22 Aside from aesthetic advantages, there is data to suggest the improvement of periodontal tissues during this type of treatment. 23, 24 This makes sense due to the very nature of the system and the patient’s ability to remove the appliance for optimal daily plaque biofilm removal. 25 Often resin buttons are added to facial surfaces of teeth, to assist in tooth movement; resulting in the need for the dental hygienist to be aware of their location to evaluate plaque control as well as to not remove those during scaling. This technology has given rise to some controversy over the clinical research, as many of the published papers are case reports. Concerns over final outcomes to correct malocclusion and potential higher relapse with Invisalign have also been reported. 26, 27 In addition, because of the ease of removal, patient compliance with aligners must be carefully monitored. As with any system that relies upon the patient, non-compliance is an issue and can delay treatment. 26 Other commercially available aligner systems include NuBrace () and the Red,White & Blue system () recommended for replacement of certain retainer devices.This technology has confirmed that adult patients are not only interested, but also willing to pursue orthodontic treatment, especially if it is aesthetically pleasing. What is wrong with conventional ligation? 81 • Failure to provide and to maintain full archwire engagement • High friction • Elastic ligation loses its elastisity over time (and therefore tooth con- trol) and they are sometimes lost • Potential impediment to oral hygiene Wire ligation is very slow Invisalign ® Before Invisalign ® After – 9 months treatment time/19 aligner sets Invisalign ® Aligner Placement Photo courtesy of Dr. R.

CDHA Journal Vol. 23 No. 2 11 LifeLongLearning Bio-Adaptive Therapy While fixed appliances have been readily available for decades, the use of appliances with lighter forces that work in natural harmony with the body – or bio-adaptive therapy – is growing in popularity. It has been well understood and accepted that light forces will effectively and quickly move teeth. 28 The challenge has been to develop a fixed appliance that will allow light force action with minimal friction and moderate force as seen when archwires are ligated to fixed appliances. The premise of bio-adaptive therapy, as defined and facilitated through the Damon ® System of brackets, archwires and treatment philosophy from Ormco Corp. (Orange, CA), takes into account this opportunity to achieve ideal tooth position and facial harmony while keeping vascular integrity of the alveolar cortical plate. “Optimum force levels for orthodontic tooth movements should be just high enough to stimulate cellular activity without completely occluding blood vessels in the periodontal ligament”.
