Clear aligners are evolving… but is the evidence keeping up?
Clear aligner therapy has expanded well beyond mild malocclusions, but is the evidence base keeping pace? A new narrative review brings together current research on aligner biomechanics, treatment efficiency, extraction mechanics and biological safety, offering clinicians a balanced view of where the evidence is strong and where it still falls short.
July 2026 Update
This month’s update looks at how continuous improvement shapes postgraduate dental education at LDI, from new practical videos and refreshed course content to ways you can get involved with your professional development this summer.
Does i-PRF actually reduce treatment time?
A randomised controlled trial in The Angle Orthodontist reinforces that whilst injectable platelet-rich fibrin (i-PRF) may show promise in accelerating isolated stages of tooth movement, the evidence does not support its routine use for reducing overall orthodontic treatment duration, nor did it significantly affect root resorption compared to standard fixed appliance therapy alone.
Can orthodontists really influence airway health?
An updated white paper in the American Journal of Orthodontics and Dentofacial Orthopaedics reinforces that whilst orthodontists are well-placed to screen for signs of sleep-disordered breathing during routine assessment, the evidence does not support a causal link between orthodontic extractions and airway dysfunction, nor should CBCT imaging be used in isolation to diagnose the condition.
May 2026 Update
The London Dental Institute welcomed its newest cohort across all three Diploma programmes on 29th May, whilst continuing to expand its Virtual Learning Environment with new webinars, revised teaching materials, and updated course content throughout the month.
Can Monitoring Increase Patient Compliance in Aligner Therapy?
Patients undergoing clear aligner therapy who were aware their wear time was being monitored logged notably higher daily usage than those who were not, though neither group reached the recommended 20 to 22 hours per day.
April 2026 Update
April carried a distinct sense of momentum at the London Dental Institute, shaped by a sold-out CUSP workshop, growing anticipation for October’s Orthodontic Conference, and the steady preparation of clinicians stepping into the upcoming May Diploma cohort.
Do Invisalign Aligners Really Need 22 Hours of Wear Per Day?
Consistency drives results. Reduced aligner wear may work for mild upper crowding, but full-time use remains the most reliable choice, especially for lower teeth.
Do Dentists Really Have Time for Postgraduate Study?
Finding time for postgraduate study in dentistry is less about having free hours and more about consistently using small, practical moments throughout the week to make steady progress.
5 Things You Can Expect From Postgraduate Dental Exams
Postgraduate dental exams today are structured around real clinical thinking, offering flexible online assessments and case presentations that help practising dentists consolidate knowledge and translate learning into confident patient care.
