Abstract
An apparatus for studying tissue ingrowth in an implant under different experimental conditions, in particular in response to locally administered test substances is made of a bio-compatible material, preferably pure titanium, and is implanted in living bone tissue, primarily for animal experimental activities. The apparatus includes an outer portion with a central recess in which an inner portion is inserted. In the assembled state, the two portions form at least two bone ingrowth through channels which are exposed when the inner portion is dismounted, for comparative examination of the bone ingrowth promoting/retarding properties of test substances disposed in at least one of the channels.
