Abstract

The purpose of the present study was to evaluate the influence of different surface characteristics on bone integration of titanium implants. Hollow‐cylinder implants with six different surfaces were placed in the metaphyses of the tibia and femur in six miniature pigs. After 3 and 6 weeks, the implants with surrounding bone were removed and analyzed in undecalcified transverse sections. The histologic examination revealed direct bone‐implant contact for all implants. However, the morphometric analyses demonstrated significant differences in the percentage of bone‐implant contact, when measured in cancellous bone. Electropolished as well as the sandblasted and acid pickled (medium grit; HF/HNO 3) implant surfaces had the lowest percentage of bone contact with mean values ranging between 20 and 25%. Sandblasted implants with a large grit and titanium plasmasprayed implants demonstrated 30–40% mean bone contact. The highest extent of bone‐implant interface was observed in sandblasted and acid attacked surfaces (large grit; HCl/H 2 SO 4) with mean values of 50–60%, and hydroxylapatite (HA)‐coated implants with 60–70%. However, the HA coating consistently revealed signs of resorption. It can be concluded that the extent of bone‐implant interface is positively correlated with an increasing roughness of the implant surface.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
