    Study Notes

    Flap Classification

    • Flaps can be classified based on the amount of tissue content: full thickness (Muco-periosteal flap) or partial thickness (split thickness or mucosal flap)
    • Flaps can also be classified based on final placement: non-displaced or displaced
    • Papilla management: conventional or preservation

    Full Thickness Flap

    • Also called Muco-periosteal flap
    • Lifts both mucosal tissue and periosteum
    • Indicated when access to bone is needed for osseous resection or modifying bone surface
    • Contraindicated in areas with thin alveolar bone

    Partial Thickness Flap

    • Also called split thickness or mucosal flap
    • Lifts only mucosal tissue, leaving periosteum intact
    • Provides vascular bed for grafting recipient site
    • Used when attached gingiva needs to be preserved

    Displaced Flaps

    • Involve vertical incisions to increase mobility and allow repositioning
    • Can be full thickness or partial thickness
    • Attached gingiva must be totally separated from underlying bone
    • Palatal flaps cannot be displaced due to absence of unattached gingiva

    Papilla Management

    • Conventional: papilla is split between two adjacent teeth
    • Indicated when interdental space is narrow or extra reflection is needed
    • Downsides: formation of black triangles
    • Preservation: involves incisions around papilla to limit black triangle formation

    Flap Designs and Applications

    • Corona lead position flap: displaced flap for covering recession defects
    • Laterally positioned flap: displaced flap for small single tooth recession defects
    • Epically positioned flap: displaced flap for pocket reduction and preserving attached gingiva
    • Modified Widman flap: for instrumentation during scaling and root planing therapy
    • Undisplaced flap: most commonly performed flap in periodontal surgery for temporarily removing soft tissue during surgery
    • Semi lunar flap: conservative flap design for apico-ectomies
    • Envelope flap: most commonly raised flap in oral surgery for tooth extractions
    • Distal wedge procedure: for reducing pocket depth distal to terminal molar

    Grafts

    • Free gingival graft: used to widen band of keratinized tissue around teeth
    • Donor site: posterior hard palate
    • Recipient site: where graft is placed
    • Connective tissue graft: used to improve root coverage for recession defects
    • Donor site: posterior hard palate
    • Recipient site: prepared with split or full thickness flap with dissection beyond mucogingival junction
