If you are in Lincoln and facing the prospect of losing all your upper or lower teeth — or you already wear a denture and are tired of the slipping, the adhesives, and the foods you can no longer eat — All-on-4 dental implants may be the fixed solution you have been looking for. But it is not right for everyone. This guide walks through exactly who qualifies, what disqualifies, and how candidacy is determined, so you can decide whether to take the next step.
A Quick Refresher: What All-on-4 Is
All-on-4 is a full-arch tooth replacement: four dental implants support an entire fixed bridge of teeth for one arch (upper or lower). The two rear implants are placed at an angle, which lets them anchor in available bone — often eliminating the need for bone grafting. In many cases, a fixed temporary bridge is attached on surgery day, so you leave with teeth while healing completes over the following months. Details of the treatment itself are on our All-on-4 page.
Signs You May Be a Strong Candidate
You are likely a good fit for All-on-4 dental implants in Lincoln if several of these describe you:
- Most or all teeth in an arch are failing — advanced gum disease, widespread decay, or multiple failing root canals and crowns
- You already wear a full denture and want a fixed alternative
- Your denture no longer fits well despite relines — a sign of ongoing bone shrinkage
- You avoid foods you love because chewing is difficult or painful
- You are embarrassed by your smile or by teeth that shift when you talk
- You want to avoid extensive bone grafting — All-on-4’s angled design was created for limited-bone cases
- You are in reasonably good general health and can undergo a planned surgical procedure
Many Lincoln patients arrive after years of patching failing teeth with one repair after another. If your dental spending feels like pouring money into teeth with no future, a candid conversation about full-arch replacement can be clarifying — sometimes starting over is the more predictable path.
Factors That Can Disqualify — or Require Extra Steps
Honest candidacy screening also covers the other side:
- Uncontrolled diabetes or immune disorders impair healing and raise failure risk; these need to be managed first
- Heavy smoking significantly lowers implant success — most surgeons require quitting or a serious reduction before and after surgery
- Severe bone loss beyond even angled implants’ reach — uncommon, but in extreme cases grafting or alternative approaches (like more implants or zygomatic options, discussed honestly at consultation) may be needed
- Untreated active gum infection must be resolved before implant surgery
- Certain medications, such as some bone-density drugs, require coordination with your physician
- Uncontrolled teeth grinding (bruxism) does not disqualify you, but the final bridge must be designed to handle the forces — a prosthodontist plans for this
None of these are automatic “no”s except in extreme cases. They are the reason candidacy is determined by examination and imaging, not by a questionnaire.
How Candidacy Is Actually Determined
At Expert Dental Group in nearby Roseville, the candidacy workup includes:
- A comprehensive exam of your remaining teeth, gums, bite, and jaw function
- A 3D CBCT scan (done in-house) mapping bone volume, nerve and sinus positions in three dimensions — this is the decisive tool
- A medical history review covering conditions and medications that affect healing
- A frank discussion of your goals, expectations, and alternatives — including what happens if you choose dentures or do nothing
You leave with a clear yes, no, or “yes, after we handle X” — plus written cost factors for your specific case. The consultation is free: (916) 888-1646.
Why the Specialist Matters for Candidacy Decisions
All-on-4 candidacy is not just “do you have bone.” It involves judging implant angles in 3D, predicting how biting forces will distribute across four implants, designing a bridge that looks natural for your face, and knowing when a case needs a modified approach. Dr. Leila Nikpour is a prosthodontist — the specialist trained in full-mouth rehabilitation — with more than 2,500 dental implants placed and a one-year implantology fellowship in France.

What If You Are Not a Candidate?
It happens, and a good practice tells you plainly. Alternatives include:
- Implant-supported dentures (fewer implants, removable but far more stable than conventional dentures)
- Traditional dentures, sometimes as an interim step while health issues are addressed
- Staged treatment — addressing gum disease or medical issues first, then re-evaluating
A “not yet” is not a “never.” Many patients become candidates after a period of preparation.
The Lincoln-to-Roseville Trip: Worth It?
All-on-4 treatment is a defined series of visits: consultation, surgery day, healing check-ins, and final bridge delivery. Lincoln patients routinely make the short drive to our Roseville office at 5070 Foothills Blvd, Suite 2 for this level of specialty care — the number of visits is small, and the result lasts decades.
Frequently Asked Questions
What is the minimum bone needed for All-on-4?
There is no single number — it depends on bone location and quality, which is why the 3D scan decides. The angled rear implants let All-on-4 work with less bone than older techniques required.
I have severe gum disease. Does that rule me out?
Not necessarily. The diseased teeth are typically removed as part of All-on-4 treatment, and the infection is treated before or during the process. Active infection must be controlled first, which your consultation will plan for.
I’m in my 70s. Am I too old for All-on-4?
Age alone is not a barrier. What matters is your general health and ability to heal. Many All-on-4 patients are in their 60s, 70s, and beyond.
Do I have to quit smoking to get All-on-4?
You will very likely be asked to quit or drastically cut back before and after surgery. Smoking is one of the strongest predictors of implant failure, and no honest practice will skip this conversation.
How do I know if my denture problems mean I should switch to All-on-4?
If your denture needs frequent relines, slips despite adhesive, limits your diet, or you simply hate wearing it, those are strong signals. A consultation can show you exactly what the fixed alternative would involve.
