Dr. Sherry practices in Yukon, Oklahoma and is a graduate of the University of Oklahoma College of Dentistry. She practices cosmetic dentistry as well as orthodontics, and won the award for the best orthodontic case, at last summer’s annual Invisalign Meeting in Las Vegas. That case was also recently featured in the June issue of Inside Dentistry. She explains that, “My philosophy is that the least amount of dentistry is often the best. I would prefer to move teeth first then restore if necessary. Frequently, a very appealing esthetic result can be achieved through clear aligner therapy, alone.” [email protected] Pre- and post- treatment retracted smile. 4 the Journal: volume 01- issue 01 Pre- and post-treatment of the mandibular arch.

Final touches When the final upper aligner was delivered, we noted that a minor amount of rotation was still needed on the upper right lateral. To accomplish that, we placed a dimple, in the aligner, on the mesial-lingual of tooth #7, to apply rotation pressure to the tooth. This dimple functions much like a rotating wedge in conventional braces. the Academy for Clear Aligner Therapy 5 Upper Lateral Incisor Crossbite with Lower Premolar Case Reports in Lingual Version by Dr. David J. Harnick Introduction Introduced by Align Technology in 2008, Invisalign Teen is an excellent alternative to fixed appliances for some teenagers. Initially, Invisalign was primarily used to correct minor alignment, crowding, and spacing issues 1-4. However, as Clear Aligner Treatment (CAT) appliances gained acceptance this treatment modality was increasingly used to correct more complex malocclusions as well 5-9. Today, these techniques can be used predictably on teenagers. There are a number of teenagers that would prefer not to wear fixed appliances, for the obvious reasons. Since there is occlusal coverage during the entire treatment duration, Invisalign treatment presents new opportunities and challenges that need to be clearly understood. All types of malocclusions exist in these younger patients, including complicated skeletal disharmonies. Many of the patients are still growing. This case report of a Class 2 malocclusion demonstrates some important Figure 1: Initial montage photographs.
