Dr. Justin Moody discusses implant success or failure and how to prevent possible glitches from occurring.
Dr. Justin D. Moody reflects on a patient’s 2-year-old implant
Seems everyone has a specific criterion for what success and failure looks like. Some judge it on the implant health, others on the soft tissue condition, and yet others on the prosthetic outcome. Truth is that it should be a view of all three of these criteria, and the overall status can be several outcomes.
I recently took care of a patient from one of my referral doctors. Having placed this implant over 2 years ago, he sent the patient my way as he was unable to remove the screw from the TiBase and was afraid to strip the hex. The first issue is that we had a debonded zirconia crown from a stock TiBase, and my first thought is always why. What was the “why” here? After 2 years, you would not expect this to happen. The answer is that the patient was eating some very sticky candy, so I will take this as the “why,” considering there were minimal cantilevers, and the position of the implant seemed to be good. Prosthetic failure for sure.
Next, we removed the screw and the TiBase from the mouth. The doctor was having an issue as there was debris inside the hex not allowing the driver to fully seat. Once removed, we cleaned the internal hex with chlorhexidine and placed a healing abutment to allow the soft tissue to be impression-ready for the referring dentist. So we have a soft tissue win here as the biotype is thick with no disease.
Finally, let us look at the bone levels on the PA. After 2 years, we can see that bone has grown up over the platform switch bevel of this BioHorizons® Tapered Plus implant. This is also a win as the bone levels have actually improved from the time of placement.
What’s next? Can we possibly prevent this from reoccurring? Yes, one solution that was suggested was a new screw-retained crown, this time with a full titanium abutment and full contour zirconia bonded to it.
Perhaps we should view or categorize our success and/or failures differently going forward to more accurately represent what is going on.
