Apex is proud to offer the innovative restorative process, all-on-four to our clinicians. There are numerous benefits that come with this implant solution, especially when paired with our Crystal® Ultra hybrid. This treatment is successful through the use of two straight anterior implants and two angled posterior implants, which can be angled up to 45°. This is a stable option for patients. The tilted posterior implants make this a graftless solution because the patient's available bone is optimized.
