To evaluate the skeletal and dent alveolar effects produced by reverse twin block appliance in class III malocclusion in growing patients. A systematic search was conducted using electronic search of PubMed, Google Scholar, Google, manual search using Institutional library from 1st January 2000 to 31st December 015. RCT, Clinical trials and Case reports were selected. These studies evaluated the effectiveness of reverse twin block appliance. 9 articles have been used for detailed evaluation in this systematic review after assessment of full text. Results showed skeletal changes like increase in SNA, decrease in SNB and ANB, increase in anterior vertical dimensions, mandibular length and height along with (Frankfort mandibular angle) FMA and (Mandibular plane angle) MPA. Dental changes included: proclination of upper anteriors, retroclination of lower incisors, class I molar and canine relations. Soft tissue changes were improvement in the profile of the patient with reduction in the concavity of the profile. In developing class III cases having dental and skeletal imbalance, treatment should be recommended at an early age. Early treatment with reverse twin block reduces developing skeletal imbalance and decreases the need for comprehensive orthodontic treatment at a later age. The available evidence on this topic is scarce. No studies till now were found to be identical to this review describing the cephalometric soft tissue and hard tissue pre and post treatment changes with reverse twin block.
