Patented concave support collar (United States Patent # 7.806,686,B2) increases the anchorage loading capacity up to 50% and dramatically improves outcomes.

Anatomical design eases installation and improves results.
  • The Infrazygomatic standoff eliminates tissue interference with the ligature
  • The self-seating palatal washer speed installation, and provides standoff for ligature clearance
  • Narrow incisal anchor allows installation in critical areas avoiding root damage
  • Mesial anchors provide washer support for maximum strength
  • Dual thread sizes for maximum holding in the cortical bone
  • Easy self-tapping small diameter
  • Maximum holding power from the larger diameter cortical bone portion
  • Cannulated driver for safety and easy removal
  • Never again will the Orthodontist be concerned with unseating the anchor during driver removal
  • Foolproof safety using the attached ligature prevents dropping an anchor and potential swallowing by the patient.
  • Best practices avoid possible litigation
  • Proven Instrumentation
  • Hand drill for dense bone applications is quick, safe, and easy to use
  • Bits for the handset where necessary
  • Small removal wrench with good tactile feel
  • Cannulated driver
  • Convenient tray for system sterilization
  • Training and support developed and monitored by Dr. Fisher
  • Doctors only web site for system users included with the system
  • Hands on training seminars by Dr. Fisher and Associates for new users and C.E.
  • Doctors only web bulletin board and Q&A page and forums
  • Discrete communication Q&A with Dr. fisher through e-mail

  • Force Differential between TAAD without and TAAD with a base

    The purpose of this computation is to compare the force values placed on the bone at the point the anchor has the most force against bone of two TAADS that have the same force, same thread diameter, same head diameter , and the same height from force application to bone contact. The only different variable is the fact that the 2nd anchorís base of the head of the TAAD is placed on the cortical bone.

    This computation will show the force applied to the bone is less on the TAAD that has itís base against the surface of bone.

    The formula used is as follows: F1 X D1 = F2 X D2

    F1 = 200 grams
    F2 = the unknown
    D1 = 3mm
    D2 = 1mm for the TAAD without the base in contact with the bone.
             1.5 mm for the TAAD with base to bone contact.

    Anchor without Base Contact   Anchor with Base Contact
    200g x 3mm = F2 x 1mm 200g x 3mm = F2 x 1.5mm
    600g/mm = F2(1mm) 600g/mm = F2 x 1.5mm
    600/1 = F2 600g/1.5 = F2
    F2 = 600 g/mm F2 = 400 g/mm

    The anchor with base contact has 200grams less force placed on the bone than the anchor without base contact. This will decrease the TAAD failure rate.
