Abstract:

Orthodontic treatment utilizing mini implants has become a common practice especially in anchorage demanding situations. Placement of mini-implants within a known safety zone could significantly reduce the accompanying risks particularly in relation to neighboring structures. In addition to investigations employing advanced radiography such as cone beam computerized tomography, the often prescribed panoramic film has also been used to complement scientific evidence in order to map out the safety zone for common mini implant placement sites, one of which is the buccal surface between the second maxillary premolar and first maxillary molar. The measured safety zone thus mapped out using computer software on digital panoramic tomographic radiographs in the site between the second premolar and the first molar in the maxilla of mongoloids, can be a useful a guide to the clinical practice of placing mini-implants for orthodontic treatment purpose in the mongoloid population.
