Introduction: Bimaxillary protrusion is a deformity characterised by protrusive and proclined maxillary and mandibular incisors. Successful treatment of this condition in adult patient is one of difficult biomechanical case in orthodontics.Orthodontic anchorage system is better explained by newtons law of motion.The objective of this study was to compare the amounts of anchorage loss and retraction of anterior tooth using conventional tooth anchorage and skeletal anchorage in individual with bimaxillary protrusion. Materials and methods: The study consist of two groups of 25 patients in group A(conventional anchorage) and 25 patients in group B(skeletal anchorage system). This study was used to compare the anchorage loss and amount of anterior retraction in bimaxillary deformity treated by conventional tooth anchorage versus skeletal anchorage system(SAS). Results: The result showed that skeletal anchorage group had greater anterior tooth retraction and less maxillary molar mesialization than the conventional group. Conclusion: Although difference in anchorage system could not reduce the duration of treatment, in case of bimaxillary cases the skeletal anchorage sytem can produce more successful outcome. The succees rate and stability of skeletal anchorage group was more than traditional anchorage group Keywords: Anchorage loss, Skeltal anchorage, bimaxillary protrusion
