A study of the mechanical strength of miniscrews and miniplates for skeletal anchorage

Abstract: Background/purpose: The concept of miniscrews-miniplates has been used in orthodontic practice to reinforce skeletal anchorage. The aim of this study was to evaluate the mechanical strength of miniplates in vertical and horizontal pull-out tests. Materials and methods: The insertion torques and pull-out strengths of 10 miniscrewe miniplate orthopedic sets (five for the vertical and five for the horizontal pull-out tests) within synthetic bone were determined. Each miniscreweminiplate orthopedic set was compose… Show more

“…The strength of the miniplate inserted into the jawbone depends on the thickness and number of plates. In laboratory studies, the yield strength of miniplates has been reported to be approximately 100 N in the vertical direction and 230-250 N in the horizontal direction [11,12]. This is sufficient strength to resist masseter muscle pulling in cases of unilateral maxillary-cheek bone fracture.…”
