Research Interests

Dr Norton is widely published in the literature with particular interests in the areas of implant design, primary stability, immediate loading, and etiology and treatment of peri-implantitis.

Dr Norton’s work on implant-abutment joint design in the 1990s led to a paradigm shift in the understanding of the mechanical advantages of the internal conical connection which underpin the design of many of today’s modern dental implants. Through his collaborative work he has helped to design one of the most advanced implant connections currently available.

In addition, research at his facilities in London has principally focused on primary stability and its relevance in the success of implants subject to immediate loading. Ongoing evaluation of the influence of insertion torque and resonance frequency analysis continues to challenge currently established dogma.

More recently research efforts have also focused on the etiology, and treatment of peri-implantitis. This is a collaborative research effort with colleagues at UPenn in the Department of Periodontology.
