Used to mark and perforate the cortical plate. Designed in three lengths: the short one permits better access in posterior regions, long for cases in which the interdental space limits drilling
access, and extra-long marked at 8.5, 10, 13 and 15mm.The BTI initial drill allows marking the neoalveolus and allows slight alteration of drilling direction, as well as changing direction within a
receptor site or in an irregular ridge.Manufactured of surgical grade stainless steel.
