Abstract
BACKGROUNDThis case report discusses the treatment of an iatrogenic periodontal defect caused by an inadequate orthodontic appliance in a 9-year-old girl.METHODSThe multidisciplinary approach to this case consisted of periodontal treatment using a bone grafting technique to restore the 10 mm bone dehiscence. Three months later orthodontic treatment was initiated to straighten and level the central incisors. Six months later mucogingival surgery was performed to cover 2 to 3 mm gingival recession.RESULTSThe bony defects were completely filled and the 10 mm dehiscence was reduced to 4 mm. The connective tissue graft resulted in a complete coverage of the recessions and a thickening of the keratinized gingiva. The patient is still undergoing orthodontic treatment. So far, straightening of the upper central incisors and closure of the diastema are satisfactory.CONCLUSIONSInadequate orthodontic appliances can cause iatrogenic periodontal defects. A multidisciplinary approach in a well-defined sequence can restore lost periodontal tissue, thus achieving comfort, function, and esthetics.
