Can My Failed Implant Be Salvaged? Bone Loss on the Outside of the Implant

Yes: when a dental implant is losing bone on its buccal (outside) surface, it can often be saved, and this particular failure pattern is one of the more favorable ones to treat. The defect sits on one wall of the implant while the remaining surfaces stay anchored in bone, which gives a meticulous repair something solid to build against.

Ignore it, however, and the outcome is predictable. An exposed outer surface keeps collecting bacteria, the defect deepens, support erodes, and the implant eventually loosens. The difference between a repairable defect and a lost implant is usually time, which is why we treat outside-wall bone loss as a now problem rather than a watch-it problem. It is one of three distinct failure patterns we see; this article covers the outside-wall case specifically, and the overview of failing implant repair options maps the full landscape.

How We Rebuild the Outside Wall

The repair follows a strict sequence, because each step only works if the previous one was honest.

First, the implant surface is detoxified: every trace of bacterial biofilm and debris is removed from the exposed titanium (Fig. 1 shows a typical starting point). Bone will not regenerate against a contaminated surface, so this step decides whether everything after it succeeds.

Next, bone graft material enhanced with biological growth factors is placed against the cleaned surface and covered with a protective membrane that holds the graft in place and encourages new bone formation (Fig. 2). In the case shown, 4 mm of new bone was regenerated to shield the implant, converting an exposed, failing surface back into a supported one.

Throughout healing, a custom temporary bridge seats over the site (Fig. 3), so aesthetics and chewing carry on uninterrupted. No removable denture, no visible gap, no waiting room smile.

Why This Geometry Favors Repair

Salvage decisions always come down to geometry: where the bone was lost, how much remains, and whether the implant is still rigidly anchored. An outside-wall defect leaves the implant stable and creates a contained space that a graft can predictably fill. Contrast that with bone loss encircling the implant on multiple surfaces, which demands a more involved rebuild, or damage from improperly performed implant surgery, where the site often must be reconstructed before a new implant can be placed at all.

The lesson across all three: the earlier the pattern is diagnosed, the more conservative the fix.

Get the Defect Measured Before It Grows

If your gums around an implant are receding, bleeding, or showing a gray shadow of metal through thinning tissue, those are outside-wall warning signs worth taking seriously. Dr. Gerald Marlin, a specialty-trained prosthodontist with more than 3,900 implants placed and restored, evaluates failing implants with 3D imaging and will tell you plainly whether yours can be repaired and what it will take.
