All-On-4 Teeth in One Day

The All-on-4® Treatment Concept is a cost-efficient, graftless solution that provides patients with a fixed full-arch prosthesis on the day of surgery.

Dr. Spiro Karras is an internationally recognized All-on-4® expert

Tooth loss, gum and bone disease affect millions of people worldwide, on every continent, in every age group. Globally, several hundred million people are thought to be missing one or more teeth. More than 40 million people are estimated to be fully edentulous in the Western world alone. Complete tooth loss is a much more widespread handicap than most of us realize. Major barriers for solving the problem are the perceived complexity, stagnant technology and high cost of treatment. With innovative new solutions this no longer needs to be the case. There is a solution. A cost effective, proven solution.

Patients suffering with uncomfortable and painful dentures, and those patients living with unsightly partial bridges – causing even more damage to their remaining teeth and gum line – now have a clinically proven, FDA accepted treatment option for replacing missing or non-functional teeth.

All On 4 ChicagoThe procedure maximizes the use of available bone to allow for the palcement of dental implants and a new, functional set of teeth on teh same day. Using only four implants in the jaw, the AO4 solution takes advantage of the benefits of tilting the posterior implants to provide a secure and optimal prosthetic support for a prosthetic bridge, even with minimum bone volume. In conjunction with Nobel Biocare, the world leader in innovative restorative and esthetic dental solutions, European researchers and clinicians developed the AO4 procedure based on their pioneering Immediate FunctionT capability, which is specifically designed for people with dentures or in need of full upper and/or lower restorations. The major benefit to the AO4 procedure is how quickly dentures can be replaced with permanent implants and fixed, non-removable, new replacement teeth.

Dr. Karras is among most experienced surgeons in the United States, and is recognized as an expert and Key Opinion Leader, in the life changing AO4 procedure for those patients who are candidates. In fact, he travels internationally and teaches other doctors how to perform this revolutionary technique.  Unlike other approaches that can use six, eight, or even more implants per arch, and often involve bone grafting, Dr. Karras uses this proven technique that involves only four specially placed implants, usually without bone grafts or other ancillary surgical procedures, meaning lower costs and reduced healing time. And the success rate of AO4 is superior to more traditional approaches, and is designed to last a life time.
