Impaction Treatment with TADs

Temporary anchorage devices(TADs) have proven to be extremely reliable and effective in impaction treatment in various positions and many other skeletal malocclusions. Buccal shelve screws are particularly useful in the camouflage treatment of severe Class III treatment and lower anterior impaction, Ramus screws are ideal in uncovering lower deep horizontal impaction. IZC screws are recommended in the correction of Class II, upper anterior impaction and protrusion. Detailed biomechanics analysis and treatment protocols will be discussed in dealing with these challenging clinical scenarios.
