Retrospective study 146 19.5 years (implantations); 22.8 years (explantations) 104 implantations (33 M/71 F); 44 explantations (9 M/35 F) Median and paramedian Complication associated with the implantation: no primary stability, prolonged pain, secondary bleeding, perforation of nasal floor, necrotic mucosa, sensory impairment - Palatal implant (Orthosystem; Institut Straumann AG, Basel, Switzerland). Self-tapping Placed according to the Straumann guidelines for respective palatal implants. After local anesthesia, the palatal mucosa was either removed with a punch and an elevator or by open flap technique. After marking the center of the site with round drill, the hole was drilled by spiral drills. The self-tapping implant was inserted by hand with a ratchet. After the orthodontic treatment the palatal implant was removed using trephin
