Dental implants Toronto have advanced a great deal since the 1950s, when titanium was found to be an excellent material for the posts that anchor prosthetic teeth. Prosthodontists found out quickly that the more the post is shaped like the root of an actual tooth, the quicker the bone integrates into it. Before, the posts were straight. They were also smooth, which was another characteristic that made the bone integrating into the post a long and painful process. Prosthodontists also learned that bone is much more amenable to osseointegrating into rough surfaces. Now, posts have threads like screws. Some of them are even honeycombed, which allows the bone to grow into the lacunae in the post.
