Anchorage Screw - Orthodontic Mini Screw

#Orthognathic Surgery and #Orthodontic #Anchorage Screws (TADs)

Orthognathic anchorage screws, also known as temporary anchorage devices (#TADs) or orthodontic micro-implants, are widely used in orthodontics and oral-maxillofacial surgery to provide stable anchorage for tooth movement and skeletal corrections.

🪛 🔧 Functions and Applications:
① Enhancing Anchorage Stability
TADs serve as a fixed anchorage point, preventing unwanted tooth movement during orthodontic treatment.
Unlike traditional anchorage methods that rely on other teeth, TADs provide direct and stable support.

② Accelerating Tooth Movement
By applying force directly to the teeth, TADs reduce force dissipation and allow more efficient tooth movement, shortening treatment time.

③ Managing Complex Malocclusions
TADs are particularly useful in cases involving:
Space closure after tooth extraction (preventing mesial movement of molars).
Retraction of anterior teeth to correct protrusion (bimaxillary protrusion or "buck teeth").
Distalization of molars to correct Class II (overbite) or Class III (underbite) malocclusions.

④ Adjunct in Orthognathic Surgery
TADs assist in pre- and post-surgical stabilization for patients undergoing jaw surgery for skeletal discrepancies.

⑤ Replacing Traditional Extraoral Appliances
TADs eliminate the need for bulky headgear, improving patient comfort and compliance.

⑥Protecting Periodontal Health
By preventing unwanted tooth tipping or bone resorption, TADs help maintain periodontal integrity, especially in adult orthodontic patients.
