The results show that using Zn-containing palatal stent (Elemental) after free gingival graft surgery significantly reduces pain and patient morbidity during the postoperative period.
The study also revealed that the Zn-containing stent promoted a faster re-epithelialization rate.
The patients in the Zn-S group (Elemental) had a considerably shorter overall surgical time and donor site surgical time than the HA-S group.
