bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...
Citrate based polymer poly(octamethylene citrate) (POC) has shown promise when formulated into composite material containing up to 65 wt% hydroxylapatite (HA) for orthopedic applications. Despite significant research into POC, insufficient information about the biocompatibility of the monomers 1,8Octanediol and Citrate used in its synthesis is available. Herein, we investigated the acute cytoto...

Bioactive ceramics have been used clinically to repair bone defects owing to their biological affinity to living bone; i.e. the capability of direct bonding to living bone, their so-called bioactivity. However, currently available bioactive ceramics do not satisfy every clinical application. Therefore, the development of novel design of bioactive materials is necessary. Bioactive ceramics show ...
Bioactive materials have evolved over the past three decades from relatively specialized, highly biocompatible, but low-strength dental materials to new compositions for expanded use in restorative dentistry. The objective of this review is to understand the concept of bioactivity and to compare and contrast the various bioactive materials while shedding light on new applications for this evolv...
For thirty years it has been known that certain compositions of Na 2 O-CaO-P 2 O 5 -SiO 2 glasses will form a mechanically strong, chemical bond to bone. These materials have become known as bioactive glasses and the process of bonding is called bioactive fixation. Bioactive glasses are widely used clinically in the repair of bone defects. Recent research at the Imperial College Tissue Engineer...
BACKGROUND The use of different bioactive materials as coating on dental implant to restore tooth function is a growing trend in modern Dentistry. In the present study, hydroxyapatite and the bioactive glass-coated implants were evaluated for their behavior in osseous tissue following implantation in 14 patients. MATERIALS AND METHODS Bioactive glass and hydroxyapatite formulated and prepared...
