A Prosthodontist is a certified dentist specialist in Prosthetic and Implant Dentistry.  This specialty requires an additional 3 years of University training to obtain a Postgraduate Dental Degree.  This specialty is completed after the standard 4 years of dental school.  The curriculum involves an intensive study of complex  reconstructive and implant dentistry. 


Prosthodontic treatment at our practice is comprehensive but may collaborate with other dental specialties.  Our goal is to always create an optimal result.  An additional feature is the intimate relationship the Prosthodontist has with the dental laboratory and its dental materials.  This knowledge and experience is essential for creating comfortable, esthetic, and predictable dental restorations.

Prosthodontists have special expertise with dental implants, crowns, veneers, bridges, dentures, complete reconstruction, TMJ disorders and complex multidisciplinary treatment.  One of the specific areas of knowledge is with the "Bite," also known as the occlusion.   This is a common patient concern and requires careful management.  Prosthodontists are well adapted to deal with the care of simple and complicated dental scenerios.
