All on 4: What is it?

What are All-on-4 dental implants?

All-on-4 is a comprehensive dental implant program that completely replaces failing teeth with dental implants.

With the All-on-Four treatment concept, natural teeth are surgically removed and replaced with four implants and a hybrid-type bridge.

While this procedure is an innovative technique in dental implant treatments, it is not without potential risks and complications. It's an aggressive and complicated treatment, which happens to be the most widely marketed procedure in the field of implant dentistry.

Potential patients must understand that all-on-4 is neither simple nor easy; in fact, it's the most complex implant treatment in dentistry.

All-on-Four procedures must be methodically planned, and it is imperative that a Plan B is in place before the treatment begins.

Advantages of the All-on-4 technique

The All-on-4 dental implant technique offers several significant advantages. It boasts a higher success rate compared to traditional implantation methods. The procedure, typically lasting between 1 and 3 hours, is well-tolerated and provides complete oral rehabilitation. A notable aspect is its feasibility in patients with diabetes, osteoporosis, or other health problems often considered contraindications to bone grafting. In just a few days, the entire process, including dental surgery and the placement of immediate functional teeth, is completed, unlike traditional methods which may require multiple interventions over more than a year. Furthermore, the resulting teeth have a natural appearance and function similarly to natural dentition. Finally, this technique stands out for its hygienic aspect, offering ease of maintenance and cleaning.

Disadvantages and limitations of All-on-4 treatment

Despite its numerous advantages, All-on-4 treatment is not without disadvantages and limitations. Some patients may experience difficulties related to the initial recovery phase, presenting with swelling, bruising, and discomfort. Moreover, while this technique is often feasible in patients with certain health conditions, there remain cases where it may not be recommended. The costs associated with the All-on-4 procedure can also be a barrier for some individuals, as they may be higher than those of alternative options. Additionally, the need for rigorous dental hygiene persists, and complications such as plaque buildup can occur. Finally, although the overall success rate is high, there is still a potential risk of implant failure in some patients. It is essential to consider these disadvantages and limitations when making a decision about All-on-4 treatment, carefully weighing the advantages against potential challenges.

What is the process for All-on-4 dental implants?

All-on-Four is a simplified implant procedure where only four implants per arch are needed (or eight implants for replacement of all teeth).

The process begins with a dental examination and assessment, including an evaluation of your functional needs and aesthetic desires. The initial consultation is a good opportunity for you to ask questions about treatment options, and for your implant specialist dentist to develop a personalized treatment plan.

At this stage, your dentist will use state-of-the-art diagnostic imaging tools to determine if your bone density and volume are sufficient for this procedure.

In some cases, preparatory dental work may be necessary before all-on-4 dental implants.

How to determine if you are a good candidate for All-on-4?

The ideal candidate profile for All-on-4

The decision to extract all your teeth should never be made quickly or lightly. You need to have thorough discussions with your implant specialist dentist to ensure all potential issues are addressed before treatment begins.

Generally, eligibility for dental implants rests on several criteria, including robust oral health, a sufficiently favorable dental health status to undergo surgery, and being a non-smoker. More specifically, if you are facing issues such as a poorly fitting denture, total tooth loss, the need for a bone graft, or if you are looking for a suitable implant solution, All-on-4 treatment could be a relevant option for you.

Bone density requirements and required scans

Complex dental implant cases require adequate bone in both quality and quantity. All-on-4 implants must be performed on teeth with a sufficient bone base to support the entire structure. Without adequate bone, dental implants will not hold and bridges may become detached, leading to catastrophic failure.

Implant specialist dentists regularly utilize technologies such as scans and computer-generated surgical guides to develop the best possible treatment plan, ensuring the best possible outcome for this complex procedure.

Pre-operative instructions and advice

Before your All-on-Four procedure, your dentist will provide detailed guidelines likely including several of the following instructions: ensure you brush your teeth before the appointment, wear loose, comfortable clothing, refrain from smoking or consuming alcohol for at least 24 hours before the procedure. If general anesthesia is planned, refrain from eating or drinking for at least eight hours before the operation. It is also recommended to have a responsible adult accompany you to the dental office, thus ensuring your transportation and waiting in the waiting room during the procedure. Furthermore, be sure to use the restroom before the operation if necessary, and make all necessary financial arrangements in anticipation of the intervention.

All-on-4: Post-operative

Recovery and healing time

The post-operative recovery period may be longer and involve more discomfort than other implant procedures, although pain and swelling generally decrease within three days of the operation, with progressive improvement thereafter.

Furthermore, significant bone reduction may be necessary and this trauma can lengthen recovery times.

Adequate maintenance after All-on-4

Long-term care of All-on-4 implants can be more challenging than that of other implant restorations. The reason is that hybrid bridges prohibit easy access to the implants themselves. This makes routine care more difficult for the average person.

Has the All-on-4 implant yielded positive results in your case?

After opting for the All-on-4 implant, it is relevant to question the results obtained in your particular situation. Have you noticed significant improvements in terms of dental stability and overall functionality? Did this implant solution meet your expectations in terms of comfort and dental aesthetics? Explain your post-operative experience, highlighting the advantages you have observed or, if applicable, the challenges encountered. By sharing your perspective, you will contribute to enriching the collective understanding of the results of the All-on-4 implant and informing other people considering this option.

Other treatment options

If you require complex implant treatment such as All-on-4 dental implants, you may also be a good candidate for alternative treatments that ensure complete oral health through less invasive or less expensive procedures.

Remember that dentists performing dental implants often differ on their specific treatment suggestions.
