Our Dental Practice History Pinnacle Center Dental Implants & Periodontics
Dr. Silberg opened his practice in July of 1980, and named it The Silberg Center of Dental Science. The original office was located in the Robinson Professional Building. As a newly graduated specialist, Dr. Silberg built his practice around his chosen specialty of periodontics.
Dr. Silberg felt that by creating a new practice, rather than purchasing an existing one, he would have the opportunity to implement his unique philosophy and vision of healthcare. Thus, with 0 patients of record, Dr. Silberg began his practice that has now grown into what it is today.
The early years were difficult with the 1980s economy in recession. The Pittsburgh area suffered greatly as many of our steel mills closed. Through Dr. Silberg’s tireless efforts and his commitment to excellence, the practice continued to grow.
By the mid-1980s it was apparent that the office space was too small and there was no room for expansion. The Tower View office building was being built across the street and the decision was made to move to a larger office suite to better serve our patients.
Dr. Silberg designed a new space, and in September of 1987, he moved across the street to the Tower View building at 6200 Steubenville Pike. The building is named Tower View because of the adjacent township water tower, which is in plain view.
Between 1984 and 1985, the dental implant field went through a radical redesign. Dr. Silberg began to study the new dental implant technology and believed that it was a safe and effective treatment. He then began to obtain the necessary training that was needed to be able to place implants for his patients. He placed his first implants in 1984. A gentleman named Romano received them, and the implants are still in place and functioning to this day! In the years since Dr. Silberg has seen the incredible benefits that dental implants provide and has now restricted his practice to implant dentistry and periodontics.
In the years that followed, the practice remained on the leading edge of science and technology:
- 1987: We moved into our current office location.
- 1988: The office became computerized.
- 1998: New low radiation digital X-ray sensors were added to the practice.
- 2003: Platelet technology was utilized to improve healing.
- 2010: LANAP laser was introduced to treat gum disease.
- 2011: Cone beam 3D CAT scanning was added to improve implant success.
- 2018: Dr. Katherine L. Roll joined the practice as an associate periodontist.
- 2019: The Dentin Grinder was added to use a patient’s own teeth to enhance bone healing.
- 2020: The practice celebrated 40 years of serving people’s needs from the tri-state area.
- 2021: The Silberg Center for Dental Science became Pinnacle Center – Dental Implants & Periodontics.
- 2022: After 40 years, Dr. Silberg retired from practice.
As Pinnacle Center – Dental Implants & Periodontics, we plan to continue to serve patients from all over the Pittsburgh and greater Southwestern Pennsylvania area.
Never again suffer from the use of dentures, or the pain and embarrassment of missing teeth. Ever!
