Abstract:
The use of plates for the treatment of fractures can affect craniofacial bone development. This study investigated the effect of bioabsorbable plates and titanium microscrews on the growth of the craniofacial skeleton of rabbits (Oryctolagus cuniculus), in the neonatal period. A LactoSorb plate and PROMM titanium microscrews were positioned across the coronal suture in animals in the study group. In the control group, only PROMM titanium microscrews were attached to the cranium. Anteroposterior linear measurements were obtained using 3 different gauging devices: digital precision caliper, EKG caliper and nylon string. Frontal-nasal (FN) distances were statistically different between the left and right side when the digital caliper (P
