Micro and nanostructural properties are believed to play a critical role in the osteoinductive capacity of bioceramic bone scaffolds. Physical characteristics also play an important role for optimum biological performance, including osteoconductivity and strength. In this study microstructural and nano-mechanical properties of a bioceramic bone scaffold were investigated as a function of the si...

This review focuses on bone substitute composites made by mixing ceramic biomaterials with fibrin sealants. Different biomaterials such as coral, bone-derived materials, bioactive glass ceramics, and synthetic calcium phosphate have been mixed with fibrin sealant, resulting in a combination of the biological properties of the two components. This type of association has not produced identical r...

Biomaterial and scaffold development underpins the advancement of tissue engineering. Traditional scaffolds based on biodegradable polymers such as poly(lactic acid) and poly(lactic acidco-glycolic acid) are weak and non-osteoconductive. For bone tissue engineering, polymer-based composite scaffolds containing bioceramics such as hydroxyapatite can be produced and used. The bioceramics can be e...

UNLABELLED The main post-polio syndrome (PPS) symptoms are new-onset weakness, new-onset atrophy, fatigue, cold intolerance, and pain associated with sleep disturbances. The polysomnographic study is the gold pattern to analyze sleep disorders. OBJECTIVE To assess pain, intolerance to cold and periodic limb movements (PLM) index before and after the use of MIG3 bioceramic fabrics over 4 weeks...

This paper describes a rapid prototyping (RP) technology for forming a hydroxyapatite (HA) bone scaffold model. The HA powder and a silica sol are mixed into bioceramic slurry form under a suitable viscosity. The HA particles are embedded in the solidified silica matrix to form green parts via a wide range of process parameters after processing by selective laser sintering (SLS). The results in...

Calcium polyphosphate (CPP) bioceramic with different porosities were prepared by controlling the concentration of the pore-foaming agent. Effect of porosity (0%, 15%, 30%, 45% and 60%) on the microstructure, pores interconnection, dissolution behavior and compressive strength of CPP bioceramic were investigated. Scanning electron microscope (SEM) and capillarity test results indicated that CPP...

This study used micro-CT to compare three obturation techniques with respect to void occurrence in canals filled with bioceramic sealer. Thirty extracted first mandibular premolars were prepared with a ProTaper Universal system and randomly allocated to three groups. Canals were obturated with gutta-percha and bioceramic root canal sealer, using either single-cone, lateral compaction, or Therma...
