Case Example: Use Microimplant screw for Anchorage
|Premolars are tough teeth to deal and small deviation
of these teeth can cost a lot of time, money and energy. This is a simple case
of maxillary premolar rotation but shows the efficiency and SPEED of MIA anchorage. It was decided to treat this case as
NON extraction. Bite was deep and we decided to open the bite and just close max
anterior spaces. Fig A
Challenge was to correct the rotation of max right
premolar. We had to apply a couple, one Force from distal and one from Mesial.
We did not want to load molar and take the risk of loosing a precious 1-2 mm. So
we decided to use a 1.2mm dia 7 mm long titanium screw.. It was placed under
local anesthesia and loaded immediately. Fig B
It was quite a severe rotation of about 75degrees See fig C, and we wanted to
gain space for anterior retraction by doing this derotation.
With the help of screw the premolar rotation was easily corrected in 8 weeks
time helping us to manage the case easily without loosing molar anchorage or
using any other complicated devices.
