Bone to implant contact, sometimes called bone implant contact, is a term that refers to how much of the implant surface is touching bone on a microscopic level and is graded as a percentage. The type of bone plays a significant role in the percentage of bone to implant contact. In soft or medium bone, stability is typically not as good. When osseointegration occurs, stability increases and therefore the percentage of bone to implant contact increases. In dense bone, stability is typically much better and when osseointegration occurs, stability typically remains the same, or it may increase slightly but not significantly. In cases of failed implants, stability is generally low and the bone to implant contact may go down as well. After a dental implant is placed, measurements are taken to determine the level of bone to implant contact and may use this information to modify the patient treatment plan.
