    Study Notes

    Week 1 - August 16, 2024 - Principles of Routine Exodontia

    • Elevating the periosteum is a crucial initial step in extractions. A No. 9 periosteal elevator is used to reflect bone in a single layer.
    • The No. 15 scalpel is commonly used in oral surgery. Comes with disposable blades, often used with a pen grasp technique.
    • Rongeurs are tools for osteotomy, removing small amounts of bone in multiple bites. Needle holders are used for handling blades, and hemostats are not used for suturing.
    • Post-extraction socket care is critical. Wet gauze, held in place by biting down, is recommended for 20 minutes. Avoid suctioning the socket.

    Adult Maxillary Expansion Lecture

    • Maxillary arch expansion is needed for correcting skeletal imbalances, dentofacial irregularities, and malocclusions. Identifying these imbalances early is essential.
