Managing Complex Cases in Orthodontics. Kleber Meireles and Andre Machado Join me for a summary of a dynamic conversation between Kleber and Andre, It was a lecture full of biomechanics and the podcast will focus on specific examples with fixed appliances and aligners. Fixed appliance mechanics 1. Canine retraction in extraction case with buccal canine: sectional mechanics o Conventional sliding mechanics retract canine but also distally tip and rotate distal in o Loop mechanics § Mechanics = canine retraction – line of force buccal § Side effects = no distal in rotation due to line of the force buccal § Mechanics = sectional mechanics allows counter moment to increase as canine retracts = bodily retraction § Side effect = no distal tipping of the canine 2. Retraction of upper anterior teeth in extraction cases o Loss of anterior torque on retraction, o Torque mechanics: § Stop active space closure § Apply anterior buccal crown torque § When recovered, continue final space closure Aligner biomechanics Comment:  Physics is physics &amp; there is nothing magical appliance Distalisation with aligners · Not effective with aligners · Mechanics: Distal tip · Side effects: No root movement Solution · Attachments for molar distalisation: o 6mm:  horizontal requires 120g, 10mm from the CoR = 1200gm force required for counter moment, however no aligner material can deliver this force or provide retention to the force, therefore not effective tooth movement o 4mm attachment requires greater force, 1200/4 = 300g Issues with aligners · Rely more on companies to do the treatment planning o AI does not have knowledge of the roots and its angulation – which is difficult to correct even with conventional braces · Lack of stiffness in the aligners make it difficult to apply counter moment o For example incisor retraction in extraction cases Thank you to our sponsors for supporting this episode I hope to see you Porto for the Simply Ortho congress on the 9-11 of June

Managing Complex Cases in Orthodontics. Kleber Meireles and Andre Machado

In this episode, Cleveland Clinic neurosurgeon and researcher Andre Machado, MD, PhD, talks about deep brain stimulation and its potential to help stroke patients recover. Introduced in the 1990s, deep brain stimulation has been described as a pacemaker for the brain and has been used to treat a variety of disorders. Recently, Dr. Machado became the first to implant a deep brain stimulator in a stroke patient with paralysis. The Clinic will evaluate whether the brain stimulation, along with physical therapy, helps the patient regain movement.
