The Modified Widman Flap Technique is a periodontal surgical procedure designed to remove subgingival plaque and calculus (below the gumline) and reduce periodontal pocket depths. It allows for better access to the root surfaces of teeth and the surrounding bone for cleaning and improving the overall health of the gums.
Techniques :
1. Incision:
- Three incisions are made in this procedure. The first is an internal bevel incision about 0.5-1 mm from the gingival margin. This incision is made to expose the underlying bone and periodontal structures.
2. Flap reflection:
- A minimal reflection of the gingival tissue is done to gain access to the root surface, alveolar bone, and periodontal pocket. The flap is elevated to the extent necessary for visibility and access.
3. Debridement:
- After reflecting the flap, the root surfaces are cleaned of any calculus, plaque, and infected tissue. The bone may also be reshaped if necessary.
4. Flap repositioning:
- Once the area is cleaned, the flap is repositioned to its original position and sutured back into place. The goal is to achieve primary closure without excessive stretching of the gingival tissues.
5. Healing:
- Postoperative care includes managing infection, swelling, and discomfort. The area is monitored for healing and potential regeneration of periodontal structures.
The Modified Widman Technique is less invasive compared to other periodontal surgeries and focuses on thorough cleaning rather than extensive tissue removal or reshaping. The primary goal is to create an environment conducive to healing by reducing pocket depths and eliminating bacteria.
