All-on-X Dental Implants in Newton, MA
Permanent, Fixed Teeth — Placed by a Surgeon and Prosthodontist Working Together
Most people who come to us have been dealing with the problem for longer than they want to admit — a loose denture that shifts when they eat, teeth that have failed one by one over the years, or a mouth that simply no longer functions the way it should. They’ve often been told they need implants, but weren’t sure where to start, or whether it was even possible for them.
All-on-X dental implants offer a permanent solution — a full arch of fixed teeth, supported by as few as four strategically placed implants, delivered in a single surgical appointment. At Newton Dental Associates, this procedure is performed by an oral and maxillofacial surgeon and a board-certified prosthodontist who plan and execute every case together. That level of coordination is not standard. It is what sets our outcomes apart.
Our practice serves patients throughout Newton, Boston, Brookline, Wellesley, Needham, Waltham, and the surrounding Greater Boston area.
Why Patients Choose All-on-X Instead of Dentures
Dentures have improved over the years, but they still carry the same fundamental limitations they always have. They rest on the gum surface, which means they shift. Without tooth roots stimulating the jawbone, the bone continues to resorb — changing the fit of the denture over time and altering the shape of your face. Adhesives become part of daily life. Certain foods stay off the menu permanently.
Full arch implants address the root of the problem. Because the implants are placed directly into the jaw, they function like natural tooth roots — stimulating the bone, stabilizing the prosthesis, and restoring full chewing force. The result is teeth that feel, function, and look like your own.
At a glance, the difference:
- Dentures can slip during meals and conversations. All-on-X teeth are fixed and non-removable.
- Dentures accelerate bone loss. Implants preserve jawbone and facial structure.
- Dentures limit your diet. Implants restore the ability to eat steak, raw vegetables, and everything in between.
- Dentures cover the palate, dulling taste. All-on-X prosthetics are palate-free.
- Dentures require adhesives and nightly removal. All-on-X teeth are brushed and cared for like natural teeth.
What Are All-on-X and All-on-4® Implants?
All-on-4® is a trademarked technique that uses exactly four dental implants to support a full arch of fixed teeth. Two implants are placed vertically at the front of the jaw; two are angled toward the back to maximize contact with available bone. This angulated placement allows many patients with moderate bone loss to receive implants without bone grafting.
All-on-X is the broader term for full arch implant treatment using four, five, or six implants depending on what your anatomy requires. Some patients benefit from additional implants for added stability, greater load distribution, or longer-term durability. We assess each case individually and plan the number and position of implants based on your specific bone structure, bite, and functional demands — not a preset template.
In both cases, the implants serve as anchors for a fixed prosthetic arch — meaning you leave with a full set of teeth that do not come out.
The Newton Dental Associates Difference: One Team, One Plan, One Location
Most dental practices that offer All-on-4 refer the surgical portion to an outside oral surgeon, then hand the patient back to a restorative dentist for the prosthetic work. These two providers often plan their components independently. That gap in communication is where problems tend to emerge — implants placed without the final restoration fully mapped out, or prosthetics designed without accounting for where the surgeon could safely place the fixtures.
At Newton Dental Associates, your surgeon and prosthodontist are in the same building, working from the same treatment plan, from the first consultation through final delivery. There are no referrals and no handoffs between separate offices.
Your full arch case is led by:
- Dr. Ami Amini-Salari — Oral & Maxillofacial Surgeon, responsible for implant placement using guided surgical techniques and 3D-planned angulation
- Dr. Ashley Amini-Sami — Board-Certified Prosthodontist, responsible for designing the prosthetic arch, bite function, and final aesthetics
Because both specialists are involved from day one, implant positioning is determined with the final restoration already designed. This means the bite is optimized before a single implant is placed. It also means your care is continuous — the same two clinicians who planned your case are the ones who finish it.
Teeth in a Day: What the Procedure Actually Looks Like
The phrase “teeth in a day” can sound like a marketing claim. In practice, it is an accurate description of the treatment protocol — and understanding what happens during your procedure day helps set realistic expectations.
On the day of your surgery:
- Any remaining failing teeth are extracted, if applicable.
- Four to six implants are surgically placed into the jawbone using guided technique — a method that follows a digitally planned surgical guide for precise, predictable placement.
- A temporary fixed prosthesis — a full arch of teeth — is attached to the implants before you leave.
- You go home that same day with a functional, natural-looking set of fixed teeth.
Over the following three to six months, the implants fuse with the surrounding bone through a process called osseointegration. Once that healing is complete, Dr. Amini-Sami delivers your final, custom-designed prosthesis — made from high-quality materials selected to match the strength, color, and character of natural teeth.
You are not without teeth at any point in the process.
Who Is a Candidate for All-on-X Dental Implants?
All-on-X is well-suited for adults who have lost most or all of their teeth in one or both arches, or who have teeth that are failing to the point where extraction is the appropriate path forward. Common presentations we see include:
- Patients wearing full or partial dentures who are unhappy with fit, function, or aesthetics
- Patients with multiple teeth affected by advanced decay, fractures, or failed restorations
- Patients with periodontitis (advanced gum disease) that has compromised the supporting bone
- Patients who have been edentulous (toothless) for some time and are experiencing bone loss and facial changes
One of the most common misconceptions we encounter is that bone loss disqualifies a patient from implants. For most patients, this is not the case. The angled implant placement used in All-on-4 and All-on-X is specifically designed to access denser, more available bone at the front and sides of the jaw. Many patients who were told elsewhere that they did not have enough bone have been treated successfully at our practice.
For cases with significant resorption, bone grafting or sinus lift procedures may be recommended before implant placement. We assess this during your consultation using 3D CBCT imaging, which gives us a complete picture of your available bone volume and quality before any treatment planning begins.
The Full Arch Implant Process at Newton Dental Associates
Step 1: Consultation and 3D Imaging
Your first appointment involves a thorough clinical evaluation and a cone-beam CT scan (CBCT) — a 3D image of your jaw and bone structure. This imaging allows us to assess bone volume, identify anatomical landmarks, and begin planning implant position with precision. You will meet with both Dr. Amini-Salari and Dr. Amini-Sami during this visit.
Step 2: Digital Treatment Planning
Using your CBCT data and digital scans, we design the implant placement and the prosthetic restoration simultaneously in a virtual environment. The surgical guide used on procedure day is fabricated from this digital plan. Nothing about your case is improvised.
Step 3: Surgical Placement
Dr. Amini-Salari places the implants using guided surgical technique. Sedation is available — most of our All-on-X patients choose IV sedation for a comfortable, anxiety-free experience. The procedure is performed at our Newton facility.
Step 4: Same-Day Temporary Prosthesis
Before you leave, Dr. Amini-Sami attaches a fixed temporary arch. This provisional prosthesis allows you to eat, speak, and smile while your implants heal. It is adjusted for fit and bite before you go home.
Step 5: Healing and Osseointegration
Over the next three to six months, the implants integrate with your jawbone. During this period, we monitor your healing at scheduled follow-up appointments. Dietary restrictions during early healing are typically limited to soft foods for the first few weeks.
Step 6: Final Restoration Delivery
Once your implants are fully integrated, Dr. Amini-Sami delivers your custom final prosthesis. The final arch is designed for long-term durability, natural aesthetics, and optimal bite function — tailored to your facial features and preferences.
Technology We Use and Why It Matters
Every piece of technology at Newton Dental Associates is selected because it improves a measurable outcome — more precise implant placement, faster healing, more comfortable procedures, better-fitting prosthetics. Here is how each system contributes to your care:
- 3D CBCT Imaging Gives us a full volumetric view of your jaw before treatment begins, so we know exactly how much bone is available, where the nerves and sinus cavities sit, and how to angle each implant for maximum stability.
- Guided Surgical Technology A custom surgical guide is fabricated from your digital plan and used during the procedure to place each implant within millimeters of its planned position. This reduces surgical time and improves accuracy.
- Digital Impressions Intraoral scanning eliminates physical impression trays, producing highly accurate digital models of your mouth for prosthetic fabrication.
- PRF / PRP Therapy Platelet-rich fibrin is derived from your own blood and used at the surgical site to accelerate tissue healing and support osseointegration.
- IV Sedation Administered and monitored by trained staff, sedation allows patients with dental anxiety or longer procedures to remain comfortable throughout.
How Much Do All-on-X Dental Implants Cost in Newton or Boston?
Pricing transparency is something we take seriously, because we know cost is a real part of this decision.
In the Newton and greater Boston area, All-on-X treatment typically ranges from $20,000 to $50,000 per arch. Full-mouth treatment (both upper and lower arches) generally falls in the range of $40,000 to $100,000 or more, depending on case complexity. Several factors affect where a specific case falls within that range:
- Whether extractions are needed and how many
- The number of implants required (4, 5, or 6 per arch)
- Whether preparatory procedures such as bone grafting or a sinus lift are necessary
- The prosthetic material selected for the final restoration (zirconia, acrylic, hybrid)
- The complexity of bite reconstruction and aesthetic customization
We provide a detailed, itemized treatment plan and cost breakdown at your consultation — before you make any decisions. Financing is available through third-party lenders, and we are happy to walk through options with you.
Dental insurance rarely covers full arch implant procedures as a whole, but portions of treatment (extractions, bone grafting, individual implant components) are sometimes partially covered. Our team will work with your insurance to identify any applicable benefits.

Frequently Asked Questions
How long do All-on-X dental implants last?
The implants themselves — the titanium fixtures that integrate with your jawbone — are designed to last a lifetime. Clinical data shows implant survival rates above 95% at 10 years when placed by experienced surgeons in carefully selected cases. The prosthetic arch (the teeth you see) has a longer functional lifespan than traditional dentures, but may require adjustment, refinishing, or replacement after 10 to 20 years depending on wear patterns, bite forces, and material. At Newton Dental Associates, your follow-up care is structured specifically to monitor the health of your implants and the condition of your prosthesis over time, so any maintenance can be addressed before it becomes a larger issue.
Is the All-on-X procedure painful?
The surgical procedure itself is performed under anesthesia — you will not feel pain during placement. Most patients who choose IV sedation report little to no memory of the procedure. Post-surgical discomfort in the days following surgery is typically managed with over-the-counter pain medication and prescription anti-inflammatories. Swelling and mild soreness in the jaw are common for the first several days. The majority of our patients describe their recovery as significantly easier than they anticipated. If you have concerns about pain or anxiety related to dental procedures, please raise them at your consultation — there are multiple sedation options available to ensure you are comfortable throughout.
Am I a candidate if I have significant bone loss?
Bone loss is one of the most common reasons patients are told they cannot have implants — and in many cases, it is not accurate. The angulated implant placement used in All-on-4 and All-on-X techniques was specifically developed to work with reduced bone volume. The posterior implants are tilted to engage denser, more available bone at the front of the jaw, often eliminating the need for bone grafting even in patients with substantial resorption. During your consultation, we take a CBCT scan and evaluate your bone precisely. If additional bone volume is needed, grafting can be performed and healing allowed before implant placement. The only way to know for certain whether you are a candidate is to have a proper evaluation — not to take someone else’s word for it.
How much do All-on-X implants cost in Newton or Boston?
Per-arch pricing in the Newton and Boston area typically ranges from $20,000 to $50,000, depending on the complexity of your case, the materials selected, and whether preparatory procedures are needed. Full-mouth treatment (upper and lower arches) typically falls between $40,000 and $100,000 or more. These figures reflect the full scope of care: consultation, imaging, surgery, the temporary prosthesis, and the final custom restoration. We provide a complete, itemized cost breakdown at your consultation before you commit to anything. Financing options are available, and we can help you navigate any potential insurance benefits.
Can I really get a full set of teeth in one day?
Yes. On the day of your surgery, implants are placed and a temporary fixed prosthesis is attached before you leave. This temporary arch is functional and natural-looking — you can speak and eat soft foods immediately. It is not a removable appliance; it is fixed to the implants. The permanent final prosthesis is delivered three to six months later, once your implants have fully integrated with the bone. So while the final teeth take time, you are never without a fixed, functional smile at any point during the process.
What is the difference between All-on-4 and All-on-X?
All-on-4® is a specific, trademarked protocol developed by Nobel Biocare that uses exactly four implants per arch in a defined configuration. All-on-X is the broader clinical category that describes full arch implant treatment using four, five, or six implants, depending on the patient’s anatomy and bone density. Some patients benefit from additional implants for greater load distribution or long-term durability, particularly those with higher bite forces or specific bone characteristics. At Newton Dental Associates, we plan implant number and position based on your individual anatomy and goals — not based on a fixed protocol.
What can I eat after All-on-X implants?
During the healing period (roughly three to six months), we recommend a soft food diet to protect the temporary prosthesis and allow the implants to integrate without excessive load. Think cooked vegetables, fish, pasta, eggs, and similar textures. Once your final prosthesis is in place and the implants are fully integrated, most patients can eat a normal, unrestricted diet — including foods that were off-limits with dentures. Chewing on hard objects (ice, pens, hard candies) is discouraged for anyone with a fixed prosthesis, as it can cause chipping regardless of material.
Do All-on-X implants look natural?
Yes, when designed correctly. The final prosthesis is custom-fabricated to match the size, shape, and color of natural teeth, proportioned to complement your facial features and gumline. Dr. Amini-Sami, as a prosthodontist, specializes specifically in the aesthetic and functional design of dental prosthetics. The prosthesis material — typically zirconia or a high-grade acrylic-titanium hybrid — is selected for both appearance and durability. We review the design with you before fabrication so you have input on the final outcome.
How do I care for All-on-X implants?
Daily maintenance is straightforward. Brush the prosthetic arch at least twice a day with a soft-bristled toothbrush, and use a water flosser or interdental brushes to clean underneath the arch along the gumline. Regular professional cleanings at Newton Dental Associates are essential for monitoring implant health and keeping the tissue underneath the prosthesis clean. Most patients come in for cleanings every three to four months in the first year, then transition to twice-yearly visits once everything is stable. Implants can fail if the tissue around them becomes inflamed (a condition called peri-implantitis), so consistent hygiene and professional maintenance are non-negotiable parts of long-term success.
