    • The present invention relates to a percutaneous implant abutment for bone anchored implant devices adapted to be anchored in the craniofacial region of a person, such as bone anchored hearing aids. The abutment comprises a skin penetration body having a skin contacting surface. The skin contacting surface has been modified in such a way that the shear modulus of the skin contacting part of the percutaneous Iy implant abutment is reduced to less than 35 GPa. Preferably the surface of the skin contacting part of the percutaneous Iy implant abutment is coated with a bio- compatible polymer or a ceramic material with a thickness of 0.001-50 μm. As an alternative, or in combination, an enlargement treatment can be provided to the surface re¬ sulting in a 10 % surface increase and a roughness value Sa of 0.5-10 μm. By such surface modifications specific adverse skin reactions are reduced.
    • 本发明涉及适于锚定在人的颅面区域(例如骨锚固助听器)的骨锚固植入物装置的经皮植入物邻接。 基台包括具有皮肤接触表面的皮肤穿透体。 已经对皮肤接触表面进行了修改,使得经皮Iy植入物抵接部分的皮肤接触部分的剪切模量降低到小于35GPa。 优选地,经皮Iy植入物邻接部分的皮肤接触部分的表面涂覆有厚度为0.001-50μm的生物相容性聚合物或陶瓷材料。 作为替代或组合,可以在表面增加10%,粗糙度Sa为0.5-10μm的表面上提供放大处理。 通过这种表面改性,降低了特定的不利皮肤反应。
