Fixed Hybrid Overdentures Procedure

Dr. Michael Costa and Dr. Stephen Malone of Knoxville Smiles at Malone & Costa Dentistry offer the highest standard in dental implant treatment for patients who have lost all of their teeth on the upper or lower arch or will soon be losing all of their teeth. This treatment often is called “All-on-4” because a hybrid overdenture denture can be fixed with screws on as few as four dental implants and the entire process of inserting the dental implants and having the hybrid denture attached can be accomplished in the same day. Due to the unique design of the implant system, patients can typically receive this treatment without need for costly bone grafting or sinus lift procedures.

A hybrid denture is a full denture (including prosthetic teeth and gum tissue) that completely covers the alveolar ridge and is firmly retained by a minimal number of dental implants. A full titanium bar supports the denture to ensure against breakage. All slippage is eliminated. Unlike removable full dentures, hybrid dentures do not cover the palate of the mouth. This means you will be able to taste and enjoy your food. Many patients forget they have a hybrid denture because it feels, functions, and looks much like a natural arch of teeth.

A multi-unit abutment from Zimmer Biomet allows for the tilting of the two back implants. This means longer Zimmer Biomet implants can be positioned in the front part of the jawbone, rather than in the back where the bone is often resorbed. This reduces the need for vertical bone augmentation (grafting). Anchoring the implants in better quality bone improves support for the denture. The forward placement helps avoid critical nerves, and in the case of an upper denture, helps avoid the maxillary sinus.

Both the upper and lower arch can be treated in this manner. With proper care, hybrid dentures that are supported and fixed on implants can last the rest of your life.

We offer complimentary (no fee) initial and second opinion implant consultation appointments. In this appointment, you will learn about appropriate implant treatment for your individual oral health situation, and your questions will be answered. We will explain financing options available through CareCredit and LendingClub Patient Solutions. You may take time to make your decision, and you will not be under pressure to schedule treatment.
