The engineering, design, manufacture, and rationale for use of printed titanium shells for alveolar bone reconstruction using BMP-2/ACS/allograft are described. This is proposed as a possible improvement to the current hand-configured mesh graft technique in common use today.

Article Synopsis
- Cage subsidence can negatively affect lumbar fusion procedures, with material selection (PEEK vs. 3D-Ti) influencing this issue; the study aims to compare their subsidence rates.
- The systematic search reviewed 265 patients from three high-quality studies, focusing on cage subsidence and classified subsidence rates using a specific method.
- Results indicated that 3D-Ti cages have a significantly lower rate of subsidence compared to PEEK cages, with less severe subsidence and better overall performance.
Are we ready for virtually planned, 3D printed titanium plates for zygoma fractures? - A feasibility study of 16 post-mortem fractures.

The state-of-the-art approach to open reduction and fixation (ORIF) of zygoma fracture fragments is based on manual skills. Achieving high accuracy can be challenging. Our feasibility study on deceased body donors with artificial zygomatic fractures investigated whether virtual repositioning of the fractures and the use of customised 3D-printed titanium osteosynthesis plates was similar in accuracy to the conventional manual procedure, and whether the method was applicable in a clinical setting.

Background: Treating infectious bone defects combined with large soft-tissue lesions poses significant clinical challenges. Herein, we introduced a modified two-stage treatment approach involving the implantation of 3D-printed prostheses and flap repair to treat large segmental infectious tibial bone defects.
Method: We conducted a retrospective study of 13 patients treated at our center between April 2018 and March 2022 for tibial infections owing to posttraumatic infection and chronic osteomyelitis combined with soft tissue defects.

Due to the limited self-regeneration capacity of bone, medical interventions is often required for large segmental bone defects. In this study, the application of porous titanium alloy (Ti6Al4V) scaffold in bone defect repair was investigated. Owing to its excellent mechanical properties and biocompatibility, Ti6Al4V is a preferred choice for orthopedic implants.
