Why do I need to have a mini-screw?

In an effort to flow poorly placed enamel, the opposite surrounding teeth commonly offer a solid guide for the force applied by means of the brace.

The principle issues which we can come upon when putting a micro-screw are:

Premature loosening of the micro-screw;An inflammatory reaction around the micro-screw with subsequent expulsion of the latter and the simultaneous lack of a small quantity of bone mass across the micro-screw;Micro-screw breakage;Periodontal damage when we “contact” the dental detail with the micro-screw;damage to anatomical systems near the insertion web site (vascular, neural and maxillary sinus); Decubitus ulcer at the alveolar mucosa and buccal mucosa, which often develops, above all, in the inferior dental arch.

These days, you could find osteointegrable micro-screws with a hard floor. After insertion of the screws, one ought to await osteointegration to occur before loading them. they are greater tough to do away with.


Micro-screws with a clean floor also exist, and those are basically used by orthodontists. these screws do no longer osteointegrate and that they come to be anchored to the bone via friction.


let us begin with the aid of recounting some thing that's handiest the fruit of our revel in. even as it's far actual that during implantology the conical-shaped screw lets in for a extra primary stability and consequently an accelerated fact of osteointegration, the equal can't be stated for easy, non-osteointegrable micro-screws. The clean micro-screw is anchored through the friction that it has with the bone.


If we use a conical micro-screw, it is able to grow to be completely unscrewed if grew to become just half of way anticlockwise. on the other hand, a cylindrical micro-screw maintains to rub alongside its path without dropping balance despite the fact that it turns into barely unscrewed. thus, judging from our revel in, the conical, non-osteointegrable screws need to now not be used.


Moreover, if elastic bands are used, it's miles critical to lock them to the pinnacle with a few composite fluid as a way to save you micro-screw loosening. this is because band oscillations, which may be produced when the affected person speaks or eats, are transmitted to the micro-screw thereby loosening it. Infact, an oscillation of the band transmits a pressure to the micro-screw in a clockwise direction, and moments later every other pressure in an anti-clockwise path. because the force inside the anti-clockwise direction is about in opposition to a lesser friction of the micro-screw, the screw has a tendency to loosen. in an effort to save you this from happening, it is sufficient to restoration the elastic band to the micro-screw the use of a few fluid composite which maintains it in region.
