The ‘All-on-4′ is a dental implant treatment option for those with completely missing teeth. The implants can be placed either in an immediate fashion on the same day as extractions (Teeth-in-a-Day) or in delayed fashion once the extractions sites have healed (Delayed implant placement). The ‘All-on-4′ refers to placement of the entire prosthesis (i.e. teeth) on 4 dental implants. The prosthesis can be either removable or fixed.
The ‘All-on-4′ treatment is a great solution for patients who have lost significant bone in the back of their jaw and where bone grafting is not desired. The dental Implants are positioned in a way that does not require bone grafting while providing great support for the prosthesis. The ‘All-on-4′ technique can be done in both upper and lower jaws.
Four implants are the minimum number of implants for this approach. However, it may be recommended to place 5 or 6 dental implants for additional support. More implants may be recommended for those with a large biting surface or strong chewing habits. The additional implants provide greater stability, strength, and support for the prosthesis. If you love eating harder food, the additional implants will be of great benefit to you
A common scenario is a patient who needs all of their teeth extracted due to severe decay or gum disease. Here is how it works:
The implants provide complete support for the teeth and require no support from the gum tissue as in the case for removable complete set of teeth. Therefore, the prosthesis design has no flanges extending into the cheeks or palate, making it most comfortable and natural to the patient. The implants support a framework, either made of Titanium or Zirconia, which in-turn supports the teeth made of either of acrylic, porcelain, or zirconia. The teeth are held to the implants with retaining screws and hence it is fixed and not removable by the patient. Depending on the patient’s bite requirements four to eight dental implants may be recommended best judged by the condition of your oral cavity.
The treatment is highly specialized therefore strongly recommended to visit an experienced Prosthodontist and Implantologist. The treatment sequence is:
