Tooth transposition
Tooth transposition means that teeth occupy exchanged positions within the dental arch. [1]
Crowns and roots
Complete transposition concerns both crown and root positions. [1]
Lorente's incomplete example had exchanged roots without exchanged crowns. [1]
Other authors describe an incomplete pattern with exchanged crowns while roots retain their usual positions. [2]
Assessment
Assessment considers tooth position, available space, supporting tissues, bite and patient priorities. [2]
In one reported patient, premolar root resorption was already present before orthodontic treatment. [3]
Choices and co-care
Options discussed include alignment in the exchanged order, correction of the order, and selected extraction approaches. [1]
Keeping the order can leave bite contact and tooth shape issues to address. [3]
Correction can require more demanding movement with risks to roots or supporting tissues. [3]
Limited space and unfavorable tooth positions contributed to an extraction choice in the multidisciplinary report. [2]
That patient's care also included restorative and gum contour treatment; those procedures are not routine requirements for every reader. [2]
Case evidence
The bilateral correction report recorded slight gum recession despite no appreciable root resorption. [1]
The Class III case reported no progression of existing resorption after carefully monitored correction. [3]
Three separate case reports do not establish comparative effectiveness, personal suitability, expected duration or a current clinical standard. [1,2,3]
