gingivectomy Flashcards
what is gingivectomy
excision of the gingiva
indications of gingivectomy
-elimination of suprabony pockets, regardless of depth if the pocket wall is fibrous n firm
-elimination of gingivae enlargments
-elimination of suprabony periodontal abcess
-crown lengthening
(anatomical or restorative purposes)
contraindications of gingivectomy
- need for bone surgery
- bottom of pocket apical to mgj (mucogingival junction)
- esthetic considerations
- insufficient attached gingivae
gingivectomy methods
electrodes
lasers
chemicals
surgical methods-recommend
steps to surgical gingivectomy
step1: probing and market of pockets on all surfaces
step2: incisions to facial and lingual surfaces and distal to the terminal tooth in the arch (kirkland knives or goldman 11 for incisions, orban for interdental, bard parker 11,12 and scissors as auxillary instruments)
incision starts from apikal to the markings and directed coronally between base of pocket and crest on the bone, should be as close as possible to the bone without exposing it. bewel should b approx: 45 degrees resembling healthy gingivae
step3: remove the excised pocket clean the area and examine
step4: carefully curette granulation n remove any remaining calculus leavin a smooth clean surface
step5: cover the area with surgical pack
healing after surgical gingivectomy
initally: clot formation-granulation
24 h: t cells underlayer of inflammation n necrosis
3d: numerous young fibroblasts
5-14 days surface epithelization complete
complete repair: 7w
max inflammation = max gingival fluid flow =1w
what is gingivoplasty
shaping of gingiva to create physiological contours with the sole purpose of recontouring in the absence of pockets
*gingivectomy includes this reshaping
types of deformities in the gingiva
gingival clefts n craters
shelf like interdental papilla caused by ANUG
gingival enlargments
gingivoplasty can be done with…
peridontal knife
scalpel
rotary coarse diamond stones or electrodes
steps of gingivoplasty
tapering of gingival margin creating scalloped marginal outline thinning attached gingiva creating vertical interdental grooves shaping interdental papilla
