The use of the conventional gingivectomy procedure is indicated to achieve optimum gingival contour and to eliminate supra-alveolar pockets where these do not extend beyond the muco-gingival junction. The instrument of choice for the procedure is a gingivectomy knife. Where a blood-free field is required, electrosurgery may be used provided the instrument is not brought into contact with bone. The maintenance of good oral hygiene is essential.
