Available online 8 July 2019Source: International OrthodonticsAuthor(s): Jean-Baptiste Charrier, Hugo AncelSummaryOrthodontic and surgical techniques are constantly evolving and practitioners are facing an increasing demand for shorter treatments, with an expectation of results equivalent to conventional treatments. Corticotomies have made it possible to partly meet this need by facilitating dental movement in adult orthodontic care. Many surgical corticotomy techniques were proposed in the past presenting advantages but also a certain number of disadvantages. After retracing the various surgical techniqu...

Effects of orthodontic appliances on the diagnostic capability of magnetic resonance imaging in the head and neck region: A systematic review
ConclusionsThere is fair evidence to suggest orthodontic appliances, mainly those with SS, cause MR artefacts. Removal of metal orthodontic appliances prior to MR scans is recommended, especially if the area of interest is near the orthodontic appliance. Additional evidence is needed to provide guidelines to clinicians.RésuméObjectifsLes patients qui suivent un traitement orthodontique fixe actif ou qui se trouvent en phase de contention fixe peuvent nécessiter une IRM (MR) de la région de la tête et du cou. Les orthodontistes ont la tâche difficile de décider si les appareils orthodontiques doivent être gardés ou...

The effect of miniscrew length and bone density on anchorage resistance: An in vitro study
ConclusionThe length of miniscrew and the density of bone affect the stability of miniscrew. In bone with optimum density, 10 mm and 8 mm miniscrew equipped good anchorage resistance while in bone with low-density only 10 mm miniscrew provided favourable anchorage resistance.RésuméIntroductionIl est en pratique difficile d’obtenir un ancrage absolu satisfaisant avec un ancrage conventionnel et cet obstacle pourrait être surmonté en utilisant des mini-vis. Le taux de réussite de l’utilisation d’une mini-vis dépend de sa stabilité qui a été déterminée par sa longueur, la densité osseuse, l’...
