This study aims to compare the mechanical properties, including tensile strength, shear strength, and flexural strength, as well as the clinical outcomes of additive and subtractive manufacturing techniques used to fabricate custom-made plates for the fixation of interforaminal mandibular fractures. A total of 16 patients were included and allocated into two groups: one treated using plates fabricated with the additive manufacturing technique and the other with the subtractive manufacturing technique. Mechanical performance was evaluated using standardized biomechanical testing, while clinical outcomes were assessed during scheduled postoperative follow-up visits. The objective of the study is to determine which fixation approach provides superior biomechanical performance and favorable clinical healing outcomes.
