Subepithelial Connective Tissue Graft (SCTG) vs. De-epithelialized Graft: Which to Choose?
Learn why the presence of Lamina Propria makes the difference between long-term stability and late-stage complications like cysts and keloids.
Clinical Overview
In this clinical deep-dive, Dr. Snježana Pohl addresses one of the most debated topics in contemporary soft tissue surgery: the choice between the Subepithelial Connective Tissue Graft (SCTG) and the De-epithelialized Gingival Graft.
While de-epithelialized grafts have gained significant traction on social media due to their "pink" aesthetic and perceived density, the biological reality is more complex. Dr. Pohl analyzes the histological differences between Lamina Propria (dense, stable fibrous tissue) and Submucosa (glandular and fatty tissue), explaining why the graft's origin dictates its long-term volume retention and complication profile. This session moves beyond the "trend" to look at the 10-year data regarding late-stage complications such as epithelial invagination, cysts, and keloid formation.
Key Learning Objectives
- Biological Rationale: Distinguishing between Lamina Propria and Submucosa for predictable outcomes.
- Complication Prevention: Identifying the risks of residual epithelium and the "Harris Study" findings.
- Surgical Nuance: Mastering the Single Incision technique to preserve vascularity.
- Case Selection: Knowing when the "social media trend" of de-epithelialization is a biological risk.

Expert Insight
"The most critical window for preventing palatal hematomas is the moment the anesthesia wears off. Instruct your patients to apply firm pressure with a wet gauze for 30–60 minutes specifically when they start to feel sensation returning. This counteracts the reactive hyperemia caused by the adrenaline effect wearing off—a simple step that significantly reduces post-operative morbidity."

Tunnel vs. VISTA: Choosing the Right Approach for Recession Coverage
Explore the critical decision-making process between sulcular (Tunnel) and vestibular (VISTA) approaches for recession coverage. Dr. Snježana Pohl explains why tunneling is her "gold standard" for invisible scarring, while providing a transparent look at the post-operative swelling and phenotype risks that might make VISTA the safer clinical choice.
Partial Extraction Therapy (PET): Why Biology Beats Bone Grafting
Discover why retaining the root membrane is the biological key to permanent ridge maintenance. Dr. Snježana Pohl explains how Partial Extraction Therapy (PET) utilizes the periodontal ligament to nourish buccal bundle bone, offering a superior alternative to traditional bone grafting.
