Study Notes
Part 2: Periodontal Surgery - Flap Procedures
-
Main Objectives:
- Debridement of pocket epithelium and inflamed connective tissue.
- Elimination of deepened pockets (Widman).
- Minimal trauma and discomfort to patient.
-
Advantages of Flap Operations:
- Preserves existing gingiva.
- Exposes marginal alveolar bone for defect identification and treatment planning.
- Exposes furcation areas to assess involvement.
- Allows repositioning of the flap for optimal gingival margin adjustment.
- Preserves oral epithelium and surgical dressing can be used.
- Post-operative period is generally less uncomfortable than gingivectomy.
Types of Flaps
- Full Thickness Flap: Includes epithelium, connective tissue, and periosteum reflected from underneath bone (mucoperiosteal flap).
- Partial Thickness Flap: Includes epithelium and connective tissue reflected from bone and periosteum (split flap).
Original Widman Flap
- Developed in 1918 by Leonard Widman.
- Designed to remove pocket epithelium and inflamed connective tissue facilitating root surface cleaning.
- Advantages reported include less patient discomfort due to healing by primary intention and re-establishment of proper alveolar bone contour in angular bony defects
Modified Flap Operation
- Introduced as a modification to Widman's original technique.
- Does not involve extensive removal of non-inflamed tissues or apical displacement of the gingival margin.
- Useful for anterior regions for esthetic reasons or in cases of intrabony defects, allowing for potential bone regeneration.
Apically Repositioned Flap
- Developed in the 1950s and 1960s.
- Emphasizes maintaining an adequate zone of attached gingiva after surgery.
- Nabers (1954) and Friedman (1962) described techniques and techniques for preserving gingiva and proposed this technique as a suitable alternative.
Technique Descriptions (Friedman 1962)
- Incision: A reverse bevel incision made, using a scalpel. The depth and width of the incision is based on pocket depth and gingival thickness. Scalloped incisions are favored when a maximal interproximal bone coverage is intended.
- Mucoperiosteal Flap Elevation: Raising the mucoperiosteal flap beyond the mucogingival junction to allow for apical repositioning.
- Bone Crest Recontouring: Ensuring the alveolar bone crest is recontoured to its normal form at the apical level .
- Flap Repositioning: Repositioning the flap to the level of the recontoured alveolar bone crest, and securing it in place.
Additional Flap Techniques
- Modified Widman Flap (Ramfjord and Nissle 1974): An open flap curettage technique aimed at proper pocket elimination without extensive bone recontouring procedures. Focuses on minimizing trauma to bone and soft tissue while ensuring adequate soft-tissue coverage.
- Papilla Preservation Flap (Takei et al. 1985): A technique aimed at soft-tissue preservation in interdental areas during surgery for osseous defects. Uses intrasulcular incisions (not through the papillae) as a means to preserve interdental tissue following surgical intervention.
