Everything You Need to Know About Becoming a Candidate for an All-on-4 Dental Procedure

All-on-4 is a dental implant technique that uses four strategically placed dental implants to support a full arch of replacement teeth. Unlike traditional implants, All-on-4 requires fewer implants, making it a more affordable and less invasive option. This procedure is ideal for people who are missing multiple teeth or who have experienced bone loss.

One of the most significant benefits of the All-on-4 implant procedure is that it can restore your confidence and improve your quality of life. With All-on-4 dental implants, you can eat, speak, and smile comfortably while enjoying a beautiful, natural-looking set of teeth.

In this guide, we’ll take you through everything you need to know about becoming a candidate for All-on-4 dental procedure, including the candidacy requirements and the alternative options. So, whether you’re considering All-on-4 implants for yourself or a loved one, read on to discover if this is the right option for you.

  • All-on-4 technique uses four dental implants to support a fixed dental bridge that replaces all missing teeth in an arch.

  • The All-on-4 method requires fewer implants compared to traditional implant techniques. This reduces cost and the need for bone grafting.

  • Factors determining candidacy for All-on-4 dental implants include jawbone density, oral health, overall well-being and commitment to good oral hygiene.

  • The All-on-4 dental implant procedure involves evaluation, planning, and placement of dental implants and post-operative instructions for patients.

  • Benefits of All-on-4 dental implants include restored chewing function, improved oral health, and boosted self-esteem.

What Are All-On-4 Dental Implants?

All-On-4 dental implants are a popular restorative dental treatment for people missing multiple or entire arches of teeth. This technique uses four dental implants to support a fixed prosthesis that replaces all missing teeth in the upper or lower arch. The four implants are strategically placed at specific angles to maximise the available bone in the jaw and provide a stable foundation for the replacement teeth.

Traditional implant techniques, like implant-supported dentures, require 6-8 implants to replace a full arch of teeth. In some cases, a single implant is used for each missing tooth. Meanwhile, the All-On-4 technique requires only four implants to replace an entire arch of teeth. This significantly reduces the cost of the procedure and eliminates the need for a bone graft procedure. As such, it is more comfortable and looks like natural teeth.

The All-On-4 dental implant procedure typically involves several appointments.

During the first appointment, the dentist will determine if you are a good candidate for All-on-4. To do this, they will:

  • Assess your oral health.
  • Take X-rays and impressions of your teeth.
  • Plan the placement of the dental implants.
  • The dentist may perform additional procedures like extractions, bone grafts, or other pre-treatments if necessary.

During the succeeding appointments:

  • The dental implants will be placed in the jawbone and will be allowed to fuse with the surrounding bone for the next 3-6 months.
  • The dentist will place abutments or connector pieces on the dental implants. The abutments will then be left to heal for a few weeks to allow the surrounding tissue to heal and stabilise.
  • The dentist will take impressions of your mouth to create a custom-made prosthesis that fits securely onto the abutments.
  • The false teeth (or the prosthetic teeth) will be attached to the implants via the abutment.

The All-on-4 procedure is a minimally invasive procedure and is usually completed under local anesthesia. Sedation options are available for patients who may feel anxious or uncomfortable.

After the All-On-4 dental implant procedure, patients may experience some swelling, discomfort, and minor bleeding. The dentist will provide detailed post-operative instructions, including dietary restrictions and oral hygiene guidelines, to promote healing and prevent complications.

All-On-4 dental implants offer the following benefits:

  • Restores chewing function
  • Improved oral health
  • Boosted self-esteem

Overall, All-On-4 dental implants provide a comfortable and natural-looking teeth replacement option for people who have lost multiple teeth. Plus, with proper care, dental implants can last for many years.

Who Can Be a Good Candidate for All-On-4 Dental Implants?

The ideal candidates for All-on-4 dental implants are people who:

  • Have lost multiple teeth in one or both arches
  • Are edentulous (have lost all of their teeth)
  • Are in good overall health, free from advanced gum disease or periodontal disease
  • Have minimum jawbone density required to support the dental implants
  • Do not smoke
  • Have good oral health and are free of active gum disease or other oral infections
  • Committed to maintaining good oral hygiene after the procedure
  • Have realistic expectations for the surgical procedure
  • Willing to follow the dentist’s post-operative instructions

The dentist will thoroughly evaluate the patient’s oral health and medical history. This will help determine if All-on-4 implants are a suitable treatment option.

Is Age a Factor in Candidacy?

Age can be a factor in All-on-4 dental implant candidacy, but it is not necessarily a determining factor. Younger patients may be more likely to have sufficient bone density and better healing capabilities. However, older patients can still be suitable candidates for the procedure if they have adequate jaw bone density and good oral health.

In fact, All-on-4 dental implants can be ideal for older patients experiencing tooth loss due to age-related factors such as gum disease, decay, or wear and tear. The procedure can help restore their chewing function, improve their oral health, and boost their quality of life.

Ultimately, the dentist will evaluate a patient’s oral health and medical history to determine whether All-on-4 dental implants are a suitable treatment option, regardless of age.

Can Individuals With Previous Dental Work, Such as Bridges or Crowns, Still Be Candidates for an All-On-4 Dental Procedure?

A person with previous dental work, such as bridges or crowns, can still qualify for an All-on-4 dental procedure. However, it depends on the person’s specific situation and the location of their existing dental work. For example, if the bridge or crown is situated on the opposite arch from the intended restoration, then All-on-4 implants should not be greatly impacted. However, if the bridge or crown is situated in the area where the implants should be placed, the dentist may need to consider alternative treatment options.

During the consultation process, the dentist will:

  • Evaluate the patient’s oral health
  • Examine the condition of the patient’s existing dental work
  • Take X-rays and other diagnostic tests

All these are done to determine if the All-on-4 dental procedure suits the patient.

Sometimes, the dentist may need to remove the existing dental work before performing the All-on-4 procedure. Alternatively, they may be able to work around the existing dental work and incorporate it into the All-on-4 treatment plan.

It’s important to communicate openly with your dentist about your dental history, including any previous dental work. This will help your dentist provide you with the right treatment for your needs.

Are Individuals With a History of Smoking or Alcohol Use Still Eligible for Dental Implants?

Patients with a history of smoking or alcohol use may still be eligible for dental implants. However, these habits increase the risk of complications and affect the success rate. Thus, they may require additional considerations.

Smoking has a negative impact on oral health. It increases the risk of implant failure since it impairs blood flow and delays the healing process. Because of this, dentists recommend that patients stop smoking before undergoing dental implant surgery. To further reduce the risk of complications, these patients should also strictly follow their dentist’s post-operative instructions.

Similarly, excessive alcohol consumption can also have a negative impact on oral health. This increases the risk of post-surgical complications. People who consume alcohol regularly should discuss their drinking habits with their dentist. They must work closely with their dentist for a treatment plan adjustment.

In any case, being honest with your dentist about your lifestyle habits and medical history is important. They will develop a personalised treatment plan that takes your circumstances into account so you can receive the most appropriate and effective treatment for your needs.

Can Individuals With Certain Medical Conditions Still Be Candidates for Dental Implants?

Those with certain medical conditions may still be candidates for dental implants. It depends on the specific condition and its impact on oral health and the healing process.

Some medical conditions that may affect a person’s eligibility for dental implants include:

  • Uncontrolled diabetes
  • Autoimmune disorders
  • Certain types of cancer

Uncontrolled Diabetes

Uncontrolled diabetes can impair the body’s ability to heal and increase the risk of infection. These can be a concern following dental implant surgery because they may prolong recovery time.

However, individuals with well-managed diabetes can often still be candidates for dental implants. This is if they work closely with their healthcare provider and follow their post-operative instructions carefully.

Autoimmune Diseases

Autoimmune disorders such as lupus and rheumatoid arthritis can also affect the recovery process by weakening the immune system. As with uncontrolled diabetes, these conditions can increase the risk of infection after surgery.

However, many individuals with autoimmune disorders can still be considered for dental implants. These conditions may require special considerations when planning dental implant surgery. Treatment success often depends on the severity of the disorder and whether it is being adequately managed.


Similarly, individuals with certain types of cancer may need to delay dental implant surgery until after completing cancer treatment. Certain medications and treatments used to manage cancer can weaken the immune system and increase the risk of infection after surgery. Additionally, some types of radiation therapy may damage the tissues required for successful implant integration.

Overall, it’s important to discuss any medical conditions or concerns with your dentist and healthcare provider. They will determine whether dental implants are a safe and appropriate treatment option for you.

Your healthcare team can help you understand the potential risks and benefits of dental implant surgery. They can create a custom treatment plan according to your needs and circumstances.

How Much Do All-On-4 Dental Implants Cost?

In Australia, the cost of All-on-4 dental implants ranges from $23,000 to $27,000 per arch. However, this can vary depending on several factors, such as:

  • The complexity of the case
  • Geographical location
  • Dentist’s skills and experience
  • The need for additional procedures such as tooth extractions or bone grafting

While All-on-4 dental implants may cost more upfront than other dental restorations, they provide more benefits. They offer a more long-lasting and cost-effective treatment in the long run, as they are designed to be durable and low-maintenance.

For a more accurate idea of the cost of All-on-4 dental implants, consult a qualified dentist. They will evaluate your needs and provide you with a personalised treatment plan and cost estimate.

Alternative Options to All-on-4

There are several alternative treatment options to All-on-4 implants, and the most appropriate one for you will depend on your needs and dental situation. Here are some examples:

Traditional Implant-Supported Dentures

This option involves placing 6-8 dental implants to support a full arch of teeth. In case of inadequate bone density, this procedure will require bone grafting or sinus lift.

Complete Dentures

Removable dentures are a more traditional approach to replacing a full arch of missing teeth. They are usually made of acrylic, moulded to fit your mouth like a glove.

Unlike implant-supported dentures, conventional dentures are removable. They are not directly attached to the jaw and may shift or move during function. Denture adhesive can help stabilise it, but eventually, dentures may have to be replaced for a better fit.

While they may not offer the same level of stability as dental implants, removable dentures are a more affordable tooth replacement option.

Partial Dentures

Partial dentures are removable prosthetic devices similar to full traditional dentures in appearance, but they’re designed to replace just a few missing teeth. These dentures are fastened onto existing teeth with metal clasps.

Partial dentures can be an affordable and convenient treatment for those missing only a few teeth. However, they require more upkeep and maintenance than bridges or implants since they must be removed to be cleaned daily.

Fixed Bridges

A fixed bridge is a prosthetic device that bridges the gap between missing teeth. It involves placing dental crowns on the teeth adjacent to the gap and using them to support a pontic (replacement tooth). This option is generally used to replace one or a few missing teeth rather than a full arch.

Consult a qualified dentist to determine which treatment option suits your specific needs and situation. They can evaluate your oral health and discuss the benefits and drawbacks of each option. They can also tell you about the associated costs to help you make an informed decision.

Final Thoughts

The All-on-4 dental implants can be a life-changing treatment for people with multiple missing or damaged teeth. This innovative treatment offers many benefits, including:

However, remember that the All-on-4 dental implant technique is not suitable for everyone. The decision to undergo this procedure should be made in consultation with a qualified dentist.

Other treatment options may be more appropriate depending on individual needs and circumstances. These include:

  • Traditional implant-supported dentures
  • Removable dentures
  • Fixed bridges
  • Partial dentures

Ultimately, the ideal way to determine your candidacy for All-on-4 dental implants is to consult a qualified dental professional. They can evaluate your oral health and discuss your treatment options. They can also give you the guidance and support you need for a healthy, beautiful smile.
