Background. Scientific evidence in the field of implant dentistry of the past 20 years established that titanium rough surfaces have shown improved osseointegration rates. In a majority of dental implants, the surface microroughness was obtained by grit blasting and/or acid etching. The aim of the study was to evaluate in vivo two different highly hydrophilic surfaces at different experimental times. Methods. Calcium-modified (CA) and SLActive surfaces were evaluated and a total of 18 implants for each type of surface were positioned into the rabbit articular femoral knee-joint in a split model experiment, and they were evaluated histologically and histomorphometrically at 15, 30, and 60 days of healing. Results. Bone-implant contact (BIC) at the two-implant surfaces was significantly different in favor of the CA surface at 15 days ( = 0.027), while SLActive displayed not significantly higher values at 30 ( = 0.51) and 60 days ( = 0.061). Conclusion. Both implant surfaces show an intimate interaction with newly formed bone.

Abstract
Background. Scientific evidence in the field of implant dentistry of the past 20 years established that titanium rough surfaces have shown improved osseointegration rates. In a majority of dental implants, the surface microroughness was obtained by grit blasting and/or acid etching. The aim of the study was to evaluate in vivo two different highly hydrophilic surfaces at different experimental times. Methods. Calcium-modified (CA) and SLActive surfaces were evaluated and a total of 18 implants for each type of surface were positioned into the rabbit articular femoral knee-joint in a split model experiment, and they were evaluated histologically and histomorphometrically at 15, 30, and 60 days of healing. Results. Bone-implant contact (BIC) at the two-implant surfaces was significantly different in favor of the CA surface at 15 days ( = 0.027), while SLActive displayed not significantly higher values at 30 ( = 0.51) and 60 days ( = 0.061). Conclusion. Both implant surfaces show an intimate interaction with newly formed bone.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
