In vitro testing of calcium phosphate (HA, TCP, and biphasic HA-TCP) whiskers.
Calcium phosphate [single-phase hydroxyapatite (HA, Ca(10)(PO(4))(6)(OH)(2)), single-phase tricalcium phosphate (beta-TCP, Ca(3)(PO(4))(2)), and biphasic HA-TCP] whiskers were formed by using a novel microwave-assisted molten salt mediated process. Aqueous solutions containing NaNO(3), HNO(3), Ca(NO(3))(2) x 4H(2)O, and KH(2)PO(4) (with or without urea) were used as starting reagents. These sol...
متن کاملBiphasic calcium phosphates (BCP) of hydroxyapatite (HA) and tricalcium phosphate (TCP) as bone substitutes: Importance of physicochemical characterizations in biomaterials studies
The data presented in this article are related to the research article entitled "Biphasic calcium phosphates bioceramics (HA/TCP): Concept, physicochemical properties and the impact of standardization of study protocols in biomaterials research" [1]. This article provides in depth study of BCP bone substitutes as valuable option in the field of tissue engineering. However, there are discrepanci...
متن کاملComparison of TCP and TCP/HA Hybrid Scaffolds for Osteoconductive Activity
Two types of porous ceramic scaffolds were prepared, consisting of β-tricalcium phosphate (TCP) or the mixed powder of TCP and hydroxyapatite (HA) at a 2:1 mass ratio. A variety of methods have been used to fabricate bone scaffolds, while the sintering approach was adopted in this work. An extremely high temperature was used on sintering that proposed to consolidate the ceramic particles. As re...
متن کاملRidge preservation using an in situ hardening biphasic calcium phosphate (β-TCP/HA) bone graft substitute—a clinical, radiological, and histological study
BACKGROUND Post-Extraction ridge preservation using bone graft substitutes is a conservative technique to maintain the width of the alveolar ridge. The objective of the present study was to evaluate an in situ hardening biphasic (HA/β-TCP) bone graft substitutes for ridge preservation without primary wound closure or a dental membrane. METHODS A total of 15 patients reported for tooth extract...
متن کاملبررسی اثر عوامل فعال سطحی مختلف بر سنتز پودر نانو کامپوزیت β-TCP/HA
پودر نانو کامپوزیت بتا تری‌کلسیم فسفات/ هیدروکسی آپاتیت (β-TCP/ HA) از روش رسوب شیمیایی در دمای 1100 درجه سانتی‌گراد به مدت 2 ساعت سنتز و شناسایی شد و سپس تأثیر عوامل فعال سطحی مختلف بر پودر حاصل مورد بررسی قرارگرفت. ساختار بلوری و فازهای حاصل با پراش پرتو ایکس (XRD) و طیف سنجی فروسرخ تبدیل فوریه (FTIR) مورد مطالعه قرار گرفت. بررسی اندازه و ریخت‌شناسی ذرات و اگلومراسیون پودرهای به‌دست آمده توسط...
