Then the sites are cleaned and bone grafting is performed. On the day of surgery, all the remaining teeth are removed. The patient can also choose to be put to sleep for the procedure. These 4 dental implants are placed in each arch by skilled dental professionals under profound local anesthesia for minimizing pain and discomfort. Thorough assessment of bone quality and volume is important. The surgical phase involves radiographic assessment with the help of x-rays and a cone beam CT scan. The whole procedure involves two main stages. The All-on-4 concept is most frequently used for people who prefer teeth that stay in the mouth permanently. Temporary teeth are provided on the same day of surgery so the patient is not toothless. All on 4 can support approximately 12-14 teeth. The all-on-4 concept for replacing missing natural teeth is basically a technique to replace all missing teeth in an arch with only 4 dental implants. To summarize 10-12 implants are needed for all on 4, but only 6-8 for snap-on teeth. On the other hand, all on 4 bridges need at least 4-6 dental implants when a complete arch of teeth is being replaced. Implant supported dentures need only two to four implants for support as the denture flanges provide additional support. The biggest problem with standard dentures (other than they are unstable) is it changes speech and alters taste by covering up the palate.Īll on 4 implants need more implants than Snap-in Secondly, snap-in dentures do not cover the palate with plastic. First, the snap in system helps the teeth stay in the mouth and remain stable even while eating hard foods and talking. There are 2 clear advantages of snap-in teeth vs traditional dentures.

What is All on 4 Full Mouth Implants VideoĬontact Dr. Acrylic teeth are also called “hyrbid dentures.” Clear Choice for example offers acrylic as the standard teeth and the zirconia teeth are an upgrade for a higher price. Acrylic is basically a high grade plastic. Zirconia implant teeth last a lot longer than acrylic because they do not wear, break or absorb plaques and smells.Ī much cheaper version of all on 4 teeth are made out of acrylic. Zirconia is a lot like ceramic and is very smooth, strong, thin and does not stain or break. Zirconia is basically a high grade porcelain. The other very obvious difference is snap on teeth are made of acrylic and all on 4 is made out of zirconia. All on four is not removable and never comes out of the mouth during eating, teeth cleaning or ever unless the dentist uninstalls them. All on 4 teeth are permanently installed into the mouth and are completely supported by implants. The biggest difference is snap-on dentures are removable and need to be taken out for proper maintenance and hygiene. If the existing implants aren’t placed parallel to each other, they will give you issues later on with how your overdenture will fit and stay on when you’re chewing.Permanent implants is a much different full mouth implant option. Are the existing implants placed at the proper angles? If you’re doing an implant overdenture, also referred to as snap-on denture, then it’s critical that the implants be placed parallel to each other. However, every case is different so you would need a consultation to see if your existing implants could be used.Īlso, there is another factor that is involved with the ability to use existing implants. As a result, it’s most likely that your existing implants in your mouth most likely won’t be able to be used for an All on 4 or implant denture prosthesis. Your implant will be placed lower in the bone than it would have been normally had your implants been placed for a single tooth or bridge. In order to maintain that height, your surgeon will have to “clear space” in your mouth by bringing your bone and gum level down a few mm. In order to ensure your prosthesis will be able to fit inside your mouth and not affect your bite height, also known as the vertical dimension of occlusion, your surgeon will have to ensure that the top of the implant to the edge of your prosthesis (or the edge of the tooth) has to not violate your vertical dimension. For instance, a hybrid prosthesis, which is a titanium substructure with acrylic gums and teeth on top of it, must be at least 12-15 mm thick to ensure that there is enough bulk of material so it doesn’t break when chewing. The weaker material, the thicker it must be. The stronger the material, the thinner it can be. These prostheses all must have a minimum thickness, depending on how strong the material is.
