The Modified Adaptor™ appliance is used for minor tooth rotations and alignments of both the posterior and anterior teeth. It works like the Spring Retainer in that the teeth on the working model are carefully placed in their ideal position prior to fabricating the appliance. The unique design features a solid lingual acrylic base that is tightly contoured to all the lingual surfaces.  Buccal posterior segments are joined to the lingual via stainless steel wires, and the labial portion (covering the six anterior teeth) is joined to the posterior segments via stainless steel Omega Loops in the cuspid/bicuspid region. Once seated, this highly flexible appliance gently settles the teeth in the correct alignment. Since the Modified Adaptor™ allows for full occlusal contact of the posterior teeth, natural function aids in a rapid and secure "settling in" of the buccal segments. Unlike a Positioner, it is extremely comfortable, virtually undetectable, and can be worn full time (except while eating). Note: The Modified Adaptor is essentially a finishing retainer. No significant rotations or mesial/distal movements should be attempted with this design.
