We were referred to Dr. Mastrovich by our Mom’s dentist to diagnose and repair two broken implant abutment screws for my 84-year old mother. Mom’s case was challenging, as it was not initially clear why the screws fractured after only 9 months from the original implant surgery. Dr. M. was exceedingly professional and diligent in determining the cause of the problem (wrong-sized screws were installed by the original dentist). He took exceptional care of our Mom through four appointments, resulting in the successful removal of the fractured screws (while preserving the implants) and the installation of the correct parts. We are very thankful for the successful outcome. More than twelve hours of dental work for anyone is no fun, especially someone elderly. But Dr. M. and his staff (Lori and Debra) treated Mom with tremendous compassion and courtesy. We highly recommend Dr. Mastrovich.
