Abdolreza Jamilian (Persian: عبدالرضا جمیلیان; born 1965) is an Iranian orthodontist and a USPTO patent holder[1] for devices including a method and system for treatment of maxillary deficiency using miniscrews,[2] a tongue plat,[3] and an R-appliance.

Jamilian is a member of the Iranian and European Board of Orthodontics, and known for his innovations in designing therapeutic modalities for class III malocclusion patients.

[5] Class III malocclusion is considered to be one of the most difficult and complex orthodontic problems to treat for 12 year old patients or younger.

Various types of orthodontic headgear, such as facemasks and reverse pull headgears have been used to correct maxillary deficiency; however, these extra-oral appliances have some unpleasant side-effects including the fear of being mocked by one's peers due to the bulky size of these appliances and causing downward and backward rotations of mandible which pulls the upper jaw backwards into the airway of a growing child.

[7] In the method invented by Jamilian, maxillary deficiency is corrected with the help of self-drilling titanium alloy miniscrews and class III elastics.
