ß-tricalcium Phosphate Granules as an Alternative Material for Ocular Implantation

ß-tricalcium phosphate granules as an alternative material for ocular implantation

background: some types of implants used for orbital implantation have side effects and complications. in this study we have evaluated beta-tricalcium phosphate (ß-tcp: chronos) granules as an orbital implant.   methods: eighteen rabbits randomly allocated to four groups. right eye enucleation performed in groups i to iii followed by filling with autologous bone particles (n=5), a mixture of aut...

Acid Neutralization Capacity of a Tricalcium Silicate-Containing Calcium Phosphate Cement as an Endodontic Material

A calcium phosphate cement (CPC) was shown to have the necessary attributes for endodontic materials except adequate basicity needed for antimicrobial properties. To enhance its basicity, tricalcium silicate (Ca3SiO5), a highly alkaline compound, was added to CPC at a mass fraction of 0.25, 0.5 or 0.75. The basicity, acid neutralization and physical properties of the CPC-Ca3SiO5 composites were...

Tricalcium phosphate (α-TCP) and polymethylmethacrylate (PMMA) implantation

Bone loss induced by inflammation is one of the complications after biomaterial implantation. There is no much data on expression of cytokines and defensins into the bone tissue around the implants in literature. The aim of this work was to investigate the distribution and appearance of interleukin (IL)-1, IL-6, IL-8, IL10 and β – defensin (BD)-2, BD-3, BD-4 after the implantation of different ...

Implantation of Tetrapod-Shaped Granular Artificial Bones or β-Tricalcium Phosphate Granules in a Canine Large Bone-Defect Model

We investigated biodegradability and new bone formation after implantation of tetrapod-shaped granular artificial bone (Tetrabone®) or β-tricalcium phosphate granules (β-TCP) in experimental critical-size defects in dogs, which were created through medial and lateral femoral condyles. The defect was packed with Tetrabone® (Tetrabone group) or β-TCP (β-TCP group) or received no implant (control ...

ß-Tricalcium Phosphate Implants in the Surgical Treatment of Empty Nose Syndrome.

The objective of this study was to assess the efficacy and morbidity of a β-tricalcium phosphate implant in the treatment of empty nose syndrome after turbinectomy. Only patients with a history of inferior turbinectomy and a complaint of permanent paradoxical nasal obstruction were included. β-Tricalcium phosphate ceramic implants were implanted under the mucoperiosteal plane of the lateral nas...
