What Is The All-On-4 Dental Implants Treatment?

The All On 4 Dental Implants is a procedure where the surgeon places four implants into the maxillary bone. Four implants provide a firm foundation, like pillars supporting a building. Through the superior abutment, a full-arch bridge is load and screwed. Two of the dental implants are placed straight for the maxillary bone, and the other two in an angled position.

    How Does The All On Four Works?

    The design of the All On Four treatment has developed over time as a concept. Nowadays, it is the premier solution for people that need full mouth implants on the upper or the bottom jaw.

    For the upper maxilla, four implants are implanted surgically into the bone. The implants go in an angled position or where you have a better bone density.

    The All On 4 offers the stability any mouth required to get a strong bite.
    This is the foundation of the All On Four

    After bonding with the bone, the occlusion's pressure spreads and distributes among the four implants and provides stability to load on a full-arch fixed bridge.

    Based on pure physics, four or more dental implants can support a full-arch fixed bridge restoration.

    Are The All On Four Dental Implants Removable?

    No, they are not. Only a dentist can unscrew the fixed bridge. Also, there is no further need for powders or glues; the All On 4 denture always stays in place. It doesn't pop out or slip.

    The key to the All-On-4 treatment is the grip the posts give when the patient is chewing or taking a bite.

    How Many Implants Are Needed For A Full Mouth Reconstruction?

    The surgeon verifies the number of dental implants to place into your maxilla through a CT Scan; they can also view the patient's bone density and condition and know if they need four, five, or six dental implants.

    It is possible to place up to eight implants per arch, but four to six implants are enough to support an implant overdenture. Each case is carefully evaluated with a digital and clinical evaluation.

    The surgeon will place the dental implants where the patient has a better bone density.

    What Is All On 6 Dental Implants?

    The surgeon places six dental implants into the maxilla for the All-On-6.
    Patients with a larger arch structure or good bone density could be good candidates for the All On 6.

    Four implants are the minimum, and six dental implants provide better stability.

    How To Know If I Am A Candidate For The All On Four?

    First of all, you need to have an adequate bone condition for implant placement; enough bone to insert the post. Bone density is critical for good dental implant osseointegration.

    If you are missing several teeth or you wear ordinary dentures, the All-On-4 is a good option in the next scenarios:

    1.- People who are missing most of their teeth and feel tired of "patching" of temporary fixtures only making you spend money.

    2.- People who wear ordinary dentures and feel frustrated, self-conscious, depressed, and can't eat right.

    In both cases, you could upgrade to a permanent solution like the All On 4, or what people call "permanent dentures".

    Who Is Not A Good Candidate For The All-on-4 Dental Implants?

    In some circumstances, you could unqualify for full mouth implant treatment. Patients with the next scenarios are not the right candidates for the All-On-4:


    • People with advanced problems due to bone recession.
    • People with severe periodontal disease or unattended bone infection.
    • People that went under radiation therapy during the last five years.
    • People with uncontrolled or unsupervised diabetes could be ineligible for dental implants.

    All-On-4 Vs. Dentures

    There is no way you can compare the benefits of All-On-4 Vs. Dentures. Upgrading from conventional dentures to implant overdentures is an extraordinary improvement for your health and self-esteem.

    Common Dentures

    You have to use glues and powders like Fixadent or Poligrip to keep dentures in place and reapply them when you're trying to eat something. The taste of glue can make you gag too.

    Using these adhesives regularly can also cause stomach problems.


    The fixed implant overdenture is anchored to the abutment or head of the implants that were set previously into the bone. It is a palateless, full-arch bridge that doesn't move, pop out or slip. 

    Common Dentures

    With traditional dentures, eating becomes an everyday challenge. You need to cut smaller bites and feel you cannot swallow. Or have soups, soft food, or shakes as meal replacements. You could be compromising the digestive process and decreasing your nutrition.

    With regular dentures and overdentures, you have a covered palate, and you can not taste the flavors or feel the food's temperature.


    With a fixed full-arch bridge that doesn't move, you can eat all types of foods. You can bite and chew raw vegetables, peanuts, or anything you like. You will also be able to feel the taste and temperature of the food you're eating.

    Common Dentures

    Wearing ill-fitted dentures can wreck your confidence and self-esteem in several ways; traditional dentures can make you feel depressed too. You're constantly worrying about your dentures popping out in front of people. Maybe you avoid social circumstances where you feel your teeth could compromise your security. Perhaps you avoid intimate moments and become depressed, uncomfortable, and self-conscious.


    With firm, new teeth, you can have a social life again: Smile, speak, sing, swim, and laugh with confidence. No one will notice your teeth is a fixed bridge; they look natural.

    The All-On-4 Surgery

    The setting of the tooth implants is a quick and minor surgery that takes about 90 minutes. 

    We use local anesthesia, or you can request IV sedation during the surgery.

    After the initial digital evaluation with 3D imagery - CT Scan, we create surgical guides to place the implants. All technology employed in our clinic is computerized.

    We use surgical guides in all the placement of the angled All On 4 implants in Cancun, Mexico.
    We use surgical guides to set your All On 4 implants.

    All On 4 Dental Implants Surgery Aftercare

    Should I expect pain after the surgery?

    After surgery, you could feel mild discomfort and swelling that is addressed with analgesics and antibiotics. If the patient intakes the medication, it should not hurt.

    During the first couple of weeks after the surgery, we recommend avoiding heavy exercise and smoking. Smoking through dental implant recovery could affect adequate healing.

    What can I eat after the All On 4 surgery?

    During the first couple of days and until you get your temporary denture (a few days later), you need to take soft food as smashed eggs, spaghetti, rice, fish. Avoid eating irritating or greasy food.

    How To Clean The All-On-4?

    After the dental implant surgery, you must adapt your new routine with proper oral hygiene. Strict hygiene is imperative; the patient needs to keep rigorous hygiene control.

    When we eat, food particles and debris could get stuck or trapped between the implant and the gums or between the fixed dentures. The food accumulation could cause bad breath and, in some cases, infection or abscess on the implants.

    The accumulation of food trapped in your gums could cause gum problems and infections due to the bacteria developing in your mouth.

    Daily cleaning routine for the All On Four Implants

    Step #1 Brushing

    You need to brush your teeth three times a day as if they were your original teeth. You need to use
    Use a soft toothbrush and a non-abrasive toothpaste. It would be best if you brushed after every meal and every time you can do it. Carry a brush on your car or purse. Brushing at least twice a day is a must.

    Step #2 Use water floss

    Food can get stuck between your fixed bridge and the abutments or between the implant and the gums. Therefore, water flossing is as important as brushing.

    The water floss, like Waterpik, helps us remove all the food particles that could remain in our mouth.

    We always recommend the use of WaterPik at least once a day. The Waterpik is a pressurized water floss that helps cleaning the parts your brush and floss can not reach. It is an addition you need to acquire for your daily oral cleaning habits routine.

    Step #3 Use mouthwash

    We recommend antibacterial, alcohol-free mouthwash. It not only gives you fresh breath, but it also helps us clean bacteria from our mouth.

    Step #4 Visit your dentist

    We recommend visiting the dentist's office every six months to deep clean your fixed hybrid bridge or Zirconia Prettau bridge.

    The dentist unscrews the fixed bridge and cleans into the housings, and polish it too. They will also check the gums and tissue around the implants.

    All-On-4 Frequently Asked Questions

    Can you have All On Four dental implants if you have bone loss?

    Yes, there are possibilities. Patients with bone recession could need a bone graft, a sinus lift, or zygomatic implants.

    If you have receding bone, we will place the implants where there is best bone availability. We verify the angle and position of the implant with a 3D CT Scan; surgical guides are used during the implant placement.

    • The implants: If you keep optimal oral hygiene and take proper care of your dental implants, the treatment could last a lifetime.
    • The fixed bridge: The bridge could need a replacement after six to eight years.

    Yes, they do. Bone tissue needs stimulus and pressure to stay healthy. When several teeth are missing, the bone reabsorbs, leaving fewer areas to insert dental implants.

    Six implants will give a better grip, stability, and support for the full-arch fixed bridge. If you have enough bone, six dental implants are the optimal option.

    Yes, they are. The prosthesis rests and gets the support from the dental implants, not from your gums. The full-arch bridge gently
    sits over the bone ridge and doesn't cause any sore gums or irritation.

    After a few weeks, you will forget the All On 4 is not your real teeth.

    With Teeth In A Day, a fixed bridge is load and screwed immediately after the implant placement.

    The stability is given by choosing a tapered-screw dental implant with modified grooves, an osteoconductive surface, and sufficient length (on a minimum range of 10 to 13 mm). The main requirement for immediate-loading success is initial stability. That is why the ‘teeth in a day’ is not for everybody.

    Usually, the implants placed in your maxilla or jawbone should be well-anchored in your jawbone and able to withstand a tightening torque of 35 Ncm without further rotation to load. It is convenient to wait a few months before loading any dental prosthesis.

    The ‘teeth in a day’ may shorten the treatment time, but it does not warranty in any way that it will be equally successful than waiting six months until the osseointegration takes place. The bone needs to adapt and bond to the implant, and the chances of success are higher when you wait until the implant has osseointegrated.

    Immediate loading of implant overdentures decreases the length of treatment but increases the chance of dental implant failure.

    In the '90s, a Portuguese doctor called Paulo Maló designed a new concept for a fixed overdenture.

    By 2004, Dr. Maló teamed up with Nobel Biocare, and they followed over 2,000 cases. Today, there are over 100,000 patients worldwide that have received this treatment. We use Nobel Biocare implants for your All-On-4 treatment.
