1 Instruments in Oral Surgery Jan 18, 2008

2 Hemostats vs. Needle Holders Hemostats Hemostats Used for placing and removing surgical blades Used for placing and removing surgical blades Needle holders Needle holders Have gold loops Have gold loops Used specifically for pushing needles and suturing Used specifically for pushing needles and suturing

3 Hemostats vs. Needle Holders

4 Full Thickness Flaps Mucosa, Submucosa and Periosteum Mucosa, Submucosa and Periosteum Submucosa contains nerves, arteries, veins and lymphatics Submucosa contains nerves, arteries, veins and lymphatics We raise full thickness flaps in O.S. We raise full thickness flaps in O.S. Less swelling Less swelling Less bleeding Less bleeding Less pain Less pain
