Specialized Oral Surgery Procedures

Have you lost multiple teeth, or do you anticipate the need to have many unhealthy teeth extracted? Keystone OMS provides full arch restoration, allowing you to regain full form and function. Full arch restoration uses the All-on-4 dental implant system to ensure long-term results, including artificial replacement teeth that look and behave like natural teeth.

If you have experienced tooth loss, you should pursue dental restoration sooner rather than later, preventing the further degradation of jawbone. Dental implants represent the gold standard for tooth restoration. They allow you to maintain your natural smile and maintain good oral health over a lifetime.

In addition to our robust oral surgical options, Keystone OMS also provides a number of surgical and non-surgical treatments to help address cosmetic issues. Our experienced oral surgeon is here to assist with the injection of BOTOX® and dermal fillers, along with facial treatments, scar revision, chin augmentation, and a variety of cosmetic surgeries.

“He is fantastic and so is his staff. He was helpful and informative about all aspects of the experience. The best part for me is they always took the time to address my 14-year-old and answered any questions or concerns he had. Made him feel very comfortable throughout the whole process.”
