TREATMENT OF PATIENTS WITH OCCLUSAL CANTING USING ORTHODONTIC MINISCREW SYSTEM FOR MAXILLARY MOLAR INTRUSION

Abstract

Dentoalveolar vertical deformation has to be treated by intrusion with surrounding bone and tissues safety. More than 50% of orthodontic patients have lack of one or more teeth with dentoalveolar deformation. Removable orthodontic appliances are not able to intrude teeth with necessary long-lasting force, but mostly move abutment teeth inversely and extrude them. Optimal method used for upper teeth intrusion has to consist of non-invasive temporary anchorage devices and force that moves teeth fast but carefully, with periodontal tissues and surrounding bone safety. Aim - to justify the use of orthodontic miniscrews as temporary anchorage devices for occlusal canting with dentoalveolar component treatment. Materials and methods. Intrusion technique has been developed. It moves the teeth with elastic chain to two miniscrews. The volume of the surrounding bone and periodontal tissues after intrusion is the same as before the movement; the dental arch has not changed after the teeth movement; this method of intrusion is less traumatic and is done in shorter time. Conclusion. Developed intrusion method justifies the use of miniscrews and improves upper teeth intrusion making it faster, less traumatic and safer for surrounding tissues and teeth.
