Deep Margin Elevation (DME)
Save Teeth with Deep Defects: Expert Deep Margin Elevation
Deep Margin Elevation (DME), also known as Cervical Margin Relocation, is a conservative, modern technique that allows us to save teeth previously deemed "unrestorable" due to deep decay, cracks, or defects extending far below the gumline.
What is Deep Margin Elevation?
When tooth defects extend deep beneath the gum (sub-gingival margins), traditional treatment required invasive surgical crown lengthening a procedure involving gum and bone removal, significant cost, and extended healing time.
DME repositions the deep margin upward (coronally) using specialized composite resin, offering critical advantages:
Benefits of DME:
- Avoids invasive surgery - No crown lengthening required
- Preserves tooth structure - Conservative approach maintains healthy tissue
- Enables successful isolation - Critical for both root canal treatment and definitive restoration bonding
- Predictable restoration - Creates ideal conditions for crown or onlay placement
- Cost-effective - Eliminates surgical fees and healing time
International Expertise:
Dr. Nathani's mastery of this technique is formalized by his authorship of the "Isolation" chapter (featuring Deep Margin Elevation) in the prestigious textbook Clinical Fixed Prosthodontics. This textbook contribution confirms his status as an international authority in both endodontic isolation and complex restorative procedures.
Ideal for:
- Teeth with deep sub-gingival decay
- Deep fractures below the gumline
- Defective margins on previously restored teeth
- Cases where crown lengthening surgery is contraindicated
The DME Advantage for Referring Dentists:
Unlike many endodontists, Dr. Nathani's dual expertise ensures the entire treatment from endodontic access to final restoration preparation is managed with expert knowledge, maximizing the tooth's long-term prognosis and creating ideal conditions for your definitive restoration.
