You’ve likely heard of dental implants, but All-on-4 dental implants take tooth replacement to the next level. This modern approach in implant dentistry makes replacing a full set of teeth more efficient, comfortable, and transformative.

Unlike traditional implants that replace teeth one by one, All-on-4 offers a complete smile makeover using four implant posts to support a full denture. The result? A stronger, stable, and natural-looking smile and bite with fewer appointments and minimal surgery.

At Sierra Dental, our All-on-4 implant team is led by our oral surgeon Dr. Choo-Soon Kua, who has experience in the All-on-4 technique, and Dr. Javier Cabrales, our periodontist, skilled in guided implant surgery and pre-implant surgical procedures. Together, they create life-changing smiles that our patients can enjoy for a long time.

What is an All-on-4 Implant

What is an All-on-4 Implant?

All-on-4 dental implants is a modern solution for a complete set of missing teeth. Instead of using a traditional implant that can support just one tooth, this treatment relies on four titanium implant posts positioned strategically on the jawbone to permanently anchor a custom-made implant-supported denture.

These implants are placed at precise angles to maximize bone support and stability. This treatment is recommended even for patients with some bone loss. With no bone grafting required, All-on-4 Implant is a less invasive, quicker, and relatively more affordable treatment.

Benefits of All-on-4 Dental Implants

Choosing All-on-4 dental implants can do wonders to your confidence, comfort, and long-term oral health. Here’s what makes this treatment stand out for our patients:

perfect teeth and smile that feels natural

Feels natural, looks beautiful

Unlike traditional dentures which can shift around and feel bulky, All-on-4 implant-supported dentures are securely anchored to the jawbone. This means that you do not have to worry about your teeth moving out of place when you talk or smile. They are designed to appear lifelike and remain comfortable.

Improves everyday comfort and confidence

Eat, laugh, speak just as naturally as you would. With All-on-4 implants, you can enjoy your favourite foods again, smile freely, and live your life in the best way. Our implant team ensures each treatment restores not just your teeth, but your quality of life.

Helps preserve jawbone health

One of the consequences of missing teeth is bone loss over time. But All-on-4 implants help keep the jawbone strong by stimulating bone growth. The implants act like natural tooth roots where bone can remain stable to prevent the “sunken” facial look. As a result, your smile will look more youthful and natural-looking.

Designed for long-lasting results

At Sierra Dental, we use durable materials to ensure your new smile will remain healthy and beautiful for years to come. With proper care, All-on-4 dental implants can last for decades, making this a worthwhile investment to your smile and oral health.

Am I A Candidate for All-on-4 Dental Implants?

Wondering if All-on-4 dental implants are the right choice for you? Here’s what our implant specialists look for when determining if you are a good fit for the treatment:

Candidate for All-on-4 Dental Implants

Age and Smile Goals

All-on-4 implants are ideal for adults who have lost most or all their teeth and want a permanent, natural-looking replacement. The good news is that age is not a barrier as long as your gums and jawbone are healthy enough to support the implants.

Adequate Bone Support

Unlike traditional implants that may require more bone density, All-on-4 dental implants only need four strong anchor points for full stability. If you have thinner bone structure, Dr. Cabrales, our specialist for bone grafting, may recommend a graft to strengthen the area.

Healthy Gums and Oral Health

A clean, infection-free mouth is important to the success of this treatment. So, if you have existing gum disease or periodontitis, we need to create a treatment plan to solve this before starting the implant procedure.

Excellent Overall Health

The state of your general health plays a big role in the healing process of implants. With that, patients with uncontrolled diabetes or autoimmune disorders may not be eligible for treatment. A thorough medical evaluation with your physician is important in understanding if you are a suitable candidate.

At Sierra Dental, we begin every implant treatment with a patient screening and personalized consultation. By ensuring that each patient is an excellent candidate, this sets the stage for a safe, smooth, and successful treatment.

About the All-On-4 Procedure

With in-house specialists and trained dentists in our clinic, our All-on-4 implant procedure is designed not only for long-term success, but also for your comfort. Here’s what you can expect:

All-On-4 Procedure

Step 1: Consultation and Treatment Planning

Every smile transformation starts with a detailed and personalized consultation with our implant specialists. During this visit, we will assess your oral health and bone structure using digital X-rays and 3D scans. This also helps with determining where to place your implants for predictable results.

Step 2: Pre-Procedures

In some cases, additional steps like bone grafting or sinus lifting may be recommended to create a stronger foundation for your implants.

Step 3: Implant Surgery

Our team uses guided implant surgery with a digital workflow to place the four implant posts with precision and accuracy. The surgery is typically done under local anaesthesia. But for anxious patients, we also offer other sedation options to make sure you are as relaxed as possible.

Step 4: Healing and Osseointegration

After surgery, the implants will gradually fuse with the bone in a process called osseointegration which should take 4-6 months. Our team will discuss post-surgical tips to guide you through a healthy recovery. During this time, you will wear temporary dentures so you can still smile and eat while you wait for your permanent dentures.

Step 5: Customized Implant-Supported Dentures

Once the implants are fully healed, our team will fit your custom-made dentures. These are designed to match your facial features, support your bite, and improve your smile.

Step 6: Long-Term Care and Maintenance

Your new smile deserves care that will help it stay healthy and look brand new for years. This includes improved cleaning techniques, regular check-ups every six months, and professional maintenance appointments.

All-On-4 Vs. Traditional Dental Implants

While All-on-4 is a type of dental implant, there are many ways in which it differs from the traditional treatment process. Here’s how they compare:

Fewer implants, full smile

Traditional dental implants often require one post per missing tooth. This means multiple surgeries and longer healing times if done for a full set of teeth. With All-on-4, we only need four implants for a full arch of teeth.

Shorter treatment time, lower cost

Because All-on-4 implants require fewer posts and often skip one grafting for eligible patients, this means fewer dental appointments and more affordable costs than the traditional method.

Better patient compatibility

Traditional implants may not be recommended for patients with bone loss or limited bone density. But, All-on-4 implant supported dentures will remain stable in the mouth even with only four anchor points. This makes it a great choice for many patients who were once told they are not ideal implant candidates.

All-on-4 Dental Implants FAQs

No, it is not painful. In fact, we often hear from our Calgary patients how surprisingly comfortable their All-on-4 dental implant procedure was. The treatment is performed under local anaesthesia so you will stay comfortable during surgery. For added comfort, Sierra Dental also offers IV sedation, oral sedation, and laughing gas. You can discuss this with your dentist so we can include it in your treatment plan.

With proper care, All-on-4 dental implants can last for decades. The implant pots are designed to be permanent, while the implant-supported denture attachment may need replacement only after several years.

Like any surgical procedure, All-on-4 dental implants carry some risks, so proper planning and care is important to reduce any complications. Possible risks include:

  • Infection
  • Nerve irritation or damage
  • Implant failure due to poor healing
  • Allergic reaction to materials used

At Sierra Dental, transparency and fair pricing is among our commitments to our patients. With that, all our fees follow the Alberta Dental Association (ADA) Fee Guide. As a starting point, you can expect All-on-4 dental implant cost to start at $20,000 per arch. Your exact cost may vary based on your specific needs and treatment plan. Our team will be sure to discuss the cost and procedure before any work begins so you know exactly what to expect.
