migration rate of epithelium after gingivectomy

0.5-1mm/day

procedure of gingivectomy

45 degree bevel cut towards

Gingivectomy is indicated for 1. pseudopockets. 2. suprabony pockets. 3. fibrotic gingival enlargements. 4. infrabony pockets. A. (1) (2) (3) B. (1) and (3) C. (2) and (4) D. (4) only E. All of the above.

A

pseudopocket

A pocket formed by gingival enlargement without apical migration of the junctional epithelium

The gingivectomy approach to pocket elimination results in A. healing by primary intention. B. adequate access to correct irregular osseous contours. C. retention of all or most of the attached gingiva. D. None of the above.

C

which fibers do we cut and which ones do we preserve

cut the interdental fibers and preserve the CT bed

Open flap surgery is crown lengthening T/F

false, crowns will be longer due to therapeutic recession

medication induced gingival enlargement can only be taken care of by

gingivectomy

difference between a gingivectomy and gingivoplasty

gingivoplasty is removal of outer layer of gingiva only, more conservative

contraindications of gingivectomy

inadequate attached gingiva intrabony pocket (vertical bone loss) large wound area

Absence of what form of tissue is considered a contraindication for treatment planning a gingivectomy

keratinized/attached gingiva

benefits of gingivectomy compared to open flap surgery

no flap--> no bone exposure--> no bone loss

indications for gingivectomy

pocket retention after SRP, areas will excessive fibrotic tissues, medication induced gingival enlargement, gingival overgrowth over the implent to expose tooth structure

criterias for gingivectomy

sufficient keratinized gingiva after gingivectomy, no significant bone loss (not indicated for infrabony pocket)

infrabony pocket (what type of bone loss)

the base of the pocket is apical to the level of adjacent bone vertical bone loss with multiple walls

suprabony pocket (what type of bone loss)

the base of the pocket is coronal to the level of underlying bone bone loss is horizontal

result of gingiva after gingivectomy

therapeutic recession of the gingiva and will create a 1-3mm probing depth

indications of gingivoplasty

trimming the gingiva around a new restoration creating ovate ponti receptor site for natural emergence profile
