Why have a periodontist, such as Dr. Donovan place your implant? Dr. Donovan has received extensive training in dental implant placement, and also the management of the hard and soft tissue prior to implant placement. He also has extensive training in the esthetic management of dental implants. Periodontists receive some of the most extensive dental implant training in the dental profession. We also use multiple dental implant systems such as Straumann and Astra dental implants which are some of the most well-studied and documented implants that are available.
