How long do All-on-4 implants last?

February 6, 2024

Are you considering All-on-4 dental implants? This tooth replacement method, or implant-supported dentures, merges dental implants with dentures. 

While dentures are widely recognized, they can feel bulky and prone to shifting. Conversely, dental implants excel in single-tooth replacements but are less common for entire arches. With All-on-4 implants, patients gain the security of implants and the convenience of full-arch dentures. Wondering, "How long do All-on-4 implants last?" Keep reading to discover more!

What is the longevity of All-on-4 implants? 

Typically, All-on-4 implant-supported dentures last approximately ten years. While a decade might seem short, grasping the components involved is crucial. All-on-4 comprises the denture component and the four dental implants embedded in the jaw. Dental implants rarely sustain damage as they fuse with the bone to become a part of the body. 

According to a study conducted in 2017, dental implants boast a success rate of 90%-95% after ten years. Some dentists have observed these implants enduring for up to 20 years.

Conversely, the denture piece connecting to the implants may require repair or replacement within a decade. Although denture pieces are durable, they're also fragile, crafted from nylon and plastic, prone to wear and tear, resulting in weakened areas.

What are the factors that contribute to the success rate of All-on-4 implants? 

Many factors contribute to the success rate of dental implants, including:

  • The patient's age
  • The length of the implant
  • Diameter of Implant
  • Location of the implant
  • Quality of the jawbone
  • Hormonal imbalances
  • Whether the patient is dealing with an infectious disease
  • Addiction to drugs or alcohol
  • Smoking
  • Pregnancy
  • Periodontal disease
  • Whether the patient is given immunosuppressive drug therapy

Tips for Prolonging the Lifespan of All-on-4 Implants 

  • Choose an experienced dentist: Seek a dentist skilled in All-on-4 implants to reduce the risk of rejection or complications.
  • Prioritize oral hygiene: Regular brushing and rinsing help maintain dentures and overall oral health, reducing the chance of damage or rejection.
  • Enhance overall health: Improve diet and address health issues like circulation problems to minimize implant failure risks.
  • Opt for durable materials: Select zirconia or porcelain for dentures, as they withstand wear and tear better than plastic or acrylic.
  • Quit smoking and limit alcohol: Both can cause dry mouth, hindering gum health and implant healing.
  • Adjust your diet: Stick to soft foods initially post-surgery, then transition to a balanced diet to support bone health.
  • Address teeth grinding: Wear a custom night guard to protect dentures and implants from damage caused by teeth grinding.

How do All-on-4 Dental Implants compare to "Regular" Dental Implants? 

The primary distinctions between traditional dental implants and the All-on-4 procedure include:

  • Healing time and process duration
  • Placement of the implants

Traditional dental implants are positioned both in the front and back of the jawbone, with the number varying based on patient requirements, typically ranging from six to eight implants. However, patients lacking healthy jawbone or gum tissue or insufficient bone may not be suitable candidates for traditional implants.

On the contrary, All-on-4 dental implants utilize four implants placed toward the front of the jawbone, where bone density is typically highest. The implants at the rear of the mouth are angled at 45 degrees, facilitating placement even in less dense jawbone areas. This often eliminates the need for bone grafts, reducing the number of surgeries and healing time for patients undergoing this procedure.

Do All-on-4 implants offer the same stability and durability as traditional implants? 

Recent research from 2019 indicates that there's no significant difference in longevity between standard and narrower implants. Another study during the same year assessed All-on-4 patients over 10-18 years, suggesting that the All-on-4 system is a viable long-term solution for patients with missing teeth.

How long is the surgery duration?

The surgery typically lasts between two and three hours per arch.

Do I have to wait 4-6 months to get my new teeth?

Traditional implants typically require two oral surgery appointments about four to six months apart. The first involves implant placement, followed by a minor surgery months later to expose the implant tops for denture attachment. However, with All-on-4 implants, some patients can have both implants and dentures placed in a single visit, depending on their needs and oral health.
