Australasian Dentist November-December 2018

Category AustrAlAsiAn Dentist 51 at CCC smiles in sydney showed an increased compliance with clear aligner wear even though our patients spent 2-5 minutes extra each week using the DM app compared to patients that were not using DM. We found that using DM can help reduce case revisions and attain more predictable outcomes even for complex movements with clear aligners. How can a smart-phone based app deliver such value? the answer lies in understanding the Hawthorne effect 17 . it is well known that the Hawthorne effect is a type of reactivity in which individuals modify an aspect of their behaviour in response to their awareness of being observed. so regular observations means patients are more likely to comply. Another mechanism by which DM is invaluable for clear aligner treatments is by personalising the customised orthodontic treatment plan for individual patients. speed of tooth movement is a function of underlying osteoclastic activity and mediated via numerous cytokines. since this is highly variable across individuals, DM and its developed Ai can help modulate and provide the appropriate aligner change schedule for the patient based on their compliance, underlying osteoclastic activity and stage of treatment. the good news is that the Ai-based DM app can be fully automated or semi-automated as per practitioner preferences. so you can drive it or discard it as you wish. lastly, DM acts as an active reminder system for practitioners and patients, increasing compliance with appliance wear and oral hygiene instructions. it is known active reminders have a positive effect on oral hygiene and adherence to appointments in orthodontic patients, in the short- and long-term 18 . Clear aligner treatments are no longer considered an alternative to traditional fixed appliances. in fact it is my 1st choice of treatment for many patients, from childhood to adulthood. strong evidence is lacking to fully understand its benefits for the patients that include freedom of diet, reduced chances of white spot lesions and increased motivation during treatment. similarly, practitioner benefits such as increased communication with patients, less disputes and reduction of unnecessary chairside time also need to researched in the future. Good luck and i hope the readers enjoy moving teeth predictably and efficiently using clear aligners! u lInICal Dr Katyal is an avid lecturer at national and international orthodontics conferences.
