About me

I am at the orthodontic clinic daily, where I meet my patients and work as a clinical teacher in undergraduate education for dental students in semesters 7 & 8. In addition, as a lecturer at the Orthodontic Unit of the Department of Dental Medicine, I hold lectures and seminars in dental education. Here I also conduct my research, partly my projects or collaborations with other researchers.

Research description

In my research, I focus primarily on new digital technologies that use 3D methods and the application of algorithms or artificial intelligence. I use these new techniques mainly in clinical projects in the following:

• Skeletal anchorage, a method where we can control tooth movements with the help of tiny screws in the jawbone.
• Health economic evaluations, where we analyze what cost or savings the introduction of a new treatment method entails.
• Registry studies with a focus on epidemiology and socio-economics.
• Measurement methods with a focus on 3-dimensional techniques.

Ongoing researchprojekts

• Validity and reliability of three-dimensional measurement methods in dentistry
  • Niels Ganzer
• Accuracy of three-dimensional scanning of the palate - comparison of direct intraoral scanning versus indirect scanning - Noggrannhet av tredimensionell skanning av gommen - jämförelse av direkt intraoral skanning kontra indirekt skanning
  • Berfin Shamlou, Reinhilde Jacobs, Niels Ganzer
• Sex distribution among children and adolescents who receive publicly financed orthodontic treatment in Gävleborg County - Könsfördelning bland barn och ungdomar som får skattefinansierad ortodontisk behandling i Gävleborgs län
