摘　　要：Objective: The aim of this study was to compare the effect of face mask (FM) and Maxillary Bite Block (BB) in skeletal class III patients during mixed dentition with control group of the same class during their growth. Materials & Methods: Forty-two patients were selected based on clinical and cephalometric examination, with age ranged from 6 to 8 years according to definite criteria. Patients were classified into two groups: treated and control groups;all records were taken for every patient. Lateral cephalometric films were traced before and after treatment and analyzed. Results: Intermaxillary skeletal variables showed significant improvement in the treated group with an average increase of ANB angle (Maxilo mandibular difference angle) of 3.14°and an average increase in wits appraisal 2.15 mm. Conclusion: The study concluded that, treatment with face mask and maxillary bite block induced significant dentoskeletal changes.Objective: The aim of this study was to compare the effect of face mask (FM) and Maxillary Bite Block (BB) in skeletal class III patients during mixed dentition with control group of the same class during their growth.
