All-on-4®

Return to Our Services

A full arch of fixed teeth on four implants

All-on-4® replaces an entire upper or lower arch of teeth with a single, fixed prosthesis anchored by four strategically placed dental implants. Instead of a removable denture, you get a stable, non-removable restoration that looks and functions much like natural teeth, restoring chewing ability, speech, and facial support. For patients who have struggled with loose dentures or multiple failing teeth, it can be a life-changing improvement in comfort and confidence.

Precision planning with 3D imaging

Every case begins with detailed digital planning. A cone-beam CT (CBCT) scan captures three-dimensional images of the jaws, showing bone volume, density, and the location of nerves and sinuses. From that data, a digital surgical plan maps each implant’s exact position and angle, often making it possible to maximize support in the available bone without complex grafting.

Custom surgical guides are designed and 3D printed in-house, translating the digital plan directly to surgery. Guided placement improves accuracy, reduces chair time, and lets the team simulate the final prosthesis, esthetics, bite, and function, before any treatment begins, so you can see and understand the plan clearly.

Coordinated care from surgery to final teeth

Bone grafting (when needed), implant placement, and the final restoration are all coordinated within one office. That continuity means fewer handoffs, seamless communication, and one clinical team managing every phase, including sedation options and follow-up care.

During the surgical visit, the implants are placed according to the guided plan. Depending on your case, a temporary fixed prosthesis may be attached the same day so you leave with functional, natural-looking teeth while the implants heal. The final restoration is then crafted to match your facial proportions, bite, and cosmetic preferences.

Healing and what to expect

After placement, the implants integrate with the jawbone over the following weeks and months, a process called osseointegration. Most patients follow a staged diet, progressing from softer foods back to normal eating as healing advances. Some swelling or tenderness in the first days is normal and manageable with standard aftercare. Follow-up visits track soft-tissue healing, implant stability, and how the temporary restoration is functioning.

Caring for your new smile

With good maintenance, All-on-4® restorations can provide many years of reliable service. Long-term success comes down to a few habits:

  • Daily cleaning with the techniques and tools your team recommends, such as specialized brushes or water irrigation
  • Routine checkups, hygiene visits, and periodic imaging to catch small changes early
  • Managing risk factors such as smoking or uncontrolled diabetes

Prosthetic parts, screws, attachments, acrylic teeth, can wear over time, and regular evaluations allow them to be refreshed or repaired without disturbing the underlying implants. Implant failure is uncommon, and early detection through follow-up care makes most issues straightforward to manage. A consultation will determine whether All-on-4® fits your oral health, bone quality, and goals.

Frequently Asked Questions

What is All-on-4®?

All-on-4® is a dental implant treatment concept that replaces an entire arch of teeth using four strategically placed implants. This approach supports a full fixed prosthesis that restores chewing function and facial support. The method emphasizes implant placement in denser areas of the jaw to maximize stability.

Patients often receive a provisional set of teeth placed on the same day as implant surgery, allowing immediate function and appearance. After a period of healing and osseointegration, the provisional prosthesis is replaced with a customized permanent restoration. All-on-4® is a licensed treatment concept developed to streamline full-arch rehabilitation for appropriate candidates.
Ideal candidates for All-on-4® include people who are missing most or all teeth in one or both arches or those whose remaining teeth are not salvageable. Sufficient bone in key areas of the jaw is important, though the All-on-4® approach can often avoid more extensive grafting by utilizing angled posterior implants. General health factors such as smoking, uncontrolled diabetes, or certain medications can affect candidacy and should be discussed during evaluation.

A thorough clinical exam, dental imaging such as CBCT, and medical history review are used to determine suitability for the procedure. Your dentist will explain whether provisional same-day teeth are appropriate or if additional preparatory treatments are needed. The final recommendation is individualized and focuses on predictable function, comfort, and long-term success.
The All-on-4® treatment begins with careful planning that includes clinical examination, detailed imaging, and digital or physical impressions. Using this information, the surgical team plans implant positions to maximize support while avoiding critical structures such as nerves and sinuses. On the day of surgery, four implants are placed in the jaw and a provisional prosthesis is attached, providing immediate restoration of appearance and chew function.

Surgical guides or computer-aided workflows may be used to enhance accuracy and predictability. Following implant placement, patients have scheduled follow-ups to monitor healing and make any necessary adjustments to the provisional prosthesis. Once implants have integrated with the bone, the provisional prosthesis is exchanged for a custom-crafted permanent restoration built from more durable materials.
Initial recovery after All-on-4® commonly involves swelling, mild to moderate discomfort, and a short period of dietary modification to protect the surgical sites. Patients receive specific post-operative instructions regarding oral hygiene, medication, and activity to support healing and reduce risk of complications. Pain and swelling typically subside over a few days to a couple of weeks, and adherence to follow-up appointments helps track progress.

Most people can return to light daily activities within a few days and resume normal chewing with their provisional prosthesis as directed by the surgical team. Longer-term healing and osseointegration occur over several months, during which thorough home care and professional monitoring are important. Any concerns such as persistent pain, excessive bleeding, or prosthesis instability should be reported promptly so the team can address them.
Compared with removable dentures, an All-on-4® fixed prosthesis offers greater stability because the restoration is anchored to implants rather than relying on soft-tissue support. This anchorage improves chewing efficiency and reduces common denture-related issues such as slipping and sore spots. Implant-supported restorations also help preserve jawbone by transmitting functional forces to the bone, which can slow resorption.

Maintenance needs differ from removable dentures; implant-supported prostheses require both home hygiene routines and periodic professional care. Patients should continue to see their dental team for checks and hygiene to monitor implant health and prosthesis condition. Your clinician will explain the specific cleaning techniques and tools that best protect implants and surrounding tissues.
All-on-4® restorations are designed to be long-lasting, but their longevity depends on proper care, regular maintenance, and overall health. Daily cleaning of the prosthesis and attention to soft-tissue health reduce the risk of complications such as peri-implant inflammation. Certain prosthetic materials and design choices influence durability, and your dental team will select options that balance strength and esthetics.

Routine professional evaluations typically include implant stability checks, soft-tissue assessment, and adjustments or repairs to the prosthesis as needed. Imaging may be taken periodically to monitor bone levels around implants and detect issues early. Consistent follow-up care and responsible home hygiene are the most reliable ways to protect your restoration.
As with any surgical procedure, All-on-4® carries potential risks including infection, bleeding, nerve irritation, or sinus complications depending on implant location. Early detection and prompt management of these issues reduce their impact on overall outcomes. Selecting an experienced surgical team and following pre- and post-operative directions helps minimize risk.

Implant failure is an uncommon but possible outcome that may require removal or replacement of the affected implant. Factors such as smoking, uncontrolled systemic conditions, or poor oral hygiene increase the likelihood of complications and should be discussed honestly during planning. Clear communication with your clinician about symptoms and expectations supports timely intervention when needed.
The provisional prosthesis placed on the day of surgery focuses on immediate function, esthetics, and protecting healing tissues while implants integrate. These temporary restorations are typically made from materials suited for short-term use and are adjusted to ensure comfort during the healing phase. Because they are designed for transition, patients may notice differences in feel and durability compared with the final restoration.

The permanent prosthesis is fabricated after healing and is crafted from more durable materials with refined fit, occlusion, and esthetic details. Final restorations are customized to balance strength, ease of maintenance, and a natural appearance that complements facial features. Your clinician will review the timing for transitioning to the permanent prosthesis and explain what to expect during that appointment.
