PATIENT IMPACT: “During my residency in New York, I provided a patient with implant overdentures to stabilize her loose dentures. Two weeks later, she returned ecstatic to share her testimonial with our staff. She was extremely happy with the results and was in tears. She never thought in all her life she would be able to eat any of her favorite foods, like steak or corn-on-the-cob. Every time she returned for dental checkups, she thanked me for how much I improved her quality of life. She is now able to eat all of her favorite foods.”
