why after 20 years?..think about it
Perio disease or change in Occlusion?
Looks like this has a cantilever affecting it. Classic case of off-axis loading.
If that is a cantilever then by your standards every implant will sure fail due to clasicic “off- axis loading”. Implants are only as permanent as the permanent tooth which they are replacing and sometimes, more often when there is obvious cement dripping down the fixture, sh?+ happens and they fail. I think we should stop taking ourselves so seriously and accept reality… IMHO this so called cantilever has nothing to do with the fate of this aftermarket discount implant fixture.
No platform switch, and the dental implants are not for ever. The exces of cement could promote mucositis and perimplantitis in a long term
All of the above + I am seeing more implant failures with patients on multiple meds, esp when proton pump inhibitors and/or SSRI’s have been used more than 10 years.
