The difference between these two x-rays should be real obvious... The problem is that I see way more radiographs like the one on the left coming into my office than the one on the right. A little case-history here.... I had placed these three implants about three months prior to these radiographs. The patient was seeing one dentist who I was confident could restore this situation, but she decided to switch to another dentist. The second dentist took the radiograph on the left and sent it to me because he thought there was a problem with the implants. I looked at it and was real curious to see what was really there so I called the patient and had her come to my office and had one of my dental nurses take the radiograph on the right.These implants were placed in a one stage mode so there was no countersinking or any attempt to "bury" the implant. The idea here is to keep the threads of the implant within the limited amount of bone that we have present. As long as the radiographic procedures are acceptable, we can place and evaluate the implants properly. When the radiographic principles are violated.... Phhhttt!
