Success Rate of the Miniscrews in the Mandibular Buccal Shelf

"Each patient received miniscrews in both sizes. The same orthodontist (M.S.) performed all the insertion procedures. Miniscrews were always placed in the mandibular buccal shelf, laterally to the first and second molar interproximal area, with angulation 30 degree to the bone surface, meaning that miniscrew angulation should be approximately the same as the axial inclination of the adjacent molar. Miniscrews were loaded with orthodontic force 2 weeks after the surgery. The investigated factors were:~* long-term success rate of the miniscrews in the buccal shelf of the mandible (miniscrews were considered long-term stable if they served as an anchorage until completion of mandibular distalization, at least 9 months);~* peri-implantitis development (enlargement of the gingiva and/or redness and/or tendency to bleed);~* the patient's report of pain lasting longer than 48 hours after miniscrew insertion."
