Or
Write short answer on circumferential supracrestal fibrotomy.
Answer. Since the procedure was given by Edward it is named as Edward’s procedure

• This procedure is carried out to help minimize the extent of rotational relapse of teeth.
• It is also known as supracrestal fibrotomy or circumferential supracrestal fibrotomy or sulcus slice procedure or pericision.

Principle of Edward’s Procedure

• Relapse after orthodontic treatment occur due to rebound of network of elastic supracrestal gingival fibers.
• As teeth move to new position, these fibers are stretched and remodelling of these fires take long time.
• This procedure involves elimination of pull of elastic supracrestal gingival fibers by sectioning these fibers.
• Teeth are held in the corrected position when the fibers heal, thereby reducing the relapse caused by elasticity of the gingival fibers.

Edward’s Procedure

• Under local anesthesia, sharp point of the fie blade (No 15 B.P blade) is inserted into the gingival crevice till the alveolar crest of the bone.
• Blade should be kept parallel to the tooth surface.
• At around the circumference of the tooth, blade is passed. This severs the fibers connecting tooth to the gingival soft tissues.
• Interproximal cuts should be made on each side of the rotated tooth.
• At along the labial and lingual gingival margins cuts are also given. If the labial gingiva is thin, this cut is removed.
• Pericision is generally undertaken as adjunctive retention procedure after correction of rotations.
