Abstract :

Background: – skeletal class III malocclusion in growing children are usually treated with the help of orthopaedic appliance like Facemask (FM), FM along with Rapid maxillary expansion (RME), chin–cup, mandibular headgear and Tandem traction bow appliance (TTBA) Objective: To compare the effectiveness of FM and TTBA in improving the facial profile for the treatment of skeletal class III malocclusion. Data Sources: An electronic literature research was performed within PubMed and Google da–tabases from 21st May till 22nd Sept.2017. Study eligibility criteria: Case report and case series in English language including FM and TTBA appliances treatment for class III malocclusion reporting clinical and cephalometric outcomes were included. Participants: Studies that provided information for age group 4–13 years of age of either sex. Intervention: TTBA appliance was compared with FM in the facial profile improvement in the treatment for skeletal class III malocclusion. Conclusion: The traditional FM protrudes the maxilla with pure extra oral anchorage with mini–mal dentoalveolar changes. The TTBA is an intra oral tooth borne anchorage system that combines skeletal and dentoalveolar movement. Patients prefer the intraoral TTBA compared to the FM which frightens some patients due to its physical appearance and bulkiness which frequently causes skin irritation from the anchorage pads on the chin and forehead. FM has a better craniofacial adap–tation after the treatment compared to TTBA
