When intra-oral lesions in soft tissue reach the gingival margin, they
can produce aesthetic problems during its presence and after its removal.
Periodontal plastic surgery can be used in the correction of the gingival
contour using many different techniques. This is a case report of a peripheral
ossifying fibroma removal in the interproximal area between maxillary left
central and lateral incisors in addition to the coverage of the exposed root of
the affected area by using two surgical stages: first one is keratinized gingival
tissue augmentation surgery with free gingival graft concurrent with removal
of the lesion and, in a second stage, root coverage by performing coronally
repositioned flap technique with a follow-up of one year. The initial results
achieved, which were root coverage of 100% after 6 months, promoted an
adequate gingival contour and prevented the development of a mucogingival
defect or a root exposure with its functional and aesthetic consequences.
After one year, the results showed long term success of the techniques,
where the margin remained stable with complete root coverage and tissues
were stable and normal in color.
