Bone scraper acc. Dr. Bernard Guillaume
The bone scraper has an extended working area for bone curettage so that a large volume of bone substance can be obtained. The instrument`s widened handle fits perfectly in the hand to ensure that the instrument is supported and controlled securely during bone curettage. The shortened curved shaft ideally meets the surgeon`s needs in handling the jaw under different anatomical conditions
