Fusion with a titanium mesh cage (TMC) has become popular as a conventional method after cervical anterior corpectomy, but postoperative TMC subsidence has often been reported in the literature. We designed a novel anatomic cervical TMC to reduce the postoperative subsidence rate. According to the test process specified in the American Society of Testing Materials (ASTM) F2267 standard, three-dimensional finite element analysis was used to compare the anti-subsidence characteristics of a traditional TMC (TTMC) and novel TMC (NTMC). Through analysis, the relative propensity values of a device to subside (Kp) of the TTMC and NTMC were 665.5 N/mm and 1007.2 N/mm, respectively. A higher Kp measurement is generally expected to indicate that the device is more resistant to subsidence into a vertebral body. The results showed that the novel anatomic titanium mesh cage (NTMC) significantly improved the anti-subsidence performance after anterior cervical corpectomy and fusion (ACCF), which was approximately 51.3% higher than that of the traditional titanium mesh cage.

Alveolar ridge resorption following tooth loss poses a significant challenge for successful dental implant placement. In cases of severe atrophy, bone augmentation is required to restore sufficient bone volume. This technical note outlines a detailed, stepwise surgical protocol for horizontal and vertical alveolar ridge augmentation using customized titanium mesh.

Purpose: There are no universally established guidelines for material selection in orbital wall fracture reconstruction. With an increasing preference for permanent implants, this study aimed to compare the long-term clinical outcomes of three different non-resorbable materials in reconstructing isolated orbital floor fractures.
Design: A retrospective, interventional comparative study.

Metallic biomaterials are extensively used in orthopedics and dentistry, either as implants or coatings. In both cases, metal ions come into contact with surrounding tissues causing a particular cell response. Here, we present a biofabricated tissue model, consisting of a hydrogel reinforced with a melt electrowritten mesh, to study the effects of bound and released metal ions on surrounding cells embedded in a hydrogel matrix.

Background: Posterior vault distraction osteogenesis (PVDO) is an effective treatment for multisuture and syndromic craniosynostosis. It remains unclear how well the calvarium ossifies after PVDO, especially in older patients when they have plateaued in their cranial growth phase. The purpose of this study is to report outcomes associated with PVDO across a wide range of ages at our institution.

The retrospective study aimed to compare the space-maintaining effects of sticky bone (bone graft matrix enriched with injectable platelet-rich fibrin) and titanium mesh for bone augmentation in the aesthetic zone. Patients who underwent single implant placement and had type 2/4 alveolar bone defects (buccal bone wall loss is >50% of the expected implant length) were screened for inclusion in this study. The labial bone plate width was measured at 1, 3, and 5 mm below the apical implant platform on cone beam computed tomography images taken immediately and 6 months after surgery.
