title: Bone Response to Four Dental Implants with Different Surface Topographies: A Histologic and Histometric Study in Minipigs.
abstract: This study evaluated four implant surfaces in a minipig model: (1) Kohno Straight dual-engineered surface (DES) (Sweden & Martina); (2) SLActive (Straumann); (3) SM Biotite-H coated with Brushite (DIO); and (4) UF hybrid sandblasted and acid etched (HAS) (DIO). The surfaces presented different topographic features on the macro-, micro-, and nanoscales. After 12 weeks in vivo, significant differences were observed in bone-to-implant contact. UF HAS, presenting moderate microroughness and high nanoroughness, showed some advantage compared to nanorough SM Biotite-H and SLActive. A more pronounced difference was observed between UF HAS and Kohno Straight DES, characterized by a nanosmooth surface. Newly formed bone was observed around all surfaces.
