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

Asad A | February 26, 2024

Missing teeth can significantly impact your confidence, smile aesthetics, and oral health. Fortunately, advancements in dental technology offer solutions like All-on-4 dental implants, restoring complete arches of teeth with a fixed and stable alternative to dentures. But a critical question remains: How long do All-on-4 dental implants last?

All-on-4 Dental Implant: How Long Do They Last?

Long-term studies provide encouraging evidence for the durability of All-on-4 implants.

A 10-year longitudinal study involving 245 patients found:

  • 98% of implants remained functional after five years.
  • 95% of patients had no implant failures after five years.
  • 95% of implants and 94% of patients remained successful after ten years.

This success rate is better than expected for a new treatment, considering the inherent possibility of implant rejection. Interestingly, 99% of the dentures attached to the implants remained in good condition after ten years.

A second study from 2012 followed a similar number of patients for five years and reported:

  • 98% implant success rate.
  • 100% success rate for the dentures.

Dr. Paulo Malo, the pioneer of All-on-4 treatment, participated in both studies, ensuring the reliability of his techniques. These studies suggest implant-supported dentures are a viable long-term solution for full mouth restoration. While research beyond the current 10-year limit is unavailable, patients can expect relatively few complications with implants and dentures throughout their lives.

Tips to Make All-on-4 Dental Implants Last Longer

Just like with traditional dentures and implant-supported crowns, proper care can extend the lifespan of your All-on-4 implants.

  • Choose a Skilled Dentist: Opt for a dentist experienced in dental implants, especially the All-on-4 technique. Their expertise can significantly reduce the risk of implant rejection.
  • Maintain Excellent Oral Hygiene: Consistent brushing and rinsing are crucial for your dentures and oral health. This minimizes the chance of damage or rejection. Brushing your remaining teeth before getting All-on-4 helps maintain a healthy jawbone, improving implant success.
  • Prioritize Your Overall Health: Address conditions like poor circulation, compromised immune system, or slow healing, as they can impact implant success. While soft food can ease oral pain, stick to a balanced diet rich in nutrients to maintain strong jawbone tissue. Manage blood sugar, improve circulation, and prioritize general health to reduce implant failure risks.
  • Select Durable Denture Material: Avoid plastic and acrylic for long-lasting dentures. Opt for stronger materials like zirconia or porcelain, especially if you retain natural teeth. These are more resistant to wear and tear from natural teeth than plastic or acrylic, preventing damage to both the implant and natural teeth.
  • Quit Smoking and Limit Alcohol: Smoking and excessive alcohol consumption can cause dry mouth, which weakens gums and hinders healing after surgery. Even resuming these habits later can stain dentures and potentially lead to implant rejection.
  • Follow Dietary Adjustments: During the initial three months post-surgery, solely consume soft foods to allow proper implant integration with your jawbone. Your dentist can provide a list of safe post-surgery foods and menu ideas. Once healed, avoid hard or sticky foods to prevent potential damage or breakage of the implants.

However, don't rely solely on soft food. The jawbone needs stimulation from moderate chewing to maintain its density. Aim for a balanced diet rich in lean protein, vegetables, fruits, and shelled nuts for optimal nutrition and moderate chewing stimulation.

  • Address Teeth Grinding: This habit wears down natural teeth and damages denture materials. The pressure exerted on implants during grinding also increases the risk of breakage or failure. If unable to stop grinding at night, use a custom night guard from your dentist that accommodates your dentures' size and shape.

By following these guidelines, you can significantly increase the lifespan and functionality of your All-on-4 implants, allowing you to enjoy a confident smile for years to come.


Knowing "How long do all-on-4 dental implants last?" is crucial for maintaining optimal oral health and making informed decisions about dental care. By understanding the factors influencing implant longevity and adopting proper maintenance practices, patients can ensure the durability of their dental implants for years to come.

On average, dental implants boast a success rate of approximately 95%, translating to a failure rate of typically less than 5%.

All-on-4 dental implants are crafted to resemble natural teeth and are securely anchored in the mouth through the use of four or more implants positioned along the jawbone. While the occurrence of food becoming lodged underneath them is possible at times, employing precautionary measures and maintaining proper care typically resolves this issue.

It's advisable to clean All-on-4 dental implants at least twice daily, ideally after each meal. Use a soft toothbrush and gentle soap or mouthwash to thoroughly remove food particles and prevent bacterial accumulation in the area.
