3Q5. More about TAD.

What is TAD made of?

Mini-Implant, just like regular dental implant, is made of biologically compatible medical grade Titanium or Titanium 6AL-4V(Titanium alloy containing 6% Aluminium and 4% Vanadium alloy). These material have tested and used throughout the world for last 20 to 30 years with minimal problems and side effects.


How is TAD placed?

Placement of TAD are fairly simple and is usually no less comfortable than normal dental procedures such as placing a dental restoration.

The steps for placement of mini-implant is as follows:

  1. Have patient rinse out their mouth with anti-microbial oral rinse.
  2. Application of topical and local anesthetic in the area of placement.
  3. Depending on the gingival tissue may or may not require use of small diameter tissue punch (d~1mm).
  4. Depending on technique and location – may or may not require preparation of the implant space.
  5. Placement of the mini-implant – usually by hand instrument.
  6. Immediate application of the implant or application after several week depending on the orthodontist.


After the local anesthetic wear away, patient may experience some discomfort for up to two or three days. For most patients, discomfort should be gone by next morning. While experiencing discomfort, patient should take over the counter pain medication such as ibuprophen or acetaminophen.


How is TAD taken out?


Removal of Mini-implant is even simpler than the placement. Mini-implant can usually be taken out with just the application of topical anesthetic. As soon as patient is numb, the implant is carefully removed with the hand instrument. The residual gum wound stops bleeding within few minutes and heal within few days. The jaw bone would heal within one to two months, and with no radiographic evidence of implant ever being in the bone within three months after removal.

What are the risks of using TAD?


The risks of using TAD are clearly delineated in the informed consent form of American Association of Orthodontists. Below, I have cut and pasted some of the risks mentioned in that informed consent.


Your treatment may include the use of a temporary anchorage device(s) (i.e. metal screw or plate attached to the bone.) There are specific risks associated with them. It is possible that the screw(s) could become loose which would require its/their removal and possibly relocation or replacement with a larger screw. The screw and related material may be accidentally swallowed. If the device cannot be stabilized for an adequate length of time, an alternate treatment plan may be necessary. It is possible that the tissue around the device could become inflamed or infected, or the soft tissue could grow over the device, which could also require its removal, surgical excision of the tissue and/or the use of antibiotics or antimicrobial rinses.

It is possible that the screws could break (i.e. upon insertion or removal.) If this occurs, the broken piece may be left in your mouth or may be surgically removed. This may require referral to another dental specialist.
 When inserting the device(s), it is possible to damage the root of a tooth, a nerve, or to perforate the maxillary sinus. Usually these problems are not significant; however, additional dental or medical treatment may be necessary.
Local anesthetic may be used when these devices are inserted or removed, which also has risks. Please advise the doctor placing the device if you have had any difficulties with dental anesthetics in the past.
If any of the complications mentioned above do occur, a referral may be necessary to your family dentist or another dental or medical specialist for further treatment.
