All-on-4 technology refers to placing four strategically planned implants to keep a denture in place. This prevents the need for more than just four implants to be used and all of the implants can be placed in one or two appointments. The procedure helps your denture to fit more securely and prevents the need for creams, adhesive strips and gels. The procedure is safe, easy and most implants heal fully in about six months.

Why would All-on-4 be needed?

You may want or even need All-on-4 if your current prosthesis is constantly slipping and falling out. Likewise, your prosthetic appliance might be uncomfortable or ill-fitting, causing you to feel pain or discomfort whenever you put it in. The implants easily keep the denture in place so that it won't slip or budge. This allows for a more natural and realistic-looking smile.

Who's a good candidate for All-on-4?

The majority of patients who want All-on-4 can safely have the procedure done. Keep in mind that implants rely on healthy underlying bone mass to bond fully. If you have bone loss, we may suggest a bone grafting before the surgery can be done. We will go over your patient history before placing implants and you should be healthy enough to undergo the procedure and heal from it.

All-on-4 Dental Implant FAQs

What is All-on-4 and how is it different from traditional dentures?

All-on-4 is a full-arch tooth replacement solution that uses just four dental implants to permanently anchor a full set of teeth to the jawbone. Unlike traditional dentures, which rest on the gums and can slip during eating or speaking, All-on-4 teeth are fixed in place 24/7 and function like natural teeth — restoring close to 100% of normal chewing strength. Most patients never take them out.

How long does the All-on-4 procedure take?

The surgical portion of All-on-4 is typically completed in one appointment, during which all four implants are placed and a temporary set of teeth is attached the same day. Full healing — when the implants fully fuse to the jawbone — takes 3 to 6 months, after which the final permanent prosthesis is placed. Most patients leave the surgical appointment with working teeth they can use right away.

Am I a candidate for All-on-4 if I've been told I have bone loss?

Yes — All-on-4 is specifically designed for patients with some degree of bone loss. The four implants are angled strategically to take advantage of the densest available bone, which often eliminates the need for bone grafting that traditional implants would require. For more significant bone loss, we offer bone grafting and ridge augmentation at our Fremont office to build a stable foundation for successful placement.

How much does All-on-4 cost in Fremont, CA?

All-on-4 cost varies significantly based on the prosthesis material chosen, whether one or both arches are being restored, and your insurance coverage. It is a larger investment than traditional dentures, but often more cost-effective over a lifetime because it eliminates ongoing denture replacement, adhesive, and relining costs. Our team will walk through a detailed estimate and financing options at your consultation.

How do I care for my All-on-4 teeth?

All-on-4 teeth are cared for much like natural teeth — daily brushing, flossing (or water flossing) around the base of the prosthesis, and regular professional cleanings. Because the teeth are fixed in place, you don't need to remove them at night or use adhesives. We'll show you exactly how to clean around the implant connections during your follow-up visits at our Fremont office.

Can I have IV sedation during the All-on-4 procedure?

Yes. IV sedation is one of the most popular options for All-on-4 surgery at Mission Peak Dental. You'll be in a deep, comfortable, twilight sleep state for the entire procedure — most patients have no memory of the surgery and report feeling well-rested afterward. IV sedation is particularly recommended for All-on-4 because it allows us to complete the full-arch procedure in a single, longer session rather than splitting it across visits.
