Long-Term Value of All-on-4® Compared to Alternatives

Understanding the different treatment options available is crucial if you're considering full-mouth restoration

Teeth play a massive role in oral health and overall well-being. They are an essential part of the digestive system, helping with biting, chewing, and grinding up food before it is swallowed.

Even a single missing tooth can disrupt this process, reducing the functionality of the mouth and chewing, which in turn can compromise nutrition. In severe cases, this can eventually result in increased risk for diseases and mental illness and exacerbate pre-existing health problems.

According to the Australian Institute of Health and Welfare, adult tooth loss is relatively common in Australia. Survey data reveals that for those aged 65 and over, around 19.1% had experienced edentulism—a condition that refers to a person having lost all of their natural teeth.

Fortunately, restorative dentistry has come a long way over the past few decades, with various treatment options now available for full-mouth restoration. These methods include the All-on-4® treatment and alternatives like dentures and overdentures.

Understanding the different treatment options available is crucial if you’re considering full-mouth restoration.

This article will cover the long-term value and maintenance of the All-on-4® treatment compared to traditional restoration methods so you can be better informed when deciding what’s right for you.

The Maintenance of Full-Mouth Restoration

One of the key differences between the different types of full-mouth restoration options is the maintenance. Below, we’ve outlined the most common treatments available and their care requirements.

Dentures: Dentures are one of the oldest forms of full-mouth restoration, with the concept dating back thousands of years. Dentures are removable oral prostheses that can replace a full arch of teeth on the upper jaw, lower jaw, or both.

When dentures are designed for someone living with edentulism, this is known as full dentures or complete dentures. They replace an entire arch of teeth and rest atop the gums. Dentures rely on the palate, the roof of your mouth, and/or the lower jawbone ridge for support.

Below is a list of the general daily care steps someone living with dentures would take.

  • Taking out and rinsing the dentures after eating to prevent bacteria build-up and get rid of food debris.
  • Twice daily, in the morning and before going to bed at night, brush the dentures using a soft-bristled toothbrush and denture cleaner.
  • Most dentures also need to stay moist to keep their shape. So, every night, the dentures should be placed in a denture-soaking solution. This will keep it clean and moist.

As with other forms of full-mouth restoration, it is also important to attend regularly scheduled dental check-ups.

A combination (crowns, implants, veneers): In some cases, where a person has lost and damaged some or most of their teeth, a combination of treatments may be used to restore full-mouth functionality. These may include traditional implants, veneers, and crowns.

While the maintenance required will depend on the exact treatments used, the upkeep for traditional implants, veneers, and crowns is quite similar. The basics for all three treatments include:

  • Staying on top of your oral healthcare routine. This includes brushing twice daily, flossing regularly, and using mouthwash to help kill bacteria.
  • Avoid any hard and sticky foods.They can damage the treatment material and, in the case of traditional implants, increase the risk of failure.
  • Always use a soft-bristled toothbrush and stick with fluoride toothpaste.A hard-bristled toothbrush can damage traditional implants, veneers, and crowns.
  • Stay on top of regular visits to the dentist. Dentists are essential for preventative care and can help identify any potential issues early.

Overdentures: Overdentures are a traditional form of full-mouth restoration that blends together dentures with implants. They are for patients who have lost some or all of their teeth. They can either be supported by traditional implants or the patient’s remaining teeth.

The maintenance required for overdentures is similar to that of traditional dentures. Brush your overdentures every day, as well as softly brush your gums. It is important to use special denture cleaners with a low-abrasive formula because dentures are typically 10 times softer than natural teeth.

Overdentures need to be removed every night to soak in a denture-soaking solution or tablet. This helps keep it clean and kill any bacteria. The big difference between overdentures and dentures is that extra care needs to be paid to the gums if it’s supported by traditional implants.

Just like all oral hygiene, regular cleaning and mouthwash are important. This will help eliminate all the bacteria in the mouth and keep the implants supporting the overdentures healthy.

Dental Implants, like All-on-4® : Like the other full-mouth restoration options, caring for teeth following the treatment requires diligent home oral care and sticking to the scheduled professional check-ups. However, there is a key difference between All-on-4® and other methods. Compared to traditional implants, dentures, and overdentures, are the most similar to natural teeth. You won’t have to take out your prostheses every time to clean them. Instead, you would care for your new fixed teeth like you would natural ones.

General maintenance for fixed teeth would include:

  • Regularly brushing your teeth and gums twice daily using a soft-bristled toothbrush.
  • Flossing daily with specifically designed implant floss, such as Xfloss, and a water flosser to remove any plaque and food debris.
  • Invest in mouthwash and rinse your mouth twice daily. This can help eliminate bad bacteria in the mouth and protect the implants.
  • Attend six monthly hygiene appointments with your All-on-4®provider.

When it comes to good oral hygiene, a lot of it is habit and muscle memory. 

Longevity of Full-Mouth Restoration Options

Longevity is a key factor when choosing between All-on-4® and traditional full-mouth restorations. Average lifespans are outlined below.

Dentures: Most complete dentures last 5–10 years, with an average lifespan of about 10 years. Longevity depends on material, oral hygiene, and lifestyle habits. Common materials include acrylic resin, porcelain, and partial metal frameworks.

Combination Treatments (Crowns, Implants, Veneers): Lifespan varies by treatment and material.

  • Traditional implants: Up to 25 years with proper care

  • Crowns:

    • Porcelain-fused-to-metal or lithium disilicate: 5–15 years

    • Zirconia: 15+ years

  • Veneers: Around 10 years with proper care

Overdentures: Overdentures typically last longer than standard dentures. With proper maintenance, overdentures and supporting implants can last up to 20 years.

Dental Implants – All-on-4®: Designed as a long-term solution, lasting 20+ years with proper care. Studies show high success, with implant survival rates of around 80% over 20 years and short-term success rates of over 99%.

Tips For Increasing The Longevity of Your All-on-4® Teeth

Like natural teeth, All-on-4® requires consistent care if you want them to last as long as possible. This includes diligent oral hygiene, attending regular dental check-ups and professional cleaning.

If you’re considering a fixed teeth solution, we’ve compiled a list of tips below.

Good Oral Hygiene Habits

Staying on top of your oral hygiene is critical for increasing the longevity of your All-on-4® teeth. Regularly brush your teeth at least twice daily with a soft toothbrush and X-floss after every meal.

Invest In a Water Flosser

Research shows that water flossers, also known as oral irrigators, are more effective than other types of flossers. They’re better at removing plaque and food debris, especially in hard-to-reach areas.

Healthy Lifestyle Habits

Lifestyle habits play a massive role in the success and outcome of the treatment. Like with natural teeth, lifestyle habits like smoking and alcohol can negatively impact dental implants and teeth longevity.

Diet and Nutrition

What you eat plays a massive role in your gum health and overall well-being. A poor diet can increase disease risk factors, like diabetes, affecting oral health. A well-balanced and nutritious diet, avoiding any hard and sticky foods, is crucial if you’re looking to increase the longevity of your All-on-4® teeth.
