Collagen Membrane
A resorbable barrier membrane derived from collagen, used in guided tissue regeneration or guided bone regeneration procedures to exclude non-osteogenic cells from a defect site.
Full Definition
Collagen membranes are bioresorbable barriers fabricated from purified Type I and/or Type III collagen, sourced from bovine or porcine dermis or pericardium, and used in periodontal and implant surgery to physically separate healing compartments. Placed over a bone graft or defect, the membrane prevents epithelial and connective tissue cells from populating the space intended for periodontal ligament or bone regeneration. Resorbable collagen membranes eliminate the need for a second surgical procedure required for non-resorbable membranes (e.g., expanded polytetrafluoroethylene, ePTFE). Editors should note that the source species (bovine/porcine) may be clinically and ethically relevant and should be accurately reported in clinical manuscripts. The term is always written as two words.
Usage
Usage note: Always specify the source species when editing clinical manuscripts. Distinguish resorbable collagen membranes from non-resorbable ePTFE membranes, which require a second surgery for removal.
In Context
- "A bovine-derived collagen membrane was placed over the particulate bone graft to stabilise the material and exclude epithelial ingrowth." — Surgical procedure note — guided bone regeneration
- "The manuscript must specify whether the collagen membrane used was of bovine or porcine origin, as this is relevant for patients with dietary restrictions." — Manuscript review comment
