Dr. Ickert is proud to limit his practice to comprehensive, aesthetic and functional rehabilitative dentistry, including both the surgical and prosthetic aspects of dental implants, as well as many other related hard and soft tissue enhancement procedures.

Due to the highly challenging nature of this specific field of practice, Dr. Ickert and his team have committed themselves primarily to this aspect of dentistry. This implies continuous, comprehensive, educational, surgical, prosthetic training, with world leaders in this field, both within North America and Europe. Dr. Ickert has completed his Master’s Program in Oral Medicine and Implantology, graduating March 2012 from the University of Muenster, Germany.

As the result of the many inherent complexities and challenges which characterize this type of dentistry, Dr. Ickert is aligned with many other specialized practitioners and technicians, both locally and throughout the world, who provide excellent support to the patient care received at the Ickert Dental Implant Centre. This has also provided several teaching opportunities to share his knowledge and experience, both locally and internationally.

The genetically pre-determined aesthetic and functional compromises, which accompany loss of tooth structure, along with the subsequent loss of hard and soft tissue, provide a significant challenge in the rehabilitative process. Dr. Ickert passionately believes, that the key to long-term success is a detailed risk-based, pre-treatment assessment and diagnosis, followed by a systemized treatment approach, increasing the opportunity for a desirable long-term outcome.

The ultimate goal for Dr. Ickert, and his dedicated team, is to identify each patient’s specific concerns and provide personalized, realistic and long-term solutions, in a professional, comfortable and caring environment, which meet and hopefully exceed the functional and aesthetic expectations of each individual patient.

The Ickert Dental Implant Centre is honoured to have the opportunity to provide this type of personalized and comprehensive care to all patients.
