Contents
• Definition
• Indications
• Contraindications
• External bevel gingivectomy
• Internal bevel gingivectomy
• Excisional new attachment procedure
• Gingivoplasty
• Healing
• Laser gingivectomy
DEFINITION
Gingivectomy means excision of gingiva
➢ By removing pocket wall, it provides visibility and accessibility
for complete calculus removal,
➢ thorough smooth ening of the roots,
➢ creates favorable environment for gingival healing,
➢ restores a physiological gingival contour.
INDICATIONS
➢ Elimination of suprabony pockets, regardless of their depth, if
the pocket wall is fibrous and firm.
➢ Elimination of gingival enlargements.
➢ Elimination of suprabony periodontal abscesses.
CONTRAINDICATIONS
➢ The need for bone surgery or examination of the bone shape
and morphology.
➢ The situations in which the bottom of the pocket is apical to
the mucogingival junction.

, ➢ Esthetic considerations, particularly in the anterior maxilla.
GINGIVECTOMY TECHNIQUE MAY BE PERFORMED BY
➢ SCALPELS
➢ ELECTRODES
➢ LASERS
➢ CHEMICALS
EXTERNAL BEVEL GING IVECTOMY OR BLACK PROCEDURE
Instruments Required
➢ Mirror, probe and dressing tweezers,
➢ Scalpel with a no -12 blade
➢ Kirkland knives
➢ An Orban knife ,
➢ Crane-Kaplan pocket markers,
➢ Periodontal hoes, Ash T.C 2L, 2R,
➢ And Mc calls curettes.
Step-1
➢ The pockets on each surface are explored with a periodontal
probe and marked with a pocket marker in several areas to
outline its course on each surface.
➢ Periodontal knives (eg -kirkland knives) are used for incisions on
the facial and lingual surfaces and those distal to the terminal
tooth in the arch.
➢ Orban periodontal knives are used for supplemental interdental
incisions, if necessary, and Bard -parker knives#11&12 and
scissors are used as auxiliary instruments.
