The document describes various surgical instruments used in oral surgery. It discusses diagnostic instruments like mouth mirrors and probes. It also covers instruments for gaining surgical access such as scalpels and blades, and instruments used for retraction like skin hooks and retractors. Additionally, it mentions instruments for reflecting flaps like periosteal elevators and stripers as well as instruments for holding tissues like artery forceps and Adson's tissue holding forceps. The objectives of the armamentarium are to provide an optimal surgical field, optimal visibility, and decrease surgeon strain.
