Simple excision of the epulis fissuratum results in loss of sulcus dept hand scar formation, hence the peripheral seal of full denture are obstructed. In order to avoid these condition, lyophilized porcine skin or dermis were used to excised surface for wound dressing, and treatment dentures were inserted one week after the operation which act as a splint maintaining sulcus depth. Furthermore, occlusal correction, which included to restore an optimal vertical dimension of occlusion of the old dentures, and correction of the extent of the tissue coverage by the old denture base were accomplished by modifying the old (treatment) dentures.
Consequently, it seems that loss of sulcus depth and scar formation were reduced. The ridge relation was improved, and this improvement faciliated the eventual registration of the jaw relation.
In broad lesion, it is difficult to correct the extent of tissue coverage by the resin bordermolding materials. Therefore, the extent of tissue coverage of old dentures without lesion by the impression technique before operation, and refitting the excised surface by instant chairside reline technique after the operation, it may be useful for the resolution of this difficulty.
