**7.3 Partsch flap**

The semilunar (Partsch) flap is a variant involving a submarginal incision in the alveolar mucosa to form a crescent- or semilunar-shaped flap (**Figure 24**). The semilunar flap is almost exclusively used for the maxillary canines [21]. Care is required to avoid performing the incision above the bone defect.

Advantage

• Small incision suitable for upper canine surgery
