The Recent About Growth Modification Using Headgear and Functional Appliances in Treatment of Class II Malocclusion: A Contemporary Review

In this review of literature we are discussing growth modification in treating classII malocclusions. The prevalence of class II malocclusion is very high ranging from 15% to 20%, in some regions in the world it is considered the most common malocclusion, others consider it as the second common malocclusion. It is estimated that one fourth of all patients, and one third of all children, are treated in two phase treatment .Our target here is the growing patients trying to get benefit and advantage from there growth potential.There is a lot of debate and controversy regarding the optimal time of treatment, the type of appliance that produce the best treatment outcome. Despite recent questions of the effectiveness of early treatment, it isgenerally recognized that the use of growth modification still has a place in modern orthodontic practices. The aim of this review is to study growth modification either by restriction of maxillary growth using the head gear or stimulating the mandibular growth using the functional appliances. IN this review we discuss the orthopedicappliances usages, advantages, disadvantages of each appliance and the optimal time of treatment. We are trying not just to achieve class 1 dental occlusion but also to improve the facial profile of the patients, which will improve the patients psychosocial and patient’s self-esteem. In addition to that it is very important not to forget that in orthodontics we are working on three planes not just we are trying to understand that growth modification for class II malocclusion doesn’t mean just adjusting the anterior posterior plane but also we will try to treat the vertical and transverse discrepancies. Key points: Class II malocclusion, functional appliance, growthmodification, headgear appliance.
