Common All-on-4 Problems
- Temporary prosthesis issues - Temporary teeth worn during healing can chip, crack, or come loose. This is the most common complaint and is easily fixed with a repair visit. At Fusion, our in-house lab can repair or replace temporaries quickly.
- Implant failure - 1-5% of implants may not integrate. If one of the four fails, it's typically replaced, and the prosthesis is adjusted to work with three implants temporarily or a new implant is placed after healing.
- Infection - Post-surgical infection occurs in 2-5% of cases. Treated with antibiotics and, if needed, surgical cleaning. Most infections are resolved without losing implants.
- Bite problems - The prosthesis may need bite adjustments after placement. This is normal and addressed during follow-up visits.
- Speech changes - Some patients experience minor speech changes initially (slight lisp) as they adjust to the prosthesis. This resolves within 1-2 weeks.
- Numbness - Temporary numbness in the lower lip or chin (<1% of cases) usually resolves within weeks as swelling decreases.
How to Minimize Problems
- Choose an experienced specialist - Board-certified oral surgeons with extensive All-on-4 experience have lower complication rates. Fusion has performed more full-arch cases than any other single-owned practice in California.
- Follow post-op instructions - Soft diet, no smoking, proper oral hygiene, and attending follow-up appointments.
- Choose quality materials - Monolithic zirconia prosthetics are far less prone to breakage than acrylic. Fusion's lifetime warranty covers structural failures.
- In-house lab advantage - Problems are resolved faster when the lab is on-site. No waiting weeks for outside lab repairs.
When Problems Happen Elsewhere
Fusion regularly helps patients who've had All-on-4 problems at other practices. Common scenarios:
- Acrylic prosthetics that break repeatedly - we upgrade to monolithic zirconia
- Failed implants at other offices - our surgeons assess and plan revision treatment
- Poor-fitting prosthetics - our in-house lab refabricates for proper fit
- Complications from general dentists - specialist evaluation and correction
If you're experiencing problems with All-on-4 done elsewhere, schedule a consultation. We can usually help.
