A basic rule of physics applies in orthodontics: to move a tooth, force is applied to it; however, the same force also acts in the opposite direction on the teeth from which support is taken. Preventing this unwanted side movement is one of the oldest problems of orthodontics. Orthodontic mini-screw applications provide a solution to this problem by creating a fixed support point. As DijiDent Oral and Dental Health Polyclinic, in Türkiye we consider this approach in suitable cases.
What Is Anchorage?
Anchorage means “support” in orthodontics. For example, in a plan to move the front teeth backwards, support is taken from the back teeth; however, during this, the back teeth also tend to move forward. As a result, the targeted amount of backward movement may not be achieved.
Traditionally, this problem was addressed with extraoral appliances or intraoral support systems. Some of these methods depend on patient compliance, and because of their visibility, problems with use are experienced, especially in adolescents.
How Do Mini-Screws Work?
Mini-screws are small, temporary support elements placed in the jawbone. By holding onto the bone, they create a fixed reference point. The force applied from this point moves only the targeted teeth; unwanted displacement of other teeth is prevented.
They are different from dental implants: they are not expected to fuse with the bone, they hold only mechanically and they are removed when their task is complete.
In Which Situations Are They Used?
- Moving the front teeth backwards: Controlled positioning of protruding teeth.
- Moving elongated teeth back: Teeth that have come out of their sockets because their counterpart is missing.
- In gummy smile cases: In situations resulting from the vertical position of the front teeth.
- Moving the back teeth backwards: Gaining space for a non-extraction plan.
- Asymmetric corrections: When one-sided movement is needed in midline deviations.
- In cases with missing teeth: In situations where there are not enough abutment teeth.
Contribution to Non-Extraction Treatment
In some cases, space can be gained by moving the back teeth backwards with mini-screw support, and the need for extraction may disappear. This is an important advantage; however, it is not applicable in every case. The amount of space needed, the bone structure and the current inclination of the teeth are decisive.
How Is It Applied?
The procedure is done under local anesthesia and usually takes a short time. Most patients state that the procedure was simpler than they expected; it is an application that does not require stitches. Afterwards, there may be mild sensitivity in the area for a few days.
The placement position is planned in advance; a radiological evaluation is done so as not to damage the tooth roots. Three-dimensional imaging helps evaluate the spaces between the roots and the bone thickness.
Care
Cleaning the gums around the mini-screw is important. If plaque accumulates in the area, inflammation may develop and the hold of the screw may weaken. Gentle cleaning with a soft brush and following the additional applications your dentist recommends are necessary. If you notice redness, swelling or pain in the area, report it.
How Long Does It Stay?
Mini-screws are temporary. They are removed when the planned movement is complete; this is usually a short procedure that does not even require anesthesia. The small remaining area heals on its own.
Comparison with Extraoral Appliances
Extraoral appliances used for similar purposes in the past require wearing for a certain time each day and are visible from the outside. For this reason, use may not be regular, especially in adolescent patients, and treatment may deviate from the plan. Mini-screws, on the other hand, are constantly on duty and do not depend on patient compliance. This is an important difference that increases the predictability of the plan.
Risks and Limits
As with every application, there are limits here too. The screw may loosen or fall out early; in this case, re-placement is considered. The application may not be suitable in areas where bone thickness is insufficient. These possibilities are shared in the treatment plan from the start.
