Succinate-complexed Octacalcium Phosphate [PDF]

Bulletin of the Chemical Society of Japan, 1983
Abstract A succinate-complexed calcium phosphate has been synthesized by conducting the hydrolysis of α-tricalcium bis(phosphate) in the presence of succinate ions. The organic substance is considered to be introduced into the structure of the hydrolysis product, i.e., octacalcium bis(hydrogen-phosphate) tetrakis(phosphate) pentahydrate,

Octacalcium phosphate (OCP)-based bone substitute materials

Japanese Dental Science Review, 2013
The present article summarizes the characteristics of a synthetic octacalcium phosphate (OCP) and OCP-based materials. We previously established a method for a relatively large scale synthesis of OCP and showed that OCP enhances bone regeneration more ...
