Abstract :
Introduction
A satisfactory outcome when using straight wire
devices depends on a precise representation of the
bracket's prescription, that may be the consequence of the
archwire's mechanical characteristics, the location of the
bracket, or the precision and exactness of the space.
Because obtaining the proper torque of both the anterior
and the posterior dentition is crucial and depends greatly
on the alloy qualities of the arch wire as well as a tight
connection between the slot and the arch wire. Third
order information may be lost in clinical orthodontics due
to torsional play in brackets that have already been
corrected. A few variations may inadvertently occur
within the bracket slot measurements during the
fabrication process.
Therefore, the purpose of the study was to determine
the accuracy of the bracket slot measurements provided
by various manufacturers.
Materials and Method:
The MBT 0.022 slot upper right central incisor
stainless-steel brackets from four manufacturers—
American Orthodontics (Mini Master series), JJ
Orthodontics (Orthox), Desire (Ozone series), and Koden
(Basic series)—were the subject of an in vitro
investigation. Using a stereo microscope, the brackets
were scanned, and the distal face, base, and mesial face
and base were evaluated using Image Pro analysis
software. Data was sorted and quantitatively examined.
Result:
Every bracket slot measured for this inquiry
appeared to be larger in relation to the standard value.
The bracket slot size values were the closest to American
Orthodontics' ideal values. The brackets from JJ
Orthodontics and Koden seemed to have a profoundly
substantial variance from the optimal slot size, while
desire had a large departure from the ideal slot size.
Conclusion:
This analysis revealed a difference between the
measured and expressed values of the brackets, indicating
dimension errors. Because of the distinctiveness of the slot
walls and the oversize of the space, a glaring error about
the appliance may be required through the finishing as
well as detailing phase to prevent torque control from
being lost.
