All-on-4 dental implants have a remarkably high success rate — typically between 94% and 98%. Failures are uncommon and usually occur during the initial healing (osseointegration) phase or later due to chronic issues. The primary risk factors that increase failure rates include uncontrolled systemic conditions like diabetes, heavy smoking, poor oral hygiene leading to peri-implantitis, and severe teeth grinding without a protective night guard. Dr. Davis screens for these factors during consultation to maximize your long-term outcome.

All-on-4 is considered the gold standard for full-arch restoration for most patients — but alternatives may suit specific clinical needs. All-on-6 or All-on-8 uses more implants for patients with heavy bite forces or exceptional bone density. Traditional individual implants replacing every missing tooth provide the most independent, natural feel but require massive bone volume and multiple surgeries at significantly higher cost. Removable implant overdentures snap onto 2–4 implants for improved stability compared to traditional dentures, but can still be taken out at night.

Potential complications, though uncommon, include implant failure (roughly 5% of cases — when titanium posts don't properly fuse with bone due to poor bone quality, smoking, or medical conditions); peri-implantitis (chronic gum inflammation from inadequate hygiene); mechanical damage such as chipping or wear of the prosthetic teeth; and rare surgical complications like nerve irritation or sinus issues for upper-jaw implants. Careful patient selection, proper technique, and diligent hygiene minimize all of these risks significantly.

At the 2-month mark, you're typically deep into the osseointegration healing phase where your jawbone is actively fusing around the titanium posts. Initial surgical swelling and tenderness will have fully resolved by then. You'll still need to follow a soft-to-medium food diet to protect the healing implants from premature pressure. Dr. Davis will monitor your progress with periodic check-ins to confirm the implants are integrating properly and to prepare for the eventual placement of your final permanent prosthesis.

Initially yes — but only during the healing phase. Right after surgery, you must stick to a strict soft-food diet for several months to protect the implants while they fuse with the bone. Once healing is complete and your final permanent bridge is placed, eating becomes remarkably easy and natural. Unlike traditional dentures that limit your diet, All-on-4 restores near-full bite force, allowing you to comfortably chew crunchy, tough, and fibrous foods again — including apples, steak, corn on the cob, and other foods denture wearers typically avoid.

The titanium implant posts themselves can last 20 years to a lifetime once successfully integrated with the jawbone — they're structurally permanent components. However, the attached prosthetic bridge experiences daily mechanical wear and typically requires repair, refurbishment, or full replacement every 10 to 15 years depending on the material used (acrylic wears faster than zirconia). Consistent daily hygiene, avoiding tobacco, wearing a night guard for bruxism, and routine six-month check-ups all directly extend longevity.
