All on Four Treatment

Enjoy a new smile in one day

If you have missing teeth, you may struggle with speaking and/or chewing. Additionally, you may feel embarrassed and self-conscious when you smile. While dentures can solve these issues, you may be hesitant to receive them because of the nuisance and discomfort that can be associated with them.*

Dentures are usually placed with traditional dental implants that require bone grafting and a long healing period. Fortunately, Dr. Amin Samadian and his San Francisco team can use the All on Four or Smile in a Day dental procedure. Compared to regular implant surgery, it involves fewer implants and saves you a great deal of time. All on Four can give you a full set of teeth without recurring surgeries and general anesthesia.*

What is All on Four?

All on Four takes traditional dentures and places four dental implants, one in each of your mouth arches so that the implants can combine with your jawbone and create a firm grasp. Fewer dental implants allow for less pain and faster healing times. It can also help avoid aggressive bone grafting and sinus procedures in severe bone loss cases while delivering the same flattering results. 

In a similar procedure called All in Six, we use six dental implants to support your dentures. With All on Six, four implants are placed in the front of the jaw while two implants are placed at an angle in the back.

Reasons for All on Four treatments

Dr. Amin Samadian and his San Francisco team may suggest All on Four if you have widespread tooth loss and have previously considered dentures, yet are worried about the common concerns that come with traditional dentures like looseness and adhesives. He and his team of experts will talk with you and establish a plan that will work best for your specific dental needs.* 

Another very popular reason for receiving All on Four implant-supported hybrid dentures is if a patient has multiple missing and loose teeth and the remaining teeth are not good enough support to receive conventional bridges. In these cases, both financially and cosmetically, it makes the most sense to take all the teeth out and give the patients a single implant-supported prosthetic that can bring them perfect symmetry, color match, smile design, and function.*

What does All on Four involve?

All on Four dental implants can provide you with a full set of teeth using only four implants that support a complete arch of non-removable replacement teeth. This procedure a fantastic way to get a complete set of teeth without having to endure multiple surgeries.*

Since the procedure is minimally invasive and uses only oral sedation, the recovery period is manageable. The sedation should wear off about 4-5 hours after the procedure, so you will need to ensure someone can drive you home after your treatment. You’ll also need to follow a liquid and soft food diet for a few days.*

If you have dentures and no teeth, recovery will be very minimal. In the event you notice any pain and swelling, pain medication can help. You’ll be able to go back to work and your normal activities within two to three days.*

However, if you have remaining teeth and bone grafting is required, your healing period will be about three weeks long. You’ll come home with a temporary denture and wait about six months for the implants to integrate with your bone. After this period, you’ll return to our office so that Dr. Amin Samadian can place your final denture. You’ll be prescribed antibiotics and an antimicrobial mouthwash to prevent infection.*

What results will I see?

All on Four can allow you to once again chew with ease, prevent future bone loss, and obtain a gorgeous, healthy smile. You’ll find that Smile in a Day alleviates the hassle and discomfort that can come with traditional dentures*. You’ll be able to eat and drink as you did with your natural teeth and find that with proper care (brushing, flossing, and regular dental visits), your All on Four implants can last you a lifetime.*
