Models for aligners
Full-arch orthodontic model play an integral role in clear aligner therapy. Sequential models can be printed and used to thermoform clear aligners. In addition, complete orthodontic model can be used in conjunction with spray separators and laser soldering to fabricate orthodontic appliances.
One Of the complicated cases to treat with Aligners is Distalization. Here, we planned sequential Distalization with posterior teeth to achieve Predictable results/outcomes. We planned Multiplanner Jumbo G6 /OAA(Optimized Anchorage attachments) which is proved to be a success to treat such retraction Cases. Considering the amount of Deepbite, we planned Bite ramps to facilitate Lower incisors intrusions. These bite ramps are repositioned in 2-stage considering the occlusal relationships of anterior teeth.
As Aligners apply “Push-type” forces, Rotation and Extrusion forces are considered a difficult movement to treat. Hence, Open-Bite Corrections are considered a difficult condition to treat with Aligners. Attachments are playing an important role In this case. Extrusion attachments are planned on Central Incisors (as small as 2 mm- same as Align’s optimized extrusion attachment). With Lateral, we use Dr. Jonathan Nicozisis’s “sash” attachment, which are multi planner beveled attachments designed to aid with rotation as well as Extrusion correction by fully engaging the maximum tooth surface of these small-sized teeth which usually gets slipped off and failed to track the movements. we planned HBA (Horizontal Bevelled Attachments) on Molars to aid in retentions.
The Treating clinician was willing to treat only social 6 teeth correction. The overjet reduction is planned with a Interproximal Stripping /IPR. Multiplanar SASH attachments are planned over upper laterals to aid in extrusion and rotation corrections. Also, palatal attachments planned on Upper incisors to facilitate palatal root Torque/Labial Crown Torque corrections. This palatal attachments will also serve as an bite ramps for deep bite correction.
Patient data such as photos and 3D scans are shared with AlignerConcierge along with filling an online treatment form.
Specialist Aligner Orthodontists develop Aligner treatment plans leveraging their knowledge of Aligner Mechanics gained by treating multiple patients. A url of the proposed treatment plan will be shared on email and can be modified if required by the customer.
Sequential 3D staging files can be printed using a 3D printer in office or by a third-party provider. These staging models than act as templates for thermoforming the Orthodontic Aligners.
Aligners can be fabricated by thermoforming a BPA-free plastic over the staging templates. We recommend to store the printed templates as patients might damage or lose their Aligners.
