Biological Drilling: Implant Site Preparation in a Conservative Manner and Obtaining Autogenous Bone Grafts

Balkan Journal of Dental Medicine, 2018
Background/Aim: The drilling process for insertion of an implant should be as conservative as possible, as not to damage the future implant bed. If this drilling is conservative additional bone can be obtained to be used afterwards, during the same ...
