Abstract
يتعلق الاختراع بطريقة لإعداد اسمنت فوسفاتي كلسي قابل للذوبان وقابل للاندماج العظمي للاستخدام التجبيري والاستخدام في مجال طب الأسنان.تتشكل المرحلة الصلبة من الفوسفات الرباعي الكلسي أو توليف من الفوسفات الرباعي الكلسي والفوسفات الثلاثي الكلسي النوع a و / أو b.يُستخدم الفوسفات الثلاثي الكلسي من النوع b كسلائف أو كأحد المضافات على شكل حبيبيات ذات حجم يتراوح بين 300 و 500 تتشكل المرحلة السائلة من محلول حامض أورتو فوسفوريك و كلوريد الكالسيوم. المنتج النهائي هو مادة بيولوجية مكونة من مرحلة قابلة للذوبان ذات بنية الأباتيت وذات تناسب ذري ca / p بين 1.33 و 1.67،الأفضلية بين 1.33 و 1.5 ، أو من مادة بيولوجية ثنائية المرحلة قابلة للذوبان وقابلة للاندماج العظمي مكونة من حبيبات ومن فوسفات ثلاثي كالسي من النوع b المنتشر في مصفوفة اباتيت.هدف الاختراع تركيبة للأسمنت تتميز بتماسك يُسَهل لدونتها ومرورها على شكل عجنة متلاحمة، من خلال إبرة الحقن.The invention relates to a method for the preparation of soluble and fusible orthopedic calcium phosphate cement for orthopedic and dental use. The solid phase consists of quaternary calcium phosphate or a synthesis of quaternary calcium phosphate and triple calcium phosphate type a and / or b. As a precursor or as an additive in the form of granules of a size between 300 and 500, the liquid phase consists of a solution of orthophosphoric acid and calcium chloride. The final product is a biological material consisting of an apatite-soluble phase with a ca / p atomic ratio of between 1.33 and 1.67, a preference between 1.33 and 1.5, or of a biodegradable soluble bi-phase material consisting of granules and triple calcium phosphate of the type The objective of the invention is a cement composition characterized by a coherence that facilitates its elasticity and passage in the form of a coherent embryo through the injection needle.
