Novel highly biodegradable biphasic tricalcium phosphates composed of α-tricalcium phosphate and β-tricalcium phosphate

Acta Biomaterialia, 2007
Novel biodegradable biphasic tricalcium phosphates (BTCP) composed of alpha-tricalcium phosphate (alpha-TCP) and beta-tricalcium phosphate (beta-TCP) were successfully synthesized by heating amorphous calcium phosphate precursors with different structures at 800 degrees C for 3 h.

Beta-phosphate tricalcium colloidal processing

Ceramics International, 2020
Abstract Beta Tricalcium phosphate (β-TCP) is an important ceramic material for biomedical applications and can help the regeneration of bone. In this work, it was studied the rheological behaviour of β-TCP suspensions, using the slip casting forming method, in order to adjust the necessary conditions for future use as bone graft.

Characterization of beta-tricalcium phosphate as a novel immunomodulator

International Immunopharmacology, 2014
Calcium phosphate (CaP) ceramics including hydroxyapatite (HA) and beta-tricalcium phosphate (β-TCP) have been widely used for bone substitution in orthopedic, maxillofacial and dental surgery, as well as in tumor resections. CaP particles are also known to cause inflammatory responses, which are thought to be an unfavorable characteristic of ...

The growth of octacalcium phosphate on beta tricalcium phosphate

Journal of Crystal Growth, 1983
The crystallization of calcium phosphate phases from metastable supersaturated solutions following seeding with well characterized tricalcium phosphate (β-TCP) solid has been studied at 37°C, using the constant composition method. The results confirm that at a pH of 6.00, it is impossible to precipitate β-TCP at ambient temperatures.

Kinetics of Dissolution of β-Tricalcium Phosphate

Journal of Colloid and Interface Science, 1997
The rate of dissolution of beta-tricalcium phosphate (beta-Ca3 (PO4 )2 ; beta-TCP) has been measured in the solution system Ca(OH)2 -H3 PO4 -NaOH-HNO3 -H2 O. The effects of different parameters such as pH, temperature, time, and saturation have been investigated.

Computer graphics of hydroxyapatite and β-tricalcium phosphate

Biomaterials, 1990
Hydroxyapatite (HA) and beta-tricalcium phosphate (TCP) were studied by computer graphics with a personal computer. Crystal models of fluoridated hydroxyapatite and fluorapatite, in which F- ions are substituted into some or all OH- positions, were also drawn.

Bone bonding mechanism of β‐tricalcium phosphate

Journal of Biomedical Materials Research, 1991
AbstractIt has been proposed that the formation of a surface apatite layer in vivo on surface active ceramics is an essential condition for chemical bonding between ceramics and bone tissue. To clarify the difference in bone‐bonding mechanisms between surface active ceramics and bioresorbable ceramics, two experiments were performed using plates of ...

Frontal Sinus Obliteration With β-Tricalcium Phosphate

Journal of Craniofacial Surgery, 2004
Autogenous materials are considered the gold standard when indicated for frontal sinus obliteration; however, alloplastic alternatives obviate the need for a second surgical site, eliminate donor site morbidity, and reduce operating room time. A variety of different alloplastic materials have been used for this purpose, but no report to date has ...
