What is an All-on-4 Implant Supported Denture?

As shown in the diagram above, All-on-4 is a method used to permanently secure a denture with 4 strategically placed implants. All-on-4 dental implants are placed into the jawbone and act as artificial tooth roots, providing a stable foundation for the denture to attach to.

Key Points:

  • All-on-4 dental implants are “implant-supported dentures” that replace all the teeth in an arch.
  • Four dental implants per arch offer a stable and secure foundation for candidates. All-on- 6 implants are also an option for patients with diverse needs.

Benefits of the All-on-4 Method

All-on-4 offers advantages over traditional dentures and other tooth replacement options. We've included the most important benefits here:

Enhanced Appearance and Confidence
All-on-4 dentures can be designed to look like natural teeth, significantly improving a patient's facial appearance and boosting self-confidence. Patients can smile, eat, and speak confidently, knowing their teeth are secure and stable.

Preserved Jawbone and Oral Health
All-on-4 dental implants help preserve the jawbone by acting like natural tooth roots. Retaining natural bone structure is ideal and contributes to better oral health.

Improved Chewing Function
All-on-4 dentures are permanently secured to the 4 strategically placed dental implants, which alleviates the denture slippage and movement so many people experience with traditional dentures while eating and chewing.

Long-lasting Results
All-on-4 dental implants and dentures are a durable and long-term solution for overall tooth loss. When appropriately maintained with regular dental check-ups and oral hygiene practices, they can last a long time.

About the Procedure

Step 1: Thorough Assessment and Treatment Planning
Before starting the procedure, every patient must complete a comprehensive evaluation with an experienced dental implant specialist. During the evaluation, the first step is to examine a patient's oral health including:

  • Patient oral health evaluation
  • Patient dental and medical histories
  • A radiographic assessment (X-ray)
  • An impression of your mouth and teeth

Note: Today, to improve the patient experience, many dental clinics use digital smile design software and a computer-guided implant tools to formulate a treatment plan that will address each patient's individual needs and conditions.

Step 2: Precise Surgical Placement
The actual implantation process involves placing four dental implants per arch into the jawbone using a minimally invasive surgical technique. These implants are strategically positioned to provide maximum support and stability for the denture. Strategic placement reduces the need for additional bone grafting procedures. To manage pain, patients can be given a local anesthesia or intravenous sedation to ensure optimal comfort during the procedure. The selected anesthesia modality depends on the patient's needs and preferences.

Step 3: Osseointegration and Temporary Denture
Following the implant placement, a temporary denture is attached while proper healing and osseointegration occurs over the next few months. The temporary prosthesis enables patients to resume daily activities while the implants integrate with the jawbone. In this process, the implants will fuse with the jawbone. Osseointegration creates a solid and durable bond between the implants and the jawbone, providing a stable foundation for the permanent denture.

Step 4: Customized Final Restoration
Once osseointegration is complete, the temporary denture is replaced with a permanent denture that will be customized to match the desires and needs of the patient according to their unique oral anatomy and aesthetic preferences.

Step 5: Recovery and Aftercare for All-on-4 Dental Implants
Post-operative recovery and diligent aftercare are crucial for successful outcomes.

Step 6: Post-operative Care
Patients receive detailed instructions on how to care for their implants and dentures after the procedure. Proper oral hygiene practices, including regular brushing and flossing, are essential to maintain oral health.

Pain and Discomfort Management:
Mild discomfort and swelling are expected after the procedure. Pain can be managed with prescribed pain medications, over the counter drugs and localized ice application. Following prescribed pain management protocols ensures patient comfort during the healing period.

Regular Follow-up Appointments:
Schedule follow-up visits with the dental implant specialist to monitor healing progress and detect potential issues early on. Regular check-ups are crucial for maintaining the longevity of the implants and prostheses.

How Much Does All-on-4 Cost?

The cost of All-on-4 dental implants and dentures varies based on several factors, including:

  • The number of pre-treatments for the All-on-4 procedure to be successful. These costs typically include extractions and/or bone grafting.
  • The number of implants required for each arch and the materials used impact the overall cost of the procedure
  • High-quality materials may come at a higher cost, but often offer durability and aesthetics that are desired in the final restoration.

Geographic Location and Dental Practice:
Costs may differ depending on the location of the dental practice and regional economic factors. Urban areas and renowned dental clinics may have higher prices than rural areas or smaller practices.

Financing and Insurance Options:
Many dental practices offer financing options to help make All-on-4 procedures more affordable. This may include payment plans or financing through third-party providers. Some dental insurance plans may provide partial coverage for All-on-4 treatment. However, the extent of coverage varies among insurance companies and individual plans. Patients are advised to check with their insurance provider to determine their coverage options.

All-on-4 vs. Traditional Implants

A comparison between All-on-4 methods and traditional implant approaches to highlight the differences and benefits of each:

Implant Number and Placement:
All-on-4 dental techniques utilize four implants per arch to permanently secure a denture that does not have to be removed for oral hygiene. Snap-in implant supported dentures also rely on several implants and placement bars for retention, but snap-in dentures are removable and must be taken out for oral hygiene. Single implants are used to replace one missing tooth that will be restored with a crown or a bridge.

Treatment Time and Cost:
The treatment time and cost for most implant procedures is the same and only varies depending on the restorative option that will go on top of the implant.

Patient Suitability:
The All-on-4 method is particularly suitable for patients with extensive tooth loss or those who are expecting to lose most of their teeth and want a comprehensive replacement option. Traditional single implants are the best option for patients with a few missing teeth.

Am I a Good Candidate for an All-on-4 Implant Supported Denture?

The suitability for All-on-4 dental implants and dentures is influenced by several factors, including:

General Health and Bone Density:
Patients with good overall health and sufficient bone density in the jaw are typically excellent candidates for All-on-4 procedures. Adequate bone density is necessary to support the implants and ensure their stability over the long term.

Age Considerations:
While there are no specific age restrictions, patients need healthy and mature jawbone structure before undergoing any implant procedure. Bone development plays a significant role in the success and longevity of implants.

Pre-existing Medical Conditions:

Certain medical conditions, such as uncontrolled diabetes or autoimmune disorders, may affect eligibility for the procedure. A thorough medical evaluation will help determine whether a patient is a suitable candidate.

Risks and Complications
All-on-4 dental implants carry potential risks and complications as does any surgical procedure. However, these risks can be minimized with proper patient selection and skilled surgical techniques. Some potential risks include:

Infection at the implant site. Following the post-operative care instructions as directed helps to reduce the risk of infection and complications.

Implant Failure
While rare, implant failure can occur due to inadequate osseointegration or improper implant placement. Patients can mitigate this risk by choosing an experienced and qualified dental implant specialist.

Nerve Damage
Nerve injury during the surgical procedure can lead to altered sensation in the oral region. Skilled surgical techniques and precise implant placement can minimize this risk.

Prosthetic Complications
Issues with the denture prosthesis, such as chipping or fracture, may occur over time, but with regular dental check-ups, issues can be detected and addressed early.

Allergic Reactions
Although extremely rare, some patients may experience allergic reactions to the materials used in the implants or prosthesis.

Post-operative Discomfort
Mild discomfort and swelling are expected after the procedure, but they are temporary and manageable with prescribed medications and adequate rest.
