This video demonstrates a novel approach to membrane fixation using biodegradable magnesium pins on a surgical model. The procedure illustrates the step-by-step positioning and stabilization of a regenerative membrane, focusing on the handling, insertion, and mechanical retention provided by magnesium pins. Particular attention is given to the correct positioning of the membrane, pin placement, and achievement of stable fixation while minimizing surgical complexity. The demonstration highlights the practical advantages of magnesium-based fixation as an alternative to conventional fixation systems and provides a reproducible protocol that can be readily translated into clinical practice. The video aims to provide clinicians with a clear and practical understanding of the technique and its potential role in guided bone regeneration procedures.
