 To an extent, the criteria for success due to the inherent differences in the procedure have historically limited comparisons, with success of endodontic therapy defined as the absence of periapical lucency on radiographs, or the absence of visible cavity at the root of the tooth on imaging.Implant success, on the other hand, is defined by osseointegration, or fusion of the implant to the adjacent maxilla or mandible.Endodontically treated teeth have significantly less requirement for follow up treatment after final restoration, while implants need more appointments to finish treatment and more maintenance.
