Full mouth dental implants is also called All on 4 or All on 6 or even All on 8 dental implants.


As its name says, all in 4 means that only four implants will be used to support a complete prosthesis that will replace all the missing teeth in a maxilla (upper or lower). This process minimizes the total number of implants required to rehabilitate the entire mouth. The 4, 6, or 8 implants work together to support your new prosthetic teeth.

Dentures are not the solution

However, any people who have lost their natural teeth use full dentures. After all, full dentures offer an inexpensive way to get your smile back.

However, dentures do not prevent bone from resorbing. This reabsorption is capable of generating structural changes that affect the structure and shape of our faces.

In addition to the fact that they can loosen over time, they can be annoying when talking and eating.

And, most importantly of all getting a full-mouth restoration with dental implants (Both dental arches) can help restore your smile and prevent difficulties speaking or chewing your food. They are the best treatment option to replace lost natural teeth.

Who is a candidate for full mouth restoration with dental implants?

People who have lost most or all of their teeth and are also in good general health and oral health are ideal candidates for full-mouth dental implants.

In terms of needs, anyone who has lost their teeth and is looking for the best method available today to restore their smile is also a candidate. Also, if you wear dentures but don't feel safe and comfortable with them, you can consider implant treatment if you have trouble speaking and eating.


However, some health conditions could impede implants, such as uncontrolled diabetes, which can prevent the proper healing process. If you are not willing to quit smoking, it will be challenging for your oral .tissues to be suitable for the procedure.

All on 4 dental implants (upper or lower)

All on 4 dental implants is an immediate rehabilitation technique for patients who have lost all of their teeth. Its name "all-on-4" means everything in 4 dental implants. It is a graft-less surgical procedure that provides patients with a full-arch prosthesis on the same day of surgery.


The All on 4 dental implants technique is ideal for patients with little bone. Long-term denture users often have this problem. Without enough bone to support implants, many were told that dental implants would not be possible without a bone graft. The 45-degree angulation design used for the all-on-4s overcomes this hurdle.

By placing the implants at specific angles, each can better distribute biting and chewing forces, thus eliminating the need to put as many implants.

All on 6 dental implants (upper or lower)

In the same way, the All on 6 dental implants treatment offers people a full and fixed arch dental prosthesis on six implants on the same day of the intervention.

The "all-on-6" technique is indicated for people with lower bone density and a more powerful chewing force. Benefits of all-on-4 and all-on-6 techniques:

The quality of life of the patient improves, the same day of the surgery leaving the surgery with a complete provisional prosthesis on the same day of the intervention.
The treatment times are much shorter; therefore, obtaining definitive teeth is also minimized.

Stability is achieved despite not having a large amount of bone. Although the quality and quantity of bone are low, all-on-4 and all-on-6 dental implants are more extended than conventional implants to contact the bone. The all-on-4 technique is for patients with medium bone resorption and all-on-6 for those patients with more severe resorption where more stability is required.

All on 8 dental implants (upper or lower)

This technique uses eight dental implants and is very similar to the popular all on 4 dental implants. It is the most stable option because it involves the largest number of dental implants. It has the strongest grip on the jaw, providing a bite force much closer to natural teeth.


But, All-on-8 implants require the patient to have enough bone to support all eight implants. Many long-term dentures or trauma patients may not have enough bone for eight implants. In this case, it will first be necessary to make bone grafts, which I will lengthen.

Comparing All on 8, All on 6, and All on 4

All on 4 dental implants and All on 6 dental implants are a faster, cheaper alternative. The fact that fewer implants are required makes the procedure faster, easier, and more comfortable for the patient.


In addition to being inexpensive, All on 4 dental implants and All on 6 dental implants generate a significant reduction in treatment time since the denture can be fixed as soon as the implants are placed.

Although All on 8 dental implants are indeed a good option and perhaps the most stable and robust, it is necessary to have enough bone structure to support the eight implants; otherwise, it will be required to start with bone reconstruction grafts, which means that the treatment will take longer and also involves additional costs.

In conclusion, both techniques involve drilling into the jawbone, but all-on-4 implants require fewer implants, making a big difference.
