If you have been living with failing teeth, a mouthful of old crowns and root canals that keep breaking down, or a lower denture that will not stay put, you have probably run across the term All-on-4. It gets used a lot in dental marketing, and it is not always clear what it actually involves or whether you would qualify. Here is a plain explanation of how the treatment works, who tends to be a good fit, and what the process looks like from the first consultation to your final set of teeth.
All-on-4 is a way to replace a full arch of teeth, either the upper, the lower, or both, using four dental implants as the foundation. Instead of placing an implant for every missing tooth, your dentist positions four implant posts at strategic angles in the jawbone. The two implants toward the back are tilted, which lets them anchor into denser bone and support more of the arch. A full bridge of new teeth is then secured onto those four posts.
The result is a set of teeth that stays in your mouth. You do not take it out at night, you do not use adhesive, and it does not shift while you are eating. That is the practical difference between All-on-4 and a traditional removable denture, and for most patients it is the whole reason they start looking into it.
Every case is different, but patients who do well with All-on-4 in Lawrence usually recognize themselves in at least a few of these situations:
• You are missing most or all of the teeth in one or both arches.
• Your remaining teeth are failing, and you have been told that saving them individually would mean a long series of crowns, root canals, and extractions.
• You wear a full denture that slips, causes sore spots, or limits what you feel comfortable eating.
• You have advanced gum disease that has loosened your teeth.
• You want a fixed solution and would rather not add more removable appliances to your routine.
Good candidates are also generally in reasonable overall health and are willing to keep up with cleanings and regular checkups afterward. Implants do not get cavities, but the gum and bone around them still need care.
This is one of the most common reasons patients assume implants are off the table, and it is worth revisiting. When teeth have been missing for a while, the jawbone that used to support them gradually shrinks. With traditional implant treatment, that often means bone grafting first and a longer overall timeline.
The angled placement used in All-on-4 was designed specifically to work around that problem. By tilting the rear implants, your dentist can often take advantage of bone that is still dense and available, which means many patients who were told they needed extensive grafting can move forward without it. Whether that applies to you depends on a 3D scan of your jaw, not on a guess, so a consultation and imaging are the only way to know for certain.
Most patients are surprised by how condensed the treatment is compared to what they expected.
• Consultation and imaging. We review your medical and dental history, examine what is left of your teeth and gums, and take a 3D scan to map bone volume and the position of nerves and sinuses.
• Planning. Your implant positions are planned in advance based on that scan, along with the design of your new teeth.
• Surgery day. Any remaining teeth that need to come out are removed, the four implants are placed, and a temporary set of fixed teeth is attached. You leave with teeth in place, not with an empty arch.
• Healing. Over the next several months, the implants fuse with your jawbone. You eat a softer diet during this stretch while everything integrates.
• Final restoration. Once healing is complete, your temporary bridge is replaced with your final, permanent set of teeth.
Dental anxiety keeps a lot of people from ever picking up the phone about implants. Our practice is home to the Kansas Center for Sedation Dentistry, and sedation options are available for patients who want to be comfortable and relaxed through treatment. If fear has been the thing holding you back, say so at your consultation. It is one of the most common conversations we have.
A conventional denture rests on your gums and relies on suction, shape, and sometimes adhesive to stay in place. It works, and for some patients it is the right choice. But it also covers the roof of the mouth in the upper arch, which affects taste, and it does nothing to stop the bone loss that continues underneath it.
Because All-on-4 implants sit in the jawbone, they stimulate that bone the way natural tooth roots do, which helps preserve facial structure over time. Chewing strength is considerably closer to natural teeth, and the upper bridge does not need to cover your palate. Those three differences, stability, bone preservation, and eating comfortably again, are what patients tend to mention most after treatment.
All-on-4 is a bigger investment than a removable denture, and it is fair to want a clear picture before committing. The total depends on how many arches you are treating, whether extractions or other preliminary work are needed, and the materials used in your final bridge. If you want to understand what drives implant pricing in general, our post on the factors that affect dental implant costs breaks it down. We also review insurance benefits and financing options during your consultation so you know your numbers before you decide anything.
The honest answer to whether you are a candidate is that it takes an exam and a scan to say for sure. What we can tell you is that a lot of patients who assumed they had waited too long, lost too much bone, or were too anxious for surgery turn out to have more options than they expected. If you are somewhere in Lawrence, Eudora, Baldwin City, or the surrounding area and you have been putting this off, a consultation is a low pressure way to find out where you actually stand.
