Periodontal surgery Flashcards
What type of incision is this?
External bevel incision or gingivectomy
Type of incision?
Internal bevel incision.
starts at the surface of gingiva and is directed apically to crestal bone. Incision from which the flap is elevated
Type of incision?
Crestal incision (marginal incision)
starts at the surface of the gingival margin and directed down to crestal bone
Name the incision
Submarginal incision
Starts at surface of gingiva apical to gingival margin.
Depends on the transgingival interdental probing depth, the MG junction and the depth of palatal vault
Name the incision
Sulcular incision (crevicular, intrasulcular, etc)
starts in gingival crevice through the junctional epithelium down to bone. Regenerative surgery
Advantages of apically displaced (positioned) flaps?
Preserves the outer portion of the pocket wall and transforms it into the attached gingiva
Eliminates the pocket and increases width of attached gingiva
allows pocket reduction in areas where keratinized gingiva is limited and the internal bevel incision must be made at/close to the gingival margin
What does this depict?
Position of interdental sutures below the base of an imaginary triangle in the papilla
What is the suture pattern used?
Single sling suture
What is the suture pattern? Where is this used?
Distal wedge suture.
Anchor suture used to close flaps that are mesial or distal to a lone tooth.
What is this pattern? What is it used for?
Continuous sling suture with horizontal mattress sutures used in areas of diastema or wide interdental areas. Used for flaps involving both lingual and facial flaps
What are periosteal sutures used for?
To hold apically displaced partial thickness flaps to the periosteum.
Holding suture is horiz mattress placed at the base of the flap into the periosteum to secure it in the new position.
Then closing sutures are used to secure the apposing edges.
