SALDARRIAGA-VALENCIA, Jenny Angélica; ALVAREZ -VARELA, Emery  and  BOTERO-MARIACA, Paola Maria. Treatments for skeletal Class II malocclusion combined. CES odontol. [online]. 2013, vol.26, n.2, pp.145-159. ISSN 0120-971X.

Class II malocclusion present a variety of dental, skeletal and functional configurations, based on the anteroposterior position of the maxilla and mandible, position of maxillary and mandibular teeth and the vertical pattern of class II patients, being the retrognatism the most prevalent characteristic in these patients. The etiology is multifactorial including genetic, familial components and environmental factors. The experience of several experts has demonstrated the need to combine different therapeutic means to achieve its full effect. Intra and extraoral appliances used for the correction of skeletal class II malocclusion include Hawley plates , bite planes, headgear, functional appliances (activators, bionator, twin -block, Frankel) , buccal screens, combination of functional with extraoral appliance, mini-screws, and more specifically in the case of mandibular posterior rotator patients the use of high-pull headgear combined with functional appliances with posterior bite blocks and the most recent treatment, orthodontic miniscrews. Treatment success depends on constant monitoring and evaluation of growth and development of growing Class II patients. This article describes the case of a patient diagnosed with skeletal class II with a vertical growth pattern.
