How Long Do Dental Implants Last?

Published peer-reviewed studies place 10-year implant survival between 95% and 98% depending on the patient population. Twenty-year survival in well-controlled cohorts is around 93%. Cases at the 30-year mark from the original Brånemark group still show 80%+ original-implant survival.

The implant body itself — the titanium screw in the bone — routinely lasts 25+ years. The crown on top may need replacement at 15–20 years if it wears, chips, or simply stops matching the surrounding teeth. At our practice, the zirconia crown carries a lifetime warranty against fracture or wear.

Hygiene. Far and away the biggest predictor. Patients who keep up with twice-yearly cleanings and brush around the implant the way we teach them see 30-year survival in the high 90s. Patients who skip hygiene visits are the ones who lose implants to peri-implantitis at year 10–15.

Surgical planning. An implant placed at the correct angle, depth, and in healthy bone essentially never fails for mechanical reasons. The 2–5% of failures happen almost entirely in cases with insufficient bone, untreated infection, or compromised placement angles. CT planning and surgical guides have driven failure rates down significantly over the past decade.

Not smoking. Smokers have roughly double the failure rate, both early (failed integration) and late (peri-implantitis). Quitting around surgery and staying off is one of the highest- leverage decisions you can make.

Age.A healthy 80-year-old's implant outlasts a sedentary 50-year-old's. Bone responds to mechanical loading at any age; what matters is overall medical health and hygiene.

Brand of implant. The major implant systems (Nobel Biocare, Straumann, BioHorizons, Zimmer) all have comparable long-term survival data. We use Nobel and Straumann because of their published 30-year studies, not because they are mechanically superior to other quality systems.

How the implant feels.Once integrated, an implant has no feedback. You will not feel it failing the way you might feel a tooth becoming sensitive. This is why annual radiographic follow-up matters — we catch peri-implant bone loss on imaging before you'd ever notice symptoms.

Peri-implantitis. Gum inflammation around the implant that progresses to bone loss. Caused by plaque buildup at the implant-gum junction. Prevented almost entirely by proper hygiene and regular cleanings. Treatable in early stages, often unrecoverable late.

Mechanical overload. Grinding (bruxism), clenching, or biting on something extremely hard can crack the abutment screw or the crown. Easily fixed by replacing those parts; the implant itself usually survives. We provide a night guard at no extra cost for patients with confirmed grinding.

Medication changes. Starting IV bisphosphonates (for cancer treatment) or immunosuppressives years after implant placement can occasionally trigger late failure. Coordinate with your medical team if these are prescribed.

At 5D Smiles, the zirconia crown carries a lifetime warranty against fracture or wear when seen at your twice-yearly hygiene visits. The titanium implant body carries a 3-year warranty against integration failure. Replacement of a failed implant is at-cost (lab and parts only), not a re-charge of the full fee.

We see implant patients twice yearly for hygiene and once yearly for radiographs. The visit takes 45 minutes. Catching early bone loss on imaging is the single best way to keep an implant for 30+ years.
