The minimally invasive surgical technique (MIST) is a method for periodontal regenerative treatment by minimizing trauma so it can preserve vascular supply of the interdental papillae. This study aims to determine effectiveness MIST with addition combination hydroxyapatite and β-tricalcium phosphate (HA + β-TCP) in infrabony pockets terms alveolar bone density osteocalcin levels gingival crevic...

Abstract In this study, polylactic acid (PLA) filled with hydroxyapatite (HA) or beta-tricalcium phosphate (TCP) in 5 wt% and 10 wt% of concentration were produced employing twin-screw extrusion followed by fused filament fabrication two different architectures, varying the orientation fibers adjacent layers. The extruded 3D filaments presented suitable rheological thermal properties to manufac...

We are currently developing a small perforated titanium subperiosteal implant specifically for orthodontic therapy, which can be placed anywhere on the bone surface. In the present study, we coated this implant with hydroxyapatite (HA) or alpha-tricalcium phosphate (alpha-TCP) in an attempt to shorten the initial stabilization period relative to the few months that is usually required. The coat...

BACKGROUND The success of bone augmentation to a major degree depends on the biomechanics and biological conditions of the surrounding tissues. Therefore, an animal model is needed providing anatomical sites with similar mechanical pressures for comparing its influence on different biomaterials for bone regeneration. The present report describes the new bone formation associated to biomaterial ...

Porous materials are highly preferred for bone tissue engineering due to space for blood vessel ingrowth, but this may introduce extra experimental variations because of the difficulty in precise control of porosity. In order to decide whether it is absolutely necessary to use porous materials in in vitro comparative osteogenesis study of materials with different chemistries, we carried out ost...

Calcium phosphate- (CaP-) based composite scaffolds have been used extensively for the bone regeneration in bone tissue engineering. Previously, we developed a biomimetic composite nanofibrous membrane of gelatin/β-tricalcium phosphate (TCP) and confirmed their biological activity in vitro and bone regeneration in vivo. However, how these composite nanofibers promote the osteogenic differentiat...

Fucoidan (Fuc), a natural polysaccharide derived from brown seaweed algae, and gelatin (Gel) were conjugated to form a template for preparation of biomimetic scaffolds for potential applications in bone tissue regeneration. To the Fuc-Gel we then incorporated the peptide sequence MTNYDEAAMAIASLN (MTN) derived from the E-F hand domain, known for its calcium binding properties. To mimic the compo...

To address the clinical needs for biodegradable implant materials, in this work, zinc-lithium (Zn-Li) alloy was coated with double-doped manganese and strontium resorbable tricalcium phosphate (Mn,Sr-TCP). The Pulsed Laser Deposition method applied coating preparation. For characterization, Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy coupled Energy D...

Calcium phosphate [single-phase hydroxyapatite (HA, Ca(10)(PO(4))(6)(OH)(2)), single-phase tricalcium phosphate (beta-TCP, Ca(3)(PO(4))(2)), and biphasic HA-TCP] whiskers were formed by using a novel microwave-assisted molten salt mediated process. Aqueous solutions containing NaNO(3), HNO(3), Ca(NO(3))(2) x 4H(2)O, and KH(2)PO(4) (with or without urea) were used as starting reagents. These sol...

OBJECTIVE Moldable in situ self-stabilizing and hardening bone graft materials facilitate handling and may be suitable for membrane-free bone regeneration methods. This study aimed to compare two moldable synthetic calcium phosphate materials in a rabbit calvarial defect model. METHOD In 12 New Zealand white rabbits, four evenly distributed 6 mm diameter defects were drilled in the calvarial ...
