All-On-4 dental implants for full mouth restoration
With dental implants, our team at the Oral & Facial Surgery Institute of Houston (OFSIH) can meet all kinds of needs when it comes to replacing missing teeth, including issues related to bone density.
One of the biggest factors in the success of dental implant treatment, whether we are replacing one tooth or an entire arch, is your jawbone. Without sufficient bone mass, implants are more likely to fail. Typically, this would mean that a bone graft would be necessary to make implants possible.
At OFSIH, Dr. L.T. Johnson – an oral and maxillofacial surgeon certified by the American Board of Oral and Maxillofacial Surgery – offers an alternative option for replacing a full arch of teeth without first requiring a bone graft. This solution is known as the All-on-4 treatment concept.
What Is All-on-4?
All-on-4 is a full-arch tooth replacement approach that uses four dental implants placed in strategic positions to support a fixed set of replacement teeth. The back implants are often angled to help maximize existing bone and may reduce the need for grafting in some patients. A personalized exam and imaging are still essential to determine what is appropriate for your anatomy.
Who Is a Candidate for All-on-4?
You may be a candidate for All-on-4 if you are missing most or all teeth in an arch, have teeth that are not restorable, or have difficulty wearing a conventional denture. Candidacy depends on factors such as overall health, gum health, bite forces, and the amount and quality of jawbone. If you smoke or have certain medical conditions, healing and implant success can be affected. We will review your history and imaging before recommending surgery.
What to Expect During the All-on-4 Process
- Consultation and imaging: A clinical exam plus X-rays or 3D imaging (CBCT) to evaluate bone, nerves, and sinus anatomy.
- Treatment planning: We review tooth removal needs, anesthesia options, and the type of restoration planned.
- Surgery day: Any needed extractions are performed, implants are placed, and a temporary restoration may be delivered when appropriate.
- Healing and follow-ups: Your jawbone heals while the implants integrate. We monitor healing and adjust the temporary teeth as needed.
- Final restoration: Once healing is complete, the final fixed teeth are delivered and your bite is refined.
All-on-4 Recovery Timeline
Recovery varies by patient and by the number of teeth removed, bone quality, and medical history. Many people experience swelling and soreness for several days. You will typically be asked to follow a soft diet during early healing and to keep all follow-up visits so we can monitor tissues and bite. Your surgical team will provide personalized instructions based on your procedure.
Important: If you develop worsening pain, fever, increasing swelling, drainage, or difficulty swallowing or breathing, contact our office right away.
What is the Difference Between an All-on-4 and a Regular Implant Supported Denture?
When considering implants for replacing a full arch of teeth, one of the first options discussed is typically an implant-supported denture. This treatment uses anywhere from 6 to 8 dental implant posts inserted into your jawbone to secure the full arch of replacement teeth in your mouth.
In cases where the bone is not strong enough to support the required number of implant posts, you may be presented with a solution called All-on-4. This is still a full-arch dental implant solution. The biggest difference, however, is that All-on-4 only uses four posts. The positioning of the posts is crucial for this treatment. While the front posts are placed straight up and down in the bone, the back implants are placed at a 45-degree angle.
Do I Have Other Options?
The All-on-4 treatment concept is just one option that can be used to replace an entire arch of missing teeth where the bone is not strong enough to hold the posts needed for a regular implant-supported denture.
Another option that can provide you with dental implants without the need for a bone graft is a bar-retained dental implant-supported denture. The biggest difference with this treatment is that your replacement teeth snap into place on a bar instead of being secured with screws. The teeth still need to be removed to be cleaned and to clean your mouth properly.
These are not the only options available. You can have your arch of missing teeth replaced with a traditional denture. You may also choose to have a hybrid option. There is a solution that uses dental implants to secure a conventional denture into place. This type of solution is commonly used in the lower jaw, where a traditional denture has a harder time staying stable.
How Much Does All-on-4 Cost?
The All-on-4 treatment concept typically costs less than a regular implant-supported denture. The final cost will vary from patient to patient and depends on factors like:
- The need for tooth extractions
- The types and number of images and scans taken
- If you need to have any treatments, such as gum disease treatment, before implant surgery
- The number of follow-up appointments you need
For patients who have lost bone mass and cannot support an implant-supported denture, the All-on-4 treatment concept can be an excellent alternative option.
FAQs
Am I a Candidate for All-on-4 Dental Implants?
You may be a candidate if you are missing most or all teeth in an arch, or if remaining teeth are severely damaged and cannot be restored. Candidacy depends on your overall health, gum health, bite forces, and jawbone anatomy, so an exam and imaging are required.
What Is the Process of Getting All-on-4 Dental Implants?
The process begins with a consultation and imaging to plan implant placement and review anesthesia options. On surgery day, any needed extractions are performed and four implants are placed per arch. A temporary restoration may be delivered when appropriate, followed by a healing period and then the final fixed teeth.
How Long Does the All-on-4 Dental Implant Procedure Take?
Surgery time varies based on your needs and whether extractions are required. Many cases are completed in one visit, but the overall treatment timeline includes healing and follow-up visits before the final restoration is delivered.
How Do I Care for My All-on-4 Dental Implants?
Brush as directed, clean under the bridge (often with floss threaders or a water flosser), and keep routine professional checkups. Avoid tobacco and follow any dietary instructions during early healing. Your team will provide a home-care plan based on your restoration type.
How Do All-on-4 Dental Implants Improve Speech and Chewing Ability?
Because All-on-4 teeth are anchored to implants, they are designed to be more stable than a traditional removable denture. Many patients notice improved confidence with speech and the ability to chew a wider variety of foods once cleared by their surgeon.
What Type of Material Is Used for the Prosthetic Teeth in an All-on-4 Treatment?
Restorations may be made from materials such as acrylic (PMMA), composite, porcelain, or zirconia. The best option depends on your bite, goals, and budget, and we will review material choices during treatment planning.
How Soon After the Procedure Can I Eat Normally?
Most patients start with soft foods and advance their diet gradually. Your surgeon will give specific guidance based on healing progress and the type of restoration placed. Avoid hard or sticky foods until you are cleared to reduce stress on the implants and temporary teeth.
What Are the Most Common Complications Associated With All-on-4 Implants?
As with any surgery, risks can include swelling, bleeding, infection, and implant integration problems. Some patients may also need bite adjustments or repairs to temporary teeth. Careful planning, good home care, and follow-up visits help reduce risk.
