What Are All-on-4 Dental Implants?
All-on-4 is a full-arch restoration that replaces an entire row of upper or lower teeth using just four implants. The two rear implants are placed at an angle — up to 45 degrees — to reach areas of the jaw with greater bone density, which allows the procedure to deliver a stable, fixed result even when bone volume is limited. Patients leave with a non-removable set of teeth that looks, feels, and functions like natural dentition.
How All-on-4 Works
Conventional implant treatment for a full arch involves one post per missing tooth and requires adequate bone density throughout. All-on-4 achieves the same end result — a complete, fixed set of teeth — with four implants total, relying on the angled rear posts to access bone that is more reliably preserved even after prolonged tooth loss. For most patients, this means fewer procedures, no bone grafting, and a more direct path to a finished smile.
Treatment Timeline
Most patients walk out of their surgery appointment with a provisional fixed arch already attached, which is the basis of the “teeth in a day” reputation. That temporary prosthesis stays in place during the osseointegration period, which takes several months as the implants fuse with the surrounding bone. Once we verify that integration is complete, the final permanent restoration is crafted and placed. Start to finish, the full process typically runs six to twelve months.
Benefits of All-on-4
All-on-4 provides permanent stability, a natural appearance, improved chewing efficiency, and bone preservation. Patients appreciate not dealing with the slipping, adhesives, or ongoing maintenance of traditional removable dentures. The implants themselves are designed to last a lifetime with proper care.

Frequently Asked Questions About All-on-4 Dental Implants in Staten Island
What are All-on-4 dental implants?
All-on-4 is a full-arch restoration that replaces an entire row of upper or lower teeth using just four implants. The two rear implants are placed at an angle — up to 45 degrees — to reach areas of the jaw with greater bone density, which allows the procedure to deliver a stable, fixed result even when bone volume is limited. Patients leave with a non-removable set of teeth that looks, feels, and functions like natural dentition.
How does All-on-4 differ from placing individual implants?
Conventional implant treatment for a full arch involves one post per missing tooth and requires adequate bone density throughout. All-on-4 achieves the same end result — a complete, fixed set of teeth — with four implants total, relying on the angled rear posts to access bone that is more reliably preserved even after prolonged tooth loss. For most patients, this means fewer procedures, no bone grafting, and a more direct path to a finished smile.
How long will the All-on-4 restoration last?
The implants are designed to be a permanent part of your jaw. They integrate with the bone and are not something that comes out or requires replacement under normal circumstances. The prosthetic arch secured to them is fixed in place for daily life, though it can be accessed by your surgeon for professional maintenance. The prosthesis itself may eventually need to be updated after years of wear, but the implants anchoring it are built to last as long as you care for them.
What does the All-on-4 timeline look like?
Most patients walk out of their surgery appointment with a provisional fixed arch already attached, which is the basis of the “teeth in a day” reputation. That temporary prosthesis stays in place during the osseointegration period, which takes several months as the implants fuse with the surrounding bone. Once we verify that integration is complete, the final permanent restoration is crafted and placed. Start to finish, the full process typically runs six to twelve months.
Is All-on-4 surgery painful?
IV sedation or general anesthesia is used for All-on-4, so the procedure itself is not something you will be aware of or feel. Some soreness and swelling in the days following surgery are normal and expected given the extent of the treatment. Prescribed medication and a clear recovery plan keep that discomfort manageable. The feedback we consistently hear from patients is that the recovery was easier than the scale of the surgery led them to expect.
Will I need bone grafts before All-on-4?
The angled implant approach at the core of All-on-4 is designed specifically to work around the bone loss that would otherwise require grafting. By positioning the rear implants to reach denser bone further back in the jaw, most patients can move forward without any preparatory bone grafting procedures. Whether your case falls into that majority is something we confirm through CT imaging during your evaluation at our Staten Island office.
How do I keep All-on-4 implants clean?
Because the arch is fixed, cleaning around and beneath it requires a bit more intention than brushing natural teeth. A soft-bristled toothbrush handles the surfaces, and a water flosser is the most effective tool for flushing out the area under the prosthesis where a regular floss cannot reach easily. Regular professional cleanings on the schedule we recommend round out the routine. We provide a detailed care plan at the time of your procedure so none of this feels like guesswork.
What does All-on-4 cost at your Staten Island office?
Pricing depends on the complexity of your case, the materials selected for your prosthesis, and whether any additional treatment such as extractions is needed beforehand. Insurance coverage for All-on-4 is limited but not nonexistent — some plans extend partial benefits toward implant treatment. Our team will help you work through what your plan covers and what financing options may be available.
