“…Different studies claimed that using a 1mm thick 3D printed-Ti plate for fracture fixation stabilized the maximum displacement and minimized the stress shielding, providing a secure environment for fracture healing. Also, when used, the mechanical properties of the 1 mm 3D printed-Ti plate were significantly better as compared to stock Ti plates of the same thickness [18,19] . The present report observed no postoperative complication, and the internal fixation with patient-specific 3D printed-Ti plates allowed for adequate intercondylar length restoration with reduced surgical duration and simplified the overall treatment procedure.…”

The principles in treating complex mandibular fractures have changed recently, although the objective of re-establishing the occlusion and masticatory function remains the same. Technological upgrades like 3D-printed customized plates and implants have replaced traditional stock plates by achieving safe and desirable anatomical and functional restoration with reduced operative time. In this case report, we aimed to design and employ customized 3D-printed titanium plates for mandibular reconstruction in a case with complex mandibular fracture. A preoperative CT scan of the patient was taken to evaluate the displacement between the fractured segments. Virtual surgical planning was done, and 3D-printed titanium plates were simulated, customized, fabricated, and placed following Champy’s line of osteosynthesis for the approximation of fractured segments and to guide the occlusion during surgery. A postoperative CT scan was taken and overlapped with the preoperative virtual surgical plan scan to assess the interfragmentary gap after reduction and the amount of deviation. The result achieved was satisfactory, with no complications reported. The use of customized 3D printed-Ti plates in the treatment of mandibular fracture had better accuracy and adaptability to the bone, avoided the need for plate bending, improved operator efficiency, and resulted in fracture reduction with satisfactory outcomes.

“…Ti alloy plates perform a crucial function in rigid internal fixation in maxillofacial surgery [ 1 , 2 ]. Although 3D-printed Ti alloy plates have long been used in clinical practice [ 10 , 11 ], previous studies still need a comprehensive evaluation of them [ 2 , 12 , 13 ]. Therefore, the present study aimed to evaluate the mechanical properties, surface morphology, biocompatibility, and application accuracy of the 3D-Ti plates by comparing them with the Synthes-Ti plates.…”

“…The thickness of 3D-Ti plates for fracture fixation should be 1 mm [ 10 ]. At the same thickness, the mechanical properties of 3D-Ti plates were significantly better than those of standard Ti plates [ 13 ]. In this experiment, two Ti plates with a thickness of 1 mm were used to obtain the same experimental results.…”

Titanium (Ti)-based implants play a significant role in rigid internal fixation in maxillofacial surgery. No study has reported that three-dimensional-printed Ti alloy plates (3D-Ti plates) have comprehensively excellent properties similar to standard plates (Matrix-MANDIBLE, SYNTHES, Switzerland) (Synthes-Ti plates). In this work, we manufactured 3D-Ti plates by selective laser melting with Ti6Al4V powder. The surface morphology, mechanical properties, and bone–plate contact rate of the 3D-Ti plates and the Synthes-Ti plates were characterized and compared via electron microscopy, atomic force microscopy, Vickers hardness test, three-point bending test, and software calculation. Human bone marrow stromal cells (HBMSCs) were cultured on the plates to test their biocompatibility. Importantly, the 3D-Ti plates were placed into a mandibular fracture model to assess the effect of medical application for 4 and 24 weeks. The 3D-Ti plates were demonstrated to have similar biocompatibility and stability for rigid internal fixation with the Synthes-Ti plates, lower roughness (106.44 ± 78.35 nm), better mechanical strength (370.78 ± 1.25 HV10), and a higher bone–plate contact rate (96.9%). These promising results indicate the feasibility of using 3D-Ti plates for irregular shapes and complex anatomical structures in a clinical context.

“…In oral and maxillofacial surgery, the nite element method is widely used in biomechanical research such as the mechanical mechanism of fracture occurrence [3] and stability analysis after fracture xation [4]. Before nite element analysis, three-dimensional reconstruction of the corresponding anatomical structure is required.…”

Objective To study an accurate, efficient, and fast method for creating a three-dimensional finite element model using a combination of oral soft and hard tissue images obtained from various field of view CBCT scans and intra-oral 3D scan. METHODS An adult female volunteer was selected, and the mandible was scanned using two different field of view CBCT scans, the resulting images were imported into Mimics, Blue Sky Bio, and 3-Matic software using DICOM format, then it was used to create models of the teeth, periodontal ligament, and mandible bone, respectively. The oral soft tissues and dental arch were scanned using an intra-oral digital scanner. The obtained scans were processed using Geomagic and 3-Matic software to create a gingival model. The created model was meshed, and a three-dimensional finite element model consisting of a tetrahedral mesh was generated. RESULTS A comprehensive finite element model consisting of the mandible, dental arch, periodontal ligament, and gingiva was established. The model comprised a total of 222,873 nodes, with the following distribution: 892,871, 40,358, 405,043 and 234,224 for the mandible bone, periodontal ligament, teeth and gingiva, respectively. CONCLUSION The modeling method based on different field of view CBCT scans and Intra-oral scan can establish a comprehensive finite element model of the mandible bone and gingiva, which is more accurate, faster, and has a wide range of applicability.
