3. Introduction
• One of t he long t erm desires of
Periodont ist s ---able t o cover denuded
root surf aces.
• Pat ient awareness and expect at ions have
increased recent ly t o t he point t hat less

Marginal Tissue Recession – Maynard and
Wilson(1968)
Periodont al Recession – Sant arelli GA et al (2001)
• Gingival recession is def ined as t he locat ion of
marginal t issue apical t o cement o-enamel
j unct ion wit h exposure of root sur f ace.

– Fault y t oot h br ushing t echnique
– Toot h malposit ion
– Gingival inf lammat ion
– Abnor mal f r enal at t achment
– Tr auma f r om occlusion
– Masochist ic habit s
– Frict ion f rom sof t t issues
– I at rogenic dent ist ry
6. Classifications of gingival
recession
• 1968 – Sullivan and At kins
• 1978 – Mlineck
• 1980 – Liu and Salt
• 1983 – Bengue et al.,
• 1985 – Prest on D Miller J r
• 2010 – Mahaj an’s Modif icat ion
8. Patient Evaluation
Assessing t he amount of root coverage
t hat can be achieved requires
Width of the defect,
Evaluation of the height of the
interproximal tissues,
Allen f ound t hat width is inversely

12. AIM : To demonst rat e a novel t echnique t hat ut ilizes
t he per iost eum as an aut ogr af t f or t he t reat ment
of gingival recession def ect .
The adult human periosteum is a highly vascular
connect ive t issue wit h immense r egenerat ive

Gingival Recession :Millers Class–I
{Recession Depth –4mm, Recession Width – 3.5mm}
Probing Depth – 0.5mm
Width Of Keratinized Gingiva – 1mm
15. Technique
A.Horizontal & vertical incisions placed
B.2 mm of Alveolar bone exposed
C.Periosteum is reflected from the apical end, leaving the coronal end intact
D.Periosteum is reversed over the recession defect
E.Coronal advancement of partial thickness flap done
16. • Horizontal & vertical incisions placed
Technique• 2 mm of Alveolar bone exposed
Periosteum
Partial thickness flap
Exposed alveolar bone
17. Technique
• Periosteum is reflected from the apical end,
leaving the coronal end intact
• Periosteum is reversed over the recession defect

22. • The periost eum, which is a highly vascular
t issue, is comprised of 2 layers, an inner
cellular or cambium layer and an out er
f ibrous layer
• Wound healing af t er mucogingival surgery
relies on clot t ing, revascularizat ion, and
maint enance of blood supply. Also,Hwang DL, Wang : J Periodontol 2006;77:1625-1634.
23. I n addit ion, having an adequat e vascularit y
prevent s t he necrosis of PPG even if it is
lef t uncovered by t he overlying f lap,
especially in t he case of a large area of
gingival recession.
