What is the difference between a screw retained crown and a cement retained crown?

The dental implant is the part which is fused to the bone and placed in the initial surgical visit. Normally a small healing cap is placed through the gum to allow it to heal nicely. After the bone has fused to the implant, a post (abutment) is screwed into the implant and a crown bonded or cemented to the post. This is the most common way of making a tooth. It is also possible to make the abutment and crown from a single piece. There is then a screw hole in the crown which allows it to be held in place. After the crown is screwed in the hole is filled in with a white filling material. On a full lower jaw placement the implants are screw retained and on the upper they are often cemented.
