All-on-4, Reimagined with Smile XZ
Smile XZ is our proprietary approach to full-arch dental implants, developed by Dr. Jason Collier and available only at Southern Dental Implant Center. This advanced method gives us full control over every step of your treatment, from digital design to final placement, all performed in-house for precision and consistency. Using cutting-edge 3D technology, we design each smile to match your unique facial features and aesthetic goals.
On the day of surgery, implants are placed and scanned using photogrammetry, allowing us to align your pre-designed smile with exact implant positions. We then create and 3D print a custom provisional prosthesis that is secured the very same day, so you leave with a beautiful, functional smile right away.
Within a week, you will receive the SXZ1, a durable full-zirconia prosthesis built for strength and comfort. After a healing period of three to six months, we begin creating the SXZ2, our most refined and aesthetic restoration. If your case requires more support than what four implants can provide, we also offer the All-on-6 option. This technique uses two additional implants to provide enhanced stability while still helping many patients avoid the need for bone grafting.
During your consultation, we will determine whether Smile XZ with All-on-4 or All-on-6 is the best path forward for you. At Southern Dental Implant Center, we are committed to delivering the highest quality, most natural-looking results possible because your smile deserves nothing less.

How We Make Smile XZ Accessible
While basic dental insurance typically does not cover the full cost of All-on-4 implants, many plans will help with parts of your treatment, such as extractions, periodontal therapy, or the denture itself.
At our Brentwood dental office, we believe that cost should not stand in the way of life-changing care. That is why we offer flexible financing options so you can pay over time with monthly payments that work for your budget.
During your complimentary Smile XZ consultation at our Nashville area office, you will receive a detailed cost estimate. We will also walk you through financing solutions and coordinate with your insurance provider to maximize your benefits for any eligible portions of your treatment.
