All-on-4 is a full arch implant technique that uses just four strategically placed titanium posts to support an entire set of fixed replacement teeth. Two implants are placed vertically at the front of the jaw and two are angled at the back, maximizing contact with available bone and often eliminating the need for bone grafting.
One of the biggest advantages of All-on-4 is speed. In many cases, a temporary set of teeth can be attached the same day as surgery, so you walk out of the office with a complete, functional smile. Once healing is complete, your permanent prosthesis is placed for a result that’s built to last.
The All-on-4 technique places four titanium implant posts into the jawbone at precise positions and angles. The two back implants are tilted to engage deeper, denser areas of bone, which provides maximum stability using minimal hardware. This angled placement is what often allows patients with moderate bone loss to receive implants without grafting.
Once the posts are placed, a temporary prosthetic arch is attached the same day. Over the next several months, the implants fuse with the bone through osseointegration. After healing is complete, your permanent custom arch is fabricated and attached for a final result that looks, feels, and functions like natural teeth.
Traditional dentures rest on the gums and rely on suction or adhesive to stay in place. They can slip during meals, irritate soft tissue, and accelerate bone loss over time because they don’t stimulate the jaw.
All-on-4 implants are fixed directly to the bone. They don’t move, they don’t require adhesive, and they preserve your jawbone by mimicking the stimulation of natural tooth roots. Patients who switch from dentures to All-on-4 consistently describe it as life-changing. It’s a completely different experience.
All-on-4 is ideal for patients who have lost all or most of their teeth in one or both arches and want a permanent, fixed solution with a faster timeline. It’s especially well-suited for patients with moderate bone loss who may not be candidates for traditional implant approaches without extensive grafting.
Current denture wearers looking to upgrade to something permanent are also excellent candidates. Dr. Koman will evaluate your bone structure, gum health, and overall health with 3D imaging to confirm whether All-on-4 is the right fit or if a different implant approach would serve you better.
These transformations were performed right here at Koman Dental Denver. Every case is unique, but the results speak for themselves.
Full mouth rehabilitation combining implants and restorations for lasting function and confidence.
Veneers and whitening designed to enhance natural beauty while maintaining a seamless, authentic look.
A full arch of permanent teeth placed on four implants, replacing failing dentition with a complete, functional smile.
Dr. Koman takes comprehensive 3D imaging to evaluate your jawbone and digitally plans the position and angle of each implant for maximum stability.
Four implant posts are surgically placed under anesthesia. In most cases, a temporary prosthetic arch is attached the same day so you leave with a full set of functional teeth.
Over the next several months, the implants fuse with your jawbone. You'll wear your temporary teeth comfortably throughout this period while the foundation solidifies.
Once healing is complete, your final custom arch is fabricated and permanently attached. Fit, color, and bite are all verified. The result is a set of permanent teeth built to last.
All-on-4 uses exactly four angled implants to support a full arch, often allowing same-day teeth and avoiding bone grafting. Full arch implants may use more posts for additional support depending on your bone structure. Dr. Koman will recommend the approach that fits your situation best.
One of the main advantages of All-on-4 is that the angled rear implants engage denser areas of bone, which often eliminates the need for grafting. Dr. Koman will confirm whether your bone is sufficient during your 3D imaging consultation.
In most cases, yes. A temporary prosthesis is fabricated and attached to the implants on the day of surgery. These temporary teeth are functional and natural-looking while your permanent arch is being made.
You'll receive temporary teeth the day of surgery. The full process from placement to permanent prosthesis typically takes 4 to 6 months, with the majority of that time dedicated to healing.
Absolutely. Many All-on-4 patients are former denture wearers looking for a permanent upgrade. Dr. Koman will evaluate your bone and gum health to determine if you're a candidate or if any prep work is needed first.
