Treatment of a Lingual Gingival Recession with Sticky Bone and Lingual Trap: A Case Report

Abstract

Guided tissue regeneration using sticky bone (particulate bovine xenograft mixed with i-PRF) and PRF membranes was applied to a lingual dehiscence of tooth 42. The case involves a patient with a lingual dehiscence caused by prolonged use of a tongue piercing, treated with biomaterials. The protocol included root conditioning with ethylenediaminetetraacetic acid (Pref-Gel), application of Emdogain, coverage with PRF membranes, and the use of a protective lingual shield. Follow-up at 8 days, 2, 4, and 6 months demonstrated favorable healing, gingival thickening, stable root coverage, and absence of recurrence. The findings are compared with the available scientific literature on guided tissue regeneration with sticky bone and PRF, as well as with different methods described for the treatment of lingual dehiscences. Finally, it is concluded that the use of biomaterials combined with autologous materials for guided tissue regeneration (GTR) yields highly favorable results, and that adjunctive devices from the orthodontic field, such as a protective lingual shield for the graft, may be employed—particularly since the lingual area poses challenges for treatment due to tongue movements.
