The study aims to create a reliable rat model for assessing digitally fabricated barrier membranes in guided bone regeneration.
Analyzed single-cell RNA sequencing datasets for cellular comparison between the cranium and mandible.
Established three experimental groups: cranial augmentation, mandibular augmentation, and mandibular augmentation with nutrient foramen preparation.
Assessed outcomes at 8 weeks using stereomicroscopy, micro-CT, and histology.
Mandible group achieved 86.7% survival rate and 83.3% success rate in membrane retention.
Significantly higher vertical bone gain and bone mineral density in Mandible and Mandible + NF groups compared to the Crania group.
Circular retention method ensured sufficient stability of the barrier membranes without screw fixation.
