The focus of this work is to understand the influence of Sr ions on the physicochemical properties of resorbable biphasic calcium phosphate (BCP) bioceramics composed of a controlled mixture of hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP) with special emphasis toward degradation. It has been established that HAp and β-TCP differ in degradation rates. β-TCP shows good ability to biodegrade up to 10-20 times faster than HAp, but in an unpredictable manner, so it may not provide solid scaffolding for new bone formation. However, BCP is able to gradually degrade, leaving room for natural bone. In this work, at constant Ca/P ratio, we have varied Sr content and studied physicochemical properties and degradation behaviour of those compositions.
