All-on-Four® Treatment for restoring Missing or Hopeless Teeth

An exciting new development in dentistry utilizing implants is the All-on-Four™ technique. This treatment uses implants to replace an entire arch, upper or lower, with permanently placed teeth. A great deal of planning and preparation is needed. On the day of tooth removal, implants are placed and connected to a brand new beautiful and permanent smile. Dr. Brent now offers this treatment that can help patients in the Cranbury, NJ area avoid dentures and the many difficulties associated with getting used to full dentures.

How Does All-on-Four® Work?

The All-on-4® procedure utilizes 4 dental implants and the implants are ready for immediate use.  This solution is highly effective for patients who have had bone loss in their jaw either caused by dentures or a missing teeth.

The technique works by positioning 2 implants in the front and 2 in the back of the mouth (hence the all on four name). Please note that while they are ready for immediate use, the typical recovery period before they are fully integrated into the patient’s jaw will take between 3-6 months.  After healing, you will be left with essentially a permanent set of teeth.

Description of the Procedure

The All-on-4® treatment is a prosthodontic procedure (i.e. replacement of missing teeth) that provides a permanent, same-day replacement for the entire upper and/or lower teeth. The procedure is best for patients with significant tooth loss or decay and for people whose bone loss in the jaw area prevents them from getting conventionally oriented (vertical) dental implants. Many patients have tooth loss accompanied by loss of the jawbone, which can complicate dental treatment and require reconstruction of the jawbone. The All-on-4® protocol can be an alternative solution, avoiding the long and costly steps of rebuilding bone when conventionally oriented implants are used. For All-on-4® to be successful, a careful analysis of the bone structure needs to be performed. The most ideal way to evaluate the bone is by a CBCT scan. The All-on-4® protocol is for at least 4 implants to be placed in a jaw. The back implants are typically angled approximately 30 to 45 degrees from the biting plane. The head of the implant emerges in approximately the second premolar position. This will allow a molar tooth to be placed posteriorly, resulting in a denture or bridge with approximately 12 teeth.

The All-on-4® treatment concept owes its name to the very nature of the method, which consists of applying a dental prosthesis with at least twelve teeth (bridge) fixed in the jaw, based only on four titanium implants.

Rapid Improvement in Quality of Life

The All-on-4® treatment provides edentulous (tooth-less) and soon-to-be edentulous patients with a fixed full-arch prosthesis on four implants on the day of surgery. This quickly leads to improved patient satisfaction – with regards to function, esthetics, sense, speech, and self-esteem.

Advantages of All-on-4®

Shorter treatment time: Two key elements significantly reduce treatment complexity, the number of surgeries, and the overall treatment time: tilting of the posterior implants avoids the need for time-consuming procedures, while immediate loading eliminates the delays of 4-6 months with traditional implant techniques.

  1. Stability even in minimum bone volume: Tilting the two posterior implants allows for a longer implants to be used. This increases bone-to-implant contact and avoids vertical bone augmentation. In addition, the tilted implants can be anchored in better quality anterior bone, and help avoid important anatomical structures.
  2. Achieve Immediate Function: Thanks to the design and dedicated protocols, implants achieve a high initial stability, which is maintained throughout the critical healing phase. All implants can therefore be loaded with Proven long-term solution with high survival rates
  3. Rapid improvement in quality of life: Immediate implant loading with a fixed provisional prosthesis quickly leads to improved patient satisfaction. In an oral health impact profile study, 95% of 250 patients were either extremely satisfied (74%) or satisfied (21%) with their new teeth. 98% said they would definitely recommend (88%) or consider recommending (10%) similar treatment to friends and colleagues.


FAQ: How does the All-on-4® dental implant technique differ from dentures?

The All-on-4® dental implant technique provides patients with fixed (non-removable) teeth and because of this, they:

  • Are cleaned and maintained similarly to natural teeth and do not need to be removed after meals or at night time.
  • Enable you to bite down with close to a natural bite, thus allowing you to enjoy the foods you love, but couldn’t manage with uncomfortable dentures.
  • Do not shift around and cannot fall out, saving patients discomfort and social embarrassment.
  • Do not rest solely on the gums, as is the case with dentures, and therefore seldom cause irritation, inflammation and the development of sores in the mouth.
  • Dental implants promote better jaw bone health by channeling the functional stimulation associated with eating into the supporting hard tissue.
  • Can halt the progression of bone loss in the jaw and so do not require one’s bridgework to be redone every few years or so (as a result of the changing shape of the jaw).


FAQ: What does the All-on-4® procedure involve?

Getting new teeth with the All-on-4® dental implant technique typically involves one or more initial consultations with one of our experienced and compassionate dental implant team members. You will then come back to Dr. Brent for several visits of preparatory work. On the actual date of the surgery, the fitting of your new rigid prosthetic dental bridge by Dr. Brent will happen at the office of our specialist. This is followed by a schedule of follow-up appointments during which we ensure that your implants are healing properly and your new teeth are functioning optimally.

Following a healing phase of 4-6 months, a permanent version of your teeth will be created over 4-6 visits in Dr Brent’s office. At these visits the initial teeth will be removed and replaced by Dr. Brent and you will continue to use the initial teeth until the final set is completed.


FAQ: What influences failure of All-on-4®?

There are a handful of factors that may lead to implant failure, but luckily, most of these are in the hands of the patient. Smoking, heavy drinking, and not following postoperative instructions or dietary restrictions can significantly affect the chances of success. There are also certain medical conditions, such as diabetes, that can affect the success and lifespan of your All-on-4® implants; however all of these risk factors will be discussed in detail with you at the time of your consultation.


FAQ: How much time should I take off from work?

We typically recommend that you take a few days off to relax and see your recovery off to as good a start as possible. Having said this, some patients return to work the very day after the surgery! It all depends on your schedule, your constitution and how strong you feel.


FAQ: Can I get both my bottom and upper teeth replaced with All-on-4® implants?

Yes! The All-on-4® dental implant technique can be used to replace your upper or lower set of teeth, or both. Should you require full mouth reconstruction, our experienced dental implants surgeons can replace both dental arches on the same day if recommended and desirable. This can sometimes achieve better results and, of course, enables you to leave with a fully restored smile and bite.
