Implant success
1) An individual, unattached implant is immobile when tested clinically.
2) A radiograph that does not demonstrate any evidence of perimplant radiolucency.
3) Vertical bone loss is less than 0.2mm annually following the first year of service of the implant.
4) Individual implant performance is characterized by an absence of persistent or irreversible signs and symptoms such as pain, infection, neuropathies, paresthesia, or violation of the mandibular canal.
5) In the context of foregoing, a success rate of 85 per cent at the end of a 5- year observation period and 80 per cent at the end of a 10 year period are minimum criteria for success.
