Comparison between collagen-based barrier membranes from different xenogeneic resources and extraction sites for Guided Bone Regeneration (GBR).
| Porcine | Bovine | |||
|---|---|---|---|---|
| Common tissue source | Dermis | Compactness of tissue hinders cell infiltration and degradation in vivo [48]. | Dermis | Compactness of tissue hinders cell infiltration and degradation in vivo [48]. |
| Pericardium | Lower tissue reaction and higher cell infiltration in vivo than dermis-derived collagen [6]. | Achilles tendon | Balanced tissue reaction and adequate cell infiltration [5]. | |
| Collagen types | I, III | I, II, IV [52] | ||
| Use in GBR | Common | Not as common | ||
| Immunogenicity | Lower [53] | Higher (3% of population is allergic) [53] | ||
| Religious limitations | In Islam | In Hinduism | ||
