Title: An evolutional approach to lingual treatment of various types of malocclusions using Ortho Anchor 


The introduction of anchor screws into orthodontic practice allows application of orthodontic forces in various directions for intrusion and extrusion of teeth and movement of the entire dentition to produce orthopedic changes even in adult patients. Particularly in lingual orthodontics, anchor screws can be used effectively due to the characteristics of lingual mechanics. Excellent results that are esthetically pleasing and functional can be achieved with consideration for the following aspects: 1) torque and tip of brackets used, and arch form; 2) effective mechanics with cant correction in mind, and wire sequence; 3) incisor display with attention to post-treatment aging; and 4) finishing conducive to functional and occlusal stability. This is in line with the treatment objectives proposed by Dr. Tweed: 1) balance and harmony of facial lines, 2) stability of the dentition after treatment, 3) healthy oral tissues, and 4) an efficient chewing mechanism. It is intriguing that these objectives in the orthodontic philosophy proposed 75 years ago hold true today. As the saying goes, “discover new things by taking lessons from the past.” Various types of malocclusions treated by incorporating these 4 aspects will be presented.
