Abstract

The purpose of this study was to prepare resorbable α-calcium sulfate hemihydrate/amorphous calcium phosphate (α-CSH/ACP) bone substitute with a resorption period of 3-6 months specifically designed for dental implantation surgery. A one-pot process was used to manufacture α-CSH and ACP. Granular particles of α-CSH/ACP (60/40) with diameters of 420-840 μm were prepared. In dissolution test, both α-CSH/ACP (60/40) and CSD displayed rapid dissolution in the first 20 days, followed by a remarkably slow dissolution rate to reach weight retention plateaus of around 13.5%±0.7% and 40.5%±1.4% at 90 days, respectively. The in vivo study showed no adverse effects as a consequence of any of the implanted materials. After 3 weeks, the defects treated with α-CSH/ACP (60/40) showed more new bone formation (21.1%) than the empty control (13.6%) (p
