Anatomical and mechanical properties of swine midpalatal suture in the premaxillary, maxillary, and palatine region

Abstract The mechanical properties of the midpalatal suture and their relationship with anatomical parameters are relevant for both tissue engineering and clinical treatments, such as in sutural distraction osteogenesis. Soft tissues were dissected from ten swine heads and the hard palate was sliced...
