What You Have to Know About the All-on-4 Before Making a Decision


These days, the All on 4 implant treatment is growing more and more popular, as seen it how many dentists are offering this treatment option on Google Adwords. Because this treatment is a big investment, patients should know all of their options and possible long term results before they make a decision.
It may surprise you to learn that the “All-on-Four” technique was invented 20 years ago by Dr. Paulo Malo, a dentist in Portugal, in cooperation with Nobel Biocare. All on Four is an economic type of implant supported full mouth reconstruction. This procedure tries to avoid more expensive procedures like sinus lifting or nerve relocation when placing implants, and thus may require distal implants to be placed in an angled position. Multi-unit abutments are placed on top of the implants to ensure intop restoration. However, these abutments do come with some drawbacks, such as requiring many screws which often break and make the All on Four difficult to keep in good condition. The restoration portion of the All on Four is traditionally composed of a metal bar lined on the outside with acrylic and denture teeth. Recently, many patients have discovered that this type of restoration can easily break and stain. Zirconia bridges have proven to be a marked improvement in this regard.
The following are some additional advantages and disadvantages of the All-on-4:
1) Teeth in a Day - A maxillofacial C.T. scan aids the oral surgeon, prosthodontist and technician to plan & provide the convenience of same day delivery of a fixed detachable prosthesis.
2) It has been used in other countries for many years.
3) It is F.D.A. approved.
4) It circumvents anatomical areas, ie. maxillary sinus, mandibular nerve and may eliminate the need for bone grafting.
1) Can be considerably more expensive than other reconstructive options.
2) The failure of one implant will necessitate replacement and a prosthetic remake.
3) It requires adequate bone volume for the placement of long & angled implant fixtures.
4) It doesn't use as many implants for prosthetic support as more conventional procedures.
At AllNew Dental, our innovative team of experienced dentists and dental technicians, with the help of the most advanced dental technology available today, have made a few key refinements to the way we perform the All-on-Four procedure that ameliorate or in some cases entirely eliminate the above-mentioned drawbacks.
