02 · TADs devices

Bone-anchorage devices
tailored to your signature.

Custom-designed temporary anchorage devices (TADs) — distalization, mesialization, expansion, intrusion. Designed by orthodontists for accurate surgical placement and simple chairside activation.

02 · Why Sunday

Your TAD appliances,
engineered for precision.

An anchorage device's success rests on three pillars: a biomechanically validated insertion site, a geometry adapted to the desired movement, and an activation protocol simple to execute at the chair.

03 · Range

A device for every
clinical scenario.

Expand, mesialize, distalize, release an impacted canine, intrude a segment or guide infra-zygomatic insertion — we design the device tailored to your prescription.

Hybrid MARPE

Hybrid palatal expander

Hybrid palatal expander combining dental and bone anchorage via mini-screws. Custom insertion guide included.

MARPE hybride
Bone-borne MARPE

Bone-borne expander

Fully bone-borne palatal expander on two or four mini-screws. Ideal for adult patients. Insertion guide included.

Disjoncteur ostéo-porté
Mesial / Distal Slider

Mesial / distal slider

Molar mesialization or distalization device with skeletal anchorage on palatal mini-screws. Insertion guide included.

Mesial / Distal Slider
Canine traction

TADs canine traction

Impacted canine traction device with indirect TADs anchorage. Controlled, reproducible traction trajectory.

Traction canine sur minivis
Molar intrusion

Molar intrusion device

Palatal molar intrusion appliance on mini-screws. Indicated in open-bite correction via posterior intrusion.

Dispositif d'ingression molaire
Insertion guide

Insertion guide

Custom surgical guide for TADs insertion in the infra-zygomatic crest. Optimal precision and safety.

04 · Integrated auxiliaries

Integrated auxiliaries for
infinite applications.

Your appliances can carry custom auxiliaries, designed and integrated directly into the metallic framework during modeling. No separate bands or lab soldering required.

01

Tubes 0.022" or 0.018"

For vestibular or lingual archwire passage — direct multi-band integration into the framework, no lab soldering.

02

Aligner attachments

Retention arms or support surfaces compatible with all current aligner systems — thermoformed or direct-print.

03

Hooks

For intermaxillary or class elastics placement — clinical positioning defined on the scan.

04

Nance extension

Integrated Nance button to reinforce anterior anchorage when the clinical prescription requires it.

05 · Workflow

The TADs workflow.

Each device follows a secure workflow — 3D imaging, surgical validation, print-ready files — ensuring placement safety and predictability.

ÉTAPE 01

Case submission

Upload intra-oral scans, CBCT and prescription on Sunday Studio. The team analyzes the anatomy, possible insertion sites and biomechanical needs.

ÉTAPE 02

Device design

Our team designs the device and its insertion guide: geometry of the active piece, force vectors, TADs position validated on CBCT.

ÉTAPE 03

Print-ready files

Final delivery: STL files for the device and surgical guide, activation protocol and clinical instructions for chairside placement.

06 · Clinical support

Direct communication
with our orthodontists.

Surgical TADs placement is a precise gesture. We remain available to secure every step — from the choice of insertion site to clinical activation.

Dedicated Sunday messaging

A question, a doubt, an adjustment? We reply quickly — directly with the orthodontist following your case.
