The eggshell membrane as a barrier membrane for guided bone regeneration.

Background: The eggshell membrane (ESM) is a natural resource with a distinct design and composition, offering structural features consistent with barrier membranes used in guided bone regeneration (GBR), making it a promising candidate for this application. This study aims to assess the feasibility of chicken and duck ESMs as GBR alternatives by comparing them with resorbable porcine-derived collagen (Porcine CM, Bio-Gide®) and non-resorbable dense polytetrafluoroethylene (d-PTFE, Cytoplast).

Methods: ESMs were extracted using a standardized protocol.
