Notes:
The purpose of this study was to evaluate the bone interface response to different surfaceusing bone remodeling rate (BRR) under cyclic loading. The tibiae of 10 New Zealand white rabbitswere used. Each tibia of rabbits received 2 implants, one with anodic oxidation surface and theother with machined surface. Dynamic loading, a cyclic load of 100 N with 100 cycles was appliedfor 2 weeks. All implants were divided into 4 groups according to surface treatment and loading; (1)machined surface, unloaded, (2) anodic oxidation surface, unloaded, (3) machined surface, loaded,and (4) anodic oxidation surface, loaded. To determine the rate of bone formation, a series offluorochrome bone labeling materials (tetracycline, alizarin red, and calcein green) wereadministrated intramuscularly at 10, 11, 12 weeks. To study the formation time of new bone,ground sections were examined under confocal laser scanning microscopy. Resonance frequencyanalysis (RFA) values were measured at the time of first surgery, second surgery andsacrifice. From this study, it was concluded that implants with anodic oxidation surface had highervalue than machined surface on RFA measurement and anodic oxidation surface has moreresistance to loading than machined surface
