in this study, based on a biomimetic approach, novel 3d biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. macroporous chitosan/ gelatin/β-tcp scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. the results showed that the prepared scaffolds are highly...

Fibrous hydroxyapatite, rice-like β-tricalcium phosphate and DCPA plates were synthesised by water controlled-release solvothermal process using the esterification reaction.

BACKGROUND Intraosseous lipoma remains a poorly-characterized tumor. In paticular, the natural course of intracalcaneus lipoma after conservative treatment and the appropriate surgical modalities are still quite controversial. PATIENTS AND METHODS We reviewed six symptomatic patients who underwent curettage of intracalcaneus lipoma followed by grafting of α- or β-tricalcium phosphate. An endo...

Treatment options for large osteoperiosteal defects are limited and that which are available are not ideal. Osteoperiosteal defect were created in ulnae of both forelimbs of rabbits and tricalcium phosphate implant was used to bridge the gap. Amongst the 35 implanted ulnae, one implant got dislodged. Rest of the implants showed good adherence to host bone until the final follow up. Five control...

This experimental study was carried out to investigate the effect of medical grade calcium sulphate and β-tricalcium phosphate/ hydroxyapatite on new bone formation. Additionally, the study compared these materials for infection, resorption, biocompatibility, immune reaction, fi brotic encapsulation, foreign body reaction and physical attachment. Forty, fi ve-month-old female Wistar Albino rats...

Alveolar atrophy following tooth extraction remains a challenge for future dental implant placement. Immediate implant placement and postextraction alveolar preservation are two methods that are used to prevent significant postextraction bone loss. The purpose of this study is to investigate the usefulness of hydroxyapatite / beta tricalcium phosphate (HA/BTCP) with hyaluronic acid (HY) for alv...

Calcium Phosphate cement has been the subject of intense investigation over the past few years. This study compares difference in biocompatibility between the three main phases of Ca-P, namely Hydroxyapatite, Dicalcium phosphate and β-Tricalcium phosphate. It involves composite preparation followed by cell test. Material parameters were stoichiometry (Hydroxyapatite with Ca-P ratio of 1.67, Dic...
