<p>PURPOSE:To perform perforation with high accuracy and to enhance the percentage of success (bonding percentage with a bone) of a dental implant, by forming a fundamental member as a ready-made article having an almost inverted U- shape cross-section and making it possible to mechanical fix the fundamental member and a guide or slide member. CONSTITUTION:This guide apparatus consists of a columnar guide bar 2a being one kind of a guide member and a fundamental member 1 having an almost inverted U-shape cross-section and the lower end of the guide bar 2a is fixed to the fundamental member 1 by a ball joint 6. Since one guide bar 2a is used and can perform precession, horizontal movement and other motion around the lower end thereof, the positional control range of a handpiece 4 becomes large.</p> |
