A. Korrodi Ritto graduated in dentistry in 1988. Received the PHD degree in 1997. The title of Specialist in orthodontics was obtained in 1998. He works in private practice at Mouzinho Albuquerque 115 1º, 2400-194 Leiria, Portugal. He is the inventor of the Ritto-Appliance. He wrote more than 50 articles in orthodontic journals around the world, and displayed many clinic tables and posters at AAO, EOS, and Portuguese Societies.

The Ritto-appliance was developed to overcome the drawbacks with the regular fixed functional appliances. The appliance can be fitted in 5 minutes and removed in half that time. More than an appliance it is a philosophy. See the manual for details.

The author uses in his philosophy other tools to improve the treatments: lingual pearl, and micro implants. He wrote a book about micro implants, and is co-author of other books about the same subject and fixed functional devices: see literature.
