Deep Margin Isolation and Deep Margin Elevation.

Deep Margin Isolation and Deep Margin Elevation.

Isolation isn’t just for Instagram — it’s essential to improving the performance of your adhesive restorations. In this new lecture, Dr David Alleman and Dr Davey Alleman share practical techniques for achieving reliable isolation in complex cases, including crown replacements and deep margins using copper bands. They also present deep margin elevation as a proven alternative to crown lengthening, supported by long-term research and clinical success. Learn how to adapt these techniques with detailed, step-by-step footage recorded through the Allemans’ high-magnification operating microscope. This is an expert-led lecture that balances practical case examples with the science behind each technique.

Aims & Objectives:

1) Understand and apply a range of isolation tools and strategies for adhesive restorative cases in deep and complex scenarios.
2) Examine long-term clinical data supporting deep margin elevation as a reliable method for managing sub-gingival defects, as an alternative to surgical crown lengthening.
3) Learn step-by-step protocols that integrate deep margin elevation with adhesive layering techniques, emphasising seal integrity and controlling polymerisation stress.
4) Develop clinical judgement in choosing restoration strategies based on the hierarchy of bondability, c‑factor control, and emerging restorative science.
