Gingival recession

85% of the world population has gingival recession on at least one tooth with denuded root surface ≥1.0 mm.

Many cases which are encountered in daily clinical practice cannot be classified according to the criteria of the present classification systems.

Alternatively, a material called acellular dermal matrix (processed donated human skin allograft) may be used instead of tissue from the patient's own palate.

Recent advances have seen the introduction of platelet-derived growth factor (PDGF) infused bone graft material.

This material is usually combined with the cellular matrix to form a soft bone paste that is then covered by the allograft.
