How precise is the placement of the Spider Screw when roots are in close proximity? Is it possible to infringe or damage the adjacent roots?
Sometimes the space between the roots of adjacent teeth is small and we need to find a larger space or to prepare the site moving the teeth apart before inserting a Spider Screw. Having at least 3 mm of space, we can insert a Spider Screw of 1.5mm of diameter without disrupting the roots of adjacent teeth. A precise x-ray (Periapical x-ray with parallel technique) is needed when a narrow space is available and sometimes a surgical guide is also useful; especially in difficult places to access.
