This patient, a 50 year old female, lost an upper bicuspid tooth. In the x-ray on the left, you can see exactly where the tooth was (this x-ray was taken only a few weeks after the tooth was extracted so the bone has not healed in yet) noting the shape of the root which goes right up to the floor of the maxillary sinus.The x-ray on the right shows the titanium implant in place and a new porcelain-fused-to-gold crown on the implant effectively replacing the missing tooth. This x-ray was taken after the "tooth" had been in function for one year.
