3. 3a-TADS- Closure of extraction space
• Between maxillary 1st molar and 2nd premolar buccally.
• Purpose: Retraction of the maxillary anterior teeth, Intrusion of maxillary buccal teeth
• Diameter: 1,2 mm and 1,3 mm, Length; 7-8 mm .
• The mesio-buccal root of the maxillary 1st molars are curved mesialy. to avoid root injury drill
the bone somewhat mesial to the contact point between the 2nd premolar and 1st molar .
Oussama SANDID - Mohamad ABOUALNASER- Awatef SHAAR

4. 3b-TADs- Retraction of anterior teeth
• Increased overjet and/or anterior crowding, Normal or increased overbite, Buccal mini-
implants (1.5mm diameter, 9mm length, short neck) inserted in U5-6 areas bilaterally.
• Powerarms (on a 19x25 steel archwire) to assist bodily incisor retraction and limit
intrusive effects on maxillary molars.

7. 3e-TAD's- Molar intrusion
• 2 mini-implants from the buccal and palatal sides on one tooth will exert intruding force
without tipping
• Dimension: Diameter 1,6mm Length 6-8 mm
Oussama SANDID - Mohamad ABOUALNASER- Awatef SHAAR

8. 3f-TAD's - Open Bite
• Anterior openbite with an increased mandibular plane angle.
• Anchorage and intrusion by TPA.
• Palatal mini-implants (1.5mm diameter, 9mm length, long neck) inserted U6-7s (or U5-6s if
U7s not fully erupted) , TPA d'intrusion rigide fabriqué avec 5mm de dégagement au milieu
du palais.

9. 3g-Maxillary tuberosity Area
Molar Distalization
• Purpose: Retraction of the maxillary posterior teeth
• Diameter: 1,3 -1,5 mm, Length 7-8 mm.
• Microimplants placed on the maxillary tuberosity area in lingual orthodontic treatment

10. • Purpose: Uprighting of tilted mandibular molar.
• Retraction of the mandibular teeth or the whole dentition
• Diameter: 1,3-1,6mm., lengh: 6-10 mm.
3h-Microimplamts in the Retromolar area

11. 3i-Miniscrew Applications in Orthodontics Mesialization
• Examples of miniscrew-supported mechanics for predictable unilateral space
closure. Miniscrews prevented the typical reactive side effect of midline shift or
anterior anchorage loss that would have occurred with traditional orthodontic
mechanics
