What Are All-on-4 Dental Implants? Understanding the Procedure and Benefits

what are all-on-4 dental implants

A good number of restorative options for the treatment of missing teeth are recognized as accepted dental therapy, depending on the particular circumstances of the patient. One of them is All-on-4 dental implants, a remarkable teeth replacement option. 

A longitudinal study that was done in 2011, tested the longevity of the All-on-4 implants in around 250 patients over a 10-year period and reported a success rate of 94-95%. In this blog, we will discuss this remarkable treatment, expand on the procedure that dentists and patients follow, along with the various functional and aesthetic benefits offered.

What Are All-on-4 Dental Implants, an Overview

In the All-on-4 implants treatment, foundational support for the full-arch prosthesis is provided with four implants. That is where the ‘four’ in ‘all-on-four’ comes from. Using four implants surgically drilled into your jawbone, the artificial arch of teeth that will be placed using four implants can offer unparalleled stability and secure fit that edentulous patients suffering from extensive tooth loss can’t find in traditional alternatives that rely on suction, adhesives, and the like.

Invasive procedures like bone grafting, which involves replacing degraded bone with bone from the patient, an animal, or a synthetic substitute, can be bypassed with All-on-4 implants.

Implant Placement Strategy: The two anterior dental implants, along with the two posterior implants, are strategically placed at a 45-degree angle, an orientation that helps to reach more bone, leading to significantly more secure anchorage within the jawbone and uniformly distributing the biomechanical loads of chewing and biting.

Permanence and Stability: All-on-4 dental implants are designed to be like permanent teeth and derive most of their strength and stability from within the jawbone, made possible through the critical biological process of osseointegration. This process involves the strong fusion of our body’s natural bone with the prosthesis, making advanced full arch restoration techniques not only feasible but highly effective.

Suitability and Comparison: Depending on various individualized factors, the right dental restoration technique must be specific to your unique case, with your suitability playing the most significant role. We’ll next compare the financial costs, potential benefits, and drawbacks of some full arch restoration alternatives and describe each in detail while ensuring the risk of a failed dental implant is minimized.

Procedure of All-on-4 Implants

The procedure of placing All-on-4 implants begins just like any other medical procedure, with an initial consultation with a professional in the field. In our case, you will visit a dentist who has substantial experience in this field. 

Initial Consultation

During your consultation with the dentist, a comprehensive discussion that covers all the aspects of the treatments will take place. The dentist will review your goals and desires as a patient, review existing conditions, present treatment options (implant and non-implant), answer any remaining clinical questions, and present financial estimates or options for payment. The dentist will discuss all of these items with you and also assess any radiographs and diagnostic models, if available, to illustrate points about your existing condition and treatment options. Demonstration models, brochures, flip charts, videos, photos of similar cases, patient testimonials, and any other visual aids might be used to support the dentist’s recommendations.

Planning and Diagnostic Procedures

New dental technology, materials, and designs have vastly improved the dental implant procedure. Advances in scanning technology have sky-rocketed diagnostic accuracy and speed. Using a CT scanner, a dentist can make preliminary plans for dental implant surgery through 3-D imaging by creating a virtual mock-up of the mouth, called the ‘guide’, which may eliminate an incision through the gums to find the bone. For the patient, this could mean lesser amounts of pain and healing times. 

Implant Placement

Using the plastic guide, the dentist will gently place the implants in the mouth. Tiny sleeves are etched onto the guide in places where they will drill the implant holes (socket).

The implant will be made of titanium, a biocompatible metal that the body does not treat as invasive, and will be placed into the socket. 

Long Term Integration

A remarkable process that gives implants the staying power of natural teeth comes into play in this stage. Osseointegration is the body’s biological process of fusing with the prosthesis that has been attached to the jawbone. After the surgery, over a period of a couple of weeks or months, the body will gradually heal and solidify with the titanium-made implant. During this time of healing, the dentist might advise you not to smoke or eat difficult-to-eat, hard foods.

Benefits of All-on-4 Dental Implants

To properly understand what are all-on-4 dental implants, it’s important to understand their advantages as well. There are a range of functional and aesthetic benefits that the All-on-4 implants can provide us.

Immediate Functionality

 In one single visit to the dentist, one can have an immediate temporary set of teeth installed. This type of rapid one-day prosthetic placement makes this treatment one that patients more readily opt for, as long-waiting times and uncharacteristically frequent visits to the dentist, which are features of traditional methods of restoration, can be undesirable.

An Upgraded Chewing And Biting Force

Traditional implants and dentures have up till now, only been able to restore a mere percentage of the biting and chewing forces of natural teeth. All-on-4 Implants on the other hand, can restore almost exactly the same levels as natural, that is of course, after the osseointegration process has done its work and the final, permanent prosthetic is placed.

Natural Appearance

 It isn’t an exaggeration to say that the new artificial teeth will look almost exactly the same as your real teeth, and only upon a good deal of close inspection can you tell the difference. A team of technicians works hard to create the accurate look that makes this possible. They work meticulously on the shapes, hues, colors, level of light reflection, and many more subtle aesthetic factors to reach a promising natural result.

Structural Support For The Face

Many people who suffer from compromised teeth (teeth damaged due to trauma or missing teeth) suffer from a certain ‘sagging’ of the face. This can make the face look more aged and asymmetrical. The All-on-4 implants address the lack of structure that makes this occur and restore youthful symmetry in the contours of the face.
