A new design for bone implants, the bottle brush. was recently presented in a pilot study on marrow cavities in the femur of rabbits. In this study, the concept is further evaluated on a mini bottle brush. The fixture, 5x7 mm, with an implant shaft made of CP‐titanium and bristles of nylon coated with sputtered titanium, was inserted into the cancellous bone of the medial femoral condyle in 15 adult rabbits. The titanium fixture was compared with a similar brush without the titanium sputtered surface. The animals were sacrificed after 4 months and the quantity and quality of bone integration were evaluated with pull‐out tests and histological examination. In both parameters, the values were significantly higher for the titanium‐sputtered brushes, with removal forces similar to titanium cylinders of the same size and with a bone‐to‐metal contact area of about 50%.
