All-on-4® Treatment Concept

A Proven Choice for Cutting Edge Dental Implant Treatment

The All-On-4® treatment concept is the most economical option for stable dental implant treatment with attractive esthetic results. This protocol uses a prosthesis strategically supported by four dental implants that are biomechanically positioned for maximum stability. Both the Teeth In A Day® and computer-guided implant protocols can be performed using the All-On-4 Treatment Concept.


The All-On-4® treatment concept is not new. Using four implants to support permanent teeth happened for the first time at Pi in 1987, and has continued to be a reliable and effective resource for new smiles through a quarter of a century. The success rate for prostheses built upon four implants in each arch is the same as the success rate for cases requiring more anchorage. Using the 3-D scans from the cone beam CT scanner perfects the planning process.


All-On-4® allows a patient to choose from a wide variety of approaches to the fabrication of their new smile. The final prosthesis can be made in various grades of laboratory materials from acrylic to fine porcelain, always with the same attention to esthetic detail, but allowing for the financial investment to suit the patient’s comfort zone. The beauty of this system is that it is upgradeable. Additional implants can be added later and/or we can fabricated the prosthesis with a higher grade of materials at the patient’s convenience.


Permanent teeth add comfort, confidence, vigor, and vitality to the quality of life. Dental implants using the All-On-4® treatment concept are unequivocally the best alternative to limping through life with removable dentures. Besides the priceless psychological benefits of natural-looking teeth, a fixed smile eliminates lifelong visits for the relining of removable dentures as the gum and bone tissue perpetually recedes. It also eliminates the need for an ongoing supply of adhesive products.


Unmatched laboratory technology allows us to create each new smile with extraordinary sensitivity, customization, and detail. Our doctors and laboratory technicians take pride in their ability to build smiles distinctively suited to each face and personality. This premium level of esthetic care is part of every All-On-4® treatment package.


The surgical procedure for the All-On-4® treatment concept is minimally invasive and can almost always be accomplished simply by using local anesthesia. Our very experienced team of professionals provides comprehensive pre-op and post-op information to ensure that each patient has the most comfortable experience possible in our center. Recovery time is brief and gratification is instant. The new smile is placed upon the implants immediately following the surgical procedure.

For more anxious patients, the Pi Dental Center provides general anesthesia through the services of an experienced, board-certified anesthesia team.
