Meet the Doctors

Boston Prosthodontics consists of Dr. Kenneth A. Malament, a world-renowned Prosthodontist, Dr. Hans Peter Weber, a prosthodontist and periodontist, Dr. Alissa Mariano, a prosthodontist, Dr. Scott Lightfoot, a periodontist. Dr. Dan Nathanson has since retired from the practice, and we are extremely grateful for the kindness and leadership he has provided. Dr. Malament states that dentistry that is esthetic and functioning comfortable to the patient are important clinical objectives. The knowledge within dental technology, dental science and dental practice has dramatically expanded, leading to better quality, artistry and more standards-based clinical applications. Ceramics are the most consistently predictable esthetic dental material. Today, prosthodontists working with other dental specialists can offer more treatment options for patients complex problems.

Drs. Malament, Weber, and Mariano are recognized by the ADA as specialists. They have extensive training in comprehensive care, material science & quality esthetic dentistry for implant restorations, crown & bridgework, dentures, partial dentures & Sleep Disorders and TMD (headaches & jaw pain). Fabricating all custom dental work onsite, Prosthodontic Associates features a dental laboratory with Master Dental Technologists.
