All-on-4 Can Replace Multiple Missing Teeth

Losing most or all of the teeth in an arch can affect more than your smile—it changes how you eat, speak, and feel about yourself. At Alameda Dental in Aurora, CO, we meet many patients who are exploring fixed, long-term solutions for multiple missing teeth. One option that often comes up in these conversations is All-on-4, a technique that uses four dental implants to support a full arch of replacement teeth. Instead of placing a separate implant for every missing tooth, the All-on-4 approach strategically positions four implants in the jaw so they can hold an entire set of fixed teeth. This tends to be less invasive than traditional full-arch implant methods and can often be completed without the need for extensive bone grafting. The result is a stable, natural-looking restoration that stays in place—no adhesives, no slipping, and no nightly removal required.

01 / How All-on-4 WorksHow All-on-4 Works

Traditional dentures rest on the gums and rely on suction or paste for grip. Over time, the jawbone beneath a removable denture can shrink because it no longer receives the stimulation that natural tooth roots once provided. This bone loss gradually leads to a loose fit, discomfort, and reduced chewing ability. Individual dental implants are excellent for replacing single teeth or small gaps, but when an entire upper or lower arch is missing, placing eight or more individual implants may be more involved and often requires significant bone grafting. All-on-4 bridges these concerns. By using only four implants per arch, with the two back implants angled to maximize contact with available bone, the technique often works with the bone a patient already has—even if some bone loss has occurred.

The implants are typically made of titanium, a biocompatible material that fuses with the jawbone over time. Once healed, they serve as anchor points for a full-arch prosthesis that is custom-designed to match your facial structure and bite. The prosthesis is fixed, meaning only our team can remove it during routine maintenance; you treat it much like natural teeth at home.

02 / Who Might Benefit from All-on-4?Who Might Benefit from All-on-4?

All-on-4 is intended for adults who are missing all or most teeth in an arch. It can also be a next step for individuals who currently wear dentures but are frustrated by looseness, sore spots, or dietary limitations.

Candidacy depends on several factors, including overall health, jawbone volume, and gum condition. During a consultation, our team reviews your medical history and takes imaging to map the bone and identify key anatomical landmarks. Conditions such as uncontrolled diabetes, active gum disease, a history of radiation to the jaw, or heavy smoking can affect healing and implant success. These do not automatically rule out treatment, but they mean we need to carefully address them before moving forward.

03 / What to Expect During the All-on-4 ProcessWhat to Expect During the All-on-4 Process

Initial Consultation

Your journey begins with a conversation. We listen to your goals and concerns, examine your mouth, and capture diagnostic images. If you have remaining teeth that need to be removed, we discuss the timing and any preparatory steps. We then outline a personalized plan, including estimated timeframes and what each stage involves.

Preparing the Jaw

If teeth are present in the arch, they are extracted. In many cases, we can place the implants during the same visit as the extractions—this allows us to move efficiently toward the final result. Sometimes a minor bone graft is needed to create a solid foundation for the implants. If grafting is required, additional healing time is factored into the plan.

Implant Placement and Healing

The four implants are placed in predetermined positions: two near the front of the jaw and two angled toward the back. The surgery is performed under appropriate anesthesia so you remain comfortable. After the implants are in place, a temporary fixed prosthesis is often attached right away, so you leave with functional teeth while the implants heal. The healing period typically lasts several months, during which the implants fuse with the bone. You will be asked to follow a soft diet and keep the area clean.

Receiving Your Final Teeth

Once the implants are solidly integrated, new impressions are taken to create the final prosthesis. The permanent bridge is designed for durability, natural aesthetics, and a comfortable bite. It is then secured to the implants. From this point on, you can enjoy a wide range of foods and smile without hesitation.

Daily Care

Caring for a fixed full-arch restoration is straightforward. Brush twice daily with a soft-bristle toothbrush, paying attention to the area where the prosthesis meets the gums. We often recommend a water flosser or specialized interdental brushes to clean beneath the bridge. Regular dental visits allow us to monitor the implants and surrounding tissues.

Follow-Up Visits

After your final teeth are placed, periodic checkups are important. These visits give us a chance to examine the hardware, assess your bite, and professionally clean areas that are hard to reach at home. With consistent care, the implants can remain stable for many years. The prosthesis may eventually need refurbishment or replacement due to normal wear, but the underlying implants are designed for longevity.

02 / Common Questions About All-on-4Common Questions About All-on-4

Will I be without teeth during the healing phase? No. A temporary bridge is usually fixed to the implants at the time of surgery, so you will have teeth throughout the healing period. You will need to eat soft foods while the bone bonds to the implants.

Is the procedure painful? Anesthesia is used during surgery to keep you comfortable. Afterward, any mild soreness is generally managed with over-the-counter pain relievers and should subside within a few days.

How long does the entire process take? From start to finish, the timeline varies. Healing after implant placement often takes a few months, and the final prosthesis is delivered once healing is confirmed. If extractions or grafting are part of your plan, the overall timeline may be extended.

Can I upgrade from my current dentures to All-on-4? Yes. Many of our patients transition from traditional dentures to a fixed implant-supported bridge. We carefully plan the switch so you never have to go without teeth.

What if an implant doesn’t integrate? Implant integration is highly predictable, but if an implant fails to fuse, options exist. Often a replacement implant can be added without disrupting the other three or the temporary bridge.

Will my dental plan contribute? Benefits vary widely by carrier and plan. We can submit a pre-treatment estimate to your insurance to give you a clearer picture of any reimbursement. We also discuss financial arrangements to help fit treatment into your budget.

How do I clean under the bridge? We will show you techniques—usually a water flosser and a thin interdental brush—that make daily maintenance quick and effective.
