First Smart Aligner with ActiveMemory™
Case Study
01
No TADs to Achieve Bilateral Intrusive Force
Patient Information
Male, adolescent
Permanent dentition
4D Aligner™
Treatment duration: 3 months
Treatment Story
The patient’s tooth #26 had supra-erupted, causing insufficient occlusal clearance for the crown restoration of tooth #36. The treatment plan involved opening clearance for the crown restoration by distalizing tooth #27 in two trays and intruding tooth #26 in one tray.
The aligners were designed with direct printed buttons and subgingival trimlines for elastics, which achieves bilateral intrusive force with no temporary anchorage devices (TADs).
After 3 trays in 3 months with no pain, patient was ready for his implant procedure.

02
Printed Smooth Bite Ramp to Correct Cross Bite
Patient Information
Male, adolescent
Permanent dentition
4D Aligner™
Treatment duration: 9 months
Treatment Story
The patient wanted to correct posterior crossbite. The treatment plan included upper 7s crossbite correction, buccal tipping of lower right to achieve symmetry with lower left quadrant, and lower anterior alignment.
The aligners were designed with no attachments, button cut-outs for elastics, multi-thickness and a smooth bite ramp.
After 9 months, posterior crossbite was corrected obviously.
The treatment is still in progress.

03
No Attachments to Expand Arch, Solid Tongue Spikes to Correct Tongue Habit
Patient Information
Female
Mixed dentition
4D Aligner™
Treatment duration: 2 months
Treatment Story
The patient had a bad tongue thrusting habit, leading to the anterior protrusion and a narrow arch. The treatment plan involved tongue habit correction by using togue spikes and expanding arch.
The aligners were designed with no attachments, multi-thickness and solid tongue spikes.
The patient was adapting well to 4D Aligner™ and tongue spikes. Initial improvements in expanding and tongue positioning are evident.
The treatment is still in progress.

04
No Attachment to Solve Lower Incisor Root Torque Issue
Patient Information
Female, adolescent
Permanent dentition
4D Aligner™
Treatment duration: 7 months
Treatment Story
The patient had a lower incisor positioned too far facially, with a Class I malocclusion and torque issue. The treatment plan was to use 4D Aligner™ to move the incisor root to a healthier position.
The aligners were designed with no attachments, multi-thickness. Additional thickness was applied at the neck of anterior teeth, with pressure on the gingival 1/3 buccal and incisal 1/3 lingual areas to correct the root.
After 7 months' treatment, the root torque issue was solved without using any attachments.

05
No Attachments to Correct Deep Bite and Achieve Premolar Rotation
Patient Information
Female, adolescent
Permanent dentition
4D Aligner™
Treatment duration: 12 months
Treatment Story
The patient had worn front teeth and was diagnosed as a Class II malocclusion with deep bite.
The treatment plan involved creating overjet and anterior open bite to prepare for restoration of worn dentition. The space in lower anterior was maintained to create reduced overjet.
The aligners were designed with no attachments and multi-thickness.
The patient responded well to the aligner treatment. Notably, despite the absence of attachments, the patient's upper first premolars showed significant rotation, and there was a marked improvement in the deep overbite.
The treatment is still in progress.
