Abstract
Gingival recession in its localized or generalized form is an undesirable condition resulting in root exposure. Sites exhibiting Miller Class IV gingival recession are not suitable for treatment with surgical root coverage techniques, and their prognoses are very poor with current techniques. The aim of this case report is to establish a new technique for the root coverage of severe gingival recession defects (Miller Class IV) by providing a new source of enough tissue with good blood supply using the pedicled buccal fat pad (PBFP).
The PBFP was mobilized through an incision in the base of the buccal flap at the level of the upper second molar; the vascularized flap was secured to the buccal surface of the upper first molar tooth and premolar teeth and sutured with the wound margins.
A clinically significant amount of keratinized gingiva that covered the root recession defect was obtained. Epithelialization of the buccal fat pad was completed after 6 weeks, with formation of healthy-looking keratinized mucosa in the anatomic site of the keratinized gingiva.
The PBFP technique is simple and easy to handle. It may also be considered a novel application with promising results for the root coverage of severe gingival recession defects (Miller Class IV) that may provide a considerable amount of keratinized tissue used for root coverage of the upper posterior molar teeth.
