All-on-4 Dental Implants in New York City

Table of contents

The All-on-4 dental implants at our New York City practice provide a permanent solution to replace missing teeth with just 4 implants securing a fixed denture. The 4-implant denture is popular for patients seeking a full-arch restoration for complete or partial tooth loss on the upper or lower jaw. Unlike traditional dentures, All-on-4 implants feel and function like natural teeth, do not require grafting, are ideal for patients with low bone density or bone loss, and require only 1–2 visits.

What is All-on-4 Concept

All-on-4 Dental Implants - Midtown NYCThe All-on-4 treatment concept entails inserting four dental implants strategically placed to utilize bone density for optimal support. Two implants are placed in the front area, positioned at a 30–45 degree angle in the back of the mouth, and securely anchored to the temporary denture on the same day of surgery. This procedure was first pioneered by Dr. Paulo Malo in collaboration with Dr. Bo Rangert of Nobel Biocare in 1998.

Over 250,000 patients with missing multiple teeth and denture wearers have experienced the immediate function (in most cases), reduced cost, regained the ability to eat comfortably, and ultimately experienced other life-changing benefits of the All-on-4 treatment. Its effectiveness is backed by extensive research and over 100 scientific studies.

The Problem with Traditional Dentures

Traditional dentures rest on the gums, relying solely on the gums and the underlying bone for support and retention. This can lead to bone loss, making the dentures ill-fitting, uncomfortable, and loose. The problem is especially problematic for lower dentures.

Why Choose Implant Dentures?

Dentures supported by implants are more functional, durable, and low-maintenance, requiring fewer dental appointments, adhesives, creams for dentures, and replacements. Hence, despite their initial higher cost, implant-supported dentures are less costly in the long term compared to regular dentures.

The Pros and Cons of Implant Dentures



Why Choose All-on-Four Implants?

Before All-on-4 dental implants technique was developed, multiple dental implants were required to secure a complete arch of teeth. The all-on-four implants procedure is a great solution for anyone who has complete tooth loss (Edentulism) in their upper or lower jaw, in both jaws, or those who do not want a traditional removable denture.

All-on-4 Dental Implants Offer Maximum Support

With conventional dental implants also called single tooth implants, it’s often necessary to use anywhere between six and 10 implants to support an implant-supported bridge. All on 4 requires only four single implants to hold a fixed denture (arch of teeth).

By reducing the number of implants needed for All-on-4, more patients are candidates for full mouth implant supported teeth, because less implants and dental bone graft procedures are needed. This can reduce the total cost of treatment and make it a more affordable option for patients comparing to traditional dental implant treatments. With all on 4 denture, just four dental implants are required to secure a complete arch of lower teeth, while six dental implants are generally needed to secure a full arch of upper teeth.

All-On-4 Implants to Support a Lower Denture

In our implants center, four dental implants are often used to restore a complete lower denture, providing a very stable restoration. You may hear this treatment called All-on-Four. This procedure, when done by properly trained clinicians, is a very predictable solution for patients who are missing all their teeth.

Sometimes it’s even possible to fit the new teeth on the same day of surgery, this procedure is commonly referred to as “teeth in a day.” In order to properly support a full arch of teeth on only 4 implants, a special protocol for the placement of the implants is used. The two dental implants in the front of the mouth are placed vertically, just like is done with traditional dental implants, however, the back two are angled backward. This allows better support for the back teeth (molars) and also avoids vital structures of the jaw like nerves, and sinus spaces.

With this angulation, these dental implants can then be longer than average, thus creating greater stability because of increased surface contact with your jawbone. Once your new implant teeth are fitted onto the dental implants, they help to lock all four dental implants in place, ensuring your dental implants cannot move during the healing process.

Zygomatic Implants vs All-on-4 to Support Dentures in the Upper Jaw

What are Zygomatic Implants?
Zygomatic implants are made of titanium and are placed in the zygomatic bones (cheekbone), which are very strong. Zygomatic Implants can be used if you have significant bone loss in the upper jaw (maxilla) and bone grafting is challenging or undesirable. Zygomatic implants can be placed in a single procedure and have a high success rate.

The table below provides a high-level comparison between Zygomatic implants and All-on-4.

Comparison Zygomatic Implants All-on-4
Target Group Severe bone loss in upper jaw. Not candidates for traditional implants. Moderate to severe bone loss. Bone grafting can often be avoided.
Implant Placement Anchored into the zygoma (cheekbone)—Bypasses areas of insufficient bone. Four implants per arch. Rear implants are tilted to utilize available bone.
Number of Implants Two to four, sometimes combined with conventional implants. Always four implants for a full arch.
Procedure Complexity Requires specialized training due to proximity to vital structures. Less complex than zygomatic but still requires expertise.
Healing Time / Load Time Requires healing phase for osseointegration before loading prosthesis. Often allows for immediate loading, a provisional bridge soon after implant placement.
Primary Advantage Allows for implants in cases of extreme bone loss without grafting. Avoids need for extensive bone grafting; immediate loading for function/appearance



Both zygomatic implants and the All-on-4 technique offer a fixed, full-arch restoration using 4 specialized dental implants without extensive bone grafting. If you’re considering zygomatic implants, discussing the risks and benefits with New York City all on four implant specialist Dr. Rahmani or your local dentist is essential. With specialized training in full denture implants such as all-on-4, All-on-6, and all-on-8, Dr. Rahmani may recommend zygomatic implants based on the severity of bone loss and specific characteristics of your jaw anatomy.

Fixed or Removable Implant Denture?

Most people, when given the choice, will choose fixed teeth that look and function similar to their natural teeth, rather than teeth that need to be removed to clean and taken out while they sleep.

Implant-Supported Denture Procedure

The process of getting implant-supported dentures involves two main phases: surgical placement of the implants and denture fabrication and attachment. Here’s a breakdown of each phase:

Phase 1: Surgical Placement of Four Dental Implants

Phase 2: Attachment of the New Permanent Denture

The Unique Positioning of All-on-4 Dental Implants

The main difference between All-on-4 implants and traditional implants is how the implants are positioned in the jaw bone. To understand the advantages of All-on-4 implants, let’s look at how their positioning differs from traditional ones.

  • The front two implants are placed vertically right at the front of the jaw
  • The back two implants are placed on either side but are tilted backward at a 45° angle

Benefits of Angled Implants:The advantage of tilted implants placed at angles is to maximize bone contact to increase their strength and stability. The implants can be standard or longer than normal; therefore, they have more contact between the implant and the jaw bone.

Strong foundation: This strong foundation ensures the implants stay firmly in place, allowing for a temporary bridge to be securely attached after surgery.

What is the Success Rate for All-on-Four Implants?

This All on 4 procedure is one of the most successful treatments for replacing full arches of teeth. According to multiple studies the success rate of this procedure is around 90-98%.

The techniques were originally pioneered in the nineties and have been extensively tried and tested. Clinical research has found that All-on-Four offers a good long-term solution, over 5-10 years, for patients who have lost all their natural teeth.

Factors Affecting Success:

  • Bone quality
  • Guided surgery
  • Implant length and diameter
  • Prosthetic material
  • Abutment type and prosthetic screw tightness
  • Expertise and experience of the surgeon

I have to say my experience exceeded all my expectations! I came with a severe wisdom Tooth pain and was on pain killers for 4 days. Doctor suggested to extract the tooth. I was super scared of the whole process but doctor and all the stuff made me feel very calm and assured that procedure will be painless and there’s nothing to worry about. Everything took about an hour, with x-rays, numbing and actual procedure. Besides being very professional and knowledgeable doctor has an outstanding sense of humor which made my visit absolutely worry-free! It’s been a week after my tooth extraction, I feel amazing, everything is healing and I didn’t even have a severe swelling. I highly recommend this place. Confident 5 stars, I would give 6 stars if there would be an option
