Background: Open reduction with internal fixation is the preferred treatment option for displaced facial bone fractures. The superior mechanical properties of metallic plates have made them the most widely used material in existing bone fixation systems. However, after the healing period, these permanent plates can cause various problems. Alternative bioresorbable materials are being investigated to reduce these potential problems. This study compares bone stability and viability by using graphene oxide (GO ) -doped poly -lactic -co -glycolic acid (PLGA ) nanofiber plates and titanium plates for rats with fractured mandibles. Materials and methods: The study included 20 male Sprague -Dawley rats, divided into four groups: a control group (Group I ), a mandibular fracture group with no additional application (Group II ), a mandibular fracture group repaired with titanium plates (Group III ), and a mandibular fracture group repaired with GO -PLGA plates (Group IV ). After 2 months, all of the rats were euthanized. A bone compression test was performed to assess bone stability, and a histological examination was performed to evaluate bone healing. Results: The osteocyte lacunae, Haversian ducts, canaliculi, and vascular structures of Group IV were found to be higher. In the compression test, vertical compression was applied to the bone axis, and Group IV had a higher maximum load and maximum stretch. GO -PLGA plates were found to be statistically superior to titanium plates in terms of both bone stability and bone healing (p < 0.05 ). Conclusions: The present study found that GO -PLGA plates are more effective than titanium plates for the treatment of mandibular corpus fractures.
