Summary

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.

Conditions

  • Anterior Mandibular Fracture

Interventions

DEVICE

additive plating group

Additive manufacturing is the process of creating parts by joining materials based on 3D model data, typically layer by layer, in contrast to subtractive and formative manufacturing methods. While most of the global activity in additive manufacturing currently involves polymer-based systems, there has been increasing interest and activity in fabricating metallic parts

DEVICE

subtractive plating group

In CNC machining, cutting tool removes material to achieve the desired geometry. The process involves using CAD to create the model to be machined and CAM to provide instructions to the CNC machine on how to remove the material. There are three major machining processes for material removal based on 3D models: turning, drilling, and milling. Additional subtractive manufacturing techniques, such as laser cutting, waterjet cutting, electrical discharge machining, and plasma cutting, are typically used for 2D machining
