Dental intrusion with microscrews

Abstract

The dental intrusion has been always a challenge thoughout the history of the orthodontic treatments. The difficulty in finding an anchorage point on which it could be set controlled intrusive forces onto the dental peces by means of elastic elements has taken to the orthodontists to look for varios possibilities with not the same success.

The extraoral anchorage elements usted till then were limited, in many opportunities, by the disconfort they produced in the patient or by their lack of colaboration when the treatment requiered it. In the intraoral treatment it did not guarantee the lack of parasite movements in other teeth and sometimes the intrusion Washington limited when the desired movement was of a great sale.

The microscrews have opened the doors of a new universe of possibilities in the dental intrusion thanks to its versatility. The incorporation of an element which exceed the anchorage of every intraoral element used till now, which has the capacity of being used without generating the parasite effect, that has the ability of being placed in a simple way in almost every place in the mouth where exists bone below, allows open in a significative way the our possibilities in the success in our treatments. This, in addition to its reduced size improves the experience of the patient, generating a mayor approval to the treatment and compromise with it.

In this chapter we will develop the most frequent cases in which it is necessary the assisted intrusion by means of microscrews, how is the field in which we are working, how is the behaviour of that field in the different patients with its own characteristics, anchorage possibilities, the control of the forces to use in each case, the possible varities we can find during the treatment, how to correct the mismatches on the way that can appear from the technique itself, all that the proffesional should handle to be able to decide the best option for each specific treatment
