All On 4 Dental Implants in Nashville: An Overview
All on 4 is a full arch tooth replacement that uses four dental implants to hold a fixed bridge of new teeth. This guide explains how it works and who it helps.
This page is for people in and around Nashville who have lost most or all of their teeth in one or both jaws. It covers the implant procedure, what to expect, cost factors, and when to see a specialist. People who wear removable dentures and want a more stable option may find it useful too.
All on 4 dental implants in Nashville replace a full arch with a set of teeth that stay fixed in place. Unlike removable dentures, you do not take these teeth out at night. The result can feel and function much closer to natural teeth.[1]
How All On 4 Dental Implants Work
The 4 dental implants method places four titanium posts in the jaw to support a full arch of teeth. This design spreads chewing force across the whole jaw.
Dental implants are small titanium posts that act like artificial tooth roots. A surgeon places them in the jawbone, where they slowly fuse to the bone in a process called osseointegration. Once healed, dental implants provide a strong base for replacement teeth.[2]
Research on the all on 4 approach is generally encouraging. A systematic review of clinical studies reported high implant survival rates, often above 95 percent over several years of follow up.[4] An early study that helped introduce the all on 4 concept followed a group of 44 patients treated in the lower jaw and reported implant survival of about 97 percent.[5] These results are promising, but implants can still fail in some patients, and longer term evidence is still growing.
Why Only 4 Dental Implants?
Traditional methods sometimes use six to eight implants per arch. The 4 dental implants approach uses fewer posts and places the two back implants at an angle.
Angling the back implants lets the surgeon anchor them in denser bone near the front of the jaw. This is why all on 4 can often avoid the bone grafting that many other implant teeth plans require. Using four dental implants instead of one per tooth also lowers the total number of surgical sites.
Implant Teeth vs. Removable Dentures
Removable dentures rest on the gums and can shift while you eat or speak. Implant teeth attach to dental implants in the jaw, so they stay fixed.
Both options replace missing teeth, and both have trade-offs. The list below compares them side by side so you can weigh what matters most to you. Your prosthodontist can compare both fairly based on your oral health and bone loss.
- Cost: Removable dentures usually cost less up front. Full arch implant teeth cost more but can last many years with good care.
- Stability: Dentures can move while you eat or talk. Implant teeth stay fixed in the jaw, and many patients report better chewing.
- Surgery: Dentures need no surgery. Implant teeth require an implant procedure and a healing period.
- Daily care: You take dentures out to clean them. You care for fixed implant teeth much like natural teeth, with brushing and regular checkups.
- Bone health: Dentures do not stop the slow bone loss that follows tooth loss. Implants can help keep the jawbone stimulated.
What to Know Before Treatment
Before any dental implant procedure, your provider checks your bone density, gum health, and overall health. These factors decide whether all on 4 is a safe choice for you.
There is no strict age limit for dental implants. Most patients are adults whose jaws have finished growing. A good candidate has enough healthy bone to hold the implants, controlled gum disease, and habits that support healing.[1]
Smoking, uncontrolled diabetes, and heavy bone loss can affect how well dental implants heal. They do not always rule out treatment, but they may change the plan. In some cases a small amount of bone grafting is still needed before implant placement, even with the all on 4 design.
It also helps to know the risks. Like any surgery, implant placement can involve infection, swelling, or slow healing. Over the long term, gum and bone problems around an implant, sometimes called peri-implantitis, can lead to implant failure. Good daily cleaning, not smoking, and regular dental visits lower these risks.[2]
What to Expect During the Implant Procedure
The full arch implant procedure usually happens in stages over several months. You start with imaging and planning, then move to surgery and healing.
Most plans for dental implants in Nashville follow a similar path. Knowing the steps can make the process feel less stressful.
- Consultation and imaging: The provider takes 3D scans to map your bone and plan implant placement.
- Implant surgery: The surgeon places the 4 dental implants and often attaches a temporary set of teeth the same day.
- Healing phase: Over a few months the implants fuse to the bone, while you wear the temporary new teeth.
- Final teeth: Once healing is complete, the provider attaches your final teeth, custom made to fit your bite and face.
From Temporary to Final Teeth
On surgery day, many patients leave with a fixed temporary bridge. This lets you eat soft foods and smile while the implants heal.
After osseointegration finishes, the dental implant surgery results are stable enough to support permanent prosthetic teeth. Your provider removes the temporary set and attaches the final teeth. These new implant teeth are stronger and shaped for long term daily use. Results vary, and the timeline depends on how your bone heals.
Here is one general example of how this can look. A patient who has worn loose lower dentures for years might receive four implants and a fixed temporary bridge in a single visit, eat soft foods over the following weeks, and return a few months later for the final teeth once the bone has healed. This is only an illustration, and your own plan and timeline may differ.
Cost and Financing Options
Full arch dental implants are a larger investment than removable dentures. The price depends on your case and the materials used.
Costs vary by location, provider, and case complexity. Commonly cited ranges for all on 4 run from roughly $12,000 to $30,000 or more per arch, and your quote may land outside that band.[3] Always ask for a written estimate before you agree to treatment.
Many dental offices offer financing options such as monthly payment plans or third party lending. Dental insurance often covers only part of an implant procedure, since some plans treat full arch implants as elective. Check your benefits and ask the office to verify coverage. The word affordable means different things to different people, so compare total costs and financing options across providers.
When to See a Specialist
See a specialist when you are missing most of your teeth, have significant bone loss, or want a fixed full arch instead of removable dentures. Complex cases benefit from focused training.
Here is the key difference in training. A general dentist handles routine care like fillings, cleanings, and simple tooth replacement. A prosthodontist is a dental specialist who completes about three extra years of training focused on replacing missing teeth and restoring the bite. Full arch dental implants are more involved than routine care, which is why many of these cases are led by a prosthodontist who can plan both the surgery and the final teeth.[1]
If you have failing teeth, long term denture problems, or questions about whether the 4 dental implants approach fits your jaw, ask for a specialist consultation. You can learn more about this field on the prosthodontics page. A specialist can also coordinate any bone grafting and the surgical and restorative parts of your care.
- You are missing most or all of your teeth in one or both jaws.
- You have significant bone loss or have been told you may need bone grafting.
- You have failing teeth that may need to be removed.
- You have long term problems with loose or uncomfortable dentures.
- You want a fixed full arch that you do not remove at night.
