Short answer: An orthodontic mini-screw is a titanium screw a few millimetres long that is placed temporarily between the teeth or in the palate. It provides a stable anchorage point while teeth are being moved and is removed when treatment is finished. It is usually placed in a short procedure under local anaesthesia.
What does it do?
- Solid anchorage for moving teeth backwards or forwards
- Intruding over-erupted teeth and helping to correct an open bite
- Closing spaces in areas with missing teeth
- In some cases, it can be used instead of extraoral appliances such as headgear
How does it differ from a dental implant?
A dental implant is permanent and fuses with the bone; a tooth is built on top of it. A mini-screw is small and temporary and is easily removed at the end of treatment. For the relationship between implants and orthodontics, see our page on dental implants and orthodontics.
How is it placed?
- A suitable site is chosen by examination and X-rays.
- The area is numbed with local anaesthesia.
- The screw is placed in the bone with a special instrument; stitches are usually not needed.
- If needed, an elastic or spring is attached in the same session.
Care and points to note
- Gently clean around the screw with a soft brush.
- Do not wiggle the screw with your tongue or finger.
- If the screw loosens or there is swelling around it, let the clinic know.
Mini-screws can also be used together with clear aligner treatment. For the treatment process, take a look at our page on the clear aligner treatment process.
Frequently asked questions
Does having a mini-screw placed hurt?
The procedure is done under local anaesthesia; afterwards there may be mild tenderness for a day or two.
What happens if a mini-screw falls out?
Some screws can loosen; the orthodontist can place a new one in the same or a different site.
Does a mini-screw leave a mark after removal?
After removal, the small opening usually heals by itself within a few days.
Which appliance is right for you?
Which appliance is needed is decided after age, growth stage and the condition of the teeth and jaws have been assessed by examination and X-rays. At our clinic in Oran, Çankaya, Ankara, we discuss the options with you during the first orthodontic examination.
