Treatment of complex craniofacial deformities is still a challenge for medicine and dentistry because few approach therapies are available on the market that allow rehabilitation using 3D-printed medical devices. Thus, this study aims to create a scaffold with a morphology that simulates bone tissue, able to create a favorable environment for the development and differentiation of osteogenic cells. Moreover, its association with Plenum Guide, through cell-based tissue engineering (ASCs) for guided bone regeneration in critical rat calvarial defects.

Background: Evidence has revealed that oestrogen deprivation-induced osteolysis is microbiota-dependent and can be treated by probiotics. However, the underlying mechanism require further investigation. This study aims to provide additional evidence supporting the use of probiotics as an adjuvant treatment and to explore the pathophysiology of oestrogen-deprived osteolysis.

Induced membrane technique (IMT) is a new method for repairing segmental bone defects. However, the mechanism of its defect repair is not clear. In recent years, several studies have gradually indicated that ferroptosis is closely related to bone remodeling.

Medium chained triglycerides (MCT) ketogenic diet is being extensively investigated for its neuroprotective effects against adverse effects associated with aging and neurodegenerative disorders. Aging is a common risk factor for the development of both osteoporosis and neurological disorders. Hence, suppression of aging and age-related neurodegeneration might contribute to delaying skeletal aging.

Endochondral ossification (EO) is a pivotal process during fracture healing and traumatic heterotopic ossification (HO), involving the cartilaginous matrix synthesis and mineralization. Unlike the extracellular matrix, the hyaluronan (HA)-rich pericellular matrix (PCM) directly envelops chondrocytes, serving as the frontline for extracellular signal reception and undergoing dynamic remodeling. Pentraxin 3 (PTX3), a secreted glycoprotein, facilitates HA matrix assembly and remodeling.
