Dr. Seth Kimmelman at his Downtown, Colorado Springs Dental office offers multiple options for Implant Retained Dentures. All-on-four is an option where the custom made denture is screwed into the implants and can only be removed by Dr. Kimmelman. This is the “stays-in” option. Dr. Kimmelman uses a much more life-like and stronger material than most other dental offices. The screwed-in teeth are made of zirconia. Because of the superior strength of the zirconia vs. acrylic teeth, they are much smaller, less bulky and made to last unlike acrylic teeth over metal bars.
