Abstract
The split crest technique is used in implant. Where the alveolar bone is thin, a partitioning method is used according to the buccolingual diameter, which preserves the height of the alveolar bone, makes forming of the implant easy and produces an esthetic prosthesis. In addition to alveolar bone partitioning, this paper explains the bone expander, which alone can eliminate the discomfort of hammering. It is for this reason that the Bone ExpanderTM (Patent Pending No.117749) was developed.
There are three wings at the end of this tool, the expander, of which bilateral wings are 2.0 mm and center wing is 2.5 mm wide. Operating this expander makes it easy for the alveolar bone to be expanded to the correct width to match the purpose. This paper explains the construction and clinical application of the new tool.
