Failure of a dental implant is often related to the failure of the implant to osseointegrate correctly with the bone, or vice versa. [4] A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after.

If the abutment screw becomes loose the final restoration cannot be removed without destroying it in many instances. This results in a remake and increased cost. Two, excess cement along the implant surface can potentially act as a medium for colonization by bacteria and can jeopardize the attachment, ultimately resulting in implant failure.
Cumulative interceptive supportive therapy, a protocol of therapeutic measures, provides guidance for clinicians to decide which regime should be used to treat peri-implantitis, depending on the mucosal condition (whether there is a presence of dental plaque, bleeding on gentle probing, suppuration), peri-implant probing depth, and evidence of ...
The primary use of dental implants is to support dental prosthetics (i.e. false teeth). Modern dental implants work through a biologic process where bone fuses tightly to the surface of specific materials such as titanium and some ceramics. The integration of implant and bone can support physical loads for decades without failure. [10]: 103–107
Metallosis has also been observed in some patients either sensitive to the implant or for unknown reasons even in the absence of malpositioned prosthesis. Though rare, metallosis has been observed at an estimated incidence of 5% of metal joint implant patients over the last 40 years. Women may be at slightly higher risk than men.
It has been suggested that tooth autotransplantation may be a successful alternative to osseointergrated dental implants in growing patients, as osseointergrated dental implants are contra indicated in growing patients as they do not grow down with the developing dentition and become fused to the bone.
