What are All-on-4® dental implants?

All-on-4® dental implants are a type of teeth replacement solution that uses at least four dental implants to support an entire arch of prosthetic teeth. This type of implant is ideal for people who have lost most or all of their natural teeth and need a more permanent solution than dentures. All-on-4 dental implants from Msmiline Cosmetic Dentistry in Pierrefonds, Quebec, provide stability and security, allowing the patient to speak, eat, and smile confidently. They also help maintain a healthy jawbone structure by providing stimulation where natural teeth would otherwise be present.

The procedure is quicker and less invasive than traditional implant procedures since it only requires a few implants implanted into your jawbone instead of several individual ones. Additionally, All-on-4® treatment typically results in shorter recovery since only four implants need to be placed.

All-on-4® dental implants offer many advantages over traditional dentures or other tooth replacement options:

  • They provide a secure, stable fit that allows you to eat, speak, and smile confidently.
  • They help maintain a healthy jawbone structure by providing stimulation where natural teeth would otherwise be present.

  • They require fewer visits to the dentist for maintenance compared to dentures.
  • The prosthetic teeth look and feel like natural teeth and are designed to fit perfectly with your existing bite pattern and facial features.
  • All-on-4® dental implants allow you to regain your smile and enjoy life without worrying about slipping dentures or uncomfortable gums.

Teeth Beyond Saving? Why not consider All-On-4 dental implants?

All-On-4 or Teeth in a Day – When the teeth are in the terminal phase, that means they’re not savable anymore. One of the options for replacing these teeth is complete extraction of these teeth, placing several dental implants, and fixing a denture or a denture porcelain on top of these teeth. Basically, what happens is, we’ll remove the teeth, we’ll file the bone a bit, we’ll place the implants, and we’ll place a temporary the same day that the teeth are taken out. The patient has to stay with these temporaries for a period of three to six months, and after that, these temporaries are taken out and replaced by the final product. It’s quite comfortable from the perspective of satisfaction. People are normally satisfied 95 percent with the treatment.

All-On-4 Dental Implants

Can I eat normally with All-on-4 implants, or are there any long-term dietary restrictions?

After the healing phase, you can enjoy most of your favorite foods. All-on-4 implants provide strong biting power, similar to natural teeth. However, to prevent damage to the prosthetic, avoid very hard or sticky foods (like ice, caramel, or hard nuts). Dr. Mirmooji will provide personalized aftercare tips to help you maintain a balanced, implant-friendly diet.

Will my speech be affected after getting All-on-4 implants?

Some patients notice a temporary adjustment period as their tongue gets used to the new prosthetic. Minor speech changes—like a lisp—can happen initially, but most people adapt quickly within a few days or weeks. Practicing common words and reading aloud can help speed up the process. If any issues persist, Dr. Mirmooji can fine-tune the fit of your prosthetic for better comfort.

How long do All-on-4 dental implants last?

With good oral hygiene and regular dental checkups, the implants can last 20 years or more, often a lifetime. Depending on wear, the attached prosthetic (your new teeth) may eventually need maintenance or replacement after 10–15 years. Dr. Mirmooji will monitor your restoration at routine visits to ensure it stays in excellent shape.

Is bone grafting necessary before getting All-on-4 implants?

In many cases, no bone grafting is required. That’s one of the advantages of the All-on-4 technique—it’s designed to maximize the use of existing bone, even in patients with bone loss. However, if significant deterioration is present, Dr. Mirmooji may recommend minimal grafting or a custom treatment plan to ensure long-term stability.

Can smokers get All-on-4 dental implants?

While smoking doesn’t automatically disqualify you, it can increase the risk of complications such as implant failure or delayed healing. Dr. Mirmooji encourages patients to stop smoking before and after implant surgery. If you’re a smoker, let the team know during your consultation so they can assess your individual risk and help guide you through a safe treatment process.

What kind of maintenance do All-on-4 implants require?

All-on-4 implants are easier to care for than traditional dentures but still need daily attention. Brushing twice a day, using a water flosser or floss threaders, and regular professional cleanings are essential. Dr. Mirmooji may also recommend special tools or rinses to keep the area around the implants clean and healthy.

What should I do if one of my All-on-4 implants becomes loose?

If your prosthetic or implant feels loose or uncomfortable, contact Dr. Mirmooji immediately. It could be a minor issue—like a loose screw—or a sign that further evaluation is needed. Avoid chewing on the affected side, and don’t try to fix it at home. Prompt care helps prevent complications and keeps your smile secure.
