What is an All-on-4?

 All-on-4 is a dental implant technique that uses fewer implants in the upper or lower jaws than the traditional methods. This procedure can also avoid the need for certain grafting procedures. On average, a traditional full dental implant rehabilitation of the upper jaw would require between 8 and 10 implants, whereas the new technique would only need 4 implants. With the All-on-4 technique, the rear implants are inserted at a 30 to 45 degree angle rather than vertically. With this new method, patients who suffer of bone loss can still be eligible for the procedure without going through the extensive and lengthy process of a bone graft.

Who can benefit the most from an All-on-4 technique?

The ideal candidate for an All-on-4 are patients who have lost all their upper or lower teeth or patients who have bad teeth that need extraction or are planning to remove all remaining non-viable teeth and want to replace them. The removal of teeth with the All-on-4 procedure can be done on the same day as the implant placement.

How is the All-on-4 technique different from dentures?

Dentures are custom made to each patient’s jaw and fit over the gums. They stay in place using suction or sometimes require the help of dental adhesive. However, over time, the supporting bone shrinks, and the denture becomes looser. Denture needs to be replaced regularly to avoid discomfort. The All-on-4 technique involves dental implants are permanently inserted into the jaw bones. There is no risk of the teeth slipping away while eating or talking. There are several other differences between the All-on-4 technique and a denture including; a more natural look, the ability to eat all foods.

What are the advantages of the All-on-4 technique?

The major advantage of the All-On-4 technique is the that the patient leaves the office with teeth in their mouth and the ability to chew food on the day of the surgery. This differs from the conventional technique that requires a minimum of 3 months before putting any pressure on the implants.

Here are some more advantages of the new dental implant technique:

  • No bone graft required
  • Durable teeth
  • Easy maintenance
  • Short treatment and recovery time
  • Long-term results
  • Increases self-confidence and improves quality of life
  • Very high successful rate (more than 95%)
  • Lower cost

What are the steps to follow for an All-on-4 technique?

 First your surgeon will examine the soft tissue in your mouth. They will then evaluate the jaw bone using medical imaging, called cone-beam, computed tomography. They will also discuss oral or IV sedation options for you. Don’t forget to mention the source of your reference.

  1. Following the exam, the team will provide you with the details and the estimated cost of the procedure.
  2. If you do not already have a prosthodontist, we will be happy to refer you to a specialist who can take good care of your teeth.
  3. During the appointment with your prosthodontist, they will analyze the optimal position of the implants with the help of the scan and will take an impression to make the initial prosthesis.
  4. On the day of the surgery, our oral surgical team will prepare a sterile environment for surgery which will reduce the risks of complications. Since this is one-day procedure, you will be able to leave the same day with your prosthesis in your mouth.
  5. A soft diet is recommended for 6 weeks following the procedure.
  6. A follow-up appointment will be scheduled one week after the procedure to make sure that you are healing properly.
  7. Another follow-up appointment will take place about 6 to 8 weeks after your procedure. A radiograph will be taken to see help assess the healing of the implants.
  8. Finally, with the approval of your surgeon, you will return to your prosthodontist who will create your final prosthesis.

What is the success rate with an All-on-4 technique?

All-on-4 dental implant technique is a fairly new approach; however, studies show good success rate after 10 years, with 99.2 % of prostheses and 94.8% of implants themselves lasting longer than 10 years.
