About us

The Association for Treatment Planning in Aligner Orthodontics aims to establish an active interdisciplinary collaboration between orthodontists and dental technicians with the goal to increase efficiency and quality of digitally planned treatments for clear aligner systems. We achieve this through congresses, publications and educational events aimed to increase practical knowledge around digital treatment planning.

The Association was launched in 2019 and, true to its interdisciplinary nature, combines the knowledge, passion and drive of two orthodontists with tremendous knowledge on aligner treatments – Dr Udo Windsheimer and Dr David Raickovic – and two certified master dental technicians with extensive experience in digital treatment planning: Matthias Peper and Björn Reiners.
