All-on-4 Dental Implants

All-on-4 is a full-arch tooth replacement system that uses just four strategically placed implants to support a complete, fixed set of non-removable teeth. By angling the posterior implants, Dr. Chaves can often avoid bone grafting and deliver a stable, natural-looking smile in fewer visits than traditional implant methods.

You Don't Have to Live With Tooth Loss

Roughly 175 million Americans have lost one or more teeth, and that number keeps growing. The good news is that modern dentistry makes living without the stigma and challenges of tooth loss entirely possible.

Dental implants are the most natural-looking and natural-behaving replacement teeth available — but the standard implant procedure isn't always physically viable or convenient for everyone. In those situations, the All-on-4 procedure is often a better solution.

What is All-on-4?

All-on-4 is a minimally invasive method of placing a full arch (upper or lower) of fixed, non-removable replacement teeth using only four implants. You get a complete set of teeth without multiple surgeries or replacements.

The procedure can typically be completed in our office during a single appointment under local anesthesia. For patients who have lost all their teeth or need remaining teeth extracted due to decay, this is a remarkable advancement — a full set of teeth that look real and act like the originals, without undergoing multiple procedures.

The Process

  1. 1

    Detailed examination

    We review your records, existing conditions, current dentures, facial structure, and every factor that influences implant placement.

  2. 2

    3D CT imaging

    3D scans of the jawbone map the positions for replacement teeth while revealing the precise location of bone, sinuses, and nerves.

  3. 3

    Digital simulation

    A computer simulation positions the implants at the optimal angles for maximum support, and we fabricate your new set of teeth to your needs.

  4. 4

    Implant surgery

    Under anesthesia, the four implants are placed directly into your jawbone and your new teeth are secured — typically in a single appointment.
